If at first you don’t succeed, wait for the next rate case. This seems to be the strategy of many U.S. utilities, which despite trying to find many novel ways to gain more revenue from customers who adopt solar under net metering policies, remain largely focused on one tried and true method: asking for higher fixed charges and minimum bills.
Throughout the first three quarters of 2017 the pace of developments on such rate change proposals have increased, with North Carolina Clean Energy Technology Center (NCCETC) finding 44 actions taken involving proposed increases of residential fixed charges or minimum bills by at least 10% in 26 states plus Washington D.C. in the third quarter alone.
This was only exceeded in the fourth quarter of 2016, when 49 actions were taken in 28 states plus Washington D.C., and such proposals have consistently been the most popular policy actions affecting solar tracked by NCCETC in its quarterly 50 States of Solar report.
As reported in the Q3 2017 50 States report, the success rate remains the same. Most of the time regulators grant part but not all of the increases that utilities are requesting, resulting in a slow growth in the national level of fixed charges and minimum bills. NCCETC notes that only one utility in the nation was granted its full requested increase, a modest increase in a fixed charge from $7 to $9 for customers of Superior Power and Light in Wisconsin.
Higher fixed charges and minimum bills are generally opposed not only by the solar industry, as they weaken the value proposition of distributed solar, but also by ratepayer advocates, as they lessen the economic benefits of energy efficiency and can increase bills for low-income customers.
Community solar marches on
But as the utility battle with distributed solar companies, and increasingly their own customers, continues, policies around community solar are also on the rise. “It’s been slow and steady, with around one state per quarter adopting a new community solar program,” NCCETC Manager of Policy Research Autumn Proudlove told pv magazine.
This quarter Illinois took the leading action, with the Illinois Power Agency publishing details of a community solar program in its long-term renewable procurement plan. Also, earlier this month Commonwealth Edison’s community solar tariff was approved by state regulators. However, as Illinois-based pv magazine contributor Mark Burger has noted, there are still a lot of details that have not yet been worked out regarding community solar in the state.
Part of the complexity is that as community solar spreads across the nation, each state is taking a different approach to how to credit customers. NCCETC notes that some of the unique approaches to credit structures it is seeing are crediting at avoided cost and adopting adders for low-income participants.
