Jan 30 (Reuters) -

Hawaiian Electric lifted a request for customers to conserve electricity, ending a period of rolling blackouts imposed on Hawaii island earlier on Tuesday, after repairs to generators.

The utility had imposed 30-minute rolling outages on the state's island of Hawaii after unexpectedly losing supply from three generators and were unable to call on wind power as a backup.

"About 25,500 customers around the island were without power for about 30 to 60 minutes between 8:38 a.m. HST and 10:52 a.m HST," Hawaiian Electric said in a statement on its website announcing the end of the conservation request.

The Honolulu-based electric utility earlier said its largest generator, Hamakua Energy, was under repair and unable to reach full output. Three combustion turbine units had also tripped offline, and another was under repair.

Hawaiian Electric did not immediately respond to a Reuters request for additional comment.

The energy shortfall was unrelated to a fire at Hawaiian Electric's Panaewa Substation on Monday evening, the company said.

Hawaiian Electric is facing multiple lawsuits claiming the utility was to blame for a wildfire that tore through the island of Maui last year, killing at least 100 people.

In November, the company said it was unable to submit its quarterly filing with U.S. securities regulators on time, due to financial contributions it made towards victims of the wildfire.

Shares of parent company, Hawaiian Electric Industries , closed down 1.6%. (Reporting by Seher Dareen in Bengaluru and Laila Kearney in New York, additonal reporting by Brijesh Patel; Editing by Arun Koyyur and Aurora Ellis)
