Dive Brief:

• The Colorado Public Utilities Commission (PUC) has decided to review the costs and benefits of rooftop solar in a new investigation on the state's net metering policies.
• As part of its renewable energy program, Xcel Energy had asked the PUC to change some accounting procedures for net metering as a first step for tackling the issue.
• Solar organizations strongly supported the PUC's decision.

Dive Insight:

Arizona and Colorado are also taking a sharp look at their net metering policies. The outcomes in these three states will likely affect policies across the U.S. Expect an intense investigation into how adding rooftop solar panels affects the grid and how any related costs and benefits should be shared by a utility's customers.
