PJM board approves $1B in new transmission projects

PJM Interconnection's board of directors approved about $1 billion of new electric transmission projects as part of its regional transmission expansion plan.

"Maintaining the reliability of the grid is paramount and involves continuously reviewing small and large transmission projects across our 13 states and the District of Columbia," PJM President and CEO Andrew Ott said in a news release.

The projects include new transmission lines and upgrades and to be in operation over the next 10 years. Several projects in New Jersey are in utility Public Service Enterprise Group Inc.'s service area. Other projects are located across Ohio, West Virginia, Tennessee, Kentucky and Virginia, a region served by American Electric Power Co. Inc. subsidiary AEP Transmission Holding Co. In Virginia, several projects are in Dominion Energy Inc.'s transmission zone. Other projects are in areas served by American Transmission Systems Inc., East Kentucky Power Cooperative Inc., FirstEnergy Corp. subsidiary Pennsylvania Electric Co. and in Duke Energy Corp.'s Ohio and Kentucky service territories, according to a Sept. 14 presentation that accompanied PJM's release.

While many individual projects cost less than $5 million a project, PJM's board approved a $197 million project in northern New Jersey to reinforce a 69-kV line by building a 230/69-kV switching substation in Springfield, N.J., and Stanley Terrace, N.J., both in Union County. The Springfield and Stanley Terrace substations are each connected to two underground 230-kV lines but additional support is needed to ensure that power demand does not exceed the delivery capability of the lines, according to PJM's presentation. Furthermore, the project involves building a 69-kV network to support the two stations. The solution is expected to be in operation in June 2018, PJM said in its presentation. Another $21 million project in Bergen County, N.J., bordering New York, will cover building a new 69-kV line in the county for operation in mid-2018.

A third project in PSEG's territory is estimated to cost about $98 million: a new 230/69-kV switching substation and two 69-kV lines in Gloucester County in southern New Jersey.

In Virginia, various projects by Dominion cost anywhere between $6.5 million and $40 million. One $40 million project looks to upgrade a 14-mile line on wood poles built in the 1970s to a double-circuit steel line. The project, expected to operate in 2022, is located in northeastern North Carolina.
