In some countries, air-mining contracts are already being used to finance the construction (investment costs) and operation (operating costs) of renewable energy facilities. Countries that need utilities or want to cover part of their electricity supply from renewable energy sources are particularly attracted to AAEs. The agreements are an alternative for the development of renewable energy in areas where policies are reluctant to promote the development of renewable energy (and subsidies). A power purchase agreement (AAE) provides payment flow for a build-own transfer (BOT) or a concession project for an independent power plant (PPI). It is between the “buyer” buyer (often a state electricity supplier) and a private electricity producer. The AAE described here is not suitable for electricity sold on world markets (see deregulated electricity markets below). This summary focuses on a basic thermal charge facility (the problems would be slightly different for thermal or hydroelectric power plants in the central area or in the state-of-the-art facilities). Pacificorp Power Purchase Contract (AAE) for large power plants (pdf) – Pacificorp`s proposed power purchase contract for power plants with a net capacity of more than 1000 kilowatts – relatively short agreement. Designed in the context of the U.S. regulatory structure. In order to qualify for an AAE, a project must be located in a state or jurisdiction where ownership of a third party of power generation facilities is permitted. Some state rules limit or limit the sale of electricity in regulated markets. For more information on where PPAs are available, see database of State Incentives for Renewable Energy (DSIRE).
The AAE is considered binding at the time of signing, also known as the reference date. Once the project is built, the validity date ensures that the buyer buys the electricity produced and that the supplier does not sell its production to others other than the buyer.  Electricity producers enter into AAEs either bilaterally with a consumer company (“Corporate PPA”) or with an electricity distributor who purchases the electricity generated (“Merchant PPA”).
