Ameresco Begins Construction with Sunel on Sonnedix’s 300MW of Design-Build Solar Park Projects Across the UK

New ground-mounted solar projects designed to generate enough clean energy to power more than 85,000 homes and reduce 58,000 metric tons of carbon dioxide emissions annually.

FRAMINGHAM, MA. AND LONDON, U.K. – December 7, 2023 – Ameresco, Inc. (NYSE: AMRC), a leading cleantech integrator specializing in energy efficiency and renewable energy, and Sunel Group, an international developer and EPC contractor for energy projects, today announced the beginning of construction on a portion of the portfolio of multiple solar PV park projects on behalf of Sonnedix, a global renewable energy producer, across the UK.

The design-build projects will consist of five ground-mounted solar PV parks throughout England designed to generate approximately 300,000 MWh of renewable electricity per year. The parks include Cowley Complex; Gonerby Solar; Winkburn Solar Farm; Gammaton Solar Farm; and Lawns Solar Farm. Once construction is completed, the combined solar parks are anticipated to produce enough clean energy to power 85,000 UK homes and avoid 58,000 metric tons of CO2 emissions annually.

“We are thrilled to partner with Sunel as Sonnedix converts its UK project pipeline to deliver positive clean energy results that will benefit many individuals across the UK,” said Britta MacIntosh, Ameresco’s Executive Vice President and General Manager, West/Europe. “Solar energy solutions are a critical part of the clean energy transition, and we are so happy to work with partners who feel just as passionately about tackling decarbonization goals.”

Sonnedix is the owner of the portfolio and Ameresco Sunel Energy Ltd, a joint venture between Ameresco and Sunel, will serve as the design build partner. The portfolio is already fully contracted under the UK government’s Contracts for Difference (CfD) scheme, which provides a guaranteed price for electricity through 15-year contracts with the Low Carbon Contracts Company.

“It’s a pleasure to work closely again with Ameresco on Sonnedix’s portfolio of solar parks,” said Konstantinos Zygouras, Sunel’s CEO. “Projects like this reignite our passion and dedication to our mission, which is rooted in providing world-class renewable energy projects that support the local communities we serve while making significant improvements that benefit the environment.”

“We are excited to be executing our UK pipeline, contributing to  the UK’s overall supply of clean energy and energy security,” said Axel Thiemann, Sonnedix’s CEO. “Accelerating the energy transition requires action and effort among many groups, and we are delighted to work with Ameresco and Sunel, who we know have a track record of successful clean energy projects.”

Construction on the solar portfolio is expected to reach completion by early 2025.
