Like a PPA, an efficiency services agreement enables third-party ownership of a project, in which a developer designs, finances, implements, and owns a package of energy and water efficiency measures at a customer facility. In return for implementing the project, the ESA provider charges the customer for any realized savings, at a rate that is less than their current cost of electricity, gas, or water. This continues until the end of the contract period, typically 10 years, upon which time the customer can renew the contract or purchase the equipment at fair market value. Read More
