PGRR134  Interconnection Studies Reform for Dispatchable Loads

This PGRR allows Interconnecting Large Load Entities (ILLEs) to submit an NPRR1188-compliant Controllable Load Resources (CLR) election to the reviewing Transmission Service Provider (TSP). TSPs treat the election as a CLR Election Study input, model the site as an NPRR1188-compliant CLR, and may authorize earlier energization when constraints can be mitigated by dispatch down to the CLR Low Power Consumption (LPC), which may equal zero for the CLR. All Load would still be studied for delivery of their full capacity with timelines for firm network service outlined in the Load Commissioning Plan (LCP). Additionally, this PGRR directs that each proposed Large Load that elects to be studied as a CLR will be studied using the LPC and Maximum Power Consumption (MPC) provided as part of project information described in Section 9.2.2, Submission of Large Load Project Information and Initiation of the Large Load Interconnection Study (LLIS). It further directs that for the purposes of the Large Load Interconnection Study Methodology, CLRs will be studied assuming registration and qualification under NPRR1188 or any successor provision. Finally, this PGRR prohibits a CLR from using this program if it would impair a previously submitted Large Load’s requested energization date or energization capacity and that ERCOT may specify Interconnection Reliability Operating Limits (IROLs) or other reliability related transmission limits which cannot be resolved with CLR dispatch.
