2017 Compilation Schedule change request Proposed to replace either: 2027-2028 HW1 – Planners needing a heavy winter case could update the 2026-2027HW1 case created in 2016, or modify the 2028HS1 case planned for 2017. 20XX TEPPC – Replace the TEPPC place-holder case with the 2028 Light Load case. Would reach out to TEPPC find out if this would be acceptable. 2021 LSP1-S – Replace this 5-year scenario case with the 10-year light load case. SRWG is checking with the requestor, to see if they might consider changing from a 5-year to a 10-year scenario. Talk to your PCC representative Western Electricity Coordinating Council
