GRID: Energy conservation helps stymie a major transmission line

Peter Behr, E&E reporter

    Transmission projects have traditionally come under attack by
    environmental, scenic and "not in my backyard" partisans. Now a major
    mid-Atlantic power line proposal may be held up instead by a weak economy and a
    growing energy conservation movement.

    A Virginia regulatory examiner plans this week to rule on a request by PATH
    Allegheny Virginia Transmission Corp. to withdraw its proposal to build a
    276-mile, $1.8 billion high-voltage transmission line from West Virginia
    through Virginia's northwest corner to a proposed substation near Frederick,
    Md. The project would be resubmitted this fall, its backers say.

    A hurried analysis over the weekend between Christmas and New Year's Day by
    the PJM Interconnection, called for by the Virginia State Corporation
    Commission, indicated that the PATH line was not required in June 2014 to keep
    lights on the mid-Atlantic region. PJM had called for the 2014 completion date
    last April, in its regular yearly study of transmission needs.

    The new planning scenarios "suggest that the PATH Project appears not to be
    needed in 2014," said Steven Herling, PJM's vice president for planning, in a
    Dec. 28 letter to the project's developers, American Electric Power and
    Allegheny Energy Inc.

    The two-year-long recession had already caused PJM, the mid-Atlantic grid
    operator, several times to push back its forecast of when the line would be
    needed to meet reliability requirements. The new element that figured in PJM's
    latest analysis was the recent sharp increase in demand response offers --
    commitments by businesses and some pooled residential customers to cut back
    electricity usage when power shortages threaten, in return for compensation by
    utilities.

    "Clearly, the big impact of the delay [in last spring's forecast] related
    to the economy," Herling said in an interview. "The analysis we did at the
    beginning of 2009 was based on load forecast that included the recession. That
    pushed the line to 2014." Last month's analysis added demand response, and that
    showed that the line was no longer required in 2014. "Demand response is having
    a significant effect," Herling said.
    Energy conservation kicks in to ease reliability worries

    The outlook was direr in 2007, when the line was proposed, according to the
    companies. "The PATH project addresses significant reliability concerns in the
    region, including overloads that will occur on more than thirteen existing
    transmission lines in Maryland, West Virginia, Virginia and Pennsylvania, as
    soon as 2012 if PATH is not built," AEP chairman Michael Morris said in a
    release in December of that year.

    Environmental organizations and property owners in the line's right of way
    said the new PJM analysis confirmed what should have been obvious -- that the
    economic slump and efficiency and conservation initiatives were undercutting
    the need for the line.

    "We knew the economy was lousy last spring. We knew these efficiency
    measures were in place. They have been ignoring the facts right along," said
    Malcolm Baldwin, who owns a farm in Lovettsville in Loudoun County, Va., and is
    a board member of the Piedmont Environmental Council. The council opposes the
    PATH project and a second major project, the TRAIL power line that is now under
    construction from West Virginia to Northern Virginia.

    PJM's new preliminary analysis indicates that because of reduced demand,
    key high-voltage power lines into Maryland and northern Virginia aren't
    threatened with overloading until 2021 or later, based on assessments of how
    much power they can safely carry. Herling said reliability limits on voltages,
    however, could be reached in the region as early as 2016.

    Herling said PJM won't have a firm fix on when the PATH line is required
    until it completes its next annual detailed assessment in June.
    Multi-state confusion results

    The new forecast has added confusion to an already clouded regulatory
    picture in the three states that would be linked by the proposed line --
    Virginia, Maryland and West Virginia. The project is under review in West
    Virginia. The Maryland Public Service Commission dismissed the PATH application
    on Sept. 9 last year, finding that a new entity created to operate the line in
    Maryland didn't meet state requirements. Potomac Edison, a unit of Allegheny
    Energy, has refiled under its own name, and the Maryland PSC has a hearing
    scheduled today to consider the new filing.

    "I'm anticipating a discussion and numerous questions [from the
    commission]. They need get much more detailed information from Potomac Edison
    as why they are moving forward at this time given the activities" the utility
    is undertaking in Virginia, said Paula Carmody, Maryland's people's counsel.

    On Dec. 21, Potomac Edison submitted testimony from PJM experts declaring
    that the line would be needed in 2014. Potomac Edison notified the Maryland
    commission of the new PJM finding on Monday, asking that the commission hold
    its review open until this summer, when the full PJM assessment is done.

    In Virginia, the PATH opponents are asking state regulators to reject the
    project outright. "The application should be denied. They've admitted they
    don't need it," said Wil Burns, an attorney for the Sierra Club. The Virginia
    State Corporation Commission's staff also urged the commission to dismiss the
    PATH project based on Maryland's rejection.

    The Virginia staff said that if the review remains open, it could invite
    intervention by the Federal Energy Regulatory Commission, which could order the
    line to be built backed by federal eminent domain authority. The 2005 federal
    energy act permits FERC to direct the construction of high-priority
    transmission lines if states fail to act on proposals within one year. The 4th
    U.S. Circuit Court of Appeals ruled last year that FERC could not step in if a
    state commission rejected a transmission project, however.

    PATH told Virginia regulators that it will not ask FERC to intervene in the
    case.

    PJM's changed forecasts may illustrate the uncertainties about projecting
    grid requirements, as the power industry heads into a future of smart grid
    innovations, growing renewable power flows, more conservation and demand
    response policies and proposals for carbon emission legislation. "Changing
    circumstances may make the proposed project vitally needed to maintain
    essential utilities services," said Alexander Skirpan Jr., senior hearing
    examiner for the Virginia commission, last November.

    PATH's opponents protest that the line will bring more coal-fired electric
    power into the Eastern Seaboard. Companies promoting new lines say they will
    also carry wind, nuclear or natural gas-fired generation, and the economics of
