A revised proposal for a substation used to power the Cobbs Creek Reservoir is set to be heard by the Cumberland County Planning Commission Monday.

The revised proposal moves the location of the proposed substation by 200 feet. The substation is proposed to be located in the area of 1617 Cartersville Road.

“Central Virginia Electric Cooperative (CVEC) has applied to build a 115-(Kilovolts) KV transmission tap line that would be around 2,100 feet long, and lie within a 100 foot easement provided by Henrico County,” the board packet for a past commission meeting cited. “They are also proposing to construct an electric substation on a 110’ by 150’ (foot) site owned by Henrico County. The substation would serve the Cobbs Creek Reservoir pump station as well as 475 customers of CVEC.”

The initial application was recommended by the commission in July and approved by the Cumberland County Board of Supervisors during the board’s August meeting.

A memorandum of understanding between Cumberland County and Henrico County was agreed to in 2010 for the Cobbs Creek Reservoir, and Henrico began the first phase of building its reservoir in 2015.

The reservoir is estimated to cost $280 million and expand 1,117-acres, encompassing a little more than 15 miles of stream bed, according to a Virginia Department of Environmental Quality (DEQ) permit. It will permanently impact 15.3 miles of stream, almost 31 acres of wetlands and 4.6 acres of open water.

The reservoir would collect water from the James River.

The application cited that the substation will be unmanned, but will have monthly inspections.

“CVEC personnel will be on-site for maintenance activities as needed,” the application cited about the substation.

“The transmission line will consist of steel monopoles ranging in height above ground between 88’ and 102’ (feet),” the application cited. “The substation will consist of various steel structures with the tallest structure 73’ above ground.”
