Nevada approves SolarCity, Berkshire unit's rooftop solar pact

(Reuters) - Nevada's utility regulator on Friday approved a settlement between SolarCity Corp and the NV Energy unit of Warren Buffett's Berkshire Hathaway Inc that grandfathers roughly 32,000 rooftop solar energy customers into older, more favorable rates for 20 years. The 3-0 vote by the Nevada Public Utilities Commission came nine months after that body, with NV Energy's support, approved new charges and reduced subsidies for people who had installed or applied to install rooftop solar.
