Utility rate cases have become a major battleground over the future of distributed solar generation and the evolving structure of the nation’s electricity system.
In the Midwest, Wisconsin has been ground zero, with state regulators last year approving three rate cases that made solar much less viable through several mechanisms, including a drastic increase in the fixed monthly charges for all ratepayers, regardless of how much electricity they use.
The next major development on that front will be a case that Xcel Energy is expected to file in late spring or summer. The Wisconsin Public Service Commission has made it clear that it welcomes requests for increased fixed charges and related measures, as RENEW Wisconsin program and policy director Michael Vickerman and other energy experts see it.
But a March 26 decision by the Minnesota Public Utilities Commission (PUC) on an Xcel rate case in that state could mean Xcel is unlikely to request the type of fixed rate increase that other utilities in Wisconsin have been granted.
