Shares of Genesis Energy (NZE:GNE, ASX:GNE) fell almost 1% in early trading on Monday after the firm said on Sunday that it plans to start a cold survey of Huntly Rankine power station unit 2 in New Zealand from Dec. 1, and the unit will be unavailable from that time.
The survey is subject to the proposed 10-year Huntly firming options being approved by New Zealand's Commerce Commission.
A cold survey includes all inspection and remedial work to certify a Rankine unit to continue reliable operation. The unit is stripped down and then reassembled. This usually takes several months to complete.
The unit is scheduled to be removed from service in January 2026, the company said. The proposed potential arrangements between Genesis, Mercury (NZE:MCY, ASX:MCY), Meridian Energy (NZE:MEL, ASX:MEZ), and Contact Energy (NZE:CEN, ASX:CEN) could provide for the unit to remain in service until 2035.
