Latest Global Adjustment Numbers for Ontario Electricity Rates

Surly Hamiltonian focuses a lot on Ontario's hydro prices especially the Global Adjustment (the extra fee that gets charged to Ontarians to pay for the high rates of green energy and the extra power sold to Americans at a loss). The latest final numbers are out at this site for May and it is 6.76 cents per kWh. That's higher than the 5.65 number last year. This is likely due to a rainy and relatively cold May. Sunny summer months often mean high consumption which lowers the Global Adjustment. The green energy producers have to be paid regardless of consumption, so a lot of consumption spreads the hit.

The crappy weather has continued and that means the Global Adjustment is also high historically for June and July. The number for June 2012 was 5.26 and for July 2012 was 3.36. This year however the estimates are 7.91 for June (second estimate) and 7.38 for July (first estimate). That's a huge change year over year and interestingly if the July holds, the highest for all 2012 and 2013. So basically, crappy summer weather means higher hydro rates. However the weather is also colder so that probably lowers how much hydro one is consuming for AC.

This site has a lot of the data for 2012 and 2013 in tabular form.
