Hawaii Electric Light (HEL) on Monday, April 18, said it was experiencing narrow generation reserves this week after two unexpected trips of the Hamakua Energy Partners (HEP) power plant on April 13 and 14.
The utility is a Hawaii Electric (NYSE:HE) company.
The HEP plant remains out of service and is not expected to return until Friday April 22.
To meet customers’ electricity needs, HEL is running all its available firm generating units. It is working to return its Hill 6 steam plant early from its annual overhaul and planned to have it return to service soon.
Hawaii Electric Light’s Puna steam unit, which was on standby status, was returned to active service as well.
Renewable resources like wind and hydro are adding generation during the peak use hours and helping to increase generation reserves during this time, the power company said in a news release.
“While we currently expect to have enough generation this week, we want to share this information with our customers to help them plan ahead just in case,” said Rhea Lee-Moku, Hawaii Electric Light spokeswoman.
“In the event we have a sudden loss of generation, we may need to ask customers to conserve electricity use during the evening peak hours between 6 to 8 p.m.,” the spokeswoman added.
