Growing Renewable Energy to Improve the Economy & Environment

MAREC Action is a coalition of utility-scale solar, wind, and battery storage developers, wind turbine and solar panel manufacturers, and public interest organizations dedicated to promoting the growth and development of renewable energy in the Mid-Atlantic region. We offer expert guidance and advocacy on policy and regulatory issues, as well as a unified voice for the industry. Members of MAREC Action value a voice and seat at the table in industry discussions.

Our History


The Mid-Atlantic Renewable Energy Coalition (MAREC) was formed in September 2009 as a nonprofit Pennsylvania corporation.  Currently our membership consists of wind developers, solar developers, wind turbine manufacturers and nonprofit organizations dedicated to the growth of renewable energy technologies to improve our environment, diversify our electric generation portfolio, and boost economic development in the region.  Our mission is to improve and enhance the opportunities for renewable energy development in ten of the jurisdictions in the PJM region in and around the Mid-Atlantic, which include:  Delaware, District of Columbia, Kentucky, Maryland, New Jersey, North Carolina, Ohio, Pennsylvania, Virginia, and West Virginia.  The primary areas of focus of MAREC Action are to provide education and expertise on the environmental sustainability of wind and solar energy; offer technical expertise and advice to assist in understanding the operating and environmental impacts of integrating wind and solar into the electrical power system; and promote fair policies, rules and regulations to expand the region’s electric transmission system to accommodate the growth of renewable energy generation.
