Equity Method Investments and Joint Ventures [Abstract]
Equity Method Investments and Joint Ventures Disclosure [Text Block]	8POINT3 ENERGY PARTNERS LP In June 2015, 8point3 Energy Partners LP ("8point3 Energy Partners"), a joint YieldCo vehicle formed by the Company and First Solar, Inc. ("First Solar" and, together with the Company, the "Sponsors") to own, operate and acquire solar energy generation assets, completed an initial public offering (“IPO”) of Class A shares representing limited partner interests in 8point3 Energy Partners. The IPO was consummated on June 24, 2015 (the “IPO Closing Date”) whereupon the Class A shares were listed on the NASDAQ Global Select Market under the trading symbol “CAFD.” Immediately after the IPO, the Company contributed a portfolio of 170 MW of its solar generation assets (the “SPWR Projects”) to 8point3 Operating Company, LLC ("OpCo"), 8point3 Energy Partners' primary operating subsidiary. In exchange for the SPWR Projects, the Company received cash proceeds of $371 million as well as equity interests in several 8point3 Energy Partners affiliated entities: primarily common and subordinated units representing a 40.7% stake in OpCo and a 50.0% economic and management stake in 8point3 Holding Company, LLC (“Holdings”), the parent company of the general partner of 8point3 Energy Partners and the owner of incentive distribution rights (“IDRs”) in OpCo. Holdings, OpCo, 8point3 Energy Partners and their respective subsidiaries are referred to herein as the “8point3 Group.” Additionally, pursuant to a Right of First Offer Agreement between the Company and OpCo, the 8point3 Group has rights of first offer on interests in an additional 513 MW of the Company’s solar energy projects that are currently contracted or are expected to be contracted before being sold by the Company (the “ROFO Projects”). In connection with the IPO, the Company also entered into operations and maintenance, asset management and management services agreements with the 8point3 Group. The services the Company provides under these agreements are priced consistently with market rates for such services and the agreements are terminable by the 8point3 Group for convenience. The Company accounts for its investments in the 8point3 Group using the equity method, whereby the book value of the Company’s investments is recorded as a non-current asset and the Company’s portion of the 8point3 Group’s earnings is recorded in the Consolidated Statements of Operations under the caption "Equity in earnings (loss) of unconsolidated investees." Refer to Note 10 for further discussion of the Company’s equity method investments in the 8point3 Group. The Company’s agreements with the 8point3 Group include substantive, non-standard guarantees of minimum cash flows in respect of each project among the SPWR Projects that had not yet reached its commercial operations date (“COD”) before the IPO Closing Date. The Company’s guarantees relating to each such project expire when the project reaches COD. The Company therefore determined that the risks and rewards of ownership in these projects are not transferred until COD and, accordingly, the Company continues to record the projects on its Consolidated Balance Sheet until that time. Projects that had not reached COD by June 28, 2015 totaled 131 MW of the SPWR Projects and the Company recorded $302 million of IPO proceeds attributable to those projects as a current liability within “Accrued liabilities” in the Consolidated Balance Sheets. The projects discussed in the previous paragraph, which had not reached COD by June 28, 2015, are projects that include the sale or lease of real estate. Accordingly, each of these projects will be evaluated under relevant guidance for real estate transactions after COD and the concomitant expiration of the Company’s non-standard guarantees (and associated risks of ownership) in respect of the project. The Company determined that the subordination of certain of its OpCo units until such time that the 8point3 Group achieves certain cash distribution targets in respect of the OpCo common and subordinated units (the “subordination period”) constituted a form of support to the operations of the SPWR Projects that also survived the sale of the projects. Accordingly, the Company will defer recognition of any profit on the sale of any such project until unconditional cash proceeds from the sale exceed the Company’s total costs incurred in connection with the project. The Company has reflected the $302 million of IPO cash proceeds attributable to these assets as an investing cash inflow in the Consolidated Statement of Cash Flows. The balance of the SPWR Projects was composed of a portfolio of residential leases (the “residential lease portfolio”) which included both sales-type and operating leases. The Company evaluated the sale of the residential lease portfolio, excluding the portion related to operating leases and unguaranteed residual values accounted for under lease guidance in the following paragraph, under relevant accounting guidance for consolidations and determined that this portion of the residential lease portfolio met the definition of a business and that deconsolidation criteria were met. The Company received cash proceeds of $39 million and equity proceeds of $68 million attributable to the sale of this portion of the residential lease portfolio and recorded a resulting $28 million gain upon deconsolidation, reflected in “Other, net” in the Consolidated Statements of Operations. The equity proceeds were valued using the income approach which utilized a discounted cash flow model based on forecasted cash flows, indexed to 8point3 Energy Partners' IPO price of $21 per Class A share. The Company has reflected the $39 million of IPO cash proceeds attributable to this portion of the residential lease portfolio as an investing cash inflow in the Consolidated Statement of Cash Flows. The Company evaluated the sale of the portion of the residential lease portfolio that was composed of operating leases and unguaranteed sales-type lease residual values under relevant guidance for leasing transactions and determined that the Company retained significant risks of ownership as defined in such guidance due, in part, to the subordination of certain of the Company’s OpCo units during the subordination period. Accordingly, the Company accounted for the sale of the operating leases and the unguaranteed sales-type lease residual values as a borrowing and reflected the $29 million of IPO cash proceeds attributable to this portion of the residential lease portfolio as a financing cash inflow in the Consolidated Statement of Cash Flows and as liabilities recorded within “Accrued liabilities” and “Other long-term liabilities” in the Consolidated Balance Sheets.
