For a more detailed analysis of AAE issues of this type, see ifC`s guide to electricity purchase contracts (1996) – see Appendix 2 (page 160) of the World Bank concession toolkit (pdf). 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. The AAE distinguishes where the sale of electricity takes place with respect to the location of the buyer and seller. If electricity is delivered in a “bus bar” sale, the delivery point is on the upper side of the transformer next to the project. In this type of transaction, the buyer is responsible for transferring the seller`s energy. Otherwise, the AAE distinguishes another delivery point contractually agreed by both parties.  The developer sells renewable energy to a final customer through an energy distributor that supplies energy to renewable goods. Any shortfalls are provided from the distributor`s production portfolio. At the end of the month, the customer receives a single bill for all their consumption, whether from the renewable facility under the AAE or at the spot price. 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. With the increase in electricity generation from renewable energy sources, the fall in renewable energy prices and the growing desire for decarbonisation, companies under electricity growth contracts (PPPs) are becoming more frequent. These agreements between an industrial and industrial customer (C-I) and an electricity producer require the purchaser to withdraw all production from a renewable generation asset over an agreed period, the latter depriving the energy retailer.
