Change to Price Basis for Prudential Support Calculation
December 23, 2021
The IESO’s annual review of the price basis used to determine market participants’ prudential support obligations has found that the prices for metered market participants that are not distributors require updating. The price basis for distributors remain unchanged.
The updated price basis are as follows:
- $101/MWh for metered market participants that are distributors
- $103.54/MWh for other metered market participants; a decrease from the previous price of $126.37/MWhFor 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.
