Ontario''s Independent Electricity System Operator (IESO)
posted the estimate for the May 2013 Global Adjustment (GA), and it is $66.36/MWh. Coupled with my estimate of the Hourly Ontario Energy Price (HOEP) of $25.22, the monthly wholesale commodity rate in Ontario in May is estimated to be $91.58.
In
December 2012, the HOEP was similar, at $25.51, but the GA was $40.64 - for a total of $66.15.
If you are a "class B" customer exposed to the market rate, the increase in your rate is therefore 38% in the past 5 months. Regulated price plans (including residential ones) will reflect the same costs, but not in the same months.
The last time prices approached this height, a government''s panicked rate freeze failed to prevent it''s electoral defeat. May''s commodity charge is the highest since Ontario''s market opened, and in reality it is much higher. While the HOEP exceeded $80/MWh early in 2003, it wasn''t meaningful for customers as there was a price freeze at $43/MWh introduced (with retroactive payments) after prices peaked in September 2002 at $83.14.
The IESO will eventually report May''s Ontario demand average just over 14,000MW per hour in May 2013, which is lower than they''ve reported for any month except May 2009. Don''t panic that the low total indicates we''ve returned to the depths of the recession; the IESO''s reporting is increasingly less indicative of actual supply, and actual demand, in the province.
