TALLAHASSEE, Fla. (AP) — Florida regulators are signing off on a settlement agreement that will allow customers to finally stop paying for a never-built nuclear power plant.

The Florida Public Service Commission on Wednesday approved a wide-ranging settlement with Duke Energy Florida that brings to an end a long-running saga over a proposal to build a nuclear plant in Levy County on the state's Gulf Coast.

Duke Energy abandoned plans to build the plant back in 2013, but customers kept paying costs associated with the plant. Starting in January, the average customer bill will go down $2.50 a month due to the agreement.

The proposal also calls for the construction of additional solar power plants in the next four years.

Duke Energy has more than 1.8 million customers in Florida.
