ATLANTA — Georgia Power has filed a tariff with the Public Service Commission to recoup finance costs for two new nuclear reactors through rate increases.

The Nuclear Construction Cost Recovery tariff was authorized by the Georgia Legislature in 2009. The tariff was filed today and would go into effect in January if the PSC votes to approve it.

Georgia Power says residential customers using about 1,000 kilowatt hours per month will see an average annual increase of about 1.4 percent, or $1.74 a month, over the first five years of the tariff.

The increase next year will be higher, about $3.73 per month, because it recovers costs on capital investments incurred since construction began in 2009.

The utility says recovering finance costs during construction reduces the overall cost of the plant by $300 million.
