OneEnergy Renewables and Constellation developed a 4.3-MW solar electric project located on the Eastern Shore of Maryland. The off-site system, which is part of an electricity supply agreement between Constellation and the National Aquarium, will provide power for approximately 40 percent of the Aquarium's electricity requirements for the next 25 years. OneEnergy's Purpose-Built Solar program, which connects large electricity users with custom-built, off-site solar projects, will enable the National Aquarium to procure power from Constellation at a fixed price equal to the amount of power generated by the solar facility. Constellation will finance, build, and own the system.
