After decades of false starts, geothermal power may be coming to Unalaska.
The Ounalashka Corp. and Fairbanks-based Chena Power LLC have formed a company to develop a geothermal project at Makushin Volcano.
At a recent Unalaska City Council meeting, Ounalashka Corp. CEO Chris Salts said the company’s goal is to reduce the city’s consumption of fuel, as well as lower and stabilize utility costs for residents and businesses.
“We don’t intend to replace the city’s utility. We just want to supply power to it,” said Salts. “We plan to eliminate the city’s reliance on fossil fuels to generate electricity and heat.”
This attempt at geothermal energy marks the latest effort in a long history of companies trying to develop the resource about 14 miles from Unalaska’s current power grid. For three decades, the plans of private developers have fallen through, largely due to high startup costs. The last attempt was abandoned in 2015.
Unalaska City Manager Erin Reinders said the city supports the new project. The City Council has also identified alternative energy as one of its federal lobbying priorities.
“The city continues to look for support with reliable and cost-effective alternate energy sources for the community, including geothermal and wind,” said Reinders.
With city backing, Ounalashka and Chena Power are pursuing a U.S. Department of Energy loan worth between $350 million to $500 million.
Salts said that funding would allow the project to move forward at no expense or risk to the city. He also said the company will use existing research performed at Makushin over the last 60 years, meaning further feasibility investigations aren’t necessary.
A test well drilled in the 1980s revealed a hot-water reservoir that could generate at least 12 megawatts of electricity, or enough to heat around 10,000 homes.
Salts said leaders of the new company will attend the City Council’s meeting on Jan. 14. That’s when they’ll ask the city to sign a formal power purchase agreement — a deal that would have the city agree to buy geothermal energy from their operation.
“Once we do have a PPA in place, I think it’s important to point out when we might be enjoying this diesel-free and clean energy,” said Salts. “We would target commercial operations to commence before the end of 2022, if everything works out well.”
The company will present more information on its proposal, including its costs and technical aspects, at the upcoming meeting. Salts said he’s hoping to win a city agreement by the end of January.
