The European Federation of Energy Traders is an association that defends policies and regulations on the electricity and gas trade in Europe. It was created in 1999 to support the liberalisation of Europe`s electricity and gas markets. 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.  An AAE is a contractual agreement to purchase an amount of energy at an agreed price, for a specified period of time, prior to energy production. This relates to the difference between what was planned (usually a day before) and actual production (the cost of imbalance). This risk can be reduced by correcting the costs of imbalance through an agreement or intraday trade, if available.
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). Kenya – Electricity Purchase Contract (AAE) – Simplified agreement for Kenya A relatively simplified electricity purchase agreement has been developed for Kenya`s electricity regulator for use in “Hydro, Geothermal or Gas” electricity generation facilities. It expects a capacity load and an energy load. The seller must sell all the net electrical power of the installation to the buyer. The Energy Regulatory Commission also provides a link to a PPP model for large renewable generators over 10 MW and an AAE for smaller renewable energy projects of less than 10 MW on its renewable energy portal. 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. Process installation projects (see point 2.5.1) for which a product is sold, such as the aerating contract.
B, are usually done on a take-or-pay basis.
