After months of hearings, regulators would not support FPL's plan to bill electricity customers for the costs of the nuclear power project, which lacks a feasibility analysis and has also had its construction postponed.
FPL first proposed expanding the Miami-Dade County project in 2006. The expansion would add a sixth and seventh reactor to the plant, which is the sixth largest nuclear power plant in the US, producing about 2,750 MW.
FPL submitted a combined operating license application for the two new units in 2009. The project has an estimated cost of about $17.8 billion and would use a pair of 1,117 MW Westinghouse AP1000 reactors. Since choosing Westinghouse to provide the reactors, the manufacturer has declared bankruptcy.
The two reactors were originally supposed to be online by 2018 and 2020, however the utility has since written to regulators the dates may be pushed back more than a decade.
In 2013, the Florida legislature began requiring nuclear projects to submit feasibility studies to state regulators before a project wins approval to start construction.
According to reports, FPL submitted these reports as required up until last year, when the utility asked regulators to waive the requirement, adding that the requirement is an undue and unfair hardship. In 2017, FPL said another report was not necessary.
