Ontario’s electricity export tariff

Special to The PostMedia Network, June 14, 2018


Former Energy Minister Chiarelli and his claim of a $6B profit on surplus electricity exports. “You can verify it.” No, you can’t.

Many will recall Bob Chiarelli, when in the position as Ontario’s Minister of Energy, was questioned on the costs of exporting our surplus electricity on TVO and stated: “since 2008, the province of Ontario – and you can verify it with the IESO – has made a $6 billion profit on the trading of electricity.”

Needless to say Minister Chiarelli was called out by the media and opposition parties for making such a spurious claim.

Let’s look at Ontario’s 2017 electricity exports and see what he would claim about them. The U.S. Energy Administration Information (EIA) in a recent release, had the following information posted from data supplied by Canada’s National Energy Board (NEB):

“Electricity accounts for a small, but locally important, share of bilateral trade. In 2017, the value of U.S. imports of electricity from Canada increased for the second straight year, reaching $2.3 billion*. The United States imported 72 million megawatt hours of electricity from Canada in 2017 and exported 9.9 million megawatt hours, based on data from Canada’s National Energy Board.”

As it turns out, Ontario’s exports of 19.1 million megawatt hours (MWh) in 2017 represents 26.5% of the 72 million MWh reported as exported by the NEB and those 19.1 million MWh generated “revenue” of $496.6 million (approximately) made up of the $15.80/MWh of the yearly average HOEP (hourly Ontario energy price) as reported by IESO and another $10.20/MWh for transmission** costs.

The implied revenue generated represented 16.6%* of total Canadian electricity revenue versus 26.5% of total Canadian electricity exports. The Ontario based generators of that 19.1 TWh of power were paid a yearly average of $115.5 million/TWh (yearly average includes HOEP plus global adjustment based on the IESO’s December 2017 monthly summary.

That means the cost to Ontario ratepayers for exported power was $1,709.5 billion and the credit (net of the monies to Hydro One of $194.8 million for transmission) resulted in Ontario’s ratepayers picking up the missing revenue of $1,507.7. Anyone with a small math knowledge would not refer to that as a profit as it would represent a cost of about $300 per Ontario household.

Export tariff?

The cost to ratepayers of electricity exports in 2017 at over $1.5 billion and prior years played a significant role in driving up electricity rates and represented almost 10% of total generation costs. To put that in current context, Ontario’s ratepayers were slapped with an “export tariff” by our Ontario government of 88% which greatly exceeds the US tariffs recently announced by the US government on Canadian manufactured steel and aluminum.

Getting slapped with only a 10% or 25% tariff would be a net benefit to Ontario’s ratepayers.

*Presumably US dollars so would represent approximately $3 billion CDN dollars at a $1.30/$1.00 exchange rate.

**A large part of these revenues ($194.8 million estimated) went to Hydro One who control about 99% of all transmission in the province.
