The Florida Public Service Commission is holding a hearing on whether the state's two largest electric utilities can charge customers for costs related to incomplete nuclear power plant projects in 2013.
The panel is hearing testimony Wednesday and will rule at a later date.
Florida Power & Light Co. is seeking $151.5 million for upgrading existing facilities at its St. Lucie plant and adding two reactors to its Turkey Point plant.
If approved, that would add $1.69 to the monthly bill for 1,000 kilowatt hours, which is about average residential use.
Progress Energy Florida is seeking $13 million to repair a shut-down reactor at Crystal River.
The commission earlier this year approved limited recovery costs for a proposed Levy County plant as part of a larger rate settlement.
