Hawaiian Electric customers on the Big Island are being asked by the utility company to conserve electricity from 5-9 p.m. each night this week.
The need to conserve is prompted by the unavailability of Hāmākua Energy Partners, the island’s largest independent power producer. Hāmākua Energy Partners, an independent power producer, normally supplies 60 megawatts of power to the Hawaiian Electric grid, but is currently unavailable. It is not known when the Hāmākua Energy Partners units will be returned to service.
Hawaiian Electric’s Hill Plant Unit No. 5 also is undergoing annual scheduled maintenance. It normally supplies 14 megawatts of power. In addition, wind resources are also forecast to be low.
Hawaiian Electric expects to have enough generating capacity to meet the early evening peak demand. Energy conservation by the public can help ensure sufficient power is available to meet demand, which increases in the early evening.
Suggested conservation steps include turning off or reducing use of lights and air conditioners, delaying showers, laundry and dishwashing activities and going out for dinner or minimizing cooking until later in the evening.

By reducing demand, Hawaiian Electric can ensure enough electricity is available and prevent the need to initiate rolling, 30-minute outages. If rolling outages are necessary, the utility company will make every effort to use social media to notify customers in the affected areas in advance.
