The Ameresco Kūpono Project is the largest solar-plus-battery energy storage system (BESS) on Oʻahu, providing 42 MW of PV capacity and 168 MWh of storage to serve approximately 10,000 homes.

Ameresco, Inc., (NYSE: AMRC), a leading energy solutions provider dedicated to helping customers navigate the energy transition, today announced it has been named to Fortune’s 2025 “Change the World” list, recognizing companies that deliver measurable social and environmental impact.  Ameresco earned this honor for the Kūpono Project on O‘ahu, Hawai‘i, the island’s largest solar-plus-battery storage facility.

The Kūpono Project powers approximately 10,000 homes and offsets over 50,000 tons of carbon emissions annually. Supporting energy security and independence, in line with the Department of Defense’s (DoD) long-term energy security initiative, by reducing sole reliance on the grid, the project’s distributed energy resource (DER) solution combines a 42‑megawatt (MW) solar photovoltaic array with a 168 megawatt‑hour (MWh) battery energy storage system (BESS), delivering reliable, resilient, and cost-effective energy to the island’s grid.

Ameresco was selected from a shortlist of 250 companies for its leadership in protecting the environment, empowering local communities, and supporting Hawai‘i’s goal of 100% renewable energy by 2045. The project also creates local jobs, supports STEM education, and strengthens energy security for the region.

“Ameresco is honored to be recognized on Fortune’s “Change the World” list for our Kūpono Project,” said Nicole Bulgarino, President of Utility Infrastructure, Ameresco. “This award emphasizes the measurable, tangible impact our team is having on developing innovative energy resiliency solutions through collaboration with our partners and communities.”
