      Another fight over power lines underway in Minnesota

    *Hearings are under way around Minnesota this week about a new set
    of power lines proposed for the state. This is the first major
    transmission line project since the mid-1970s. The utilities
    proposing the project say the lines are needed to make the electric
    grid more reliable, and to lay the groundwork to supply more power
    to Minnesota homes and businesses. *

    St. Paul, Minn. — Eleven utilities have been working on the
    so-called CapX 2020 project for four years. The companies are
    determined to avoid the bitter controversy that plagued the last
    major high-voltage power line project, they say. That project was
    built in central Minnesota in the late 1970s. In those days, farmers
    were so angry at the power companies, they cut down power poles and
    blocked the project in other ways.

    This time, the utilities have set up a huge public relations effort.
    They mailed notices to more than 70,000 people along broad corridors
    where the lines might travel, warning them the planning process is
    underway.

    The four new high-voltage lines would make the electric grid more
    reliable, especially in parts of the state where the population is
    growing, says Laura McCarten, Xcel Energy's Director of Regional
    Transmission Planning, who also helps direct the CapX initiative.

    "Because of the customer growth, we need new source, new pathways,
    to deliver electricity in areas like St. Cloud, Rochester,
    Alexandria: that without building something, those communities are
    at risk of reduced reliability."

    One line would run from Fargo North Dakota to St. Cloud and
    Monticello. Another would run from Brookings, S.D. to the southeast
    metro area. A third would run between the Twin Cities and La Crosse,
    Wisc. A much shorter line would connect Bemidji and Grand Rapids.

    All these lines are designed to move power from existing generating
    plants to existing homes and businesses.

    But at least one long-time critic of the electric power industry in
    Minnesota argues the utilities are working the wrong way.

    George Crocker, who directs the North American Water Office, a group
    that got its start back in the power line fight of the 1970s, has
    long promoted the idea of distributed generation -- small amounts of
    power from small producers like windmills, that could spring up all
    over the state.

    A study just published this week shows utilities could add power
    from distributed generation to the lower-voltage lines that already
    criss-cross Minnesota, he says.

    "Think of how a river forms. It's because all of the little rivers
    join the big river. It's not the big river telling the little rivers
    where to go; it's the little rivers that tell the big river where to
    go. It's the same with power if we do it smartly."

    The lower-voltage system can collect small amounts of power, and add
    it to the high-voltage system, where it would ultimately travel to
    where it's needed, he says.

    That method is simpler and quicker and cheaper to add both
    generation and transmission at lower power levels. Crocker predicts
    the study -- called the Dispersed Renewable Generation Transmission
    Study -- will change how we get energy.

    "When the value of this type of thinking percolates into the
    management of how utilities operate, we won't even be thinking about
    CapX-type development anymore. This is a real deal that I am
    absolutely certain we will not pass up."

    Not everyone sees the report the same way, though.

    Adding small power plants anywhere along the line affects the entire
    grid, says Jared Alholinna, transmission planner at Great River
    Energy, who helped write the report.

    "The system east of the Rockies is all connected and the electrons
    don't always flow in a straight path. Let's say from a generation
    plant to the Twin Cities it takes circuitous paths, sometimes as far
    north as Manitoba, and sometimes as far south as Nebraska, in making
    its way back up, but that's what leads to regional reliability in a
    transmission grid."

    There has to be enough high-voltage power lines to accommodate added
    power, he says.

    "Just like congestion on a freeway, one of the ideas is that you
    build a bigger freeway, so you can accommodate more cars and there's
    less congestion. Especially when generation tends to travel further
    distances."

    The power lines proposed in the CapX 2020 project are needed now,
    the utilities say. They're planning a second and third phase, and
    they'll start talking about those next year. Meanwhile, they're
    preparing environmental studies on CapX. The Minnesota Public
    Utilities Commission will rule on whether the lines are needed in
    the fall. Construction is not scheduled to start until 2010.

Medicine Lake trail bridge is, uh, shocking

Literally. Bicyclists have reported electrical shocks crossing the
Maple Grove bridge. MnDOT says no one is in danger.

Shocked by the new bridge on the Medicine Lake Regional Trail?

Some bikers were, causing the Minnesota Department of Transportation
to shut down the bridge leading into Elm Creek Park Reserve over
County Road 81 in Maple Grove.

The bridge, which opened last fall, is expected to re-open next week
with additional grounding support to prevent shocks. It was closed on
June 16 after a handful of complaints.

"It felt like insects fluffed my bicycle shorts," said Kris Siejko, a
cyclist who has experienced the shock numerous times.

According to MnDOT spokesman Kent Barnard, nobody on the biker and
pedestrian bridge was in danger at any point and that the shocks only
caused discomfort.

Barnard said the shocks appear to be connected with nearby power
lines, although both the bridge and the power lines were all built
within specifications.

"We are operating under the assumption that part of what is happening
is that people themselves are getting charged as they are traveling
underneath [the power lines] and they are discharging to the bike and
rail," Xcel Energy engineer Benjamin Gallay said. "There's nothing
significant we can do to stop that other than telling people, 'No, you
can't walk there.' "

Gallay said that even with additional grounding, riders may still feel
a bit of the sensation.

Siejko, an electrical engineer at Boston Scientific, said it felt like
a current ran through his bicycle seat every time he went underneath
the power lines on the bridge. "Eventually I just started riding
standing up," he said.

Barnard said the department has dealt with similar issues before, and
that if additional work on the bridge is necessary, they will look
into it.

He also said MnDOT will pick up the tab for the project, and though no
cost figures are available, "we are not looking at it costing much
money."

Three Rivers Park District spokesman Tom Knisely said his office has
received three complaints about people getting shocked. The first
complaint came in early April, another came in mid-May and by Siejko's
complaint in early June, the park system sent a specialist to have a
look.

After complaints were confirmed on June 13, the park notified MnDOT
and re-routed traffic to a nearby crossing. MnDOT officially closed
the bridge three days later.

One complainant said he felt "a zap in his left leg." Another said "a
current tingles my fingers" every time he crossed under the high lines
on the south side of the bridge.

Barnard said work was done via a partnership among MnDOT, Three Rivers
Park District and Xcel Energy.

Detour signs are now in place advising trail users to cross at the
controlled intersection at Fernbrook Lane.
