It`s not the final price you`ll see on your bills each month – it`s simply the price you pay for the share of renewable energy you`ve committed to. Your “supply balance sheet,” as you hedge it and at what rate, will also feed into the final price you see on your monthly bill. To receive offers to purchase, the owner of the renewable project usually goes through a request for a quote or quote (RFP/RFQ). Interested energy buyers can then submit an offer to purchase. Data center owners Amazon, Google, and Microsoft have used PPAs to offset emissions and energy consumption from cloud computing. Some manufacturers with high CO₂ emissions and energy consumption, such as Anheuser-Busch InBev, have also shown interest in ESAs. In 2017, Anheuser-Busch InBev agreed to acquire 220 MW of new wind power with a PPA from energy provider Iberdrola in Mexico.  A power purchase agreement (ECA) or electricity contract is a contract between two parties, one of whom produces electricity (the seller) and the other who wants to purchase electricity (the buyer). The ECA sets out all commercial terms for the sale of electricity between the two parties, including when the project will begin business operations, the schedule for the supply of electricity, penalties for delivery, terms of payment and termination.
A ECA is the main agreement that defines the revenue and credit quality of a generating project and is therefore a key project financing instrument. . . .
