Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Business, Liquidity, Basis of Presentation	Nature of Business, Liquidity and Basis of Presentation Nature of Business We design, manufacture, sell and, in certain cases, install solid-oxide fuel cell systems ("Energy Servers") for on-site power generation. Our Energy Servers utilize an innovative fuel cell technology and provide efficient energy generation with reduced operating costs and lower greenhouse gas emissions as compared to conventional fossil fuel generation. By generating power where it is consumed, our energy producing systems offer increased electrical reliability and improved energy security while providing a path to energy independence. We continue to monitor and adjust as appropriate our operations in response to the COVID-19 pandemic. There have been a number of supply chain disruptions throughout the global supply chain as countries are in various stages of opening up and demand for certain components increases. Although we were able to find alternatives for many component shortages, we experienced some delays and cost increases with respect to container shortages, ocean shipping and air freight. Liquidity We have generally incurred operating losses and negative cash flows from operations since our inception. With the series of new debt offerings, debt extensions and conversions to equity that we completed during 2020, we had $291.3 million of total outstanding recourse debt as of September 30, 2021, $285.2 million of which is classified as long-term debt. Our recourse debt scheduled repayments will commence in June 2022. On October 23, 2021, we entered into a Securities Purchase Agreement (the “SPA”) with SK ecoplant Co., Ltd. (formerly known as SK Engineering and Construction Co., Ltd.) ("SK ecoplant") in connection with a strategic partnership. Pursuant to the SPA, we have agreed to sell to SK ecoplant 10,000,000 shares of zero coupon, non-voting redeemable convertible Series A preferred stock in Bloom Energy, par value $0.0001 per share, at a purchase price of $25.50 per share or an aggregate purchase price of approximately $255.0 million. For more information about the SPA, please see Note 18 - Subsequent Events, and for more information about our joint venture with SK ecoplant, please see Note 12 - Related Party Transactions. Our future capital requirements will 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 manufacturing space, the expansion of sales and marketing activities both in domestic and international markets, market acceptance of our product, our ability to secure financing for customer use of our Energy Servers, the timing of installations, and overall economic conditions including the impact of COVID-19 on our ongoing and future operations. In the opinion of management, the combination of our existing cash and cash equivalents and operating cash flows is expected to be sufficient to meet our operational and capital cash flow requirements and other cash flow needs for the next 12 months from the date of issuance of this Quarterly Report on Form 10-Q. Basis of Presentation We have prepared the condensed consolidated financial statements included herein pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC"), and as permitted by those rules, including all disclosures required by generally accepted accounting principles as applied in the United States (“U.S. GAAP”). Certain prior period amounts have been reclassified to conform to the current period presentation. As disclosed in the 2020 Annual Report on Form 10-K, effective on December 31, 2020, we lost our emerging growth company status which accelerated the adoption of Accounting Standards Codification ("ASC") 842, Leases ("ASC 842"). As a result, we adjusted our previously reported condensed consolidated financial statements effective January 1, 2020. Principles of Consolidation These condensed consolidated financial statements reflect our accounts and operations and those of our subsidiaries in which we have a controlling financial interest. We use a qualitative approach in assessing the consolidation requirement for each of our variable interest entities ("VIEs"), which we refer to as a tax equity partnership (each such VIE, also referred to as our power purchase agreement entities ("PPA Entities")). This approach focuses on determining whether we have the power to direct those activities of the PPA Entities that most significantly affect their economic performance and whether we have the obligation to absorb losses, or the right to receive benefits, that could potentially be significant to the PPA Entities. For all periods presented, we have determined that we are the primary beneficiary in all of our operational PPA Entities, as discussed in Note 11 - Portfolio Financings. We evaluate our relationships with the PPA Entities on an ongoing basis to ensure that we continue to be the primary beneficiary. All intercompany transactions and balances have been eliminated upon consolidation. The sale of an operating company with a portfolio of PPAs in which we do not have an equity interest is called a “Third-Party PPA.” We have determined that, although these entities are VIEs, we do not have the power to direct those activities of the Third-Party PPAs that most significantly affect their economic performance. We also do not have the obligation to absorb losses, or the right to receive benefits, that could potentially be significant to the Third-Party PPAs. Because we are not the primary beneficiary of these activities, we do not consolidate Third-Party PPAs. Business Combinations Acquisitions of a business are accounted by using the acquisition method of accounting. Assets acquired and liabilities assumed, including amounts attributed to noncontrolling interests, are recorded at the acquisition date at their fair values. Assigning fair values requires us to make significant estimates and assumptions regarding the fair value of identifiable intangible assets, property, plant and equipment, deferred tax asset valuation allowances and liabilities, such as uncertain tax positions and contingencies. We may refine these estimates if necessary over a period not to exceed one year by taking into consideration new information that, if known at the acquisition date, would have affected the fair values ascribed to the assets acquired and liabilities assumed. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and the accompanying notes. The most significant estimates include the determination of the stand-alone selling price, including material rights estimates, inventory valuation, specifically excess and obsolescence provisions for obsolete or unsellable inventory and, in relation to property, plant and equipment (specifically Energy Servers), assumptions relating to economic useful lives and impairment assessments. Other accounting estimates include variable consideration relating to product performance guaranties, lease and non-lease components and related financing obligations such as incremental borrowing rates, estimated output, efficiency and residual value of the Energy Servers, product performance warranties and guaranties and extended maintenance, derivative valuations, estimates for recapture of the U.S. Investment Tax Credit ("ITC") and similar federal tax benefits, estimates relating to contractual indemnities provisions, estimates for income taxes and deferred tax asset valuation allowances, stock-based compensation expense and the fair value of contingent consideration related to business combinations. In addition, because the duration and severity of the COVID-19 pandemic remains uncertain, certain of such estimates could require further judgment or modification and therefore carry a higher degree of variability and volatility. Actual results could differ materially from these estimates under different assumptions and conditions. Concentration of Risk Geographic Risk - The majority of our revenue and long-lived assets are attributable to operations in the United States for all periods presented. Additionally, we sell our Energy Servers in Japan, India and the Republic of Korea (collectively, the "Asia Pacific region"). In the three and nine months ended September 30, 2021, total revenue in the Asia Pacific region was 36% and 38%, respectively, of our total revenue. In the three and nine months ended September 30, 2020, total revenue in the Asia Pacific region was 24% and 30%, respectively, of our total revenue. Credit Risk - At September 30, 2021 and December 31, 2020, SK ecoplant, accounted for approximately 22% and 56% of accounts receivable, respectively. At September 30, 2021, RAD Bloom Project Holdco LLC, accounted for approximately 16% of accounts receivable and none at December 31, 2020. At September 30, 2021, Bronx Community Clean Energy Project accounted for approximately 18% of accounts receivable and none at December 31, 2020. To date, we have not experienced any credit losses. Customer Risk - During the three months ended September 30, 2021, one customer represented 35% of our total revenue. During the nine months ended September 30, 2021, two customers represented 37% and 12% of our total revenue, respectively.
