Here’s a summary of an analysis I did to understand the impact on me (as a grid-connected solar member) of a recent change in rates at the electric coop (Riverland Energy Cooperative) that I belong to.
My conclusion in a nutshell: I accept the new rates as they stand. They seem fairer to coop members as a whole and I’m happy to carry the impact that my solar panels have on our shared infrastructure.
I looked at three rate-change puzzlers: Demand Charge, Annual to Monthly True-Up and Rate of Return. The rest of this post goes through them at a high level, and there’s an 18-minute video at the end that goes into more detail.
UPDATE: There is a new version of the spreadsheet and an additional video on how to use it at the very end of this post.
