___________
(1) | Affiliate energy, other and capacity revenues reflect revenues on transactions between wholesale and retail affiliates excluding affiliate activity related to leases and derivative instruments. All such activity supports retail supply needs from the wholesale business and/or allows for collateral margin netting efficiencies at Calpine.
(2) | Revenues relating to contracts accounted for as leases and derivatives include energy and capacity revenues relating to PPAs that we are required to account for as operating leases and physical and financial commodity derivative contracts, primarily relating to power, natural gas and environmental products. Revenue related to derivative instruments includes revenue recorded in Commodity revenue and mark-to-market gain (loss) within our operating revenues on our Consolidated Condensed Statements of Operations.
Performance Obligations and Contract Balances At March 31, 2019 and December 31, 2018, deferred revenue balances relating to contracts with our customers were included in other current liabilities on our Consolidated Condensed Balance Sheets and primarily relate to sales of environmental products and capacity. We classify deferred revenue as current or long-term based on the timing of when we expect to recognize revenue. The balance outstanding at March 31, 2019 and December 31, 2018 was $19 million and $14 million, respectively. The revenue recognized during the three months ended March 31, 2019 and 2018, relating to the deferred revenue balance at the beginning of each period was $2 million and $5 million, respectively, and resulted from our performance under the customer contracts. The change in the deferred revenue balance during the three months ended March 31, 2019 and 2018 was primarily due to the timing difference of when consideration was received and when the related good or service was transferred. Performance Obligations not yet Satisfied As of March 31, 2019, we have entered into certain contracts for fixed and determinable amounts with customers under which we have not yet completed our performance obligations which primarily includes agreements for which we are providing capacity from our generating facilities. We have revenues related to the sale of capacity through participation in various ISO capacity auctions estimated based upon cleared volumes and the sale of capacity to our customers of $430 million, $492 million, $441 million, $223 million and $47 million that will be recognized during the years ending December 31, 2019, 2020, 2021, 2022 and 2023, respectively, and $25 million thereafter. Revenues under these contracts will be recognized as we transfer control of the commodities to our customers.
