Yeah, I got the sign up credit. Our power bill ranges from about $200 in summer to about $450 in winter, but we keep the house about 24 degrees. Moving to Mercury without an hour of power I'll need to do less pre-heating, plus I installed a new heat pump in my office, so I expect the bill could go down more than expected.
Our bills are $100 Summer and $250 Winter. Two heat pumps, gas hob, and solar HW. Im home alone till April so last bill was $72, the next one will be $65 lol. So no rush to change but I will evaluate Summer, Winter and mid season bills soon. Be nice to not be tied to the 10pm free hour
