In 2017, Vattenfall and Microsoft signed a 10-year power purchase agreement in which the Wieringermeer wind farm will operate Microsoft`s nearby data center. In the case of decentralized production (where the generator is on a construction site and the energy is sold to the building occupants), commercial PPAs have developed as a variant allowing companies, schools and governments to source directly from the generator and not from the distribution company. This approach facilitates the financing of distribution-related production facilities, such as photovoltaics, micro-turbines, alternative piston engines and fuel cells. An electricity supply contract is a long-term electricity supply contract between an operator (seller) and an electricity customer (buyer). The buyer can be an intermediary or an energy supplier or a large direct industrial consumer such as a computer company that needs renewable energy for its computing centers. Agreements are usually signed for up to 10 years, but short-term AAEs are also possible. For future AAEs, a basic PPP base has been developed between the Bonneville Power Administration and a wind power generation unit.  Solar PPAs is now being successfully used in the California Solar Initiative`s Multifamily Affordable Solar Housing (MASH) program.  This aspect of the success of the CSI program has only recently been opened up to applications.
According to BloombergNEF`s latest Corporate Energy Market Outlook, companies around the world purchased a record amount of clean energy through PPAs in 2019. In total, approximately 19.5 gigawatts (GW) have been signed for renewable energy contracts between more than 100 companies in 23 different countries. 13.6 GW were signed in the United States and 2.6 GW in Europe, the Middle East and Africa.

Under an AAE, the buyer is usually a utility company or a company that buys electricity to meet the needs of its customers. With the production distributed with a commercial variant of PPA, the buyer can be the occupant of the building – for example. B a business, a school or a government. Electricity distributors can also enter into AAEs with the seller.

Consumers, particularly large industrial enterprises, are also increasingly aware of the benefits of generating electricity from renewable energy sources. By entering into a long-term sales contract, they protect themselves against price fluctuations in electricity markets. This will allow them to control their costs and contribute to the energy transition. On the other hand, companies are increasingly looking for energy solutions to achieve their ambitious sustainable development goals and are increasingly demanding a direct supply of green electricity. Nearly half of the Fortune 500 companies had already set climate targets by 2017. While these are mainly global IT companies with high energy needs such as Facebook and Microsoft, all sectors are becoming increasingly interested. The renewable energy generator receives a fixed price per megawatt-hour, which means it can expect fixed returns for its investment and provide the bank with the security it needs for loans. This allows the high-demand customer to ensure that their renewable energy supply comes directly from a given facility or a green portfolio at a fixed price for the duration of the agreement. Proof of green quality and the origin of energy supply is provided by the original guarantees (GO) of energy-producing facilities
