ComEd Power Curtailment Plan: Guidelines and Procedures for Summer Events

This document outlines the ComEd Power Curtailment Plan, effective between June 1 and September 30, primarily in August, concerning normal workdays. It details how to manage power reductions of over 15MW, including a two-hour warning period and the invocation of Plan "A." Key operations involve shutting down specific power supplies and managing load requirements to maintain lab operations efficiently. Participation in curtailment events is voluntary, with a maximum of 15 actual events permitted, each lasting up to 8 hours. Strategies for minimizing impact on ongoing services and communication protocols are also included.

One Time, One Hour Test • Between June 1st and September 30th • Usually in August • Normal Work Days • 2 Hour Warning By Contract (2 days?) • Invoke Bob’s Plan “A” & drop >15MW • New criteria is to get lab to 43.5 MW to break even. (46.5 MW we owe $120k, $40k/MW) • Labs Running at ~61MW (Drop 17.5MW)

  3. Plan “A” • Turn off Main Injector and Booster as if they were going into access. • Turn off (stop ramping) Switchyard, NuMI, MiniBooNE, PBar, and any other power supplies since beam will be unavailable. • The Tevatron Store will remain circulating, if we have one. • The Stack (PBar) and Stash (RR) will also remain circulating.

  4. Plan “A” Continued • No New Bakes or large power loads added at IB-1, IB-4, NML, MP9, or other areas. • Call Division/Section Contacts (Update Contact List)
