Applicable to RTDR and RTEG Load Reduction Assets with FML Baselines

Asset Registration Issues Related to Outage and Baseline Tariff Changes

Issue Background• Currently, there are no provisions to register a load reduction measure at

a facility with any distributed generation (DG) without collecting meter data from the DG.– Such assets are allowed, but the baseline type is required to be ‘Total Facility Load’, or

‘TFL’ requiring the participant to provide metering from all distributed generation at the site as well as the load metering.

• Some load reduction measures were registered at facilities that apparently later installed distributed generation such as small solar PV without notifying the Lead Participant, so the assets were not converted from ‘Facility Metered Load’, or ‘FML’ to TFL.

• Part of the tariff changes expected to become effective on June 1, 2014 allow for such FML assets to exist starting in June 2014.– This will provide a means for participants to avoid providing telemetry from such DG

units, as well as a means to consolidate RTDR assets at a facility into a single asset.

Issue Background (Cont.)• The new tariff provisions allow for FML metering for assets that

include both load reduction and distributed generation, so long as there are no additional registered dispatchable DG assets located at the facility.– However, the lower cap for the adjusted baseline for such FML assets is

not zero if the facility is capable of pushback but rather the maximum possible pushback as per the facilities’ interconnection agreement.

– In addition, ISO needs to know which FML assets are capable of pushback so that positive load data reflecting pushback is not flagged as invalid

– ISO currently does not have this information for FML assets that may have DG installed

• In addition, there are special considerations for facilities that may wish to consolidate their RTDR assets

Proposed Approach for Implementation

• These tariff provisions are being implemented in a two phased approach:– A process has been established for collecting the necessary data from

Participants for existing and any new registrations that are impacted will be implemented such that pushback data will not be flagged and the adjusted baseline cap tariff language will be implemented in the baseline telemetry system (blts).

– New CAMS functionality will be released around August 1 that will include functionality for participants to provide the necessary data directly into CAMS.

• The first phase is described in this presentation, and the second phase implementation details will be communicated at the July or August DRWG.

Implementation Details

• ISO has reviewed meter data and believes that there may be about 30 assets that are currently registered with the FML metering configuration that may have DG installed at the facility.

• ISO will be contacting Participants this month to request that these facilities be contacted to determine:– Is there DG at the Facility?– Does the DG run in parallel with the grid?– What is the maximum allowable pushback for the facility based on the

interconnection agreement. (A copy of the agreement will be requested.)

5

Implementation Details (Cont.)

• Participants are requested to provide this information for these assets by May 20th via a CAMS Service Note.

• Until this information is provided, any intervals during which pushback is occurring will continue to be flagged as invalid– Performance and baseline influence is set to zero for such flagged

intervals

• Once this information is provided, ISO will accept pushback data as valid and will apply the new adjusted baseline capping to these assets.

• The ISO list may not be inclusive of all FML assets with DG – Participants should also review their other FML assets.

6

Asset Consolidation Considerations

• The implementation of the new provisions allowing Participants to consolidate multiple RTDR assets into a single asset will involve retiring all existing assets and registering a new FML asset.

• The baseline for this asset must be established from retail delivery point load data on non-interruption days.

• Until the new asset has an audit record, it will not contribute to any resource DRV based on audits.

• These considerations may dictate the desired timing of these conversions.
