This paper studies a long-term power purchase agreement (PPA) between a firm and a new renewable energy generator. At each time, the firm must meet an uncertain electricity demand in excess of its existing energy sources. The wholesale electricity market price evolves as a stochastic process. When the firm signs a PPA, a new renewable energy facility becomes operational, and the firm owns the facility\u2019s output during the contract. The new facility\u2019s capacity is determined based on PPA terms. The firm dynamically decides when to start a renewable PPA and total payment to the renewable energy generator to maximize its expected total discounted benefit. We show that the firm\u2019s optimal time-to-sign a PPA is determined by a (time- varying) threshold policy. Our analysis offers key insights to policymakers and renewable energy developers. We find that, in contrast to the common understanding, increasing investment cost for renewable technology can boost renewable energy capacity and output when renewable energy facilities are developed under a PPA. This calls for caution in implementing investment tax credit for clean technologies under PPAs. We show that total renewable energy generation can decrease with site productivity. Hence, restricting renewable facility development to the most productive sites might be counterproductive under PPAs.<\/p>\n
