Nearly half the power at the National Aquarium in Baltimore will soon come from a solar grid on the Eastern Shore.
The aquarium has signed a 25-year electricity supply agreement with Constellation Energy Group to buy a portion of its electricity from a new solar power plant in Cambridge.
Under the agreement, Constellation will fund and construct a 4.3-megawatt solar grid on about 22 acres in Cambridge. The system is being developed with the solar firm OneEnergy Renewables and is scheduled to be complete in March.
When it opens, theF solar project will generate an estimated 5.8 million kilowatt hours in its first year. That’s more than 40 percent of the aquarium’s annual energy needs.
“This agreement with Constellation allows us to ‘walk our talk’ as a conservation organization,” John Racanelli, CEO of the National Aquarium, said in a statement. “Now, a significant percent of our electricity will come from clean, renewable energy. We hope this will help set a precedent for supporting large-scale, off-site projects and inspire others to take action.”
