The power has been out on a stretch of Silver Strand Boulevard extending from Coronado down to Imperial Beach, in addition to areas across the bay, for more than an hour, according to San Diego Gas & Electric.
The affected areas include the Cays, North Island Naval Air Station and Naval Base San Diego and areas near the Tijuana Estuary.
The outage was reported at 8:28 p.m, but power should be restored before midnight, utility officials noted on SDG&E's website.
Officials attributed the outage to a “suspected problem in the overhead electrical system” and said it had affected 1,775 customers.
