My hydro bill didn't agree with my calculations this month because of the annual January adjustment to regulatory charges. Didn't know this happened every January. This is the document that went under the radar, at least for me.

Wholesale Market Service (WMS) rate went up by $0.0011 per kWh and Remote Electricity Rate Protection (RRRP) charge went up by $0.0002 per kWh for a total increase of $0.0013 per kWh. It's small but I wanted to make sure my utility was trying to skim a few dimes from everyone because of some billing glitch.
Reading that October rate announcement, I didn't realize the OEB tries to put positive spin on things. They point out the rate decrease but in smaller text describe the reduction in the Ontario Electricity Rebate as a change. You may think it's ok for the rebate to decrease when rates decrease, but the distribution charges aren't decreasing so that portion costs more when the rebate decreases.
