Conditions may arise that necessitate the IESO to implement a number of emergency control actions to maintain the reliable operation of the IESO-controlled grid. These emergency control actions include voltage reductions, emergency energy purchases, and non-dispatchable load cuts. Counter-intuitive pricing occurs when the emergency control action affects demand in the market pricing sequences, resulting in pricing outcomes and signals that do not reflect actual market conditions.
As a result of discussions with market participants and other stakeholders, market rule and software changes to IESO systems were recently made with a view to ensuring a more efficient and reliable electricity system under such conditions.
