Regulators look into grandfathering solar users

NV Energy and solar companies are due to send regulators arguments on whether to "grandfather" existing rooftop solar customers into older, lower rates.
   
Existing solar customers have pleaded with regulators to allow them to keep the more favorable rates. Regulators on the Nevada Public Utilities Commission said they didn't have enough information on whether grandfathering is a good idea, and asked interested parties to answer a list of questions by noon on Monday.
   
A solar company coalition called The Alliance for Solar Choice is asking for a deadline extension, although PUC staff recommended against that.
   
NV Energy said they will propose grandfathering existing rooftop solar customers into old rates for up to 20 years, although companies like SolarCity say the proposal doesn't go far enough and should include future customers.
