Regional transmission organization (RTO) PJM Interconnection has approved a $1.5 billion budget to improve electric transmission infrastructure in its 13-state and Washington, D.C., coverage area.
The RTO has authorized funding for projects to provide better power supply for roughly 65 million customers, Kallanish Energy finds.
"The growing need to replace aging infrastructure, energy efficiency and the resulting reduction in the growth of demand for electricity are affecting transmission development,” said Andrew Ott, PJM's chief executive.
The largest project approved will replace aging infrastructure – in some places more than 80 years old — in New Jersey’s Burlington, Mercer and Middlesex counties, in addition to reconstructing portions of existing transmission lines.
The PJM board approved a three-part project to reconstruct and upgrade to 230-kilovolt (kV), the existing 138kV lines in New Jersey’s Metuchen-Edison-Trenton-Burlington corridor.
These projects are located in the service areas of Metropolitan Edison, PP&L, PSE&G, American Electric Power, Dominion, and Duke Energy Ohio/Kentucky.
Since 2000, the power grid operator has authorized roughly $30.8 billion in transmission additions and upgrades.
PJM operates the power transmission system in all or parts of Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia, and the District of Columbia.
