Stephen Mushegan

Stephen is a former Manager on the Carbon-Free Building program, overseeing engagement with policymakers, NGOs, utilities, and other stakeholders in Eastern US states and cities to electrify heating, hot water, and cooking to reduce fossil fuel combustion in buildings. In this role, he supported partners advocating for policy changes to enable building electrification at scale by providing analysis and disseminating facts around the economic, carbon, health, and air quality benefits of moving to an all-electric future.


Previously, Stephen was a Project Portfolio Manager for the Islands Energy Program, where he oversaw and advised renewable energy, energy storage, and microgrid project development and implementation in Caribbean small island nations.

He joined RMI from the Clinton Foundation, where he led the Clinton Climate Initiative’s technical team of project managers and analysts advising small island governments and utilities in renewable energy initiatives. One of his key achievements in this role was overseeing the procurement and contract negotiations for Saint Lucia’s first utility-scale renewable energy project, the La Tourney 3 MW solar farm. Working closely with RMI, Stephen also supported the development of 1 MW of distributed utility-owned solar PV in Turks and Caicos Islands, and provided techno-economic analysis for energy transition plans in Saint Lucia and Belize. In partnership with NREL, he led a post-hurricane energy transition plan in Dominica.

Prior to this, Stephen held several project management and energy engineering roles specializing in the feasibility, design, and turn-key implementation of combined heat and power, heat recovery, and electrical energy efficiency projects, particularly in the commercial and industrial sector.
