Net metering is one of the most emotionally charged issues in renewable energy, and now it's back in the spotlight. A panel discussion at PV America East in Philadelphia last week explored ways that utilities and ratepayers can agree on how to quantify net metering's benefit. Almost simultaneously, a major utility exec's public criticism of net metering is fanning the flames once again.
Net metering policies are in place in 43 states and Washington DC -- a "wildly successful" expansion, noted PVA panelist Evan Dube from SunRun. Two studies released in recent weeks, looking at California and Vermont, calculate that net metering's annuals benefits to ratepayers outweigh costs. The Vermont study in particular takes a broader view of net metering "writ large" and should be a model to use going forward, he noted.
