Sempra U.S. Gas & Power and BP Wind Energy recently announced the full commercial operation of the 21 mW Auwahi Wind facility. The power project includes eight new wind turbines on the southeast ridge of Haleakala.
"We are very pleased to complete construction of Auwahi Wind both on time and on budget," said Jeffrey W. Martin, president and CEO of Sempra U.S. Gas & Power. "The addition of new, clean energy from our project will be a boost for Maui's infrastructure and will help Hawai'i achieve its goal of securing 40 percent of its energy from renewable sources by 2030. This project could not have been built without the enthusiastic support of the local community, the 'Ulupalakua Ranch and neighbors who recognize the importance of sustainable energy."
Power from Auwahi Wind has been sold to Maui Electric Company (MECO) under a 20-year contract. The turbines will generate enough clean electricity to power about 10,000 typical Maui homes. An important component of the project is a 10 mW battery capable of storing 4.4 mW-hours of power. Energy from the battery will help regulate and sustain power to the MECO grid during light wind conditions.
The newly completed Auwahi Wind project is located on the southeast ridge of Haleakalā volcano on ‘Ulupalakua Ranch lands.
"Innovation is a big part of what Sempra U.S. Gas & Power brings to all of our projects," Martin said. "The battery storage component of Auwahi Wind includes state-of-the-art monitoring and safety controls which will help maximize the benefit that MECO and its customers receive from this project."
Construction of the wind farm on 'Ulupalakua Ranch began in March 2012, and involved more than 180 workers. Auwahi Wind will employ four full-time employees.
"It was just seven months ago that the groundbreaking for Auwahi Wind was held and today we're celebrating its completion," said newly appointed U.S. Senator Brian Schatz. "What a great way to end a banner year for wind energy in Hawai'i. This project is an important step toward energy self-sufficiency and has the added benefit of helping 'Ulupalakua remain financially viable and preserve a ranching lifestyle on Maui and protect open space and habitat for native plants and animals."
"BP and Sempra U.S. Gas & Power have been terrific partners," said Sumner Erdman, president of 'Ulupalakua Ranch. "The Auwahi project protects the environment, maximizes wind as a renewable energy resource, and allows us to maintain the rural open space and grazing areas necessary for us to raise our cattle."
