How many homes could have benefitted from the excess power Ontario wastes, or sells off cheap?
Recently reading comments on an article related to the cost of wind power generation in Ontario, I was struck by a simple message.
The commenter had obviously visited the IESO “Data Directory” and reviewed one item labeled Intertie Flows; he observed that IESO had exported 3,000 MWh (megawatt hours) in an hour. He then observed that the exported power could have supplied 4,000 homes with free power for a month. (Here’s the math: 3,000 MWh equals 3 million kWh; the “average” Ontario household consumes 750 kWh per month, so divide the 3 million by 750 and the answer is 4,000.)
This simple fact has not been picked up on by the media and yet, it is an easy way to shed more light on Premier Wynne’s “mistake” and our rising electricity rates. The commenter also suggests going further and examining a full quarter to determine how many Ontario households would benefit from no exported power.
Excess wind and solar costs us
To be fair, while Ontario has frequently exported 3,000 MWh, we also import electricity generated elsewhere presumably at similar market prices. Those net exports or net imports (very infrequent for Ontario) are contained in the Intertie* hourly reports posted by IESO. Let’s look at the first three months of the current year.
To begin, IESO’s Monthly Market Reports for January, February and March of 2017 indicate Ontario’s “average net intertie schedule” for the first quarter of the current year totaled 2,909,000 MWh. While that was happening, industrial-scale wind turbines were generating over 3.9 million MWh in the same three months, and were also required (by IESO) to curtail (and be paid for) another 536,000 MWh. So, the wind power developers picked up about $620 million for those three months.
To make matters worse, the average of the Hourly Ontario Electricity Price (HOEP) received (via the traded market) over those three months was only $22.72 per MWh or 2.27 cents per kWh. That means Ontario received $66.1 million for the sale of the 2.9 million “intertie” MWh, while the average cost paid by ratepayers at 11.1 cents/kWh means the cost of those exports was almost $324 million.
Reducing power bills by 25% is peanuts—kill the contracts
Let’s go farther: if 1.3 million (28% of all residential households) of Ontario’s average ratepayers could have purchased those net exported kWh over the three months at the same price they were sold for, the 2250 kWh they consumed would have cost them $51 instead of the $250 they were billed. That would have reduced their cost of electricity by 390%. That makes Premier Wynne’s supposed 25% electricity bill reduction pale in comparison.
If the Premier really wants to lessen the burden on future ratepayer bills she should immediately cancel any wind and solar contracts that have not broken ground, and suspend any all future procurement of these unreliable and intermittent generation sources.
*Intertie is defined as an interconnection permitting passage of current between two or more utility systems.
