Hawaii state officials have returned applications for two new geothermal wells in order for the utility to make revisions.
The Hawaii Tribune-Herald reported Monday that the state Department of Land and Natural Resources has commented on the applications submitted by Puna Geothermal Venture in April.
A PGV spokesman says the company’s response to the agency should be provided within a week.
The land and natural resources department must approve the one-year permit applications for new wells.
The state Public Utilities Commission will require PGV and Hawaii Electric Light Company to hold a public hearing regarding construction of new transmission lines to the plant.
The state’s only geothermal plant produced 31% of the island’s power and about half of its renewable energy in 2017, according to PGV and Hawaii Electric Light officials.
PGV may build as many as 28 wells under an operation plan approved in 2006.
The company now has 11 wells — five for injection and six for production — ranging in depths between 4,000 and 8,000 feet (1,219 and 2,438 meters), officials said.
The applications are part of the company’s attempt to resume operations after last year’s Kilauea volcanic eruption, which shut down the 38-megawatt geothermal power plant in Puna on the Big Island.
PGV and Hawaii Electric Light Company officials say the state’s only geothermal plant produced 31% of the island’s power and about half of its renewable energy in 2017.
