  1. 2024 Common Case Results Resource Adequacy

  2. What and Why • The resource adequacy check is a measure of a regions ability to meet its load requirements at time of peak using resources within each region and transmission constrained imports from neighboring regions. • TEPPC uses this check to indicate if there are adequate resources in the dataset as well as a check to not over build the dataset.

  3. List of Inputs • Sub-regional coincident peak demand • 2024 generation by area and resource type • Targeted planning reserve margin • On-peak coincident capacity value by resource type • Transfer capacity that could be used to eliminate deficits

  4. 2024 Generation • Renewable Resources • As needed to meet RPS targets • Conventional Resources • WECC class code 0-2 resources • Based on resource reconciliation efforts and stakeholder feedback • OTC replacement units

  5. Sub-Regional Coincident Peak Demand • Both summer and winter peaks • Extracted from the 2024 Common Case load forecast

  6. Planning Reserve Margins • LRS 2013 Power Supply Assessment LRS Power Supply Assessment Document

  7. On-Peak Capacity Value, Summer • Stakeholder input from past/current study programs • Current values pending SWG feedback

  8. Available Transmission Capacity Between Subregions • Based on path ratings • Accounts for transmission capacity used to reassign joint ownership plants • Limited so transfers do not exceed a subregion's surplus • Assumed wheeling from neighboring regions only

  9. Conventional generation added
