PJM approves USD417 million transmission projects [free access]

August 7, 2017

The PJM Interconnection Board of Managers have authorised more than USD417 million worth of electric transmission projects for improving grid reliability. Among the largest is the replacement of a large, outdated substation that serves healthcare buildings, government, education, transportation centres and other critical infrastructure customers in Newark, New Jersey.


The Public Service Electric & Gas (PSE&G) has proposed to build a new 138/26 kV Newark gas-insulated switchgear (GIS) station in a building located adjacent to the existing Newark Switch Station and demolish the existing Newark Switch Station to replace aging equipment. A new substation adjacent to the existing structure was determined to be the most cost-efficient solution, at an estimated USD275 million.


The Board has also approved equipment upgrades and improvements in areas served by American Electric Power (AEP); Dominion Power; Atlantic City Electric Company; PECO Energy Company; Pennsylvania Electric Company (PEC); American Transmission Systems, Inc.; East Kentucky Power Cooperative, Inc. and Dayton Power & Light. Most of the individual projects cost less than USD5 million.


Since 2000, the PJM Board has approved USD31.2 billion in transmission additions and upgrades as part of PJM’s Regional Transmission Expansion Plan.
