Baseline Reports PJM’s Regional Transmission Expansion Plan (RTEP) assesses both near-term five-year needs of the regional power grid as well as those over a 15 year horizon as well. The results of these “baseline” studies identify needed transmission enhancements for anticipated system conditions and define cost allocation assignment. The five-year baseline then provides a starting point from which the need and responsibility for enhancements to accommodate interconnection requests can be identified.
