Gulf Power, which serves nearly 500,000 customers in eight Northwest Florida counties, has filed a request with the Florida Public Service Commission to add a storm restoration surcharge to electricity bills to recover 342 million dollars in costs associated with power restoration following Hurricane Michael. The company is proposing an $8.21 per month surcharge for residential customers using 1,000 kilowatt-hours of electricity per month. Gulf Power said the storm restoration surcharges would be spread over five years.
