No Change to Price Basis for Prudential Support Calculation
November 24, 2022
The IESO’s annual review of the price basis used to determine market participants’ prudential support obligations has found that no changes are required. The price basis remains unchanged as follows:
- $101/MWh for metered market participants that are distributors
- $103.54/MWh for other metered market participants
For prudential calculation purposes, the IESO is required to determine a market participant's prudential support obligation using prices published in the Ontario Energy Board's electricity price forecast. If these prices have increased or decreased by at least 15 per cent, the price basis used by the IESO is modified.
