Hawaiian Electric has applied to the Hawaii Public Utilities Commission for a 20-year power purchase agreement with Pulehu Solar, which would add 20 megawatts of solar and 80 megawatt-hours of battery storage to Maui’s grid. The project, sited on Haleakala Ranch land, would generate enough clean energy to power roughly 10,000 Maui households.
- Hawaiian Electric filed for PUC approval of a 20-year fixed-price deal with Pulehu Solar to bring new renewable capacity to Maui’s grid.
- The project includes 20MW of solar generation plus an 80MWh battery system capable of dispatching stored energy during high-demand evening hours.
- Hawaiian Electric’s RDG model gives the utility direct control over when stored energy is released, improving grid reliability and flexibility.
- Project design was modified after community input to move battery storage and substation farther from residences and to strengthen wildfire protection measures.
- Commercial operation is contingent on PUC approval followed by final permitting, financing, and construction — no timeline for completion was specified.
