Independent Electricity System Operator (IESO)
The opening of Ontario’s nodal market has been marked by real-time volatility and unusually high operating reserve prices.
IESO politely said “no” to many of the stakeholder-requested changes to the design of its proposed Local Generation Program, but noted it will include the raised concerns in its report to the Ontario government in July and signaled it was open to further discussing others before then.
Ontario’s nodal market is showing promise one month after its launch, with improved price certainty, increased day-ahead trading and LMPs reflecting expected congestion patterns, IESO officials say.
Electricity cooperatives, independent power producers and biogas generators have asked IESO to reconsider key components of its proposed Local Generation Program.
IESO is changing how it projects renewable generation output and its accounting for imports and planned loads in the forecasts it uses to manage generator and transmission outages.
