OVERVIEW of Mid-Atlantic Resiliency Link (MARL) 500kV / Gore - Doubs - Goose Creek (500kV)
MARL is part of the over $5 billion in new transmission lines approved by PJM to support the projected 7,500 megawatts of new data centers in Northern Virginia as well as to compensate for the planned retirement of 11,000 MW of fossil fuel generation in its eastern region.
MARL starts at the 502 Junction and is a giant extension cord from West Virginia’s coal fired plants - specifically the Fort Martin Power Station, Harrison Power Station and the Mitchell Power Station - into the ‘heart’ of Loudoun County's data center alley in Northern Virginia. All three of these generators are coal-fired and together total nearly 5,000 MW of capacity and according to PJM have excess capacity that can be tapped to support the development of new data centers (@117 )and expansion of the existing 200 data centers. Four transmission companies will be building segments of this line : NextERA, FirstEnergy, Dominion & PG&E across four states.
Both of the First Energy of power plants are reaching the end of their useful life within the next 10 to 15 years, at best this is a partial / temporary solution to the present energy shortfall in Virginia's data center region. A better solution would be for the Data Centers to locate closer to the generation plants with excess capacity or to build additional generation in Virginia to meet the demand.
PJM doesn't have a transmission reliability issue, the region has a lack of base load generation in Virginia issue.
If approved in all 4 states, this line will traverse :
NextERA 's portion of the transmission line is called Mid-Atlantic Resiliency Link (MARL) through :
Next ERA Project Maps can be found here: MARL Project Map
First Energy's portion of the transmission line is called Gore-Doubs-GooseCreek through :
First Energy Project Maps can be found here:
Note for Frederick and Montgomery properties in Maryland, south of Doubs - the project will result in there being 3 - 500kV and 2 - 230 lines in the ROW:
Dominion Energy is building a segment in eastern Loudoun from the Potomac River to the Golden Substation this segment is approximately 3 miles and will be entirely within the existing easement.
At the request of Loudoun County, PJM moved a portion of the transmission line farther out into northern western Loudoun County and into Maryland. The Alternate MARL Route was approved by PJM in August of 2024, this route crosses 15 miles of far Western Loudoun along the Potomac River crosses the Potomac River into Maryland and runs through Frederick and Montgomery counties in Maryland before crossing the Potomac River back into Loudoun County near Ashburn. This added $167M in cost, pushed the in-service date to 2032 and added the additional segments First Energy is to build through Frederick County and Montgomery County, Maryland
This transmission line will also cross the Monongahela National Forest, Appalachian National Scenic Trail, Chesapeake & Ohio Canal National Historical Park, Harpers Ferry National Historical Park, Potomac Heritage National Scenic Trail and it will run parallel down the view shed of the Potomac River.
Neither the MARL nor the Gore - Doubs - Goose Creek Transmission Line applications have been submitted to the VA SCC (as of July 28, 2025) nor have applications been filed in any other states.
Check out the Alerts & Action page for opportunities to participate, speak out , and make your voice heard!
If your property is impacted, get ready to intervene at the Virginia SCC by requesting an eFiling account. You do NOT need a lawyer you can intervene "pro se" and represent yourself!
There will be 8 transmission permitting cases across 4 states!

The Woodside substation is part of the MARL / Gore-Doubs-Goose-Creek Project.
The property purchased / proposed for the Substation is in Clear Brook in Frederick County, Virginia
NextERA could't have put together a fouler proposal if they tried.
Note at this time the Valley Link 765kV proposal appears to run past the Woodside Substation but does not appear to connect into it.

HVDC lines can be buried underground in a right of way that is only 5ft wide by 5ft deep and can be used for both long and short distances. In 2022 NextGen Highways did a feasibility study for Minnesota Department of Transportation for Buried High Voltage Direct Current Transmission. The study indicated the price has come down significantly and the installation space is smaller now. The study concluded buried HVDC is cost competitive.
There are about seven recent HVDC transmission projects on the United States many of which are either entirely underground or contain significant segments that are buried.

In 2009 During the PATH Case PJM Commissioned Black & Veatch to do a High Voltage Direct Current (HVDC ) Study to look at an underground alternative to the overhead 765kV HVAC transmission line.
There were two concepts. Concept 2 was to use HVDC Underground along the Mt Storm - Doubs line through Jefferson County, West VA and Loudoun County , VA and into Frederick , MD from Welton Springs to Kemptown, Maryland.
The same location PJM has proposed to locate MARL (500kV) and Valley Link (765kV) through Jefferson County, West VA and the Lovettsville / Neersville Area in Loudoun County
It would have cost 2x the overhead 765kV option back in 2009, since these transmission lines are needed for the data centers , the data centers should be required to pay the difference between the HVAC overhead option and the HVDC Underground Option. Underground HVDC is much cheaper than underground HVAC . Underground HVAC cannot be used for long distances , HVDC can. Also HVDC does not have the Electro-Magnetic Field (EMF) health issues that HVAC does.
There is no reason for pushing multiple massive 765kV and 500kV lines across thousands of acres of private property. Whenr the technology exists to put the lines underground.
PJM needs to be required to do an HVDC study for its multi-state transmission lines Valley Link and the MARL/Gore-Doubs-GooseCreek transmission lines in particular!

One of the reasons for the selected primary route for the MARL transmission line is to use an existing Appalachian Trail crossing. There are three highways (Route 7, Route 9 and Route 50) that also cross the Appalachian Trail to the south / south west of the existing Mt. Storm - Doubs transmission line crossing. "Data Center Alley" - the destination for all this power is on Route 7. Additionally, both Route 7 and Route 9 run directly to / towards "Data Center Alley". Using highway easements of any one of these would avoid taking private property to host the MARL transmission line. NextGen Highways advocates for using existing highway ROWs to co-locate infrastructure such as transmission lines ,they can be contracted with to study the feasibility of routing transmission lines along highways. In 2022 NextGen Highways did a feasibility study for Minnesota Department of Transportation for Buried High Voltage Direct Current Transmission. The study concluded buried HVDC is cost competitive.
This proposal impacts the Monongahela National Forest, Appalachian National Scenic Trail, Chesapeake & Ohio Canal National Historical Park, Harpers Ferry National Historical Park,Potomac Heritage National Scenic Trail and it will run parallel down the view shed of the Potomac River and will severely impact / destroy the scenic and historic value of these assets.
The MARL/ Gore Doubs-GooseCreek project follows a portion of the same route as the 2010 PATH Transmission line (which was defeated) along the Mt-Storm - Doubs transmission line through West VA and Virginia into Maryland. In 2010 National Park Service did a scoping analysis and an Environmental Impact Statement .
In addition , the segment through Garrett and Allegheny Counties in Maryland expands the easements in Big Savage Mountain Wildland and Bear Pen Wildland by 200' and adds a new 200' easement through Dan's Mountain Wildland (See comments to the MD General Assembly below)
These are the sections from the PJM Regional Transmission Expansion Plan (RTEP) for MARL/Gore-Doubs-Goose Creek. PJM is the Regional Transmission Organisation (RTO) that covers Virginia, West Virginia, Pennsylvania and Maryland. This organisation manages the grid and the planning process for interstate transmission lines as well as overseeing the capacity market for the region. The PJM Board Of Managers approves the transmission line proposals at the regional level and then the proposals go to the states to approve.
