Transmission Owner Technical Guidelines & Recommendations below, formerly were referred to as the “PJM TSDS Technical Requirements”, as published by the PJM Transmission & Sustation Design Committee (TSDS).
The documents included here are still subject to PJM's review and may thus potentially change before being formally published pursuant to Section 1.2c of the
PJM Open Access Transmission Tariff (PDF).
These documents were originally developed for PJM by TSDS member companies when PJM’s footprint matched the
NERC MAAC Region (contributing companies included AE, BGC, DPL, JCPL, MetEd, PECO, PENELEC, PEPCO, PPL and PSEG.) Many of these companies often reference these documents for their Technical Requirements and Standards as defined in the PJM OATT. PJM now extends into multiple
NERC regions. New members typically reference their own documents and therefore these documents no longer represent all of PJM. However, all PJM members are welcome to reference these documents.
