A multi-technology AAE covers several projects of different technologies (such as wind, solar, biomass, geothermal or hydropower). The aim of this document is to support continuous innovation in the way companies buy renewable energy for their activities. Virtual/synthetic PPPs – Another type of CPPA is a “virtual PPP” (also called VPPA or “synthetic PPPA”) that is similar to a CPPA in structure, but has fundamental differences. First, there is no physical supply of energy to the customer; On the contrary, the electricity produced by the green energy producer is sold on the wholesale market. Second, the customer acquires the UCs related to such a sale, even if he does not receive the energy directly. Third, the alternator and the customer act on financial transactions during the “swap” on the basis of the difference between a fixed price of electricity (as if the customer had purchased the service) and the variable spot market price. The commonality between a CPPA and the VPPA is that electricity is generated from renewable sources, that the customer receives the UCs and that the end result gives long-term price stability for electricity.  An AAE is a contract between the buyer (buyer) and the electricity producer (developer, independent electricity producer, investor) for the purchase of electricity at pre-agreed prices for pre-agreed periods. The contract contains the terms and conditions of electricity sales: length, delivery point/date, volume and price. Electricity can be supplied by renewable energy or construction projects. The company is generally required to: pay a premium to the distribution company to provide the risk of intermittency (to provide electricity when the generator does not produce electricity (renewable energy is intermittent) of the company, to add a basic charge in its supply contract that compromise the compensation of the agreement and the increase of renewable electricity (if necessary with a supplement – if the generator is not produced) to cover the energy needs of the company. Energy efficiency – companies can take energy efficiency measures, such as upgrading windows and insulation.
B, installing more efficient lighting and equipment, installing motion sensors and other devices that shut down devices or equipment when not in use, and installing systems to use advanced energy instead of more expensive advanced energy. The requirement for a compatible supply agreement between licensed suppliers – It is essential to find the right electricity supplier to arrange direct delivery agreements between low-carbon generators and businesses. Such supplier partners can often provide the company`s lack of know-how, such as Z.B. Management, demand and supply compensation, Grid System Operator Liaison.
