Maui's $241M Solar Project Could Power 18,000 Homes by 2028

Maui is about to get a whole lot sunnier when it comes to energy costs.

The Kūihelani Solar Phase 2 project, a $241 million renewable energy facility, won unanimous approval from the Maui Planning Commission this week. If completed by 2028, it will power roughly 18,425 homes for at least two decades at a fixed price, protecting residents from the wild swings in fossil fuel costs that currently plague their electric bills.

Hawaii residents pay the highest electricity rates in the country at 43 cents per kilowatt hour. This new solar facility aims to change that equation.

The project comes with a 20-year locked rate of about 15 cents per kilowatt hour. That's significantly lower than current rates and offers something even more valuable: stability in a world where oil prices jump with every global conflict.

AES Hawaii is racing against the clock to build the facility. The company needs to complete construction by the end of 2028 to qualify for federal tax credits that make the entire project financially viable. One more permit from the state Land Use Commission stands between the solar farm and breaking ground.

The timing couldn't be better for Maui's aging power infrastructure. Central Maui's fossil fuel plants are approaching decommissioning, and the island needs clean energy sources to fill that gap while working toward Hawaii's ambitious goal of 100% renewable electricity by 2045.

Construction workers and union representatives packed the commission meeting to voice support. The project promises 1,541 good-paying jobs and $90 million in labor income flowing into the community.

The Ripple Effect

This isn't AES Hawaii's first rodeo on Maui. The company successfully launched Kūihelani Solar Phase 1 two years ago, which now supplies about 15% of the island's electricity. That track record gave officials confidence to back this expansion.

The Phase 2 facility will be slightly smaller, featuring a 40-megawatt solar system with 107,000 solar panels and battery storage capable of holding 160 megawatt hours. Those batteries are the secret weapon against evening power demands.

When families come home and flip on appliances, electricity demand spikes. Right now, dirty fossil fuel plants fire up to meet that need. With this project's batteries, stored solar energy can discharge instead, keeping the lights on with clean power.

The facility will connect directly to Maui Electric Company's islandwide grid. Combined with Phase 1, these solar projects would supply nearly a quarter of Maui County's electricity from the sun.

As Maui continues recovering and rebuilding, this kind of energy independence matters more than ever.
