Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Business, Liquidity and Basis of Presentation	Nature of Business, Liquidity and Basis of Presentation Nature of Business For information on the nature of our business, see Part II, Item 8, Note 1 — Nature of Business, Liquidity and Basis of Presentation, Nature of Business section in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023. Liquidity We have generally incurred operating losses and negative cash flows from operations since our inception. With the series of new debt offerings, debt extinguishments, and conversions to equit y that we completed during 2023, 2022 and 2021 , we had $843.5 million and $4.5 million of total outstanding recourse and non-recourse debt, respectively, as of March 31, 2024 , which was classified as long-term debt. Our future capital requirements depend on many factors, including our rate of revenue growth, the timing and extent of spending on research and development efforts and other business initiatives, the rate of growth in the volume of system builds and the need for additional working capital, the expansion of sales and marketing activities both in domestic and international markets, market acceptance of our products, our ability to secure financing for customer use of our Energy Servers, the timing of installations and of inventory build in anticipation of future sales and installations, and overall economic conditions. In order to support and achieve our future growth plans, we may need or seek advantageously to obtain additional funding through equity or debt financing.

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition Contract Balances The following table provides information about accounts receivables, contract assets, customer deposits and deferred revenue from contracts with customers (in thousands): March 31, December 31, 2024 2023 Accounts receivable $ 348,422 $ 340,740 Contract assets 33,788 41,366 Customer deposits 75,140 75,734 Deferred revenue 59,468 72,328 Contract assets relate to contracts for which revenue is recognized upon transfer of control of performance obligations, but where billing milestones have not been reached. Customer deposits and deferred revenue include payments received from customers or invoiced amounts prior to transfer of control of performance obligations. Contract assets and contract liabilities are reported in a net position on an individual contract basis at the end of each reporting period. Contract assets are classified as current in the condensed consolidated balance sheets when both the milestones other than the passage of time, are expected to be complete and the customer is invoiced within one year of the balance sheet date, and as long-term when both the above-mentioned milestones are expected to be complete, and the customer is invoiced more than one year out from the balance sheet date. Contract liabilities are classified as current in the condensed consolidated balance sheets when the revenue recognition associated with the related customer payments and invoicing is expected to occur within one year of the balance sheet date and as long-term when the revenue recognition associated with the related customer payments and invoicing is expected to occur in more than one year from the balance sheet date. Contract Assets Three Months Ended 2024 2023 Beginning balance $ 41,366 $ 46,727 Transferred to accounts receivable from contract assets recognized at the beginning of the period (18,123) (10,787) Revenue recognized and not billed as of the end of the period 10,545 11,838 Ending balance $ 33,788 $ 47,778 Deferred Revenue Deferred revenue activity during the three months ended March 31, 2024 and 2023, consisted of the following (in thousands): Three Months Ended 2024 2023 Beginning balance $ 72,328 $ 94,355 Additions 176,484 224,939 Revenue recognized (189,344) (231,446) Ending balance $ 59,468 $ 87,848 Deferred revenue is equivalent to the total transaction price allocated to the performance obligations that are unsatisfied, or partially unsatisfied, as of the end of the period. The primary component of deferred revenue at the end of the period consists of performance obligations relating to the provision of maintenance services under current contracts and future renewal periods. Some of these obligations provide customers with material rights over a period that we estimate to be largely commensurate with the period of their expected use of the associated Energy Servers. As a result, we expect to recognize these amounts as revenue over a period of up to 21 years, predominantly on a relative standalone selling price basis that reflects the cost of providing these services. Deferred revenue also includes performance obligations relating to product acceptance and installation. A significant amount of this deferred revenue is reflected as additions and revenue recognized in the same 12-month period, and a portion of this deferred revenue is expected to be recognized beyond this 12-month period mainly due to deployment schedules. We do not disclose the value of the unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed. Disaggregated Revenue We disaggregate revenue from contracts with customers into four revenue categories: product, installation, services and electricity (in thousands): Three Months Ended 2024 2023 Revenue from contracts with customers: Product revenue $ 153,364 $ 193,745 Installation revenue 11,444 20,525 Services revenue 56,460 40,663 Electricity revenue 4,827 3,838 Total revenue from contract with customers 226,095 258,771 Revenue from contracts that contain leases: Electricity revenue 9,203 16,420 Total revenue $ 235,298 $ 275,191

Embedded Escalation Protection Plan Derivative Liability in Sales Contracts — We estimate the fair value of the embedded EPP derivatives in certain sales contracts using a Monte Carlo simulation model, which considers various potential electricity price curves over the sales contracts’ terms. We use historical grid prices and available forecasts of future electricity prices to estimate future electricity prices. We have classified these derivatives as a Level 3 financial liability. The changes in the Level 3 financial liabilities during the three months ended March 31, 2024 were as follows (in thousands): Embedded EPP Derivative Liability Liabilities at December 31, 2023 $ 4,376 Changes in fair value (158) Liabilities at March 31, 2024 $ 4,218 For more details on EPP derivatives, refer to Part II, Item 8 Note 5 — Fair Value in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023 .

Stock Option and Stock Award Activity The following table summarizes the stock option activity under our stock plans during the reporting period: Outstanding Options Number of Weighted Remaining Aggregate (in thousands) Balances at December 31, 2023 7,247,624 $ 20.93 3.8 $ 19,446 Granted 1,000,000 9.08 Exercised (99,640) 5.44 Expired (284,187) 27.03 Balances at March 31, 2024 7,863,797 19.39 4.7 24,003 Vested and expected to vest at March 31, 2024 7,519,528 19.86 4.4 22,034 Exercisable at March 31, 2024 6,859,630 $ 20.89 3.7 $ 18,252 During the three months ended March 31, 2024 and 2023, we recognized $0.2 million and $0.2 million of stock-based compensation costs for stock options, respectively. During the three months ended March 31, 2024 we granted 1,000,000 stock options. We did not grant stock options in the three months ended March 31, 2023. During the three months ended March 31, 2024 and 2023, the intrinsic value of stock options exercised was $0.5 million and $0.8 million, respectively. As of March 31, 2024 and December 31, 2023, we had unrecognized compensation costs related to unvested stock options of $7.0 million and $0.1 million, respectively. This cost is expected to be recognized over the remaining weighted-average period of 3.3 years and 0.3 years, respectively. Cash received from stock options exercised totaled $0.5 million and $0.8 million for the three months ended March 31, 2024 and 2023, respectively. Executive Performance-Based Stock Options During the three months ended March 31, 2024, we granted 955,000 stock options to certain executives to purchase shares of common stock that contain certain performance-based vesting criteria related to corporate milestones (the “performance-based stock options”). The performance-based stock options were granted “at-the-money” and have a term of 10 years. The performance-based stock options vest based over a four-year or a three-year requisite service period. The fair value of each performance-based stock option is estimated on the date of grant using the Black-Scholes valuation model. Recognition of stock-based compensation expense associated with these performance-based stock options commences when the performance condition is considered probable of achievement, using management’s best estimates, which consider the inherent risk and uncertainty regarding the future outcomes of the milestones. Forfeitures of the performance-based stock options are recognized as they occur. We used the following weighted-average assumptions in applying the Black-Scholes valuation model for determination of the performance-based stock options valuation: Three Months Ended March 31, 2024 Risk-free interest rate 4.1% Expected term (years) 6.0 Expected dividend yield — Expected volatility 97.1% Stock Awards A summary of our stock awards activity and related information is as follows: Number of Weighted Unvested Balance at December 31, 2023 9,889,341 $ 18.25 Granted 3,948,296 9.52 Vested (1,483,902) 19.43 Forfeited (707,643) 20.33 Unvested Balance at March 31, 2024 11,646,092 $ 15.01 Stock Awards — The estimated fair value of restricted stock units (“RSUs”) and performance stock units (“PSUs”) is based on the fair value of our Class A common stock on the date of grant. For the three months ended March 31, 2024 and 2023, we recognized $17.9 million and $22.6 million of stock-based compensation costs for stock awards, respectively. As of March 31, 2024 and December 31, 2023, we had $99.5 million and $113.5 million of unrecognized stock-based compensation expense related to unvested stock awards, expected to be recognized over a weighted average period of 2.3 years and 2.0 years, respectively. Executive Awards On March 1, 2024, the Company granted RSU, PSU and the performance-based stock option awards (the “2024 Executive Awards”) to certain executive staff pursuant to the 2018 Equity Incentive Plan. The RSUs have time-based vesting schedules, started vesting on January 15, 2024 and shall vest over a four-year period. The PSUs have either a four-year, a three-year, or a one-year cliff vesting period, and the performance-based stock options have either a four-year or a three-year cliff vesting period. The PSUs and performance-based stock options will vest based on a combination of time and achievement against performance metrics targets assuming continued employment and service through each vesting date. Stock-based compensation costs associated with the 2024 Executive Awards are recognized over the service period as we evaluate the probability of the achievement of the performance conditions. As of March 31, 2024, the unamortized compensation expense for the RSUs, PSUs, and the performance-based stock options per the 2024 Executive Awards was $9.4 million. For details on the 2023, 2022, and 2021 Executive Awards refer to Part II, Item 8, Note 9 — Stock-Based Compensation and Employee Benefit Plans in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

Restructuring and Related Activities [Abstract]
Restructuring	Restructuring In September 2023, as a result of a review of current strategic priorities and resource allocation, we approved the restructuring plan (the “Restructuring Plan”) intended to realign our operational focus to support our multi-year growth, scale the business, and improve our cost structure and operating margins. Please refer to Part II, Item 8, Note 12 — Restructuring in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, for details. For the three months ended March 31, 2024, impact from restructuring on our condensed consolidated statements of operations was not material. We expect to incur $6.3 million in restructuring costs in subsequent quarters, out of which we expect $3.5 million will relate to relocation costs, $2.0 million will relate to the facility closure costs, and $0.8 million will relate to other restructuring costs. However, the actual timing and amount of costs associated with these restructuring actions may differ from our current expectations and estimates and such differences may be material. The following table presents our current liability as accrued for restructuring charges on our condensed consolidated balance sheets. The table sets forth an analysis of the components of the restructuring charges and payments made against the accrual for the three months ended March 31, 2024 (in thousands): Three Months Ended March 31, 2024 Facility Closure Severance Other Total Balance at December 31, 2023 $ 2,577 $ 464 $ 752 $ 3,793 Restructuring accrual (release) (89) (385) 86 (388) Payments (822) (79) (577) (1,478) Balance at March 31, 2024 $ 1,666 $ — $ 261 $ 1,927 At March 31, 2024 and December 31, 2023, facility closure costs, severance, and other restructuring costs were included in accrued expenses and other current liabilities in our condensed consolidated balance sheets.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Commitments Purchase Commitments with Suppliers and Contract Manufacturers — In order to reduce manufacturing lead-times for an adequate supply of inventories, we have agreements with our component suppliers and contract manufacturers to allow long lead-time component inventory procurement based on a rolling production forecast. We are contractually obligated to purchase long lead-time component inventory procured by certain manufacturers in accordance with our forecasts. We can generally give notice of order cancellation at least 90 days prior to the delivery date. However, we occasionally issue purchase orders to our component suppliers and third-party manufacturers that are not cancellable. As of March 31, 2024 and December 31, 2023, we had no material open purchase orders with our component suppliers and third-party manufacturers that are not cancellable. Performance Guarantees — We guarantee the performance of the Energy Servers at certain levels of output and efficiency to our customers over the contractual term. We monitor the need for any accruals arising from such guaranties, which are calculated as the difference between committed and actual power output or between natural gas consumption at warranted efficiency levels and actual consumption, multiplied by the contractual rates with the customer. Amounts payable under these guaranties are accrued in periods when the guaranties are not met and are recorded as service revenue in the condensed consolidated statements of operations. We paid $15.1 million and $15.8 million for the three months ended March 31, 2024 and 2023, respectively, for such performance guarantees. Letters of Credit — In 2019, pursuant to the PPA II upgrade of the Energy Servers, we agreed to indemnify our financing partner for losses that may be incurred in the event of certain regulatory, legal or legislative developments and established a cash-collateralized letter of credit facility for this purpose. As of March 31, 2024 and December 31, 2023, the balance of this cash-collateralized letter of credit was $26.9 million and $40.4 million, respectively. In addition, we have other outstanding letters of credit issued to our customers and other counterparties in the U.S. and international locations under different performance and financial obligations. These letters of credit are collateralized through cash deposited in the controlled bank accounts with the issuing banks and are classified as restricted cash in our condensed consolidated balance sheets. As of March 31, 2024 and December 31, 2023, the balances of the cash-collateralized letters of credit issued to our customers and other counterparties in the U.S. and international locations were $32.5 million and $32.6 million, respectively. Pledged Funds — In 2019, pursuant to the PPA IIIb upgrade of the Energy Servers, we established a restricted cash fund of $20.0 million, which had been pledged for a seven-year period to secure our operations and maintenance obligations with respect to the totality of our obligations to the financier. All or a portion of such funds would be released if we meet certain credit rating and/or market capitalization milestones prior to the end of the pledge period. If we do not meet the required criteria within the first five-year period, the funds would still be released to us over the following two years as long as the Energy Servers continue to perform in compliance with our warranty obligations. As of March 31, 2024 and December 31, 2023, the balance of the restricted cash fund was $7.4 million and $7.6 million, respectively. Contingencies Indemnification Agreements — We enter into standard indemnification agreements with our customers and certain other business partners in the ordinary course of business. Our exposure under these agreements is unknown because it involves future claims that may be made against us but have not yet been made. To date, we have not paid any claims or been required to defend any action related to our indemnification obligations. However, we may record charges in the future as a result of these indemnification obligations. Investment Tax Credits — Our Energy Servers are eligible for federal Income Tax Credits (the “ITC”) that accrued to qualified property under Internal Revenue Code Section 48 when placed into service. However, the ITC program has operational criteria that extend for five years. If the energy property is disposed of or otherwise ceases to be qualified investment credit property before the close of the five-year recapture period is fulfilled, it could result in a partial reduction of the incentives. Legal Matters — We are involved in various legal proceedings that arise in the ordinary course of business. We review all legal matters at least quarterly and assess whether an accrual for loss contingencies needs to be recorded. We record an accrual for loss contingencies when management believes that it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Legal matters are subject to uncertainties and are inherently unpredictable, so the actual liability in any such matter may be materially different from our estimates. If an unfavorable resolution were to occur, there exists the possibility of a material adverse impact on our consolidated financial condition, results of operations or cash flows for the period in which the resolution occurs or in future periods. In March 2019, the Lincolnshire Police Pension Fund filed a class action complaint in the Superior Court of the State of California, County of Santa Clara, against us, certain members of our senior management, certain of our directors and the underwriters in our July 25, 2018 IPO alleging violations under Sections 11 and 15 of the Securities Act for alleged misleading statements or omissions in our Registration Statement on Form S-1 filed with the SEC in connection with the IPO. Two related class action cases were subsequently filed in the Santa Clara County Superior Court against the same defendants containing the same allegations; Rodriquez vs Bloom Energy et al. was filed on April 22, 2019 and Evans vs Bloom Energy et al. was filed on May 7, 2019. These cases have been consolidated. Plaintiffs’ consolidated amended complaint was filed with the court on September 12, 2019. On October 4, 2019, defendants moved to stay the lawsuit pending the federal district court action discussed below. On December 7, 2019, the Superior Court issued an order staying the action through resolution of the parallel federal litigation mentioned below. We believe the complaint to be in contravention of our forum selection clause in our Restated Certificate of Incorporation and we intend to defend this action vigorously. We are unable to estimate any range of reasonably possible losses. In May 2019, Elissa Roberts filed a class action complaint in the federal district court for the Northern District of California against us, certain members of our senior management team, and certain of our directors’ alleging violations under Sections 11 and 15 of the Securities Act for alleged misleading statements or omissions in our Registration Statement on Form S-1 filed with the SEC in connection with the IPO. On September 3, 2019, the court appointed a lead plaintiff and lead plaintiffs’ counsel. On November 4, 2019, plaintiffs filed an amended complaint adding the underwriters in the IPO and our auditor as defendants for the Section 11 claim, as well as adding claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), against us, and certain members of our senior management team. The amended complaint alleged a class period for all claims from the time of our IPO until September 16, 2019. On April 21, 2020, plaintiffs filed a second amended complaint, which continued to make the same claims and added allegations pertaining to the restatement and, as to claims under the Exchange Act, extended the putative class period through February 12, 2020. On July 1, 2020, we and the other defendants filed motions to dismiss the second amended complaint. On September 29, 2021, the court entered an order dismissing with leave to amend (1) five of seven statements or groups of statements alleged to violate Sections 11 and 15 of the Securities Act and (2) all allegations under the Exchange Act. All allegations against our auditors were also dismissed. Plaintiffs elected not to amend the complaint and instead on October 22, 2021 filed a motion for entry of final judgment in favor of our auditors so that plaintiffs could appeal the dismissal of those claims. The court denied that motion on December 1, 2021 and in response plaintiffs filed a motion asking the court to certify an interlocutory appeal as to the accounting claims. The court denied plaintiffs’ motion on April 14, 2022. The claims for violation of Sections 11 and 15 of the Securities Act that were not dismissed by the court entered the discovery phase. On January 6, 2023, Bloom and the plaintiffs’ entered into an agreement in principle to settle the claims against Bloom, its executives and directors, and the IPO underwriters for a payment of $3.0 million, which we expect to be funded entirely by our insurers. If the settlement becomes effective, we expect it to result in a dismissal with prejudice of all claims against us, our executives and directors, and the underwriters. The settlement does not constitute an acknowledgement of liability or wrongdoing. On June 30, 2023, Bloom and the plaintiff’s executed a definitive settlement agreement containing the foregoing terms and customary terms for class action settlements, and on the same date, filed the settlement agreement with the court to seek its approval. The judge issued a preliminary approval of the settlement on October 31, 2023. Notice of the settlement together with requested Plaintiff attorney fees was sent to the defined class of Bloom stockholders and on May 2, 2024 the final settlement was approved. In June 2021, we filed a petition for writ of mandate and a complaint for declaratory and injunctive relief in the Santa Clara Superior Court against the City of Santa Clara for failure to issue building permits for two of our customer installations and asking the court to require the City of Santa Clara to process and issue the building permits. In October 2021, we filed an amended petition and complaint that asserts additional constitutional and tort claims based on the City’s failure to timely issue the Energy Server permits. On April 21, 2023, the parties executed a settlement agreement which allows our two pending customer installations to proceed under building permits and requires the City of Santa Clara to amend its zoning code so that future installations of Bloom Energy Servers in Santa Clara require only building permits. In February 2022, Plansee SE/Global Tungsten & Powders Corp. (“Plansee/GTP”), a former supplier, filed a request for expedited arbitration with the World Intellectual Property Organization Arbitration and Mediation Center in Geneva Switzerland (“WIPO”), for various claims allegedly in relation to an Intellectual Property and Confidential Disclosure Agreement between Plansee/GTP and Bloom Energy Corporation. Plansee/GTP’s statement of claims includes allegations of infringement of U.S. Patent Nos. 8,802,328, 8,753,785 and 9,434,003. On April 3, 2022, we filed a complaint against Plansee/GTP in the Eastern District of Texas to address the dispute between Plansee/GTP and Bloom Energy Corporation in a proper forum before a U.S. Federal District Court. Our complaint seeks the correction of inventorship of U.S. Patent Nos. 8,802,328, 8,753,785 and 9,434,003 (the “Patents-in-Suit”); declaratory judgment of invalidity, unenforceability, and non-infringement of the Patents-in-Suit; and declaratory judgment of no misappropriation. Further, our complaint seeks to recover damages we have suffered in relation to Plansee/GTP’s business dealings that, as alleged, constitute acts of unfair competition, tortious interference contract, breach of contract, violations of the Racketeer Influenced and Corrupt Organizations (RICO) Act and violations of the Clayton Antitrust Act. On June 9, 2022, Plansee/GTP filed a motion to dismiss the complaint filed in the Eastern District of Texas and compel arbitration (or alternatively to stay). We filed our opposition on June 30, 2022, Plansee/GTP filed its reply on July 14, 2022 and we filed our sur-reply on July 22, 2022. On February 9, 2023, Magistrate Judge Payne issued a report and recommendation to stay the district court action pending an arbitrability determination by the arbitrator for each claim. On February 23, 2023, we filed an amended complaint adding additional causes of action and filed objections to the Magistrate’s report and recommendation. On April 26, 2023, Judge Gilstrap overruled our objections to the Magistrate’s report and recommendation and stayed the district court action pending arbitrability determinations by the arbitrator in the WIPO proceeding. The arbitration had been held in abeyance awaiting the decision of the Eastern District of Texas. A hearing by the arbitrator in WIPO on arbitrability took place on June 27, 2023. On October 2, 2023, the arbitrator in the WIPO proceeding issued a ruling concluding that all the parties’ claims were arbitrable. On November 18, 2023, the arbitrator bifurcated the arbitration into a first phase that will focus on Bloom’s claims directed to improper inventorship of the Patents-in-Suit and Bloom’s defective product claims. Briefing on the first phase will take place throughout 2024 with a potential evidentiary hearing to be scheduled in 2025. We are unable to predict the ultimate outcome of the arbitration at this time.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three months ended March 31, 2024 and 2023, we recorded an income tax (benefit) provisions of $(0.5) million and $0.3 million on pre-tax losses of $57.0 million and $74.7 million for effective tax rates of 0.9% and (0.3)%, respectively. The effective tax rate for the three months ended March 31, 2024 and 2023, is lower than the statutory federal tax rate primarily due to a full valuation allowance against U.S. deferred tax assets. New Foreign Tax Rules In 2021, the Organization for Economic Co-operation and Development announced an Inclusive Framework on Base Erosion and Profit Shifting, including Pillar Two Model Rules defining a global minimum tax, which calls for the taxation of large multinational corporations at a minimum rate of 15%. Subsequently, multiple sets of administrative guidance have been issued. Many non-U.S. tax jurisdictions have either recently enacted legislation to adopt certain components of the Pillar Two Model Rules beginning in 2024 (including the European Union Member States) with the adoption of additional components in later years or announced their plans to enact legislation in future years. We are continuing to evaluate the impacts of enacted legislation and pending legislation to enact Pillar Two Model Rules in the non-U.S. tax jurisdictions we operate in. However, legislation enacted as of March 31, 2024 did not have a material impact on our financial statements for the three months ended March 31, 2024 and is not expected to have a material impact on our 2024 financial statements due to the relatively small operations outside the U.S.
