Well, from January to November the hydro rates have gone up about 6% here.  There was no price increase in the cost per KWH, however the electricity rebate was reduced from 19.3% to 13.1%.  No big deal.
However the new rates that just started in November are considerably more expensive.  The rate plan I am currently on has increases ranging from 28.7% to 39.3% (different increases for different usage times).  I suspect that they will initially employ a much higher rebate to reduce the number of complaints and then just reduce the rebate over time.

Of course this just gives me more reason to stop being so lazy and finish building up the second transformer so I can move more stuff over to the inverter.  The items I would like to move over are A/C, stove and dryer.  I have all the materials for the inverter, but will need some items to beef up the battery charger.

Note:  After a little googling, I see that the rebate has gone from 13.1% to 23.5%, which makes the effective increase from 16% to 22%.  

I guess the party is over.

Love the photo, we will be facing a similar problem here before long.

I can report that I'm still 100% off grid with total disregard to the power we are using, dual ovens, Hotplates, washer dryer, big hot water system, 3 aircons, workshop, and on it goes, through winter and a few days with low solar and two days with almost none, lowest battery level was 38% after two days of no solar.

I'm still amazed, the Inverter has seen 14kW at times, and often runs with constant cycling between 8kW to 10kW for an hour or so each day. It runs virtually cold, highest  FET heatsink temps were 38° and the Toriods have never gone above 42°, which basically feels like a slight warmth to the touch on a 37°c day
