From Small Beginnings to Hawaii's Most Complete Energy Company

In 1993, Bruce Ekimura founded Alternate Energy Hawaii with a simple belief: Hawaii families deserve reliable, affordable energy solutions delivered by people who live and work in the same community.

What started as a small electrical contracting operation in Pearl City has grown into Hawaii's most comprehensive energy services provider. Over three decades, we've installed more than 59 megawatts of solar power across 10,000+ homes — while expanding into battery storage, air conditioning, solar hot water, EV charging, roofing, and general electrical services.

Through it all, one thing hasn't changed: every installer is our employee. We don't subcontract. We don't cut corners. We show up, do it right, and stand behind our work.

Part of the Community

We're not just a business in Hawaii — we're part of the community. Our team lives in the neighborhoods we serve, our kids go to the same schools, and we care about the same future. We support local causes, hire locally, and believe in giving back to the islands that have given us so much over 33 years.

Hawaii has set a bold goal: 100% renewable energy by 2045. We're proud to be a part of that mission, one rooftop at a time.
