GENERAL: MRP: Joint venture power station temporarily withdrawn
Please note the following news release from the Nga Awa Purua Joint Venture
relating to maintenance at the Nga Awa Purua Geothermal Power Station:
Nga Awa Purua Joint Venture has temporarily withdrawn its geothermal power
station from the market to carry out repairs on the steam turbine, and is
scheduled to have the station near Taupo operating again within 1-2 weeks.
Joint Venture Chair, William Meek, said that during a planned outage for
routine maintenance, inspections found that the turbine blades were being
affected by geothermal fluids used to power the plant. The turbine was
modified to allow ongoing operation, reducing operating capacity to about
95%.
"This shut means we can open up the turbine so that we can properly assess
the issue to increase reliability of the plant through until permanent
repairs can be made in about 15-18 months."
He said the maintenance outage would not have a material financial impact,
with revenue losses mitigated by current wholesale market conditions. The
current estimated repair and turbine blade replacement cost to the joint
venture is expected to be about $15 million in FY2015.
