A Clean Energy Project

Kūpono Solar is proposed for development by Bright Canyon Energy, which would construct, own and operate 42 MW of clean, renewable solar energy. The project would connect to Hawaiian Electric Company’s Oʻahu grid for 20 years. When complete, the project’s renewable energy will supply power to Oʻahu’s local grid, powering 10,000 homes, reducing more than 50,000 tons of carbon dioxide annually from Hawaiʻi’s environment – equivalent to offsetting carbon dioxide emissions from 12,000 cars every year.

Project Details

  • 42 MW of photovoltaic solar array technology mounted on a low-profile tracking system and 42 MW/168 MWh (four-hour duration) of lithium-ion batteries housed in a state-of-the-art containment system that includes around-the-clock monitoring, cooling and fire suppression systems
  • The project site would also have structures to house the controls for system and maintenance

The proposed project would be secured by fences in compliance with Department of Navy standards and meet all permitting requirements.

Location

Kūpono Solar is proposed for construction on approximately 160 acres of underutilized lands within the Navy West Loch Annex of Joint Base Pearl Harbor-Hickam. This proposed site is subject to an anticipated competitive solicitation by the Department of the Navy. Site boundaries and design are preliminary and subject to change.
