Transmission Rights Market

On a monthly basis, the IESO sells transmission rights (TRs) through an auction process. TRs entitle the owner to a payment if the price of energy in Ontario is different from the price in an intertie zone. The transmission rights market allows market participants to reduce price risks associated with transmission congestion and price volatility. This, in turn, can improve market liquidity.

TRs are sold for specific intertie paths through an auction process accessible through the IESO's web portal. Both short-term (one month) and long-term (one year) TR ownership are available. A price differential is paid to TR owners when the intertie zone price is different from the Ontario market clearing price.

See Market Calendars for key activities and dates associated with the TR Market.
