Energy and Infrastructure

Harnessing nature’s power to energize communities

For centuries, our people have thrived in harmony with the forces of nature. Today, CIRI employs the latest technologies and finance strategies to harness the power of renewable energy in Alaska and the Lower 48. Our energy projects create jobs and economic activity while generating profits for shareholders and business partners.

Fire Island Wind

Wind power to energize Southcentral Alaska

Located in Cook Inlet, approximately three miles offshore from Anchorage, Fire Island is home to CIRI’s Fire Island Wind project, the first wind-powered energy initiative to supply electricity to Alaska’s largest city.

Fire Island Wind is a testament to CIRI’s ability to develop, manage and operate large-scale projects on time and on budget. Collaboration with nearly 100 local businesses during development and construction brought about an independent power producer that delivers electricity to 6,500 Alaskan homes and benefits shareholders, business partners and regional economies.
