BAINBRIDGE ISLAND — More than 5,100 Puget Sound Energy customers on Bainbridge Island have been without power since 11:53 a.m. today.

Power to a small portion of the affected area was expected to be restored by 3 p.m., according to Puget Sound Energy’s website.

A spokesperson for Puget Sound Energy said the Murden Cove substation was taken offline after oil was discovered to be leaking from one of the transformers at the station. Power has mostly been returned to the island with the exception of about 1,500 residents who remain without power.

Officials with PSE expect power to be fully restored by 3:30 p.m. today.
