An AAE can bring your business closer to carbon neutrality by reducing Scope 2 emissions (emissions from energy purchases). The buyer generally requires the seller to guarantee that the project meets certain performance standards. Performance guarantees allow the buyer to plan accordingly when developing new facilities or when executing application plans, which also encourages the seller to keep appropriate records. In cases where the supplier`s delivery does not meet the buyer`s contractual energy needs, the seller is responsible for restructuring the buyer`s debt. Other guarantees can be contractually agreed, including availability guarantees and performance curves. Both types of safeguards are more applicable in regions where the energy used by renewable technologies is more volatile.  Physical PPPs refer to the purchase of energy at the point of counting (the receiving point of production). Typically, a distribution company provides energy to its many customers via existing transmission lines. A physical PPA customer receives physical delivery (or property) of energy on the grid. 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.
PPAs offer a way to avoid the capital costs of using the installation of a photovoltaic installation and simplify the process for the host customer. However, in some countries, the AAE model faces regulatory and legislative challenges that would regulate developers as electricity suppliers. A solar rental is another form of third-party financing, very similar to an AAE, but does not involve the sale of electricity. Instead, customers beenied the system like a car. In both cases, the system is owned by a third party, while the host customer receives Solar benefits with little or no prior fees.
