PJM presented several projects that it will recommend for approval at the Transmission Expansion Advisory Committee meeting at the April PJM Board meeting on March 8.
During the reliability analysis update, Aaron Berner, manager – Transmission Planning, said that PJM will open its next planning window as early as May but not later than June. It will be a 60-day window.
Berner discussed the “As Left” 2017 RTEP load deliverability study assumptions for the capacity emergency transfer limit locational deliverability areas and reviewed first reads of supplemental projects.
Berner also gave a second review of several supplemental projects, which PJM will recommend to the Board.
|Supplemental Jefferson Breakers
|Howard and Jericho Park 230 kV Breaker Replacement
|Calvert Cliffs Nuclear Power Plant Swing Transformer Upgrade
|Supplement Lisle 345kV Ring
|Supplement Wayne 345–138 kV Transformer 84 Replacement
Study of the market efficiency 2016/17 Long Term Window closed with a review of projects in the BGE transmission zone. PJM will recommend proposal 5E (page 5) for approval at the April Board meeting. PJM completed analysis on the PPL area and currently is not recommending any proposals.
The $25.40 million project had the highest cost among the proposals submitted for the BGE transmission constraints but it also most fully addresses the target congestion drivers at the Conastone-Graceton-Bagley 230-kV line.
