Modeling Work GroupDiscussion Points onFlexibility Reserves MWG Meeting December 05, 2011 Web Meeting
Proposed Agenda • Welcome, Introductions (Tom Miller) • Overview of Task • Discussion Topics • Overview of NREL Flexibility Reserve Calculations (Jack King) • Lessons learned from Ethree EIM Study (Arne Olson) • Modeling flexibility reserves in PROMOD (Stan Holland) • Modeling Issues and Options • Next Steps Discussion
Overview of Task • Background: Flexibility Reserves Webinar (DWG/MWG) & TAS approval to proceed • Overview of Task: • Model flexibility reserves in TEPPC studies to account for higher penetrations of variable generation • This effort will leverage the work performed by NREL and Ethree for the EIM Study • Stakeholder Participation: DWG, MWG, SWG, Topic Experts • PROMOD Expert (Stan Holland) • Proposal for December 15th TAS Conference call
Discussion Topics Presentations • Overview of NREL Flexibility Reserve Calculations (Jack King) • Arne Olson (Ethree): Lessons learned from EIM Study (Arne Olson) • Stan Holland (WECC Staff) : Modeling flexibility reserves in PROMOD (Stan Holland)
Issues and Options from Draft Scoping Document • ISSUE A- Granularity of Reserve Requirement • Options: Model Reserve Req. based on Daily Peak or Hourly Demand • ISSUE B: Modeling of Spin and Non-Spin • Option: increase operating reserves to include non-spin • ISSUE C: Fixed Hydro does not contribute to reserves • ISSUE D- Need for higher flexibility reserves to accommodate wind and solar resources • Proposed Option: Model composite reserves (contingency, flexibility reserves) on an hourly basis using data provided by NREL • Translation to TEPPC Topography
Next Steps • Flexibility Reserve Modeling • PROMOD 2020 Test Run using EIM study data for flexibility reserves? • NREL Flexibility Reserves Data • Translation to PROMOD • Data requirements and status to estimate flexibility reserve requirements for 2022 Case • Calculate flexibility reserve requirements TEPPC 2022 Common Case • Validation Team (Seeking Volunteers) • Flexibility Reserve Proposal to TAS • Other Tasks?

Proposed Agenda • Welcome, Introductions (Tom Miller) • WECC Activities Update (Stan Holland) • Today’s Discussion Topics • Modeling of Combined Heat and Power Resources Assumptions (Nick Schlag- EThree) • Modeling Validation and Calibration • California AB32 Sensitivity • Next Meeting
Modeling Validation and Calibration • TEPPC 2022 Common Case • Demand Response • Nomograms • Median Hydro • Demand Response • Hurdle Rates (2010 Case) • Sensitivity Cases • Wet and Dry Hydro • Flexibility Reserves • California AB32
Wrap-up and Next meeting • Wrap-up • Next meeting • Monday December 5th
California AB-32 Update • Promod run to test one set of case assumptions • Objective: Initial insights to modeling of CA as an “island” for CO-2 Cost • Leverage 2010 Study Cases for 2020: • PC3 High DSM • PC4 High DSM plus $30/ton CO-2 Adder • CA thermal CO2 cost adder = $30/ton • “CO-2” Cost Adder for CA imports increased by $13/MWh
Illustrative Example: Impacts to Economic Dispatch California AB32 Carbon Adders may impact interregional economic dispatch order Plant efficiency, CO2 $-Cost/ton and price of natural gas are key drivers to economic dispatch order
AB32 Case: WECC Re-dispatch California AB32 California dedicated coal resources displaced by Combined Cycle generation and coal generation not subject to full CO2 Cost Adder Today Case vs. AB32 Case (includescoal) CA Designated Coal
