Prior to executing the real-time market optimization, the market operator evaluates if the energy imbalance market entity has submitted enough base schedule energy to balance the EIM demand forecast or ISO demand forecast, which ever forecast is applicable, of a Bblancing authority area. If the EIM entity has chosen to submit base schedules to balance the EIM demand forecast or has submitted base schedules that are outside of /-1% of the ISO demand forecast, Settlements will analyze the accuracy of the base schedule. If the hourly meter load is within /- 5% of the hourly base load schedules, settlements will not assess over and under scheduling settlement. However, if the meter load quantity exceed /-5% of the hourly base load schedules, settlements will assess over and under scheduling settlement.
Under the current assessment of the over and under scheduling settlement, the settlement system is comparing the hourly base load schedule to the hourly metered demand quantity. The hourly metered demand quantity is calculated as the sum of the hourly metered load plus hourly metered dispatchable demand resource. The inclusion of the hourly metered dispatchable demand resource is resulting in inaccurate assessment of over and under scheduling settlement for those balancing authority areas which have dispatchable demand resource in their supply portfolio.
The proposed solution is to remove the inclusion of dispatchable demand resource from the over and under scheduling assessment by comparing the hourly base load schedule to the hourly metered load quantity.
