Annual review shows no change to price basis for prudential support calculation
April 28, 2016
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 at:
- $94/MWh for metered market participants that are distributors
- $102.10/MWh for other types of 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 15 per cent or more year-over-year, the price basis used by the IESO is modified.
Tools are available through the IESO Portal to track exposure, review posted collateral, and propose adjustments to prudential support. More information on these tools can be found through the Guide to Prudentials at the IESO and Online IESO's guide to Submitting Prudential Support.
