The battle over how NV Energy should handle solar panel subsidies is not over. The Nevada Bureau of Consumer Protection is asking regulators to put a hold on a controversial new rate structure for customers with rooftop solar panels. Nevada Consumer Advocate Eric Witkoski filed the request on Thursday, two days after the Public Utilities Commission voted to move forward with new rates that phase out subsidies and raise prices over five years. Witkoski says solar customers who bought their panels years ago may not have been aware that their rates could change along with those for future customers. He also says the changes could drastically alter private contracts consumers signed with rooftop solar companies, and that could be legally questionable.
