Significant estimates include estimates used to record purchase price allocation for the Company's acquisitions, fair value measurements used in goodwill impairment tests, impairment estimations of long-lived assets, revenue recognition on cost-to-cost type contracts, allowances for uncollectible accounts, valuations of non-cash capital stock issuances, estimates of the incremental borrowing rate for long-term leases, fair value estimates and the valuation allowance on deferred tax assets.

Revenue from Contract with Customer [Text Block]	4. REVENUE FROM CONTRACTS WITH CUSTOMERS The Electric Power segment provides full service building, maintenance and support to the electrical power distribution, transmission, substation, and emergency response sectors of North America through Front Line Power, Orbital Power Services and Eclipse Foundation. The Telecommunications segment composed of Gibson Technical Services and subsidiaries provides technical implementation, design, maintenance, emergency and repair support services in the broadband, wireless, and outside plant and building technologies. The Renewables segment, Orbital Solar Services, provides engineering, procurement and construction (“EPC”) services that support the development of renewable energy generation focused on utility scale solar and community solar construction. For our construction contracts, revenue is generally recognized over time. Our fixed price and unit-price construction projects generally use a cost-to-cost input method or an output method to measure our progress towards complete satisfaction of the performance obligation as we believe it best depicts the transfer of control to the customer. Under the cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Under the output method, progress towards completion is measured based on units of work completed based on the contractual pricing amounts. Under the output method, revenue is determined by actual work achieved. For jobs under the output method, revenue is earned based on each unit in the contract completed. We construct comprehensive revenue calculations based on quantifiable measures of actual units completed multiplied by the agreed upon contract prices per item completed. Revenue is also generally recognized over time as the customer simultaneously receives and consumes the benefits of our performance as we perform the service. The timing of revenue recognition also depends on the payment terms of the contract, as our performance does not not not For our service contracts, revenue is also generally recognized over time as the customer simultaneously receives and consumes the benefits of our performance as we perform the service. For our fixed price service contracts with specified service periods, revenue is generally recognized on a straight-line basis over such service period when our inputs are expended evenly, and the customer receives and consumes the benefits of our performance throughout the contract term. For certain of our revenue streams, such as call-out repair and service work, and outage services, that are performed under time and materials contracts, our progress towards complete satisfaction of such performance obligations is measured using an input method as the customer receives and consumes the benefits of our performance completed to date. Due to uncertainties inherent in the estimation process, it is possible that estimates of costs to complete a performance obligation will be revised in the near-term. For those performance obligations for which revenue is recognized using a cost-to-cost input method, changes in total estimated costs, and related progress towards complete satisfaction of the performance obligation, are recognized on a cumulative catch-up basis in the period in which the revisions to the estimates are made. When the current estimate of total costs for a performance obligation indicates a loss, a provision for the entire estimated loss on the unsatisfied performance obligation is made in the period in which the loss becomes evident. Accounts Receivable, Contract Assets and Contract Liabilities Accounts receivable are recognized in the period when our right to consideration is unconditional. We also assess our customer's ability and intention to pay, which is based on a variety of factors, including our historical payment experience with and the financial condition of our customers. Payment terms and conditions vary by contract, and are within industry standards across our business lines. Accounts receivable are recognized net of an allowance for doubtful accounts. The timing of revenue recognition may not Contract liabilities from our construction contracts occur when amounts invoiced to our customers exceed revenues recognized under the cost-to-cost or output method measure of progress. Contract liabilities additionally include advanced payments from our customers on certain contracts and provision for future contract losses for those contracts estimated to close in a gross loss position. Contract liabilities decrease as we recognize revenue from the satisfaction of the related performance obligation and are recorded as either current or long-term, depending upon when we expect to recognize such revenue.

Any adjustments to net revenues, cost of revenues, and the related impact to operating income are recognized as necessary in the period they become known. These adjustments may may may not one one Performance Obligations Satisfied Over Time To determine the proper revenue recognition method for our contracts, we evaluate whether a single contract should be accounted for as more than one For most of our contracts, the customer contracts with us to provide a significant service of integrating a complex set of tasks and components into a single project or capability (even if that single project results in the delivery of multiple units). Hence, the entire contract is accounted for as one may one one Variable Consideration The nature of our contracts gives rise to several types of variable consideration. In rare instances, we include in our contract estimates, additional revenue for submitted contract modifications or claims against the customer when we believe we have an enforceable right to the modification or claim, the amount can be estimated reliably and its realization is probable. In evaluating these criteria, we consider the contractual/legal basis for the claim, the cause of any additional costs incurred, the reasonableness of those costs and the objective evidence available to support the claim. These amounts are included in our calculation of net revenue recorded for our contracts and the associated remaining performance obligations. Additionally, if the contract has a provision for liquidated damages in the case that the Company misses a timing target, or fails to meet any other contract benchmarks, the Company accounts for those estimated liquidated damages as variable consideration and will adjust revenue accordingly with periodic updates to the estimated variable consideration as the job progresses. Liquidated damages are recognized as variable consideration and are estimated based on the most likely amount that is deemed probable of realization. Significant Judgments Our contracts with certain customers may may At times, customers may not Our contracts with customers often include promises to transfer multiple products and services to a customer. Determining whether products and services are considered distinct performance obligations that should be accounted for separately rather than together may not In contracts where there are timing differences between when we transfer a promised good or service to the customer and when the customer pays for that good or service, we have determined that, our contracts do not The following tables present the Company's revenues disaggregated by the type of customer: For the Three Months For the Three Months Ended March 31, 2022 Ended March 31, 2021 (in thousands) Electric Power Telecommunications Renewables Total Electric Power Telecommunications Renewables Total Utilities $ 39,251 $ — $ — $ 39,251 $ 3,189 $ — $ — $ 3,189 Telecommunications — 16,095 — 16,095 — — — — Solar — — 14,464 14,464 — — 2,372 2,372 Other 444 — — 444 — — — — Total revenues $ 39,695 $ 16,095 $ 14,464 $ 70,254 $ 3,189 — $ 2,372 $ 5,561 The following tables present the Company's revenues disaggregated by type of contract: For the Three Months For the Three Months Ended March 31, 2022 Ended March 31, 2021 (in thousands) Electric Power Telecommunications Renewables Total Electric Power Telecommunications Renewables Total Cost-plus contracts $ 17,237 $ 112 $ — $ 17,349 $ 1,354 $ — $ — $ 1,354 Fixed price contracts 7,742 2,319 14,464 24,525 470 — 2,372 2,842 Unit price contracts 14,716 13,664 — 28,380 1,365 — — 1,365 Total revenues $ 39,695 $ 16,095 $ 14,464 $ 70,254 $ 3,189 $ — $ 2,372 $ 5,561

[1]	Includes vehicle and equipment loans with interest rates ranging from 1.00% to 9.15%.
[2]	On March 23, 2021, the Company completed a note payable agreement with an institutional investor with a face amount of $10.7 million, a stated interest rate of 9.0%, an estimated effective interest rate of 19.6%, and an original issue discount of $1.0 million. The carrying value was $4.5 million at March 31, 2022. The note payable is payable within eighteen (18) months after the purchase date and the creditor may request payment of up to $1 million per calendar month beginning 6 months after initial issuance. On May 11, 2021, the Company completed note payable agreement with the institutional investor with a face amount of $10.7 million, a stated interest of 9.0% per annum and a combined original issue discount and unamortized prepaid fees of $1.0 million and a carrying value of $7.8 million at March 31, 2022. The net proceeds were to be used for working capital, future acquisitions and general corporate purposes. Beginning six (6) months from the purchase price date, investor has the right, in its sole and absolute discretion, to redeem all or any portion of the Note (such amount, the “Redemption Amount”) subject to the maximum monthly redemption amount of $1 million per calendar month, by providing Company with a “Redemption Notice," and is payable in full within 18 months of issuance. On December 20, 2021, the Company completed a note payable agreement with the institutional investor with a face amount of $16.1 million, a stated interest rate of 9.0%, an estimated effective interest rate of 16.3%, and an original issue discount of $1.1 million. The note payable is payable within eighteen (18) months after the purchase date and the creditor may request payment of up to $1.5 million per month beginning 6 months after initial issuance. The carrying value was $15.7 million at March 31, 2022. The Company has not made any payments on this note as of March 31, 2022. For payments made by exchanging stock for payments against the debt in 2022, the Company recorded a total loss of $0.7 million on the exchanges due to the Company issuing shares at a lower price than the current market price on the dates of exchange.
[3]	On November 17, 2021, the Company entered into two unsecured promissory notes, one with Kurt A Johnson, Jr, for $34,256,000 and the second for $51,384,000 with Tidal Power Group LLC. These promissory notes bear an interest rate of 6% per annum and as modified, $20 million is due on May 6, 2022, $15 million is due on December 31, 2022, and $52 million is due on May 31, 2023. On December 10, 2021, Kurt A Johnson Jr. received an additional unsecured promissory note in the principal sum of $1,090,000 also with a 6% per annum interest rate in exchange for a reduction of shares issued to Mr. Johnson of 400,000. Additionally in a Q1 2022 amendment to the note, the Company also agreed to reduce the restriction period under the Tidal Lockup letter from two years to one year and to the extent that if the value of the shares previously issued to Tidal Power were less than $4.00 per share upon expiration of the restriction period, the Company has agreed to pay additional consideration to Tidal Power so that the value of Tidal Power's shares are equal to no less than $28,852,844. For the Johnson lockup letter, the Company agreed to pay additional consideration to Mr. Johnson upon expiration of the restriction period so that the value of his stock consideration is no less than $17,635,228, which is equal to $4.00 per common share. Any shortfall would be made up by issuing Mr. Johnson additional common shares. See Subsequent Event footnote 20 for more information on amendments to these Promissory notes. See Debt modification subheading below for more information on the debt modification of the unsecured promissory notes.

[1]	On November 17, 2021, the Company entered into a credit agreement and associated documents (the “Credit Agreement”) with Alter Domus (US), LLC (“Alter Domus”), as administrative agent and collateral agent and various lenders (the “Lenders”) in order to enable the Company to finance the acquisition of Front Line Power Construction, LLC. The Lenders made a Term Loan to Front Line in the initial principal amount of $105,000,000 for the purposes of financing the acquisition and the associated expenses. The term loan initially bears interest at the three-month Adjusted LIBOR Rate, plus the Applicable Margin, of which 2.5% may be paid in-kind. The Term Loan shall be repaid in consecutive quarterly installments of $262,500, commencing on June 30, 2022.
