History

edit

Eastland Generation evolved from the Poverty Bay Electric Power Board. During the electricity sector reforms of the 1990s, the PEPB was rebranded as Eastland Energy, then the Eastland Network, with ownership vested in a community trust.[1] The Eastland network expanded into electricity generation in 1999 with the purchase of the Waihi hydroelectric station.[1] In 2010, the generation assets were separated into a separate company following the purchase of a geothermal power station.[1]

In 2016 damage to the Waihi dam caused ongoing pollution to the area's drinking water, resulting in the company having to pay the Wairoa District Council more than $100,000 in cleanup costs.[2]

In 2018 the company completed construction of the 24MW Te Ahi o Maui geothermal power station.[3] In June 2021 Eastland acquired the 26 MW TOPP1 geothermal station.[4] In August 2023 it received fast-track consent for its Tāheke 8C geothermal power station.[5] In November 2023 it commissioned Te Ihi o te Ra, its first solar power station.[6][7]

In May 2024 Eastland Group sold 50% of the company to the Obayashi Corporation as part of a capital raise.[8]
