Locational Pricing (SE-25)

The purpose of this initiative is to examine the implications on stakeholders and market efficiency of changing how Ontario’s real-time electricity price is calculated, by making the calculation better reflect the impacts of the transmission system.



The IESO will address pricing model options beginning with a pricing study that examines the various forms of locational pricing that are used across the industry. This study is being conducted at this time for the following reasons:
  • stakeholder interest,
  • increasing congestion management settlement credit complexities, and
  • a recommendation in the latest market surveillance panel report to introduce locational pricing
  • as work begins on a day-ahead market design, the fundamental question of how prices will be calculated needs to addressed.

The study results will be taken into consideration in design of the day-ahead market.
