Description:
Located in the Puna district on the Big Island in Hawaii, Puna Geothermal Venture (PGV) is the only existing geothermal power plant in Hawaii. PGV is comprised of two air-cooled power plants, a combined cycle system and a binary system, with a total generating capacity of 38 megawatts (MW) and net generating capacity of 34.6 MW according to Hawaii Electric Light Company (HELCO). The facility includes several features to reduce environmental impacts including: noise reduction enclosures a low-profile, small-footprint design, near-zero emissions, 100% geothermal fluid reinjection, and continual monitoring measures. Originally commissioned in 1993, the facility was modified and expanded in recent years from 30 MW to its current capacity of 38 MW. HELCO is contracted to purchase power from this facility at different tiered on and off peak hours ranging from $0.1257/kilowatt-hour to $0.0640/kilowatt-hour through December 2027. The facility produces approximately 21%-22% of Hawaii island's annual electricity needs. PGV shut down operations in May 2018 due to the Kilauea volcanic eruption and lava flows impacting the PGV facility and surrounding area. Future operations for PGV are unknown at this time.
