Hawaiian Electric Co. is asking its Oahu customers to cut back on their air conditioners, limit hot showers, dishwashing and and cooking to avoid power outages this evening.

The hot, muggy weather, light winds and a downed power plant have contributed to heightened demand and decreased power supply, according to a HECO press release. A power plant owned by Kalaeloa Partners is out of service due to “unexpected repairs” and Oahu’s wind farms aren’t generating a lot of energy because of the low winds.

Customers are being asked to conserve energy between the hours of 5 p.m. and 9 p.m.

“Although Hawaiian Electric anticipates it will be able to serve the evening peak demand for electricity, available backup generation reserves will be very low,” according to the press release. “Should demand for electricity remain high and another unplanned loss of generation occur, power outages may occur.”
