No estimates were immediately available on how the agreement would affect customer’s bills.
Customers already are paying surcharges of about $100 a year, on average, to finance construction of the two new reactors at Vogtle. Georgia Power, a state-regulated monopoly, owns roughly half of the project to double the size of the nuclear power plant.
Several months ago, the PSC ordered the company and the agency’s staff to negotiate an agreement on how Georgia Power and customers would split up the cost overruns at the nuclear expansion near Augusta, which is $3 billion over budget and three years behind schedule.
One reactor is currently slated to be completed by the end of 2019 and the other by the end of 2020.
Earlier this week, the PSC granted an extension to Oct. 28 of the Wednesday deadline to reach that tentative deal.
