Project Need

  • This project resolves PJM requirements as identified in 2014-15 PJM RTEP Market Efficiency Study. This project is required for BGE to meet its obligations under the Operating Agreement with PJM
  • This project resolves transmission system congestion and reduces associated congestion costs in the PJM market, thus providing economic benefit to BGE customers
  • This project was selected by PJM as the best solution for reducing transmission congestion on this portion of the system

Project Description

  • The scope of work includes reconductoring / rebuilding the two Conastone - Reisterstown 230 kV transmission lines to increased ratings, and alterations to the Conastone Substation to accommodate the increased line rating
  • Overall project length is approximately 25 miles
  • This project is subject to PSC approval and design changes

Photo Simulation

Photo taken from Dover Road looking northeast. The majority of the project will consist of reconductoring the two Conastone - Northwest 230 kV lines. Reconductoring is replacing old transmission wire with new transmission wire. Six existing lattice towers will be replaced with steel poles. This photo simulation demonstrates the before and after conditions of one of those structure replacements. This project is subject to PSC approval and design changes.
