Ontario's forward electricity trading has transitioned from the 2006 auction events facilitated by the OPA to screen trading with interactive bids and offers from market participants.

In December 2006, forward screen trading of Ontario electricity contracts began on the Natural Gas Exchange trading screen. This activity was moved to the IntercontinentalExchange trading platform in February 2008.

Natural Gas Exchange Inc. (NGX), a wholly owned subsidiary of TSX Group Inc., provides electronic trading, central counterparty clearing, and data services to the North American natural gas and electricity industries. Since its first operation in 1994, NGX has developed the AECO/NGX Intra-Alberta Market into one of the most liquid spot and forward energy markets in North America.

The IntercontinentalExchange (ICE) operates global commodity and financial products marketplaces of diverse futures and over-the-counter (OTC) markets offering access to contracts of products ranging from crude oil, power, to agricultural commodities.

All successful transactions of Ontario forward energy products on the ICE screen are centrally cleared by the NGX, effectively making NGX the buyer to every seller and the seller to every buyer. In this role, NGX is obligated to ensure the performance of the transaction.

The Ontario energy products listed on NGX/ICE and available for trade include Flat, On-Peak and Off-Peak contracts. It is possible to trade everything from Same Day and Day Ahead through to Calendar Year and Term products.

The OPA continues to work with NGX/ICE and market participants to facilitate the development of the Ontario forward price curve for electricity.
