When did geothermal energy become commercially available in Hawaii?
The Puna Geothermal Venture facility is the first and only commercial scale geothermal plant in Hawaii. It produces about 30 MW of power, or 20 percent of the island’s needs. That’s enough electricity for 30,000 residents and visitors. Today PGV saves HELCO more than 400,000 barrels of oil a year.
