The state Supreme Court rejected a business group’s challenge to a decision that allowed Florida Power & Light to recoup money from customers for a series of solar-energy projects.

The Supreme Court unanimously ruled in favor of the Florida Public Service Commission, which in 2017 approved FPL’s plan to recover the costs of the projects through base electric rates. The Florida Industrial Power Users Group, which includes large commercial electricity customers, challenged the approval, contending, in part, that the projects would not be cost-effective.
