The developer of Hawaii’s largest solar farm said it has begun pumping power into the grid.

San Diego-based, Eurus Energy America Corp. said today its 27.6-megawatt solar photovoltaic facility – with the potential capacity to power more than 4,000 homes — called EE Waianae Solar Project LLC has begun commercial operation.

Eurus will sell energy to HECO at a rate of about 14.5 cents per kilowatt-hour. The facility is jointly owned by affiliates of Eurus and Toyota Tsusho America Inc.

Satoshi Takahata, president and CEO of Eurus Energy America, said in a statement he wants to help Hawaii reach its goal of 100 percent electricity production from renewable energy by 2045.

“Eurus is committed to bringing highly viable renewable energy projects online in a responsible and timely manner to help the state of Hawaii meet its ambitious renewable energy goals” he said.

The solar project in Waianae will triple the amount of utility-scale solar connected to Oahu’s grid.

HECO has said solar farms cost less and are easier to manage than 10,000 separate private systems.

There are three other solar facilities on Oahu, Kalaeloa Solar Two with 5 megawatts, Kalaeloa Renewable Energy Park with 5 megawatts and Kapolei Sustainable Energy Park with 1 megawatt. One megawatt of solar photovoltaic powers on average 164 homes, according the Solar Energy Industries Association.

The second largest solar arrays are on Kauai. Kauai Island Utility Cooperative has two 12-megawatt arrays. The Koloa array went online in August 2014. The Anahola array was completed in summer 2015.
