ERCOTs Response to ERS Capacity from ERS Generators Self-Deploying during Pricing Events Mark Patterson Manager, ERCOT Demand Integration
ERS Generator Response during Pricing Event and near 4CP Day ERS Generator fleet obligation 310 MWs ERS generators that deploy only for emergencies/ERCOT instruction have a total ERS Obligation 14 MWs (not included in this analysis). ERS generators that also deploy outside of emergencies have a total ERS Obligation 296 MWs November 29th was the largest price response by ESI-IDs on real-time pricing or block and index in 2016. This should provide a worst case scenario for the ERS fleet responding to prices. August 2nd was chosen because it was both a pricing event and near 4CP day September 15 QMWG Meeting 2 PUBLIC

WMS Request to ERCOT Bring back suggestions for resolving the issue of ERS Generators self-deploying during pricing events. September 15 QMWG Meeting 5 PUBLIC
Capacity from ERS Generators Capacity Reserved for ERS* Total Output Capacity from ERS Generator Injection Capacity Self Serve Capacity * Only Capacity Reserved for ERS is obligated to provide ERS and therefore ERS payments are based on this capacity s ability to meet its availability and performance criteria September 15 QMWG Meeting 6 PUBLIC
Clawback Suggestion for Capacity Reserved For ERS Capacity Reserved for ERS 3 year Transition Period 1st Year 1/3 of any revenue received from ERCOT for energy payments* will be clawed back from the ERS Payment, not to exceed total ERS payment for the ERS Contract Period. 2nd Year 2/3 of any revenue received from ERCOT for energy payments* will be clawed back from the ERS Payment, not to exceed total ERS payment for the ERS Contract Period. 3rd Year and after 100% of revenue received from ERCOT for energy payments* will be clawed back from the ERS Payment, not to exceed total ERS payment for the ERS Contract Period. * Energy payments are exclusive of energy when deployed for ERCOT instructed events (emergency and test) and properly scheduled self-tests September 15 QMWG Meeting 7 PUBLIC
Clawback Suggestion for Capacity Reserved For ERS The clawback of the ERS Payment based will be applied at the ERS Resource level and not at the QSE portfolio level. In addition the clawback will not be applied to only ERS Time periods in which the energy payments were realized. For ERS Generators co-located with an ERS Load and opting for joint evaluation the ERS payment for both the ERS Generator and ERS Load will be available for clawback. If known in time for the ERS RFP any money clawed back will be carried forward to remaining Standard Contract Terms remaining in the ERS Program Year. September 15 QMWG Meeting 8 PUBLIC
Clawback Suggestion for Capacity Reserved For ERS Even with the clawback of the ERS Payment the ERS Generator will retain its ERS obligation throughout the ERS Standard Contract Term. September 15 QMWG Meeting 9 PUBLIC
