Kūpono Solar

Reflecting the values of decency, reliability, excellence, righteousness and fairness

We Believe

Kūpono is the embodiment of the project — its intent and its relationship with the community

Kūpono Solar

The project is designed to deliver 42 megawatts (MW) of clean, renewable energy to Hawaiian Electric Company’s Oʻahu grid. This photovoltaic (PV) solar project energizes a 42-MW, four-hour battery energy storage system to provide solar after sunset. Kūpono Solar is designed to deliver sustainable, renewable energy to power 10,000 homes on Oʻahu, reducing more than 50,000 tons of carbon dioxide annually from Hawaiʻi’s environment—the equivalent to offsetting emissions from 12,000 cars every year.

Project Benefits

The project will provide clean, renewable energy and help stabilize energy costs, reduce dependence on fossil fuels and provide a pathway to increased energy independence.

Renewable electricity generated by this project will replace energy generated by burning fossil fuel, thereby reducing emissions and greenhouse gases. The batteries will enable renewable energy to be utilized during the peak evening hours.

The project aligns with numerous critical goals and mandates in Hawaiʻi, including:

  • The state’s energy goals of 100% renewable electricity by 2045
  • The state’s carbon-neutral goal by 2045

Benefiting the wider community

Economic Boost

Stable cost of energy would be passed on to Oʻahu utility customers
