An electricity consumption agreement (ECA) is a legal-grade contract between an electricity producer (supplier) and a pantograph (buyer, service provider or large distributor). The duration of the contract can range from 5 to 20 years during which the electricity buyer snows energy and, sometimes, the capacity and/or ancillary services of the electricity producer. These agreements play a key role in the financing of independent (i.e. non-distribution) power generation facilities. The seller under the PPA is usually an independent power producer or „PPI“. Under a ECA, the buyer is usually a distribution company or a company that purchases electricity to meet the needs of its customers. In the case of distributed generation with a commercial AA variant, the buyer can be the occupant of the building – for example, a company, a school or a government. Electricity distributors may also enter into ECA with the seller. While BDP transactions can be attractive to both municipalities and bank buyers, they can have many special considerations that are beyond the scope of this article. The ECA is deemed contractually binding on the date of its signature, also known as the effective date. Once the project is built, the effective date ensures that the buyer buys the off electricity and that the supplier does not sell its generation to anyone other than the buyer.  A bond purchase agreement (EPS) is a contract that contains certain clauses that are executed on the valuation date of the new bond issue. The terms of an EPS are as follows: an EPS is similar to a Bond Indenture (or Trust Indenture), as they are both contracts concluded between an issuer and a company under the terms of a loan.
While an EPS is an agreement between the issuer and the songwriter of the new issue, indenture is a contract between the issuer and the agent representing the interests of bond investors. A bond purchase agreement (EPS) is a legally binding document between a bond issuer and a sub-author that sets the terms for a bond sale. The terms of a bond purchase contract include, inter alia, terms of sale such as the sale price, borrowing rate, bond maturity, provisions for repayment of bonds, provisions for declining funds and the conditions under which the contract may be terminated. . . .
