The Public Service Commission recently suggested the public should pay for the costs of nuclear upgrades from Progress Energy Florida and Florida Power & Light.
Costs related to construction, expansion or upgrades of power plants are expected to reach $292 million.
Approximately $150 million comes from Florida Power & Light Co. and $142 million from Progress Energy Florida.
An environmental group, Southern Alliance for Clean Energy, says the move puts the company's profits ahead of consumers.
The Public Service Commission will make a decision on Nov. 26.
FPL says its projects will ultimately reduce consumers' fuel costs.
Progress Energy is still waiting for a license to build a new plant in Levy County.
