The net metering and distributed generation revolution is truly underway. As of 2011, 225,578 customers are net metering a total of 2,668 megawatts. Even more important than those impressive facts is that net metering is experiencing explosive growth. www.eia.gov/electricity/monthly/update/. From 2003 to 2010, the number of customers who were net metering increased at a rate of 56% per year, while net metering capacity jumped 71%.
Solar dominates the net metering market with 97% of the net metered capacity being solar. Indeed more than half of the 7,000 megawatts of solar that was installed across America by the end of 2012 was likely net metered.
While 2012 data is not yet available, the growth of net metering certainly continued in 2012. And so the number of net metering customers almost certainly exceeds 300,000, and net metered capacity now tops 4,000 megawatts. Net metering and distributed generation are now big enough to impact power markets!
