Puʻuloa Solar

We Believe

The Project is rooted in its intent and relationship with the community.


Located in a mixed-use area of Joint Base Pearl Harbor-Hickam (JBPHH), the proposed project would deliver 6 megawatts (MW) of solar photovoltaic and 6 MW / 30 megawatt hours (MWH) of energy storage to provide solar after sunset and more clean, renewable energy to Hawaiian Electric Company’s Oʻahu grid. 

The Project will be connected to Hawaiian Electric’s 46kV feeders located near the Project site. Due to National security, the on-site electrical interconnection route will not be made public.

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 respond to the variability of solar generation, filling in the gaps to enhance reliability.

The Project can provide renewable energy day or night, help stabilize energy fuel costs and provide a pathway to increased energy independence.

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

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

Benefiting The Wider Community

Economic Boost

The stable cost of energy will be passed on to Oʻahu utility customers.

Solar After Sunset

Battery storage would enable renewable energy to be dispatched when needed most. 


Employment & Community Benefits

The Project will provide local prevailing wage jobs in construction, other local Project-related jobs and apprenticeships, and ongoing operational employment, as well as maximize spending within local communities to support small and under-represented businesses.

Ameresco is committed to identifying, through stakeholder input, impactful ways to benefit the local community with support to entities such as community organizations, social service providers, and non-profits focused on environment, natural hazard mitigation, quality-of-life enhancements, homelessness, Science Technology Engineering and Math (STEM) education, and youth recreation. The Project is committed to providing a package of $18,000 annual benefits to the community through a local non-profit administrator throughout the life of the Project.
