  • What We Do

    The Clean Power team brokers and co-develops sustainable energy globally - primarily wind and solar. We make capital introductions to financiers and funds for project developers. We have a network of industry insiders and innovators who have identified potential renewable energy opportunities around the globe, built through our experience as developers.

    What makes us unique is we screen projects that meet our high standards of: feasibility, profitability, and expectations of success before we bring anything to the market. By the time we present the projects to our buyer and investor network, the sale is imminent to any qualified party.

  • Our Team

    Mary O'Donnell


    O’Donnell began her career in the energy industry three decades ago when she purchased a 105 acre sand and gravel pit in Kingston, Massachusetts. After an extensive study, Mary abandoned plans to re-develop the site into a waste-to-energy facility, but her foray into the industry had begun.


    Mary is the founder of O’Donnell Sand and Gravel, the largest woman owned business to supply the “Big Dig”. Annual revenues at that time approached $17MM and the Company employed approximately 60 people. O’Donnell Sand & Gravel provided all the stone and gravel for the third harbor tunnel ($11MM contract) and processed all the stone and glacial rock from Spectacle Island for the MWRA ($12MM contract).


    In 2010, after a developer’s quest to create a transit oriented 40R development on the site collapsed under the weight of the a troubled economy, Mary resumed her mission to develop energy on the site after learning the Town of Kingston had conducted a successful three year wind feasibility study on municipal land that directly abutted her 105 acre site. Kingston Wind, No Fossil Fuel’s 6MW flagship renewable farm, was commissioned on January 20th, 2012.


    Mary founded two solar development companies and went on to develop No Fossil Fuel Marshfield Solar, a 4 MW solar facility commercially operational since 2013. The project was sold to Washington Gas and Energy Systems. The project was built on a private capped landfill, and the power sold locally to the Town of Marshfield.


    In addition to No Fossil Fuel Marshfield Solar, Mary co-founded No Fossil Fuel Dartmouth Solar, a 6 MW solar facility commercially operational since 2014. The project has off-take agreements with Silver Lake Regional School District, and the Town of Carver. The project was constructed on the site of a cranberry bog.


    Mary is politically active, and engages in renewable energy policy and regulatory rulemaking proceedings, as well as partner with universities to educate next generation of renewable energy leaders. Mary is certified WBE as a renewable energy developer by the Supplier Diversity Office of the Commonwealth of Massachusetts. She serves on the board of directors for Southeast Regional Network, and Kingston Business Association.

    Michael Frenette


    Michael graduated from George Washington University in 2006 with a B.A. in International Affairs with a concentration in International Economics.

As a Senior Analyst at US Bank, Frenette spent his weeknights and weekends working as the controller for No Fossil Fuel, and was instrumental in preparing the costs and coordinating 1603 Cash Grant application. Frenette leveraged his experience in operations, compliance and financial reporting from the banking sector and left in May 2012 to become the CFO of No Fossil Fuel.

    Frenette has successfully closed over $20 MM in term financing and project finance under his tenure at No Fossil Fuel. In addition to his role as CFO, he functions as a project manager, and lead the acquisition, design, permitting, and sale of the 650 kW PV project in Wilbraham, MA. Frenette is responsible for the asset management of No Fossil Fuel’s 6 MW wind farm.

For CPI, Mr. Ernst has helped conduct due diligence and broker several solar and wind farms in the Dominican Republic, Kazakhstan, Sub-Saharan Africa, and Philippines. He has met with government and transmission officials in the Dominican Republic and the Philippines, where he drafted documents to acquire and maintain rights to two 48-MW solar photovoltaic farms for CPI.

    At Tetra Tech, Mr. Ernst supported the siting and permitting of offshore wind parks and submarine cables off ten states from Maine to Virginia and in the Great Lakes and Hawaii, including the first offshore wind farm in the U.S. off Block Island, RI. Before joining Tetra Tech, Mr. Ernst served as Vice President of a transmission development company that built submarine cables including the high voltage direct current Cross Sound Cable from New Haven, CT, to Long Island, NY.

    Mr. Ernst was General Counsel and Legislative Director of the Massachusetts Department of Public Utilities during electric industry restructuring and a Hearing Officer for the Massachusetts Energy Facilities Siting Board for new power plants and transmission lines. He also served as Counsel to the Joint Committee on Energy of the Massachusetts Legislature for six years and clean energy advocate for Union of Concerned Scientists and MassPIRG.
