Business executive Lindy Miller said Thursday she will report raising more than $1 million in her bid to unseat a Republican incumbent to become the sole Democrat on the state's Public Service Commission.

Miller’s fundraising disclosure, which reports how much cash she’s raised through Sept. 30, will feature more than 2,300 donors and show she has more than $400,000 in cash on hand for the down-ticket race against incumbent Chuck Eaton.

The first-time candidate said her fundraising figures in a low-profile contest shows how the five-member commission “can be a force to unleash opportunity in the state and not just a rubber stamp for special interests.”

That far outpaces the fundraising rate for past PSC candidates. In this year’s race, Eaton has yet to disclose his latest financials, though he reported raising roughly $170,000 through June.

Democrats hope to gain a foothold in the PSC, which regulates Georgia's utilities, by vowing to be better watchdogs over Georgia Power's embattled Plant Vogtle nuclear reactor project. Eaton and other commissioners say they've taken a series of steps to safeguard Georgians.

One other PSC seat is up for grabs. Republican Tricia Pridemore, who was appointed to an open seat earlier this year, faces Democrat Dawn Randolph in November.
