Quick look at the new ratesMy conclusion is that it seems to raise costs for the average use case, but it's possible to lower costs slightly compared to their current level by shifting usage to off-peak periods (though I think it's unrealistic to expect to be able to save money). The price for on-peak usage (6 hours per day on weekdays) rises a lot.
The old "anytime" rate, on my latest bill (April-June), was 6.8 cents/KWh.
The new rates are:
Off-peak: 5.9 c/KWh
Mid-peak: 8.9 c/KWh
On-peak: 10.7 c/KWh
Assuming a constant load (unrealistic), and weighting these rates by the number of hours a week they apply, you get a new composite weighted rate of 7.29 c/KWh, about 7% higher than the current "anytime" rates.
If you want to keep paying the same amount as today, you'd have to have a usage profile solving for (X: off-peak, Y: mid-peak, Z: on-peak):
5.9X + 8.9Y + 10.7Z = 6.8
(any point on that plane will yield the same cost as today's rate, but the practical application is unintuitive)
ReportingThe reporting is actually pretty cool:
It presents hourly, daily, and monthly stats, and allows downloading the data as a spreadsheet. This is actually an improvement I've been wishing for for a long time, in contrast to the previous data, which only gave you monthly usage. Now I wish I could get the same data for my gas consumption.
