PJM considered alternatives to the Newark Switch project but concluded that a new substation adjacent to the existing structure was most cost-efficient. The project will cost $275 million.
“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,” PJM President and CEO Andrew Ott said in a statement.
PJM continues to evolve how it plans to consider new trends, said Ott. But “studying and planning for reliability remains the top priority.
PJM also approved equipment upgrades and improvements in areas served by American Electric Power; Dominion; Atlantic City Electric Co.; PECO Energy Co.; Pennsylvania Electric Company; American Transmission Systems; East Kentucky Power Cooperative; and Dayton Power & Light.
Most of the individual projects cost less than $5 million, the grid operator said. In the last 17 years, the PJM Board has approved $31.2 billion in transmission additions and upgrades.

Earlier this year, the board authorized a three-part project in PSEG’s northern New Jersey territory, to rebuild 138 kV lines in the Metuchen-Edison-Trenton-Burlington corridor, raising their capacity to 230 kV.
