Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	1. BASIS OF PRESENTATION Pioneer Power Solutions, Inc. and its wholly owned subsidiaries (referred to herein as the “Company,” “Pioneer,” “Pioneer Power,” “we,” “our” and “us”) manufacture, sell and service a broad range of specialty electrical transmission, distribution and on-site power generation equipment for applications in the utility, industrial, commercial and backup power markets. The Company is headquartered in Fort Lee, New Jersey and operates from five (5) additional locations in the U.S. for manufacturing, centralized distribution, engineering, sales and administration. NASDAQ Listing On September 24, 2013, the Company completed an underwritten public offering of 1,265,000 shares of its common stock at a gross sales price of $7.00 per share, resulting in net proceeds to the Company of approximately $7.9 million, after deducting underwriting discounts and commissions and other offering expenses. In connection with the public offering, the Company’s common stock began trading on the Nasdaq Capital Market under the symbol PPSI. Segments In determining operating and reportable segments in accordance with ASC 280, Segment Reporting (“ASC 280”), the Company concluded that it has two reportable segments, which are also our operating segments: Transmission & Distribution Solutions (“T&D Solutions”) and Critical Power Solutions. Financial information about the Company’s segments is presented in Note 17 – Business Segment, Geographic and Customer Information. Sale of Transformer Business Units On June 28, 2019, the Company entered into a Stock Purchase Agreement (the “Stock Purchase Agreement”), by and among the Company, Electrogroup Canada, Inc., a wholly owned subsidiary of the Company (“Electrogroup”), Jefferson Electric, Inc., a wholly owned subsidiary of the Company (“Jefferson”), JE Mexican Holdings, Inc., a wholly owned subsidiary of the Company (“JE Mexico,” and together with Electrogroup and Jefferson, the “Disposed Companies”), Nathan Mazurek (Chief Executive Officer of the Company), Pioneer Transformers L.P. (the “US Buyer”) and Pioneer Acquireco ULC (the “Canadian Buyer,” and together with the US Buyer, the “Buyer”). Pursuant to the terms of the Stock Purchase Agreement, the Company agreed to sell (i) all of the issued and outstanding equity interests of Electrogroup to the Canadian Buyer and (ii) all of the issued and outstanding equity interests of Jefferson and JE Mexico to the US Buyer (the “Equity Transaction”), for a purchase price of $68.0 million. Included in the purchases price, the Company received two subordinated promissory notes, issued by the Buyer, in the aggregate principal amount of $5.0 million and $2.5 million, for a total aggregate principal amount of $7.5 million. During the fourth quarter of 2019, the Company and the Buyer, pursuant to the Stock Purchase Agreement, completed the net working capital adjustment, which resulted in the Company paying the Buyer $1.7 million in cash and reducing the principal amount of the $5.0 million Seller Note to $3.3 million. The Company has revalued the notes for an appropriate imputed interest rate, resulting in a reduction to the value of the notes at December 31, 2019 of $651, for a carrying value of $5.1 million, which is included within other long term assets as of December 31, 2019. After certain adjustments and expenses of sale, the Company received net consideration from the sale of $45.2 million. Subsequent to finalizing the working capital adjustment during the fourth quarter of 2019 the gain recognized on the Equity Transaction amounted to $13.7 million and is reflected within discontinued operations. The transaction was consummated on August 16, 2019. Pioneer sold to the Buyer all of the assets and liabilities associated with its liquid-filled transformer and dry-type transformer manufacturing businesses within the Company’s T&D Solutions segment. Pioneer Power retained its switchgear manufacturing business within the T&D Solutions segment, as well as all of the operations associated with its Critical Power segment. For presentation within these statements, the Disposed Companies are being presented as discontinued operations for all periods presented. Presentation The accompanying audited consolidated financial statements of the Company have been prepared pursuant to the rules of the SEC and reflect the accounts of the Company as of December 31, 2019. Certain information and footnote disclosures, normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”), have been condensed or omitted pursuant to those rules and regulations. We believe that the disclosures made are adequate to make the information presented not misleading to the reader. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, necessary to fairly state the financial position, results of operations and cash flows with respect to the audited consolidated financial statements have been included. These audited consolidated financial statements include the accounts of Pioneer and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. Liquidity The accompanying financial statements have been prepared on a basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. At December 31, 2019, we had $8.2 million of cash and cash equivalents on hand, generated primarily from the completion of the Equity Transaction, and working capital of $10.1 million. We have historically met our cash needs through a combination of cash flows from operating activities and bank borrowings under our revolving credit facilities. Our cash requirements historically were generally for operating activities, debt repayment, capital improvements and acquisitions. As all outstanding amounts under our credit facilities have been paid in full with the proceeds from the Equity Transaction during the year ended December 31, 2019, we expect to meet our cash needs with our working capital and cash flows from our operating activities. We expect our cash requirements to be generally for operating activities and capital improvements. During the quarter ended September 30, 2019 the Company declared a cash dividend of approximately $12 million in the aggregate which was subsequently enjoined by ruling of the courts in connection with the litigation with Myers Power Products, Inc. As a result of the court order, the cash dividend was cancelled by the Company during the fourth quarter of 2019. However, the timing and amount of future dividends could require the Company to seek capital funding to support its ongoing operations as the Company’s historical credit arrangements were terminated in connection with the Equity Transaction. There are two appeals pending in the California Court of Appeals for the Second Appellate District in connection with the litigation with Myers Power Products, Inc., which includes an appeal of an order modifying a previously issued preliminary injunction and an order enjoining the Company to obtain and post a $12 million bond in connection with the modified preliminary injunction. While the Company intends to defend itself vigorously, due to the uncertainties of litigation, the Company can give no assurance that it will prevail on the appeals which could have an adverse impact on the Company’s financial position. These appeals are currently scheduled to be heard later in calendar year 2021, after the underlying case is likely to be heard and decided. See Note 13 for further discussion. Rounding All dollar amounts (except share and per share data) presented are stated in thousands of dollars, unless otherwise noted. Amounts may not foot due to rounding.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES General The preparation of consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. Reclassifications Certain reclassifications have been made in prior years’ financial statements to conform to the presentation used in the current year. These reclassifications have not resulted in any changes to the previously reported net income for any year. Use of Estimates The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The financial statements include estimates based on currently available information and management’s judgment as to the outcome of future conditions and circumstances. Significant estimates in these financial statements include allowance for doubtful accounts receivable, inventory provision, useful lives and impairment of long-lived assets, income tax provision, and goodwill impairment. Changes in the status of certain facts or circumstances could result in material changes to the estimates used in the preparation of the financial statements and actual results could differ from the estimates and assumptions. Revenue Recognition Revenue is recognized when (1) a , (2) , (3) , (4 . Cost of Goods Sold Cost of goods sold for the T&D Solutions and Critical Power segments primarily includes charges for materials, direct labor and related benefits, freight (inbound and outbound), direct supplies and tools, purchasing and receiving costs, inspection costs, internal transfer costs, warehousing costs and utilities related to production facilities and, where appropriate, an allocation of overhead. Cost of goods sold for Critical Power Solutions also includes indirect labor and infrastructure cost related to the provision of field services. Financial Instruments The Company’s financial instruments consist primarily of cash and cash equivalents, receivables, payables and debt instruments. The carrying values of these financial instruments approximate their respective fair values as they are either short - The carrying amount reported in the consolidated balance sheet for shares held in CleanSpark, Inc., which are accounted for in accordance with the adoption of ASU 2016-01, of $936 included within short term investment approximates fair value as the asset has a readily determinable market value and as such it is considered a Level 1 asset. The estimated fair value of the warrants held in CleanSpark, Inc. of approximately $531 is considered a Level 3 asset due to unobservable inputs. Cash and Cash Equivalents Cash and cash equivalents comprise cash on hand, demand deposits and investments with an original maturity at the date of purchase of three months or less. Accounts Receivable The Company accounts for trade receivables at original invoice amount less an estimate made for doubtful receivables based on a review of all outstanding amounts on a monthly basis. Management determines the allowance for doubtful accounts by regularly evaluating individual customer receivables and considering a customer's financial condition, credit history and current economic conditions. The Company writes off trade receivables when they are deemed uncollectible. The Company records recoveries of trade receivables previously written off when it receives them. Management considers the Company’s allowance for doubtful accounts, which was $77 and $123 as of December 31, 2019 and 2018, respectively, sufficient to cover any exposure to loss in its accounts receivable. Long-Lived Assets Depreciation and amortization for property, plant and equipment, and finite life intangible assets, is computed and included in cost of goods sold and in selling and administrative expense, as appropriate. Long-lived assets, consisting primarily of property, plant and equipment, are stated at cost less accumulated depreciation. Property, plant and equipment are depreciated using the straight line method, based on the estimated useful lives of the assets (buildings – 25 years, machinery and equipment - 5 to 15 years, computer hardware and software - 3 to 5 years, furniture & fixtures 5 to 7 years, leasehold improvements – term of lease). Depreciation commences in the year the assets are ready for their intended use. As a convention, in the initial year an asset is placed in service, the Company takes one half year of depreciation. Finite life intangible assets consist primarily of customer relationships in multiple categories that are specific to the businesses acquired and for which estimated useful lives were determined based on actual historical customer attrition rates. The Company’s other finite life intangible assets consist of non-compete agreements, which have defined terms, certain trademarks which the Company has elected to gradually discontinue, and internally-developed software. These finite life intangible assets are amortized by the Company over periods ranging from four to ten years. Long-lived assets and finite life intangible assets are reviewed for impairment whenever events or circumstances have occurred that indicate the remaining useful life of the asset may warrant revision or that the remaining balance of the asset may not be recoverable. Upon indications of impairment, or in the normal course of annual testing, assets and liabilities are grouped at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. The measurement of possible impairment is generally estimated by the ability to recover the balance of an asset group from its expected future operating cash flows on an undiscounted basis. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the asset exceeds the fair value thereof. Determining asset groups and underlying cash flows requires the use of significant judgment. Goodwill and Indefinite Life Intangible Assets Goodwill was generated through the acquisitions made by the Company between 2010 and 2015. As the total consideration paid exceeded the value of the net assets acquired, the Company recorded goodwill for each of the completed acquisitions. At the date of acquisition, the Company performed a valuation to determine the value of the intangible assets, and the allocation of the purchase price to the assets and liabilities acquired. The goodwill is attributable to synergies and economies of scale provided to us by the acquired entity. The Company tests its goodwill and indefinite-lived intangible asset for impairment at least annually (as of October 1) and whenever events or circumstances change that indicate impairment may have occurred. A significant amount of judgment is involved in determining if an indicator of impairment has occurred. Such indicators may include, among others: a significant decline in the Company’s expected future cash flows; a sustained, significant decline in the Company’s stock price and market capitalization; a significant adverse change in legal factors or in the business climate of its segments; unanticipated competition; and slower growth rates. Any adverse change in these factors could have a significant impact on the recoverability of goodwill, the indefinite-lived intangible assets and the Company’s consolidated financial results. As described in Note 11, the Company recorded impairment charges of $83 for intangible assets and $3.0 million against goodwill in 2019 and $870, $377 and $103 against technology-related industry accreditation, customer relationships and non-complete agreements, respectively, in 2018. The Company tests its goodwill for impairment at the reporting unit level, which is an operating segment or a segment that is one level below its operating segments. An operating segment is defined by ASC 280-10-50 as a component of an enterprise that earns revenue and incurs expenses, of which discrete financial information is available. The goodwill has been assigned to the reporting unit to which the value relates. Two of the Company’s four reporting units have goodwill. The Company tests goodwill by estimating the fair value of the reporting unit using a discounted cash flow model and other valuation techniques, but may elect to perform a qualitative analysis. A quantitative analysis is used to determine an estimated fair value representing the amount at which a reporting unit could be bought or sold in a current transaction between willing parties on an arms-length basis. The estimated fair value of each reporting unit is derived using a discounted cash flow method based on market and reporting unit-specific assumptions, including estimated future revenues and expenses, weighted average cost of capital, capital expenditures, the useful life over which cash flows will occur and other assumptions which are considered reasonable and inherent in discounted cash flow analysis. A qualitative analysis is performed by assessing certain trends and factors, including projected market outlook and growth rates, forecasted and actual sales and operating profit margins, discount rates, industry data and other relevant qualitative factors. These trends and factors are compared to, and based on, the assumptions used in the most recent quantitative assessment. As of December 31, 2019, the Company has written the value of all of its goodwill and intangible assets to zero because the Company determined they were impaired. Income Taxes The Company accounts for income taxes under the asset and liability method, based on the income tax laws and rates in the countries in which operations are conducted and income is earned. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax basis of assets and liabilities. Developing the provision for income taxes requires significant judgment and expertise in federal, international and state income tax laws, regulations and strategies, including the determination of deferred tax assets and liabilities and, if necessary, any valuation allowances that may be required for deferred tax assets. The Company records a valuation allowance to reduce its deferred tax assets to the amount that is more likely than not to be realized. The Company believes that the deferred tax asset recorded as of December 31, 2019 and 2018 is realizable through future reversals of existing taxable temporary differences and future taxable income. If the Company was to subsequently determine that it would be able to realize deferred tax assets in the future in excess of its net recorded amount, an adjustment to deferred tax assets would increase net income for the period in which such determination was made. The Company will continue to assess the adequacy of the valuation allowance on a quarterly basis. The Company’s tax filings are subject to audit by various taxing authorities. The objective of accounting for income taxes is to recognize the amount of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences or events that have been recognized in the Company’s financial statements or tax returns. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position (see “Unrecognized Tax Benefits” below). Income tax related interest and penalties are grouped with interest expense on the consolidated statement of operations. Unrecognized Tax Benefits The Company accounts for unrecognized tax benefits in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) “Income Taxes” (“ASC 740”). ASC 740 prescribes a recognition threshold that a tax position is required to meet before being recognized in the financial statements and provides guidance on de-recognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition issues. ASC 740 contains a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained upon ultimate settlement with a taxing authority, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. Additionally, ASC 740 requires the Company to accrue interest and related penalties, if applicable, on all tax positions for which reserves have been established consistent with jurisdictional tax laws. See Note 16 ‒ Income Taxes. Share-Based Payments The Company accounts for share based payments in accordance with the provisions of FASB ASC 718 “Compensation – Stock Compensation” and accordingly recognizes in its financial statements share based payments at their fair value. In addition, it recognizes in the financial statements an expense based on the grant date fair value of stock options granted to employees and directors. The expense is recognized on a straight line basis over the expected option life while taking into account the vesting period and the offsetting credit is recorded in additional paid-in capital. Upon exercise of options, the consideration paid together with the amount previously recorded as additional paid-in capital is recognized as capital stock. The Company estimates its forfeiture rate in order to determine its compensation expense arising from stock based awards. The Company uses the Black-Scholes Merton option pricing model to determine the fair value of the options. Non-employee members of the Board of Directors are deemed to be employees for the purposes of recognizing share-based compensation expense. Inventories Inventories are stated at the lower of cost or net realizable value using first-in, first-out (FIFO) or weighted-average methods and include the cost of materials, labor and manufacturing overhead. The Company uses estimates in determining the level of reserves required to state inventory at the lower of cost or market. The Company estimates are based on market activity levels, production requirements, the physical condition of products and technological innovation. Changes in any of these factors may result in adjustments to the carrying value of inventory. See Note 8 - Inventories. Income (Loss) Per Share Basic income (loss) per share is computed by dividing the income (loss) for the period by the weighted average number of common shares outstanding during the period. Diluted income (loss) per share is computed by dividing the income (loss) for the period by the weighted average number of common and common equivalent shares outstanding during the period. (See Note 18 ‒ Basic and Diluted Net Loss Per Share). Fair Value Measurements FASB ASC 820 “Fair Value Measurement and Disclosure” applies to all assets and liabilities that are being measured and reported on a fair value basis. ASC 820 establishes a framework for measuring fair value in U.S GAAP, and expands disclosure about fair value measurements. ASC 820 enables the reader of the financial statements to assess the inputs used to develop those measurements by establishing a hierarchy for ranking the quality and reliability of the information used to determine fair values. ASC 820 requires that assets and liabilities carried at fair value be classified and disclosed in one of the following three categories: Level 1: Quoted market prices in active markets for identical assets or liabilities. Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data. Level 3: Unobservable inputs that are not corroborated by market data. In determining the appropriate levels, the Company performs a detailed analysis of the assets and liabilities that are subject to ASC 820. At each reporting period, all assets and liabilities for which the fair value measurement is based on significant unobservable inputs are classified as Level 3. The fair value represents management’s best estimates based on a range of methodologies and assumptions. The carrying value of receivables and payables arising in the ordinary course of business approximate fair value because of the relatively short period of time between their origination and expected realization. The Company’s financial instruments consist primarily of cash and cash equivalents, receivables, notes receivable in connection with the Equity Transaction, payables and debt instruments. The carrying values of these financial instruments approximate their respective fair values as they are either short-term in nature or carry interest rates which are periodically adjusted to market rates. Unless otherwise indicated, the carrying value of these financial instruments approximates their fair market value. The carrying amount reported in the consolidated balance sheet for shares held in CleanSpark, Inc. of $936 included within short term investment approximates fair value as the asset has a readily determinable market value and as such it is considered a Level 1 asset. The estimated fair value of the warrants held in CleanSpark, Inc. of approximately $531 is considered a Level 3 asset due to unobservable inputs.

May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. Since then, the FASB has also issued ASU 2016-08, Revenue from Contracts with Customers Principals versus Agent Considerations, Revenue from Contracts with Customers Identifying Performance Obligations and Licensing Revenue Recognition Revenue from Contracts with Customers Leases Leases Amendments to SEC Paragraphs Pursuant to the Staff Announcement at the July 20, 2017 EITF Meeting and Recession of Prior SEC Staff Announcements and Observer Comments, In July 2015, the FASB approved a one-year deferral of the effective date to January 1, 2018, with early adoption to be permitted as of the original effective date of January 1, 2017. Once this standard becomes effective, companies may We completed a review of our various revenue streams within our two reportable segments, T&D Solutions and Critical Power. We have gathered data to quantify the amount of sales by type of revenue stream and categorized the types of sales for our business units for the purpose of comparing how we currently recognize revenue to the new standard in order to quantify the impact of this ASU. We have made policy elections within the amended standard that are consistent with our current accounting. We adopted ASU 2014-09 in our first quarter of 2018 using the modified retrospective approach. We have performed a quantitative assessment of adopting ASU 2014-09 and concluded that there was no material impact to our financial statements other than enhanced disclosures and no changes to the opening retained earnings.

DIVESTITURES	3. DIVESTITURES Pioneer Critical Power, Inc. On January 22, 2019, Pioneer Critical Power, Inc., a Delaware corporation (“PCPI”), a wholly-owned subsidiary of the Company within the T&D Solutions segment, CleanSpark and CleanSpark Acquisition, Inc., a Delaware corporation (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which, among other things, Merger Sub merged with and into PCPI, with PCPI becoming a wholly-owned subsidiary of the CleanSpark and the surviving company of the merger (the “Merger”). At the effective date of the Merger, all of the issued and outstanding shares of common stock of PCPI, par value $0.01 per share, were converted into the right to receive (i) 175,000 shares of common stock, par value $0.001 per share (“CleanSpark Common Stock”), of CleanSpark, (ii) a five-year warrant to purchase 50,000 shares of CleanSpark Common Stock at an exercise price of $16.00 per share, and (iii) a five-year warrant to purchase 50,000 shares of CleanSpark Common Stock at an exercise price of $20.00 per share. The Merger Agreement also contains representations, warranties and covenants of the parties customary for transactions similar to those entered into by the Merger Agreement. Such representations and warranties are made solely for purposes of the Merger Agreement and, in some cases, may be subject to qualifications and limitations agreed to by the parties in connection with the negotiated terms of the Merger Agreement and may have been qualified by disclosures that were made in connection with the parties’ entry into the Merger Agreement. The share quantities and exercise prices of warrants reflect the 10:1 stock split completed by CleanSpark in December 2019. In connection with the Merger Agreement, the Company, CleanSpark and PCPI entered into an Indemnity Agreement (the “Indemnity Agreement”), dated January 22, 2019, pursuant to which the Company agreed to assume the liabilities and obligations related to the claims made by Myers Powers Products, Inc. in the case titled Myers Power Products, Inc. v. Pioneer Power Solutions, Inc., Pioneer Custom Electrical Products, Corp., et al. In connection with entry into the Merger Agreement, the Company and CleanSpark entered into a Contract Manufacturing Agreement (the “Contract Manufacturing Agreement”), dated as of January 22, 2019, pursuant to which the Company will manufacture paralleling switchgear, automatic transfer switches and related control and circuit protective equipment (collectively, “Products”) exclusively for purchase by CleanSpark. CleanSpark will purchase the Products via purchase orders issued to the Company at any time and from time to time. The price for the Products payable by CleanSpark to the Company will be negotiated on a case by case basis, but all purchases of Products will have a target price of 91% of the CleanSpark customer’s purchase order price and will not be more than 109% of the Company’s cost. The Contract Manufacturing Agreement has a term of 18 months and may be extended by mutual agreement of the Company and CleanSpark. In connection with entry into the Merger Agreement, the Company and CleanSpark entered into a Non-Competition and Non-Solicitation Agreement (the “Non-Compete Agreement”), dated January 22, 2019, pursuant to which the Company agreed not to, among other things, own, manage, operate, finance, control, advise, render services to or guarantee the obligations of any person or entity that engages in or plans to engage in the design, manufacture, distribution and service of paralleling switchgear, automatic transfer switches, and related products (the “Restricted Business”). The Company agreed not to engage in the Restricted Business within any state or county within the United States in which CleanSpark or the surviving company of the Merger conducts such Restricted Business for a period of four (4) years from the date of the Non-Compete Agreement. In addition, the Company also agreed, for a period of four (4) years from the date of the Non-Compete Agreement, not to, among other things, directly or indirectly (i) solicit, induce, or attempt to induce customers, suppliers, licensees, licensors, franchisees, consultants of the Restricted Business as conducted by the Company, CleanSpark or the surviving company to cease doing business with the surviving company or CleanSpark or (ii) solicit, recruit, or encourage any of the surviving company’s or CleanSpark’s employees, or independent contractors to discontinue their employment or engagement with the surviving company or CleanSpark. The Merger resulted in the deconsolidation of PCPI and a gain of $4.2 million in the first quarter of 2019. The fair value of the investment in the common stock of CleanSpark was determined using quoted market prices and warrants were established using a Black Scholes model. From the date of sale through December 31, 2019, the estimated fair value of the warrants and CleanSpark common stock decreased to $1.4 million and an unrealized mark to market loss of $2.8 million was recognized within other expense for the period ended December 31, 2019. The PCPI entity was a dormant business unit at the time of this sale; therefore this sale has no impact to the discontinued operations presented within the financial statements. See Note 1 for details related to the sale of the Transformer business.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	4. FAIR VALUE MEASUREMENTS ASC 820, Fair Value Measurements and Disclosures ● Level 1 - inputs to the valuation methodology are quoted prices (unadjusted) for an identical asset or liability in an active market. ● Level 2 - inputs to the valuation methodology include quoted prices for a similar asset or liability in an active market or model derived valuations in which all significant inputs are observable for substantially the full term of the asset or liability. ● Level 3 - inputs to the valuation methodology are unobservable and significant to the fair value measurement of the asset or liability. At December 31, 2019, the Company’s financial instruments included the right to receive (i) 175,000 shares of common stock, par value $0.001 per share, of CleanSpark Common Stock, (ii) a five-year warrant to purchase 50,000 shares of CleanSpark Common Stock at an exercise price of $16.00 per share, and (iii) a five-year warrant to purchase 50,000 shares of CleanSpark Common Stock at an exercise price of $20.00 per share. The carrying amounts reported in the accompanying financial statements for cash and cash equivalents, receivables, inventories, accounts payable and accrued expenses and other current liabilities approximate their respective fair values because of the short-term nature of these accounts. The share quantities and exercise prices of warrants reflect the 10:1 stock split completed by CleanSpark in December 2019. The following table presents, for each of the fair value hierarchy levels required under ASC 820, the Company’s assets that are measured at fair value on a recurring basis: December 31, 2019 Quoted prices Significant Significant Assets Common shares $ 936 $ — $ — Warrants — — 531 Level 3 Valuation The warrant asset (which relates to warrants to purchase shares of common stock) is marked-to-market each reporting period with the change in fair value recorded to other income (expense) in the accompanying statements of operations until the warrants are exercised. The fair value of the warrant asset is estimated using a Black-Scholes option-pricing model. The significant assumptions used in preparing the option pricing model for valuing the warrant asset as of December 31, 2019, include (i) volatility of 282%, (ii) risk free interest rate of 1.66%, (iii) strike price ($16.00 and $20.00), (iv) fair value of common stock ($5.40), and (v) expected life of 4.07 years. The table presented below is a summary of changes in the fair value of the Company’s Level 3 valuation for the CleanSpark warrants for the year ended December 31, 2019: CleanSpark Balance at December 31, 2018 $ — Issuance of warrants 1,479 Change in fair value (948 ) Balance at December 31, 2019 $ 531 No other changes in valuation techniques or inputs occurred during the year ended December 31, 2019.

Revenue from Contract with Customer [Abstract]
REVENUES	5. Adoption of ASC Topic 606, “Revenue from Contracts with Customers” On January 1, 2018, we adopted Topic 606 using the modified retrospective method applied to those contracts which were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606. There was no adjustment to opening retained earnings due to the impact of adopting Topic 606. The Company adopted ASC 606 using the modified retrospective method. Nature of our products and services Our principal products and services include custom-engineered engine-generator sets and controls, complemented by a national field-service network to maintain and repair power generation assets. Products We provide switchgear that helps customers effectively and efficiently manage their electrical power distribution systems to desired specifications. Services Power generation systems represent considerable investments that require proper maintenance and service in order to operate reliably during a time of emergency. Our power maintenance programs provide preventative maintenance, repair and support service for our customers’ power generation systems. Our principal source of revenue is derived from sales of products and fees for services. We measure revenue based upon the consideration specified in the customer arrangement, and revenue is recognized when the performance obligations in the customer arrangement are satisfied. A performance obligation is a promise in a contract to transfer a distinct product or service to the customer. The transaction price of a contract is allocated to each distinct performance obligation and recognized as revenue when or as, the customer receives the benefit of the performance obligation. Customers typically receive the benefit of our products when the risk of loss or control for the product transfers to the customer and for services as they are performed. Under ASC 606, revenue is recognized when a customer obtains control of promised products or services in an amount that reflects the consideration we expect to receive in exchange for those products or services. To achieve this core principal, the Company applies the following five steps: 1) Identify the contract with a customer A contract with a customer exists when (i) the Company enters into an enforceable contract with a customer that defines each party’s rights regarding the products or services to be transferred and identifies the payment terms related to these products or services, (ii) the contract has commercial substance and, (iii) the Company determines that collection of substantially all consideration for products or services that are transferred is probable based on the customer’s intent and ability to pay the promised consideration. The Company applies judgment in determining the customer’s ability and intention to pay, which is based on a variety of factors including the customer’s historical payment experience or, in the case of a new customer, published credit and financial information pertaining to the customer. 2) Identify the performance obligations in the contract Performance obligations promised in a contract are identified based on the products or services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the product or service either on its own or together with other resources that are readily available from third parties or from the Company, and are distinct in the context of the contract, whereby the transfer of the products or services is separately identifiable from other promises in the contract. To the extent a contract includes multiple promised products or services, the Company must apply judgment to determine whether promised products or services are capable of being distinct and distinct in the context of the contract. If these criteria are not met the promised products or services are accounted for as a combined performance obligation. 3) Determine the transaction price The transaction price is determined based on the consideration to which the Company will be entitled in exchange for transferring products or services to the customer. The customer payments are generally due in 30 days. 4) Allocate the transaction price to performance obligations in the contract If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price basis or cost of the product or service. The Company determines standalone selling price based on the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, the Company estimates the standalone selling price taking into account available information such as market conditions and internally approved pricing guidelines related to the performance obligations. 5) Recognize revenue when or as the Company satisfies a performance obligation The Company satisfies performance obligations either over time or at a point in time. Revenue is recognized at the time the related performance obligation is satisfied by transferring a promised product or service to a customer. Substantially all of our revenue from the sale of switchgear and power generation equipment is recognized at a point of time. Revenues are recognized at the point in time that the customer obtains control of the good which is when it has taken title to the products and has assumed the risks and rewards of ownership specified in the purchase order or sales agreement. Service revenues include maintenance contracts that are recognized over time based on the contract term and repair services which are recognized as services are delivered. The following table presents our revenues disaggregated by revenue discipline: For the Year Ended December 31, 2019 2018 Products $ 10,401 $ 10,327 Services 10,181 9,800 Total Revenue $ 20,582 $ 20,127 See Note 17 – Business Segment, Geographic and Customer Information

Discontinued Operations and Disposal Groups [Abstract]
DISCONTINUED OPERATIONS	7. DISCONTINUED OPERATIONS A discontinued operation is a component of the Company’s business that represents a separate major line of business that had been disposed of or is held for sale. Classification as a discontinued operation occurs upon disposal or when the operation meets the criteria to be classified as held for sale, if earlier. When an operation is classified as a discontinued operation, the comparative Consolidated Statement of Operations, Consolidated Statement of Cash Flows, and Consolidated Balance Sheets are presented as if the operation had been discontinued from the start of the comparative year. Based upon the authoritative guidance, the Company concluded that the operations of the liquid-filled and dry-type transformer business should be presented as discontinued operations as of December 31, 2019. Overview On August 16, 2019, the Company completed the Equity Transaction pursuant to the Stock Purchase Agreement, by and among the Company, the Disposed Companies, Nathan Mazurek, and the Buyer. Pursuant to the terms of the Stock Purchase Agreement, the Company sold (i) all of the issued and outstanding equity interests of Electrogroup to the Canadian Buyer and (ii) all of the issued and outstanding equity interests of Jefferson and JE Mexico to the US Buyer. Upon completion of the Equity Transaction, Pioneer Power sold to the Buyer all of the assets and liabilities associated with its liquid-filled transformer and dry-type transformer manufacturing businesses within the Company’s T&D Segment. Pioneer Power retained its switchgear manufacturing business within the T&D Solutions segment, as well as all of the operations associated with its Critical Power segment. Consideration The consideration paid by the Buyer in the Equity Transaction is a base cash purchase price of $60.5 million, as well as the issuance by the Buyer of two subordinated promissory notes to Pioneer Power in the principal amounts of $5.0 million and $2.5 million, for a total aggregate principal amount of $7.5 million (the “Seller Notes”), in each case subject to adjustment pursuant to the terms of the Stock Purchase Agreement. Pursuant to the terms of the Stock Purchase Agreement, the Seller Notes will bear interest at an annualized rate of 4.0%, to be paid-in-kind annually, and will have a maturity date of December 31, 2022. In addition, pursuant to the terms of the Stock Purchase Agreement, as amended, the Buyer may set-off on a dollar-for-dollar basis any indemnifiable losses the Buyer suffers as a result of certain actions or omissions by Pioneer Power or the Disposed Companies against the first Seller Note in the aggregate principal amount of $5.0 million, and such right of set-off is the Buyer’s sole source of recovery with respect to losses resulting from inaccuracies or breaches of the Company’s representations and warranties, except for breaches of certain fundamental warranties, claims of fraud and breaches of representations, warranties or covenants relating to taxes, and claims for certain specific indemnities. No such losses are expected as of December 31, 2019. During the fourth quarter of 2019, the Company and the Buyer, pursuant to the Stock Purchase Agreement, completed the net working capital adjustment, which resulted in the Company paying the Buyer $1.7 million in cash and reducing the principal amount of the $5.0 million Seller Note to $3.3 million. The Company has revalued the notes for an appropriate imputed interest rate, resulting in a reduction to the value of the notes at December 31, 2019 of $651, for a carrying value of $5.1 million, which is included within other long term assets as of December 31, 2019. After certain adjustments and expenses of sale, the Company received net consideration from the sale of $45.2 million. Subsequent to finalizing the working capital adjustment during the fourth quarter of 2019 the gain recognized on the Equity Transaction amounted to $13.7 million and is reflected within discontinued operations. Covenants In addition, pursuant to the Stock Purchase Agreement, each of Pioneer Power, its affiliates and Nathan Mazurek, Pioneer Power’s President, Chief Executive Officer and Chairman of the Board of Directors, have agreed to a non-solicitation provision that generally prohibits such persons, for a three-year period, from, among other things, soliciting or attempting to hire employees of the Disposed Companies or the Buyer or engaging in the business operated by the Disposed Companies within certain geographic areas, subject to certain limitations and exceptions. Indemnification Pursuant to the Stock Purchase Agreement, Pioneer Power and the Buyer have each agreed to indemnify one another for any and all liabilities, losses, damages, claims, demands, suits, actions, judgments, fines, penalties, deficiencies, awards, taxes, assessments, costs or expenses (including reasonable attorney’s or other professional fees and expenses) (“Losses”) resulting from any inaccuracy or breach of the respective party’s representations and warranties or any breach or nonperformance of the respective party’s covenants and agreements in the Stock Purchase Agreement or its related ancillary agreements. In addition, Pioneer Power has agreed to indemnify the Buyer and its affiliated parties for Losses resulting from, among other things, certain pre-closing tax matters, debt held by the Disposed Companies, transaction expenses, breaches of representations and warranties that are not covered by the Buyer’s representation and warranty insurance because the Buyer had knowledge of such breach (only to the extent such Losses would have been covered by the representation and warranty insurance had the Buyer not known of such breach) (“Interim Breaches”), certain matters related to Electrogroup’s operations, certain legal proceedings, certain matters related to Nexus Custom Magnetics, L.L.C., a wholly owned subsidiary of Jefferson, and certain matters concerning end-user software utilized by the Disposed Companies. The indemnification obligations of Pioneer Power with respect to Losses of the Buyer resulting from inaccuracies or breaches of the Company’s representations and warranties, except for breaches of certain fundamental warranties, claims of fraud and breaches of representations, warranties or covenants relating to taxes, and claims for certain specific indemnities, are subject to (i) a true deductible equal to $330,000, (ii) a cap equal to $330,000, and (iii) a per-claim threshold amount of $50,000, and any such Losses shall be satisfied solely through a set-off to the first Seller Note with the principal amount of $3.3 million. In addition, the indemnification rights of the Buyer with respect to Interim Breaches are subject to a cap equal to $5.0 million, and the indemnification rights of the Buyer with respect to Losses resulting from certain legal matters are subject to a true deductible equal to $150,000 and a cap equal to $3.3 million. The indemnification obligations of the Buyer, except with respect to breaches of certain fundamental representations and warranties and claims of fraud, are subject to a true deductible equal to $330,000 and a cap equal to $3.3 million. In addition, each party’s total indemnification obligation is subject to a cap equal to the purchase price, except for claims of fraud. The Buyer has obtained a customary representation and warranty insurance policy insuring the Buyer against losses resulting from a breach of representations and warranties by Pioneer Power and the Disposed Companies, and the Buyer is required to use commercially reasonable efforts to utilize the representation and warranty insurance to cover any Losses resulting from such a breach. Other Provisions The Stock Purchase Agreement also contains customary representations and warranties, and provisions governing certain other matters between the parties. Operating results of the liquid-filled and dry-type transformer manufacturing businesses previously included in the T&D Solutions segment, have now been reclassified as discontinued operations for all periods presented. The components of assets and liabilities that are attributable to discontinued operations are as follows (in thousands): December 31, December 31, 2019 2018 Assets of discontinued operations: Accounts receivable - trade, net $ — $ 12,944 Inventories, net — 23,632 Income taxes receivable — 566 Prepaid expenses — 514 Property, plant and equipment, net — 4,406 Right of use asset — 2,124 Deferred income taxes — 134 Intangible assets, net — 3,460 Goodwill — 5,557 Assets of discontinued operations $ — $ 53,337 Liabilities of discontinued operations: Bank overdrafts $ — $ 1,690 Accounts payable and accrued liabilities — 18,894 Income taxes payable — 778 Pension deficit — 148 Other long-term liabilities — 2,187 Liabilities of discontinued operations $ — $ 23,697 During the quarter ended June 30, 2019 the Company’s Reynosa Facility was damaged by a flood resulting in damages to inventory. This loss has been partially offset by $2.4 million of insurance proceeds that the Company expects to receive. The Company received $600 of these insurance proceeds during the year ended December 31, 2019, and $1.4 million of these insurance proceeds were received subsequent to year-end. While the net loss on inventory damaged amounting to approximately $782 has been reflected within the Cost of goods sold in discontinued operations, the corresponding insurance receivable of $1.8 million has been recognized as an asset from continuing operations as of December 31, 2019. The amount of damaged inventory and insurance proceeds are based upon management’s best estimate, and the actual amount of damaged inventory and insurance proceeds may differ from such estimates. During the year ended December 31, 2019, the Company determined that there was substantial doubt over our ability to collect $2.3 million due from our former Asian manufacturing partner as the Company no longer retains a relationship with this entity subsequent to the sale of the Transformer business. While the Company will continue to pursue collection of the amount, based upon discussions with the supplier during the year ended December 31, 2019, the recognition of a reserve was deemed appropriate.

Other Assets [Abstract]
OTHER ASSETS	10. OTHER ASSETS Included in other assets at December 31, 2019 and December 31, 2018 are right-of-use assets, net, of $1.8 million and $2.2 million, respectively, related to our lease obligations. In December 2011 and January 2012, the Company made two secured loans, each in the amount of $300 to a developer of a renewable energy project in the U.S, secured by assets of the developer. The promissory notes accrue interest at a rate of 4.5% per annum with a final payment of all unpaid principal and interest becoming fully due and payable upon the earlier to occur of (i) the four year anniversary of the issuance date of the promissory notes, or (ii) an event of default. As defined in the promissory notes, an event of default includes, but is not limited to, the following: any bankruptcy, reorganization or similar proceeding involving the borrower, a sale or transfer of substantially all the assets of the borrower, a default by the borrower relating to any indebtedness due to third parties, the incurrence of additional indebtedness by the borrower without the Company’s written consent and failure of the borrower to perform its obligations pursuant to its other agreements with the Company, including its purchase order for pad mount transformers. The Company has determined that the probability of recovering the secured loans is unlikely, and has written-off the balance of $600 during the year ended December 31, 2019. As a result of the Company entering into the Stock Purchase Agreement on June 28, 2019, as amended (see Note 3 – Divestitures), we have received two subordinated promissory notes in the aggregate principal amount of $7.5 million, subject to certain adjustments. The subordinated promissory notes accrue interests at a rate of 4.0% per annum with a final payment of all unpaid principal and interest becoming fully due and payable at December 31, 2022. The Company determined the fair value of the notes based on market conditions and prevailing interest rates. During the fourth quarter of 2019, the Company and the Buyer, pursuant to the Stock Purchase Agreement, completed the net working capital adjustment, which resulted in the Company paying the Buyer $1.7 million in cash and reducing the principal amount of the $5.0 million Seller Note to $3.3 million. The Company has revalued the notes for an appropriate imputed interest rate, resulting in a reduction to the value of the notes at December 31, 2019 of $651, for a carrying value of $5.1 million.

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND OTHER INTANGIBLE ASSETS	11. GOODWILL AND OTHER INTANGIBLE ASSETS Goodwill is tested at the reporting unit level annually and if necessary, whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. In 2018, the Company determined certain definite lived intangible assets within the switchgear reporting unit had carrying values that exceeded its fair value. As a result, the Company recorded impairment charges of $870, $377 and $103 against technology-related industry accreditation, customer relationships and non-complete agreements, respectively. During 2019, the Company recorded impairment charges of $83 against internally developed software during 2019 in its Critical Power segment. Prior to 2017, the Company tested goodwill for impairment using a quantitative analysis consisting of a two-step approach. The first step of our quantitative analysis consisted of a comparison of the carrying value of our reporting units, including goodwill, to the estimated fair value of our reporting units using a discounted cash flow methodology. If step one results in the carrying value of the reporting unit exceeding the fair value of such reporting unit, we would then proceed to step two which would require us to calculate the amount of impairment loss, if any, that we would record for such reporting unit. In the fourth quarter of 2017 the Company adopted ASU No. 2017-04, “Simplifying the Test for Goodwill Impairment” and eliminated Step 2 from the goodwill impairment test. The goodwill impairment test was performed as of October 1, 2019 and involves significant estimates. The Company recorded an impairment charge of $3.0 million to the remaining goodwill at the TESI business unit in 2019, based in part by the loss of the Verizon agreement, which is recorded in continuing operations within selling, general, and administrative expense. The Company recorded no impairment to goodwill during the year ended December 31, 2018. Changes in the carrying amount of goodwill by reportable segment during the years ended December 31, 2019 and 2018 are as follows: Critical Total Gross Goodwill: Balance as of January 1, 2018 $ 2,969 $ 2,969 No activity — — Balance as of December 31, 2018 $ 2,969 $ 2,969 Accumulated impairment losses: Balance as of January 1, 2018 $ — $ — Impairment charges — — Balance as of December 31, 2018 $ — $ — Net Goodwill $ 2,969 $ 2,969 Gross Goodwill: Balance as of January 1, 2019 $ 2,969 $ 2,969 No activity — — Balance as of December 31, 2019 $ 2,969 $ 2,969 Accumulated impairment losses: Balance as of January 1, 2019 $ — $ — Impairment charges (2,969 ) (2,969 ) Balance as of December 31, 2019 $ (2,969 ) $ (2,969 ) Net Goodwill $ — $ — Changes in intangible asset balances for the years ended December 31, 2019 and 2018 consisted of the following: Critical Power Total Solutions Intangible Segment Assets Balance as of January 1, 2018 $ 1,245 $ 1,245 Amortization (1,121 ) (1,121 ) Foreign currency translation — — Balance as of December 31, 2018 $ 124 $ 124 Amortization (41 ) (41 ) Impairment charges (83 ) (83 ) Foreign currency translation — — Balance as of December 31, 2019 $ — $ — The components of intangible assets at December 31, 2019 are summarized below: Weighted Average Amortization Years Gross Carrying Amount Accumulated Amortization Impairment Charges Foreign Currency Translation Net Book Value Internally developed software 7 289 (206 ) (83 ) — — Total intangible assets $ 289 $ (206 ) $ (83 ) $ — $ — (a) During 2019, The components of intangible assets at December 31, 2018 are summarized below: Weighted Average Amortization Years Gross Carrying Amount Accumulated Amortization Impairment Charges Foreign Currency Translation Net Book Value Customer relationships 7 (b) $ 7,202 $ (6,175 ) $ (377 ) $ — $ 650 Non-compete agreements 4 (b) 705 (587 ) (103 ) — 15 Trademarks Indefinite 1,816 — — — 1,816 Internally developed software 7 289 (165 ) — — 124 Developed technology 10 492 (197 ) — — 295 Technology-related industry accreditations Indefinite (b) 1,576 — (870 ) (22 ) 684 Total intangible assets $ 12,080 $ (7,124 ) $ (1,350 ) $ (22 ) $ 3,584 (b) During 2018,

On January 11, 2016, Myers Power Products, Inc., a specialty electrical products manufacturer, filed suit with the Superior Court of the State of California, County of Los Angeles, against us, PCEP and two PCEP employees who are former employees of Myers Power Products, Inc., Geo Murickan, the president of PCEP (“Murickan”), and Brett DeChellis (“DeChellis”), alleging, among other things, that Murickan wrongly used and retained confidential business information of Myers Power Products, Inc. for the benefit of us and PCEP, in breach of their confidentiality agreement and/or employment agreement entered into with Myers Power Products, Inc., and that we and PCEP knowingly received and used such confidential business information. Myers Power Products, Inc. is seeking injunctive relief enjoining us, PCEP and our employees from using its confidential business information and compensatory damages of an unspecified unlimited amount (exceeding $25,000); however, the Company has recognized approximately $1.2 million for expected costs related to this litigation. On March 18, 2016, we filed an answer to the complaint, denying generally each and every allegation and relief sought by Myers Power Products, Inc. and seeking dismissal based on, among other things, failure to state facts sufficient to constitute a cause of action. We intend to contest the matter vigorously. Due to the uncertainties of litigation, however, we can give no assurance that we, PCEP and our employees will prevail on any claims made against us, PCEP and our employees in any such lawsuit. As of the filing of this report, this action is scheduled for trial in the second quarter of 2020. Also, we can give no assurance that any other lawsuits or claims brought in the future will not have an adverse effect on our financial condition, liquidity or operating results. We cannot execute the sale of PCEP until the lawsuit has been resolved. On October 4, 2019, the dividend that was payable by the Company was enjoined by court order of the Superior Court of California related to the foregoing case. The Company continues to contest the order. As of the date of this filing, this court order remains in place. On October 16, 2019, Myers Power Products, Inc. filed an ex parte application arguing the Company had violated, or intended to violate the modified preliminary injunction and sought order from the court for the Company to post a bond in an amount of $20,000 or more. The court has not taken any action on this request and the Company intends to vigorously defend its rights in the event the order is granted. There are also two appeals pending in the California Court of Appeals for the Second Appellate District, which includes an appeal of an order modifying a previously issued preliminary injunction and an order enjoining us to obtain and post a $12 million bond in connection with the modified preliminary injunction. Due to the uncertainties of litigation, the Company can give no assurance that it will prevail on the appeals. These appeals are currently scheduled to be heard later in calendar year 2021, after the underlying case is likely to be heard and decided. With respect to all such lawsuits, claims and proceedings, the Company records a reserve when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. However, the outcomes of any currently pending lawsuits, claims and proceedings cannot be predicted, and therefore, there can be no assurance that this will be the case.

Share-based Payment Arrangement [Abstract]
STOCK-BASED COMPENSATION	15. STOCK-BASED COMPENSATION On December 2, 2009, the Company adopted the 2009 Equity Incentive Plan (the “2009 Plan”) for the purpose of issuing incentive stock options intended to qualify under Section 422 of the Internal Revenue Code of 1986, as amended, non-qualified stock options, restricted stock, stock appreciation rights, performance unit awards and stock bonus awards to employees, directors, consultants and other service providers. A total of 320,000 shares of common stock are reserved for issuance under the 2009 Plan. Options may be granted under the 2009 Plan on terms and at prices as determined by the board of directors or by the plan administrators appointed by the board of directors. On May 11, 2011, the board of directors of the Company adopted the Pioneer Power Solutions, Inc. 2011 Long-Term Incentive Plan (the “2011 Plan”) which was subsequently approved by stockholders of the Company on May 31, 2011. The 2011 Plan replaces and supersedes the 2009 Plan. The Company’s outside directors and employees, including the Company’s principal executive officer, principal financial officer and other named executive officers, and certain contractors are all eligible to participate in the 2011 Plan. The 2011 Plan allows for the granting of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock, restricted stock units, performance awards, dividend equivalent rights, and other awards, which may be granted singly, in combination, or in tandem, and upon such terms as are determined by the Board or a committee of the Board that is designated to administer the Plan. Subject to certain adjustments, the maximum number of shares of the Company’s common stock that may be delivered pursuant to awards under the 2011 Plan is 700,000 shares. As of December 31, 2019, 379,800 stock options had been granted and are considered outstanding, consisting of 21,000 incentive stock options and 358,800 non-qualified stock options. Expense for stock-based compensation recorded for the years ended December 31, 2019 and 2018 was approximately $12 and $165, respectively. All of the stock-based compensation expense is included in selling, general and administrative expenses in the accompanying consolidated statements of operations. As of December 31, 2019, the Company had total stock-based compensation expense remaining to be recognized of approximately $2. The fair value of the stock options granted was measured using the Black-Scholes valuation model with the following assumptions: Year Ended December 31, 2019 2018 Expected volatility — 29 % Expected life in years — 5.5 Risk-free interest rate — 3 % Dividend yield — 0 % A summary of stock option activity for the years ended December 31, 2019 and 2018, and changes during the years then ended is presented below: Stock Weighted average Weighted Aggregate Outstanding as of January 1, 2018 435,800 $ 8.35 7.50 $ 216 Granted 7,000 5.60 — — Exercised — — Forfeited (18,000 ) 8.54 — Outstanding as of January 1, 2019 424,800 $ 8.30 6.50 $ 22 Granted — — Exercised — — Forfeited (45,000 ) 14.75 Outstanding as of December 31, 2019 379,800 $ 7.54 6.10 $ — Exercisable as of December 31, 2019 376,467 $ 7.54 6.10 $ — The total number of shares reserved for the plan is 700,000 leaving a balance of 293,867 available for future grants. Intrinsic value is the difference between the market value of the stock at December 31, 2019 and the exercise price which is aggregated for all options outstanding and exercisable.

The increase in the Company’s effective tax rate during 2019 primarily reflects the impact of the sale of its transformers business, the recognition of a valuation allowance and the utilization of its net operating losses. The net deferred income tax asset was comprised of the following: December 31, 2019 2018 Noncurrent deferred income taxes Total assets $ 844 $ 2,837 Total liabilities (844 ) (1,592 ) Net noncurrent deferred income tax asset — 1,245 Net deferred income tax asset $ — $ 1,245 The tax effect of temporary differences between GAAP accounting and federal income tax accounting creating deferred income tax assets and liabilities were as follows: December 31, 2019 2018 Deferred tax assets U.S. net operating loss carry forward $ — $ 662 Non-deductible reserves 1,785 1,628 Tax credits 4,631 4,631 Intangibles 2,189 1,634 Other — 442 Valuation allowance (7,761 ) (6,160 ) Net deferred tax assets 844 2,837 Deferred tax liabilities Fixed assets (64 ) (313 ) Intangibles — (723 ) Other (780 ) (556 ) Net deferred tax liabilities (844 ) (1,592 ) Deferred asset, net $ — $ 1,245 The assessment of the amount of value assigned to our deferred tax assets under the applicable accounting rules is judgmental. We are required to consider all available positive and negative evidence in evaluating the likelihood that we will be able to realize the benefit of our deferred tax assets in the future. Such evidence includes scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and the results of recent operations. Since this evaluation requires consideration of events that may occur some years into the future, there is an element of judgment involved. Realization of our deferred tax assets is dependent on generating sufficient taxable income in future periods. We do not believe that it is more likely than not that future taxable income will be sufficient to allow us to recover any of the value assigned to our deferred tax assets. Accordingly, we have provided for a valuation allowance of the Company's foreign tax credits as we do not anticipate generating sufficient foreign source income. In addition, we have provided for a full valuation allowance on the domestic deferred tax assets as the combined effect of future domestic source income and the future reversals of future tax assets and liabilities will likely be insufficient to realize the full benefits of the assets. As of December 31, 2019, the Company has no net operating loss carryforward. The company has approximately $4.6 million of foreign tax credits for which it has provided a full valuation allowance and $39 of research and development credits which expire in 2032. A reconciliation of the beginning and ending amount of gross unrecognized tax benefits, exclusive of interest and penalties, is as follows: Uncertain Tax Position Balance as of January 1, 2018 $ 218 Increases due to changes in foreign exchange 224 Balance as of December 31, 2018 $ 442 Decreases related to tax returns becoming statuted barred during the year — Balance as of December 31, 2019 $ 442 The Company’s policy is to recognize interest and penalties related to income tax matters as interest expense. Interest and penalties as they relate to the payroll tax issue are recorded as other expense. Management believes that an adequate provision has been made for any adjustments that may result from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner not consistent with management’s expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs. Although timing of the resolution and/or closure of audits is highly uncertain, the Company does not believe it is reasonably possible that its unrecognized tax benefits would materially change in the next twelve months. The tax years subject to examination by major tax jurisdiction include the years 2013 and forward by the U.S. Internal Revenue Service and most state jurisdictions, and the years 2014 and forward for the Canadian jurisdiction.

BUSINESS SEGMENT, GEOGRAPHIC AND CUSTOMER INFORMATION	17. BUSINESS SEGMENT, GEOGRAPHIC AND CUSTOMER INFORMATION The Company follows ASC 280 - Segment Reporting in determining its reportable segments. The Company considered the way its management team, most notably its chief operating decision maker, makes operating decisions and assesses performance and considered which components of the Company’s enterprise have discrete financial information available. As the Company makes decisions using a manufactured products vs. distributed products and services group focus, its analysis resulted in two reportable segments: T&D Solutions and Critical Power. The Critical Power reportable segment is the Company’s Titan Energy Systems Inc. business unit. The T&D Solutions reportable segment is an aggregation of all other Company subsidiaries, together with sales and expenses attributable to strategic sales group for its T&D Solutions marketing activities. The T&D Solutions segment is involved in the design, manufacture and distribution of switchgear used primarily by large industrial and commercial operations to manage their electrical power distribution needs.

SUBSEQUENT EVENTS During the quarter ending March 31, 2020, the Company was notified by Verizon that it will not be renewing its contract with the Company for the period of April 1, 2020 through March 31, 2021. During the quarter ending March 31, 2020, the Company received $1.4 million of the insurance proceeds due from the June 2019 flood at the Company’s facility in Reynosa, Mexico. On January 30, 2020, the World Health Organization (“WHO”) announced a global health emergency because of a new strain of coronavirus originating in Wuhan, China (the “COVID-19 outbreak”) and the risks to the international community as the virus spreads globally beyond its point of origin. In March 2020, the WHO classified the COVID-19 outbreak as a pandemic, based on the rapid increase in exposure globally. The full impact of the COVID-19 outbreak continues to evolve as the date of this report. As such, it is uncertain as to the full magnitude that the pandemic will have on the Company’s financial condition, liquidity, and future results of operations. Management is actively monitoring the global situation on its financial condition, liquidity, operations, suppliers, industry, and workforce. Given the daily evolution of the COVID-19 outbreak and the global responses to curb its spread, the Company is not able to estimate the effects of the COVID-19 outbreak at this time, however if the pandemic continues it may have an adverse effect on the Company’s results of operations, financial condition, or liquidity for fiscal year 2020.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.
Reclassifications	Reclassifications Certain reclassifications have been made in prior years’ financial statements to conform to the presentation used in the current year. These reclassifications have not resulted in any changes to the previously reported net income for any year.
Use of Estimates	Use of Estimates The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The financial statements include estimates based on currently available information and management’s judgment as to the outcome of future conditions and circumstances. Significant estimates in these financial statements include allowance for doubtful accounts receivable, inventory provision, useful lives and impairment of long-lived assets, income tax provision, and goodwill impairment. Changes in the status of certain facts or circumstances could result in material changes to the estimates used in the preparation of the financial statements and actual results could differ from the estimates and assumptions.
Revenue Recognition	Revenue Recognition Revenue is recognized when (1) a , (2) , (3) , (4 .
Cost of Goods Sold	Cost of Goods Sold Cost of goods sold for the T&D Solutions and Critical Power segments primarily includes charges for materials, direct labor and related benefits, freight (inbound and outbound), direct supplies and tools, purchasing and receiving costs, inspection costs, internal transfer costs, warehousing costs and utilities related to production facilities and, where appropriate, an allocation of overhead. Cost of goods sold for Critical Power Solutions also includes indirect labor and infrastructure cost related to the provision of field services.
Financial Instruments	Financial Instruments The Company’s financial instruments consist primarily of cash and cash equivalents, receivables, payables and debt instruments. The carrying values of these financial instruments approximate their respective fair values as they are either short - The carrying amount reported in the consolidated balance sheet for shares held in CleanSpark, Inc., which are accounted for in accordance with the adoption of ASU 2016-01, of $936 included within short term investment approximates fair value as the asset has a readily determinable market value and as such it is considered a Level 1 asset. The estimated fair value of the warrants held in CleanSpark, Inc. of approximately $531 is considered a Level 3 asset due to unobservable inputs.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents comprise cash on hand, demand deposits and investments with an original maturity at the date of purchase of three months or less.
Accounts Receivable	Accounts Receivable The Company accounts for trade receivables at original invoice amount less an estimate made for doubtful receivables based on a review of all outstanding amounts on a monthly basis. Management determines the allowance for doubtful accounts by regularly evaluating individual customer receivables and considering a customer's financial condition, credit history and current economic conditions. The Company writes off trade receivables when they are deemed uncollectible. The Company records recoveries of trade receivables previously written off when it receives them. Management considers the Company’s allowance for doubtful accounts, which was $77 and $123 as of December 31, 2019 and 2018, respectively, sufficient to cover any exposure to loss in its accounts receivable.
Long-Lived Assets	Long-Lived Assets Depreciation and amortization for property, plant and equipment, and finite life intangible assets, is computed and included in cost of goods sold and in selling and administrative expense, as appropriate. Long-lived assets, consisting primarily of property, plant and equipment, are stated at cost less accumulated depreciation. Property, plant and equipment are depreciated using the straight line method, based on the estimated useful lives of the assets (buildings – 25 years, machinery and equipment - 5 to 15 years, computer hardware and software - 3 to 5 years, furniture & fixtures 5 to 7 years, leasehold improvements – term of lease). Depreciation commences in the year the assets are ready for their intended use. As a convention, in the initial year an asset is placed in service, the Company takes one half year of depreciation. Finite life intangible assets consist primarily of customer relationships in multiple categories that are specific to the businesses acquired and for which estimated useful lives were determined based on actual historical customer attrition rates. The Company’s other finite life intangible assets consist of non-compete agreements, which have defined terms, certain trademarks which the Company has elected to gradually discontinue, and internally-developed software. These finite life intangible assets are amortized by the Company over periods ranging from four to ten years. Long-lived assets and finite life intangible assets are reviewed for impairment whenever events or circumstances have occurred that indicate the remaining useful life of the asset may warrant revision or that the remaining balance of the asset may not be recoverable. Upon indications of impairment, or in the normal course of annual testing, assets and liabilities are grouped at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. The measurement of possible impairment is generally estimated by the ability to recover the balance of an asset group from its expected future operating cash flows on an undiscounted basis. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the asset exceeds the fair value thereof. Determining asset groups and underlying cash flows requires the use of significant judgment.
Goodwill and Indefinite Life Intangible Assets	Goodwill and Indefinite Life Intangible Assets Goodwill was generated through the acquisitions made by the Company between 2010 and 2015. As the total consideration paid exceeded the value of the net assets acquired, the Company recorded goodwill for each of the completed acquisitions. At the date of acquisition, the Company performed a valuation to determine the value of the intangible assets, and the allocation of the purchase price to the assets and liabilities acquired. The goodwill is attributable to synergies and economies of scale provided to us by the acquired entity. The Company tests its goodwill and indefinite-lived intangible asset for impairment at least annually (as of October 1) and whenever events or circumstances change that indicate impairment may have occurred. A significant amount of judgment is involved in determining if an indicator of impairment has occurred. Such indicators may include, among others: a significant decline in the Company’s expected future cash flows; a sustained, significant decline in the Company’s stock price and market capitalization; a significant adverse change in legal factors or in the business climate of its segments; unanticipated competition; and slower growth rates. Any adverse change in these factors could have a significant impact on the recoverability of goodwill, the indefinite-lived intangible assets and the Company’s consolidated financial results. As described in Note 11, the Company recorded impairment charges of $83 for intangible assets and $3.0 million against goodwill in 2019 and $870, $377 and $103 against technology-related industry accreditation, customer relationships and non-complete agreements, respectively, in 2018. The Company tests its goodwill for impairment at the reporting unit level, which is an operating segment or a segment that is one level below its operating segments. An operating segment is defined by ASC 280-10-50 as a component of an enterprise that earns revenue and incurs expenses, of which discrete financial information is available. The goodwill has been assigned to the reporting unit to which the value relates. Two of the Company’s four reporting units have goodwill. The Company tests goodwill by estimating the fair value of the reporting unit using a discounted cash flow model and other valuation techniques, but may elect to perform a qualitative analysis. A quantitative analysis is used to determine an estimated fair value representing the amount at which a reporting unit could be bought or sold in a current transaction between willing parties on an arms-length basis. The estimated fair value of each reporting unit is derived using a discounted cash flow method based on market and reporting unit-specific assumptions, including estimated future revenues and expenses, weighted average cost of capital, capital expenditures, the useful life over which cash flows will occur and other assumptions which are considered reasonable and inherent in discounted cash flow analysis. A qualitative analysis is performed by assessing certain trends and factors, including projected market outlook and growth rates, forecasted and actual sales and operating profit margins, discount rates, industry data and other relevant qualitative factors. These trends and factors are compared to, and based on, the assumptions used in the most recent quantitative assessment. As of December 31, 2019, the Company has written the value of all of its goodwill and intangible assets to zero because the Company determined they were impaired.
Income Taxes	Income Taxes The Company accounts for income taxes under the asset and liability method, based on the income tax laws and rates in the countries in which operations are conducted and income is earned. This approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax basis of assets and liabilities. Developing the provision for income taxes requires significant judgment and expertise in federal, international and state income tax laws, regulations and strategies, including the determination of deferred tax assets and liabilities and, if necessary, any valuation allowances that may be required for deferred tax assets. The Company records a valuation allowance to reduce its deferred tax assets to the amount that is more likely than not to be realized. The Company believes that the deferred tax asset recorded as of December 31, 2019 and 2018 is realizable through future reversals of existing taxable temporary differences and future taxable income. If the Company was to subsequently determine that it would be able to realize deferred tax assets in the future in excess of its net recorded amount, an adjustment to deferred tax assets would increase net income for the period in which such determination was made. The Company will continue to assess the adequacy of the valuation allowance on a quarterly basis. The Company’s tax filings are subject to audit by various taxing authorities. The objective of accounting for income taxes is to recognize the amount of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences or events that have been recognized in the Company’s financial statements or tax returns. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position (see “Unrecognized Tax Benefits” below). Income tax related interest and penalties are grouped with interest expense on the consolidated statement of operations.
Unrecognized Tax Benefits	Unrecognized Tax Benefits The Company accounts for unrecognized tax benefits in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) “Income Taxes” (“ASC 740”). ASC 740 prescribes a recognition threshold that a tax position is required to meet before being recognized in the financial statements and provides guidance on de-recognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition issues. ASC 740 contains a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained upon ultimate settlement with a taxing authority, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. Additionally, ASC 740 requires the Company to accrue interest and related penalties, if applicable, on all tax positions for which reserves have been established consistent with jurisdictional tax laws. See Note 16 ‒ Income Taxes.
Share-Based Payments	Share-Based Payments The Company accounts for share based payments in accordance with the provisions of FASB ASC 718 “Compensation – Stock Compensation” and accordingly recognizes in its financial statements share based payments at their fair value. In addition, it recognizes in the financial statements an expense based on the grant date fair value of stock options granted to employees and directors. The expense is recognized on a straight line basis over the expected option life while taking into account the vesting period and the offsetting credit is recorded in additional paid-in capital. Upon exercise of options, the consideration paid together with the amount previously recorded as additional paid-in capital is recognized as capital stock. The Company estimates its forfeiture rate in order to determine its compensation expense arising from stock based awards. The Company uses the Black-Scholes Merton option pricing model to determine the fair value of the options. Non-employee members of the Board of Directors are deemed to be employees for the purposes of recognizing share-based compensation expense.
Inventories	Inventories Inventories are stated at the lower of cost or net realizable value using first-in, first-out (FIFO) or weighted-average methods and include the cost of materials, labor and manufacturing overhead. The Company uses estimates in determining the level of reserves required to state inventory at the lower of cost or market. The Company estimates are based on market activity levels, production requirements, the physical condition of products and technological innovation. Changes in any of these factors may result in adjustments to the carrying value of inventory. See Note 8 - Inventories.
Income (Loss) Per Share	Income (Loss) Per Share Basic income (loss) per share is computed by dividing the income (loss) for the period by the weighted average number of common shares outstanding during the period. Diluted income (loss) per share is computed by dividing the income (loss) for the period by the weighted average number of common and common equivalent shares outstanding during the period. (See Note 18 ‒ Basic and Diluted Net Loss Per Share).
Fair Value Measurements	Fair Value Measurements FASB ASC 820 “Fair Value Measurement and Disclosure” applies to all assets and liabilities that are being measured and reported on a fair value basis. ASC 820 establishes a framework for measuring fair value in U.S GAAP, and expands disclosure about fair value measurements. ASC 820 enables the reader of the financial statements to assess the inputs used to develop those measurements by establishing a hierarchy for ranking the quality and reliability of the information used to determine fair values. ASC 820 requires that assets and liabilities carried at fair value be classified and disclosed in one of the following three categories: Level 1: Quoted market prices in active markets for identical assets or liabilities. Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data. Level 3: Unobservable inputs that are not corroborated by market data. In determining the appropriate levels, the Company performs a detailed analysis of the assets and liabilities that are subject to ASC 820. At each reporting period, all assets and liabilities for which the fair value measurement is based on significant unobservable inputs are classified as Level 3. The fair value represents management’s best estimates based on a range of methodologies and assumptions. The carrying value of receivables and payables arising in the ordinary course of business approximate fair value because of the relatively short period of time between their origination and expected realization. The Company’s financial instruments consist primarily of cash and cash equivalents, receivables, notes receivable in connection with the Equity Transaction, payables and debt instruments. The carrying values of these financial instruments approximate their respective fair values as they are either short-term in nature or carry interest rates which are periodically adjusted to market rates. Unless otherwise indicated, the carrying value of these financial instruments approximates their fair market value. The carrying amount reported in the consolidated balance sheet for shares held in CleanSpark, Inc. of $936 included within short term investment approximates fair value as the asset has a readily determinable market value and as such it is considered a Level 1 asset. The estimated fair value of the warrants held in CleanSpark, Inc. of approximately $531 is considered a Level 3 asset due to unobservable inputs.

May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. Since then, the FASB has also issued ASU 2016-08, Revenue from Contracts with Customers Principals versus Agent Considerations, Revenue from Contracts with Customers Identifying Performance Obligations and Licensing Revenue Recognition Revenue from Contracts with Customers Leases Leases Amendments to SEC Paragraphs Pursuant to the Staff Announcement at the July 20, 2017 EITF Meeting and Recession of Prior SEC Staff Announcements and Observer Comments, In July 2015, the FASB approved a one-year deferral of the effective date to January 1, 2018, with early adoption to be permitted as of the original effective date of January 1, 2017. Once this standard becomes effective, companies may We completed a review of our various revenue streams within our two reportable segments, T&D Solutions and Critical Power. We have gathered data to quantify the amount of sales by type of revenue stream and categorized the types of sales for our business units for the purpose of comparing how we currently recognize revenue to the new standard in order to quantify the impact of this ASU. We have made policy elections within the amended standard that are consistent with our current accounting. We adopted ASU 2014-09 in our first quarter of 2018 using the modified retrospective approach. We have performed a quantitative assessment of adopting ASU 2014-09 and concluded that there was no material impact to our financial statements other than enhanced disclosures and no changes to the opening retained earnings.
