Updating Maximum Interruptible Capacity Values and Performance Estimates for Demand Resources

In May 2014, the ISO identified that Maximum Interruptible Capacity (MIC) values for demand assets and performance forecasts for passive assets were outdated, affecting monthly reporting and compliance with tariff requirements. A software fix was deployed to enable Lead Participants to update contact information at the asset level and complete necessary updates. Participants are requested to update MIC values and provide 12-month performance forecasts before June 1, 2014. This presentation outlines the update process and emphasizes the urgency for timely participation.

  1. Demand resources working group may 2014 Kristen Emmett DEMAND RESOURCE ADMINISTRATION Updating Maximum Interruptible Capacity Values and Forecasted Performance Estimates

  2. Background • ISO determined that Max Interruptible Capacity (MIC) Values for all demand assets and performance forecasts for passive assets in CAMS had not been kept up-to-date. • The MIC’s being out of date impacts the monthly DRWG reporting, and the performance forecasts are required by the tariff. • In March ISO reached out to Participants requesting these updates. • Due to a software issue in CAMS, Lead Participants could not make these requested updates through the CAMS user interface for some of their assets. • The issue applied to measures where contact information was not populated, originating from the manual cutover in 2010.

  3. Background (Cont.) • Last week, a fix was deployed in CAMS that allows Lead Participants to add contact information at the asset level in order to complete the updates • MIC values • 12 month forecasts of performance for passive assets • Other registration parameters • Previous work-arounds, such as providing this data via CAMS Service Notes, will no longer be needed • DRA is requesting that MIC and 12 month performance forecasts be completed before June 1, 2014 • The following slides will walk through the updating process

  4. Updating a Contact (must be done first)

  5. Updating Maximum Interruptible Capacity • The terms “Max Interruptible Capacity” and “Maximum Demand Reduction Value” are used interchangeably in CAMS.

  6. Updating Maximum Interruptible Capacity (Cont.)

  7. Adding Additional Performance Estimates • Performance Estimates can be added as far out into the future as desired, click green plus sign for each additional month • Months are added sequentially, so data will have to be filled in for all prior years; enter a rough estimate if data is unknown for a past period • The tariff requires that Lead Participants provide one year of prospective estimates • For example, estimates for June 1, 2014 to June 1, 2015 should be provided by June 1, 2014.

  8. Adding Additional Performance Estimates

  9. Summary • Lead Participants that have assets requiring updates of the MIC value will be provided an email with the list of affected assets. • Lead Participants that have assets requiring prospective performance estimates should review the assets in their portfolio in a timely manner and make the necessary updates. • ISO is requesting that Lead Participants give priority to these changes and that they be completed prior to June 1, 2014.
