Understanding Power Purchase Agreement
An electricity purchase contract (AAE) or an electricity contract is a contract between two parties, one that produces electricity (the seller) and the other that wants to buy electricity (the buyer). The PPP sets out all the terms and conditions for the sale of electricity between the two parties, including when the project will begin operating commercially, electricity delivery schedule, delivery penalties, payment terms and termination. An AEA is the main agreement that defines the revenue and credit quality of a production project and is therefore a key instrument of project financing. There are many forms of PPA in Use Today and they vary according to the needs of the buyer, seller, and financing against the parties.   However, AAEs are complex in terms of structure and pricing. The absence or absence of negotiation of a contractual clause may affect the total revenue of an AEA project. This requires a thorough understanding of energy risks, assessment and negotiation issues. Power Purchase Agreements (PPAs) may be appropriate: Although PPAs 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 life. 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. 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. Negotiating commercial contracts continues to pose a major challenge to companies around the world, even when it comes to technological advances, economic modelling and good legislative practices. In negotiations, each side must strike a balance between defending its own interests and finding common ground. Even after an agreement is reached, the development of a treaty that accurately reflects the broad and nuanced nature of the agreement can still face challenges. Despite his enthusiasm at the beginning of the treaty negotiations, the inability of a party to seek balance and clarity can quickly lead to apathy or, worse, a unilateral agreement doomed to failure. 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. This relates to the difference between what was planned (usually a day before) and actual production (the cost of imbalance).
