Meadow Brook to Loudoun 500 kV Line

Dominion is committed to providing reliable service to its customers now and in the future. The growing use of electricity in Northern Virginia has placed Dominion’s ability to meet its responsibility for its Northern Virginia customers increasingly at risk.

To overcome this risk, Dominion received permission to construct a new 65-mile overhead transmission line.

The company filed an application with the State Corporation Commission on April 19, 2007 for approval and certification of the line. In a unanimous decision on October 7, 2008, the SCC ordered that the $243 million Meadow Brook-to-Loudoun transmission project be built and operational by July 1, 2011. Dominion has now placed the line in service on time and under budget.

Project Details

Need for the Line

This transmission line is essential to Dominion Virginia Power's ability to maintain system reliability and support future growth in Northern Virginia.

  • The Northern Virginia Transmission System Review (KEMA Report) concluded there will be "significant problems in the system that will require new transmission facilities by 2011." P. Jeffrey Palermo, executive consultant with KEMA Inc., included the report in his testimony before the SCC to underscore the need for major new transmission system improvements in Northern Virginia.
  • Learn more about the KEMA Report and testimony (link provided below), and view related videos.
  • The stress on the system is well recognized. A study (The National Electric Transmission Congestion Study) conducted by the U.S. Department of Energy in August 2006 placed Northern Virginia in one of two national "critical congestion areas" for electricity transmission.
  • The DOE report stated that the region requires "billions of dollars of investment in new transmission, generation and demand-side resources over the next decade to protect grid reliability and ensure the area’s economic viability."
Community Relations

Below are interviews that voice support for the project:

Routes and Maps

The approved route follows within or adjacent to an existing transmission line right of way. The route would not claim any historic structures or any new land within state open space easements except where provided for in the State Corporation Commission's Order. By law, the route must reasonably minimize its impact on scenic assets, historic districts and environment of the area concerned.

Dominion’s Meadow Brook-to-Loudoun 500kV Transmission Line: Vital to Northern Virginia’s Energy Reliability and to National Security


An Urgent, Undeniable Need for a Solution in Northern Virginia

Northern Virginia’s transmission system could face severe overloads starting in 2011. These overloads could require drastic measures such as rolling blackouts. If left unchecked, it could lead to system failure and cascading blackouts.

KEMA, a well-respected, international firm that has served as a transmission consultant for the Virginia SCC, confirms the critical need for a transmission solution in Northern Virginia.  PJM concurs with this assessment. Even some opponents of the proposed line acknowledge the need for urgent solutions to Northern Virginia’s energy problems.

The U.S. Department of Energy has labeled the region a "critical congestion area" that faces "unparalleled problems." This line is needed by 2011 to comply with new, mandatory federal reliability standards.

Reliable Service in Northern Virginia Essential to National Security

Regional reliability issues could threaten national security. As former Deputy Assistant Secretary of Energy Edward Badolato said in Dominion’s application with the SCC, "Loss of power, and in particular, chronic shortages [due to] lack of adequate electric transmission capacity to Northern Virginia can have profound impacts on our national security."

The region is home to facilities such as the Pentagon, the CIA, and data centers for the defense, intelligence, and homeland security sectors. Major expansions include doubling the size of Ft. Belvoir and construction of a new U.S. Department of Homeland Security headquarters.

Badolato noted that power problems in Northern Virginia could have serious effects   throughout the entire National Capital Region (NCR). “Blackouts and loss of service…can impact emergency services, transportation, healthcare, building support, food supply and other non-defense components of the federal, state and local governments.”

Northern Virginia is also a critical component of the nation’s high-tech economy and information superhighway. No fewer than 23 new data centers — small campuses with a total electrical demand equal to a mid-sized city — are in the planning stages.

Other Solutions Not Feasible

Conservation and new generation, while helpful, are not feasible ways to solve the problem. By 2011, Northern Virginians would have to reduce their peak demand energy use by 40% to avert the need for the line. KEMA found this scenario "clearly not reasonable."

KEMA also found that meeting the need through new generation was not feasible.  This would require construction of "one of the largest [power stations] in North America" by 2011 in Northern Virginia. An even larger station would be needed by 2016, KEMA found.

Given the urgent nature of the problem and the critical importance of the region, Dominion must pursue solutions that are certain to work and can be in place on time.  The proposed transmission line is the only solution that meets these standards.


KEMA Report — " Northern Virginia Transmission System Review"

Background on KEMA

KEMA is an internationally recognized power system engineering firm with its American headquarters in Burlington, Massachusetts.  With more than 400 full-time professionals, KEMA has provided technical expertise and analysis for the entire range of stakeholder groups, from public utility regulators and commissions, to utilities, to private citizens.  For example, KEMA was retained by the State Corporation Commission in 1998 to evaluate Appalachian Power Co.’s proposed 765-kilovolt transmission line from its Wyoming Substation in West Virginia to its Cloverdale Substation near Roanoke. The line has since been constructed and energized.

KEMA was engaged to determine independently of Dominion if there is a need for major new transmission capacity in Northern Virginia and to evaluate potential solutions.

In maintaining reliability, utilities must examine worst-case scenarios that involve failure of major generation and transmission facilities.  If there is not enough transmission capacity to address these contingencies, the entire system can be put in jeopardy, with costly and potentially devastating consequences such as blackouts.

Testimony and KEMA Report

The testimony and report are part of Dominion's Application filed April 19, 2007, titled: "Application, Appendix, DEQ Supplement, Direct Testimony and Exhibits of Virginia Electric and Power Company Before the State Corporation Commission of Virginia."

  • Direct Testimony of P. Jeffrey Palermo, KEMA, Inc. (Review of need by KEMA, Inc.)
  • KEMA Report (complete report, attachment PJP-1 to P. Jeffrey Palermo Direct Testimony)

Summary of KEMA Findings

  • There is a need for action by 2011.  Without action, the transmission system in Northern Virginia would violate mandatory federal reliability standards by that year.  Major transmission lines serving Northern Virginia could become overloaded, resulting in potential system failure in the region.
  • No alternative to the new transmission line was found to have a reasonable expectation of meeting the need by 2011.  Further, "…the results show that either alternative (Dominion’s proposed and alternative routes) solves these problems in northern Virginia and the surrounding region." (p. 5)

Major Points in Study Analysis

The study evaluated 10 alternatives to solving the need by 2011, including demand-side management (DSM), new generation, and eight different transmission options.

Demand-Side Management Option

  • The nature of the transmission problem dictates that to reduce the overloading by 1 MW, Northern Virginia would have to reduce demand by approximately 12.5 MW.
  • Given this fact, Northern Virginians would have to reduce their peak energy use by 40% to avert the need for the line by 2011.  "To assume that such a program could be designed, approved, implemented, and accepted by DVP customers in less than four years is clearly not reasonable." (p. 61)
  • By 2016, Northern Virginians would have to reduce their peak energy use to almost ZERO to avert the need for the line.  KEMA determined this to be an unreasonable goal.

New Generation

  • Distributed generation options (solar panels on roofs, for example) could reduce the need; however, it faces the same constraints as DSM.  By 2011, the region would need 2,850 MW of new generation; by 2016, 6,975 MW, to meet the need.  KEMA compares this to adding 31,000 “neighborhood power stations” by 2011 and 77,000 by 2016.  KEMA sees this as unacceptable given the time constraints.
  • A single very large generating unit could meet the need; however, it would need to produce at least 3,000 MW by 2011.  To site, construct, and operate a power station this size in Northern Virginia by 2011 is unrealistic.  “This [solution] would require […] by far the largest plant in Virginia, and one of the largest in North America.  This plant would need to be even larger to be effective in 2016.” (pp. 62-3)
  • A few large plants could also meet the need, but would also require system improvements on transmission lines.  These plants would face the same challenges, with the added possibility of PJM cost penalties if these units were required to operate (for reliability) out of economic dispatch order.  “The costs of this out-of-merit order generation could be enormous.” (p. 63)

Other Transmission Options

  • KEMA conducted further analysis of eight transmission options; including overhead routes, an underground alternating current (AC), and a direct current (DC) option with portions underground.
  • "The first two options — the company proposed route and the alternate route — are very similar electrically and have better technical performance than the other alternatives.  The third option — HDVC (High Voltage Direct Current, with portions underground) — is acceptable but is not as good technically as the first two.  All of the other options are unacceptable." (p. 67)

The KEMA study confirms that serious reliability problems will result by 2011 if nothing is done in Northern Virginia. These problems require new transmission facilities by 2011, which the DVP alternatives meet.
