Although PPAs now guarantee the future purchase and sale of energy at an agreed price, the sale of an energy asset still needs to be managed throughout its lifespan. Although the parties may agree and sign a PPP contract for a period of 10 years, the asset concerned may continue to exist for up to 30 years. A POWER Purchase Agreement is a legal contract between an electricity producer (supplier) and an electricity buyer (buyer, usually an electricity supplier or a large electricity buyer/distributor). Contractual terms can take between 5 and 20 years during which the buyer buys energy and sometimes also capacity and/or ancillary services from the electricity producer. These agreements play a key role in financing assets of own property producing electricity (i.e. not held by a utility company). The seller under the AAE is usually an independent electricity producer or a “PPI.” A Power Purchase Agreement is a kind of TPO (Third Part Ownership) financing model in which there is a bipartisan contract. The system is not owned by the owner, but the electricity is purchased at a fixed price by the solar company that owns the system. If this is not the case, we should consider a long-term contract setting out all the terms of the agreement.
Long-term cfDs are mainly used in the electricity market: in some countries, these contracts must be used instead of an AAE (see below), because all the electricity produced must be sold in the country`s electric pool and not to end-users. AAEs are often seen as a central document in the development of independent power generation units (power plants). Because it defines the revenue conditions for the project and the quality of the credit, it is essential for obtaining project financing without recourse. Profile risk arises from the fluctuating nature of renewable energy (for example.B. does not produce solar energy at night). In markets with high penetration of renewable energy, periods of high production can lead to a significant decrease in the price of electricity, i.e. turnover. In order to obtain offers to purchase, the owner of the renewable project usually makes a request for a proposal or offer (RFP/RFQ). Interested energy buyers can then make an offer to purchase. Data center owners Amazon, Google and Microsoft have used PPAs to offset emissions and electricity consumption from cloud computing.
Some manufacturers with high carbon footprints and energy consumption, such as Anheuser-Busch InBev, have also shown interest in PPAs. In 2017, Anheuser-Busch InBev agreed to purchase 220 MW of new wind farms in Mexico through an AEA from energy supplier Iberdrola.  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”). The electricity distributor can continue to supply electricity to an electricity consumer (transform it again into a “corporate PPA”) or to negotiate electricity on an electricity exchange. Many international groups are already buying shares in their electricity consumption via AAAs or have announced their intention to do so more frequently (see there100.org/re100). They use AAEs to obtain stable and predictable electricity prices. AAEs are an effective way to reduce the risk of electricity prices, particularly for operators of high-investment and low-cost facilities (such as photovoltaic and wind power plants). Since electricity payments are already insured to some extent, facility managers and financial banks may be more confident that revenues from the sale of electricity will effectively cover investment costs. This makes the project more cost-effective in the long run. Electricity prices can vary widely and often.
