The PJM Board of Managers on Wednesday approved about $417 million in reliability-related transmission projects, more than half of which will go to Public Service Electric and Gas to replace a substation in downtown Newark, N.J.

“The board’s approval of these projects reinforces both PJM’s fundamental mission of preserving reliability and the value of PJM’s independent assessment of transmission needs,” CEO Andy Ott said. “Planning is evolving in PJM to consider impacts of new trends. However, studying and planning for reliability remains the top priority.”

The PSE&G substation rebuild is expected to cost ratepayers $275 million. A new gas-insulated substation will be built adjacent to the existing station, which will be torn down. (See “New Proposal Shaves $78M from PSE&G Switch Fix,” PJM Planning Committee and TEAC Briefs.)

The board also approved projects for American Electric Power, Dominion Energy, Atlantic City Electric, PECO Energy, Pennsylvania Electric, American Transmission Systems Inc., East Kentucky Power Cooperative, Exelon Generation and Dayton Power & Light. Most projects are estimated to cost less than $5 million, but a 31-mile reconstruction of a 230-kV line in Dominion’s territory is expected to run $31 million. Two ATSI reconductor projects are estimated at a combined $33.43 million.
