State regulators are poised to decide whether to approve a controversial $1.8 billion proposal that would lead to Florida Power & Light adding 20 solar-power plants over two years.

The Florida Public Service Commission will take up the issue next week after its staff issued a 46-page recommendation calling for rejection of FPL's plan for the "SolarTogether" program. The proposal has drawn opposition from the state Office of Public Counsel, which represents consumers in utility issues, while receiving support from a variety of backers such as Walmart, the Miami-Dade County Commission, the Broward County Commission and the Southern Alliance for Clean Energy.

The controversy centers primarily on the way the program is structured and its different effects on FPL customers.
