DEEP: Deputy Commisisoner Mary Sotos

Mary Sotos
Deputy Commissioner – Energy

{Deputy Commissioner Mary Sotos} Mary Sotos is the Deputy Commissioner for Energy at the Connecticut Department of Energy and Environmental Protection (DEEP).  She was appointed to this position in February, 2017.
As the Energy Deputy, Mary is responsible for the development and implementation of energy policies designed to bring cheaper, cleaner, and more reliable power to Connecticut’s families and businesses – and integrating these efforts with a 21st century approach to regulating and directing the state’s electric, natural gas, and water utilities.
Before joining DEEP, Mary served as the Policy Lead for the U.S. Energy Program at World Resources Institute (WRI), a highly respected Washington D.C.-based non-profit organization. Mary provided technical guidance to states designing and implementing new clean energy standards and emission reduction policies. She worked with large utilities, state public utility commissions, and Fortune 500 companies to pursue cost-effective business models and utility tariffs for deploying renewables.
During her eight years at WRI, she also led the development of multiple voluntary greenhouse gas measurement and reporting standards as part of WRI’s Greenhouse Gas Protocol program, a partnership with the World Business Council for Sustainable Development. These standards require achieving consensus among cities, federal government agencies, business leaders, and electric utilities. They impact how hundreds of companies and cities measure and manage GHG emissions. For her leadership in developing the standard on electricity emissions accounting, she was awarded the Leader in Green Power Market Development award by the Center for Resource Solutions (2014).
Mary graduated from St. Olaf College in Northfield, Minnesota with a bachelor’s degree in Environmental Studies and a concentration in Social Sciences. On a Fulbright Fellowship, she pursued graduate coursework in Science and Environmental Management at the Université Libre de Bruxelles, in Brussels, Belgium.
