• Two sub‐groups within the Energy Neutral Dispatch category– Energy Neutral TrinaryEnergy Neutral Trinary
• Trinary means that the dispatch and expected response is either full power charge, full power discharge, or midpoint.
• All ENT dispatched resources will simultaneously be sent to their Regulation High Limits, Regulation Low Limits, or Regulation midpoints

Regulation Market Resource SelectionRegulation Market Resource Selection
For the purposes of least‐cost Resource selection, the following penalty factors are used for any violation of the Regulation requirements constraint:
• $100/MW plus the Energy Component of the Real‐Time Locational Marginal Price at the reference point for each megawatt of Regulation Capacity shortfall
• $10/MW for each megawatt of Regulation Service shortfall
These penalty factors are used to allow the selection process to undershoot the requirements by a small amount, if meeting the requirements would be excessively costly.

Regulation Monitoring ‐ GoalsRegulation Monitoring Goals
Goals of the Regulation Performance Monitoring System g g y(RegMon):
• Encourage offers with performance parameters that (over time) match observed performance characteristics
• Encourage offers with performance parameters that provide ffi i t t i bilit t hi i t tl hi hsufficient sustainability to achieve consistently high
performance scores
• Avoid penalizing apparent performance deviations that resultAvoid penalizing apparent performance deviations that result from normal resource characteristics that are understood, but not modeled in the Regulation (AGC) dispatch, such as:
R d l ti– Response delay time– Ramp rates that vary over the resource’s regulating range.

Regulation Monitoring – Market Rule GuidanceRegulation Monitoring Market Rule Guidance
• “The performance of a Resource providing Regulation will be monitored in Real‐Time. ” (Section III.14.7)
• Achieved by comparing actual Regulation MW to the AGC signal in a systematic manner
• If a resource movement is inconsistent with the AGC Setpoint, it will not get credit for the rest of the hour (Section III.14.7)
• Specific guidance on measurement process includes:
– Tolerance band(s) based on offered Automatic Response Rate and Regulation Capacity
– Grace periods to allow reasonable time lags
– ARR : allow uncertainty up to +/‐ 20% of offered ARR
Regulation Capacity: allow uncertainty up to +/ 15% of the calculated Regulation Capacity– Regulation Capacity: allow uncertainty up to +/‐ 15% of the calculated Regulation Capacity.
• Two different Parameter sets are used in order to more accurately track the performance of resources following the two types of dispatch methodologies
• One for Conventionally dispatched resources• One for Energy Neutral Dispatched resources
T t t i d d t f d t l diff i th t f th C ti l d E• Two parameter sets are required due to fundamental differences in the nature of the Conventional and Energy Neutral AGC setpoints
• Otherwise the performance monitoring of the resources following these two different dispatch methodologies is exactly the same.

Regulation Monitoring – ImplementationRegulation Monitoring Implementation
• RegMon conducts on‐line performance monitoring of regulating resources
– It runs continuously and calculates scores every hour using that hour’s measurements plus a few minutes of measurements before (for initialization)
I h f f h ’ l ki f h AGC i f– It scores the performance of each resource’s actual tracking of the AGC setpoint for every instant that the resource was assigned to perform regulation (i.e. Unit Control Mode 6)
It scores all resources providing regulation during the hour– It scores all resources providing regulation during the hour
• Using a single algorithm/software solution that implements the Market Rule requirements, the ISO can support an accurate, transparent RIPS
• The RIPS adjusts compensation for the regulation settlement period (an hour) in proportion to the score

Regulation Monitoring – Two exceptionsRegulation Monitoring Two exceptions
• Acceptable Overshootp– AGC Setpoint is at or above (less than) the high regulating limit (low
regulating limit) and the resource’s output is at or above (less than) high regulating limit (low regulating limit)
– Acceptable Overshoot gets a 100%– Acceptable Overshoot will not override failure
• UCM6 grace periodUCM6 grace period– First few minutes a resource is in UCM6 will not count towards failure,
provided that it has been OFF UCM6 for extended duration e.g. at least an hour.least an hour.

Regulation Monitoring – Finalizing ScoresRegulation Monitoring Finalizing Scores
• Except during acceptable overshoot, output outside the wide p g p , pscoring envelope will get a 0 score for that AGC cycle.
• Regulation Interval Performance Score (RIPS) = arithmetic average of the instantaneous scores of all time intervals on UCM 6 within the regulation settlement interval
RIPS ill li l l b th• RIPS will linearly scale both:– total requested movement (mileage): service payment calculated in
Settlementsalso the integrated regulation capacity: capacity payment calculated in– also the integrated regulation capacity: capacity payment calculated in Settlements

Regulation Monitoring – developing parametersRegulation Monitoring developing parameters
• ISO is finalizing the parameters that control the performance and failure envelopes and timestimes
• Appropriate parameters for the Regulation Performance Monitor will be– Developed using historical data– Guided by the overarching goal of
• creating a performance monitoring system that reflects real world resource responsehil ill h i h ki d f l i f h d f li bili• while still having the kind of regulation performance that we need for system reliability.
• The parameters will not be resource specific – they will apply to the entire fleet of regulation resources that choose to participate in the regulation market.
• Two different Parameter sets are used in order to more accurately track theTwo different Parameter sets are used in order to more accurately track the performance of resources following the two types of dispatch methodologies
– One for Conventionally dispatched resources– One for Energy Neutral Dispatched resources
• Two parameter sets are required due to fundamental differences in the nature of the p qConventional and Energy Neutral AGC setpoints
• Otherwise the performance monitoring of the resources following these two different dispatch methodologies are exactly the same.
