Pricing data for IESO (Ontario) is now live! We’ve added zonal, location-based pricing datasets for the province, bringing the total number of energy datasets available for Ontario to nearly 500.

Roughly a year ago, Ontario’s market renewal introduced location-based pricing to better manage congestion across the grid, replacing a single province-wide price with prices that vary by zone. That shift makes where a facility sits on the grid, and not just when it runs, a real driver of revenue and cost. Having this data in Erode means you can compare generation or storage output directly against the zonal price it’s actually exposed to, rather than a provincial average that only tells part of the story.

Whether you’re managing a battery, a hydro facility, or a portfolio spread across multiple zones, this data is ready for you to explore now.
