The Pakini Nui (Tawhiri) Wind Farm began generating electricity in March 2007. Developed by Tawhiri Power, LLC, the wind farm consists of fourteen 1.5 megawatt (MW) wind turbines that produce close to 21 MW of electricity, which is estimated to be enough to power 10,000 homes. The Pakini Nui Wind Farm estimates it has reduced the number of oil barrels burned each year for energy by 160,000. Power from this wind farm is purcahsed by Hawaii Electric Light Company (HELCO) at $0.1180/kilowatt-hour (on peak) or $0.1120/kilowatt-hour (off peak) (average fiscal year 2018 price) through April 2027 under a minimum 20-year power purchase agreement approved by the Hawaii Public Utilities Commission in March 2005. In 2018, Hawaii island's two existing wind farms generated approximately 14% of the island's energy needs and comprised 32% of Hawaii island's renewable energy portfolio (total renewable energy generation) for that year. In 2016, wind farm operator Tawhiri Power began seeking approval of the Habitat Conservation Plan for this facility. In April 2019, the US Fish and Wildlife Service initiatied a Programmatic Environmental Impact Statement (PEIS) review in response to applications from four Hawaii wind farms -- Auwahi Wind Farm (Maui), Kaheawa Wind Power II (Maui), Pakini Nui Wind Farm (Hawaii), and Kawailoa Wind Power (Oahu) -- to amend their Incidental Take Permits authorizing the take of three endangered species found only in Hawaii: the opeapea (Hawaiian hoary bat), nene (Hawaiian goose), and uau (Hawaiian petrel). The PEIS provides a comprehensive analysis of cumulative impacts across all four projects.
