Duke Energy Customers will no longer have to pay for a nuclear plant that was never built. 

The Florida Public Service Commission approved a settlement Wednesday that will lower the average customer bill by $2.50 a month, starting in January. 

Duke Energy abandoned plans to build the plant back in 2013, but customers kept paying costs associated with the plant. Those costs will no longer be added to customers' bills starting next year. 

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.
