Vermont’s Southern Loop/Coolidge
Connector
Vermont Electric
Power Company (VELCO) was coming
off a transmission line
improvement project that had not
gone well at all. Regulators had
felt backed into a corner in
approving the project, and
legislators and members of the
public were extremely angry.
Unfortunately for
VELCO and its largest owner,
Central Vermont Public Service
Company (CVPS), transmission
upgrades were desperately needed
in another part of the state as
quickly as possible. Demand in
the southern part of the state
along CVPS's 49-mile, 46kV
transmission line (the "Southern
Loop") had grown to the point that CVPS was unable to perform even routine maintenance without running the risk of causing wide-spread outages across the entire region.
Worse, problems with the
Southern Loop were directly
related to a larger, state-wide
reliability challenge facing
both CVPS and VELCO: the need to
reinforce the state's main
transmission "backbone" by
constructing a new, 51-mile,
345kV line through a heavily
forested area (the "Coolidge
Connector").
Using our Utility
Search Conference®
process, STAR Group convened
stakeholders representing
diverse interests throughout the
region. At the conclusion of the
2-day event, participants
(which, as always, included
engineers and other utility
representatives) proposed a
series of innovative
recommendations. CVPS was asked
to move forward “immediately” with
the installation of 2 new synchronous condensers
that would regulate voltage
along the 49-mile transmission
line, thereby deferring the need
to rebuild that line.
Stakeholders also recommended
that CVPS and VELCO construct
the Coolidge Connector, which
would be the largest
transmission line infrastructure
project in Vermont's history. In
addition, the two utilities
pledged to work with
stakeholders to implement new
demand side management and
renewable energy projects.
The Vermont
Public Service Board, citing the
extensive public outreach
efforts used by VELCO and CVPS,
approved the entire
complement of transmission
upgrades, including the Coolidge
Connector. Equally important,
the companies have obtained
regulatory approval for and are
in the process of implementing
several of the non-transmission
recommendations developed by
process participants, including
solar, biomass, combined heat &
power and demand-side reduction
projects across the state.
The results
achieved by VELCO, CVPS and
their stakeholders demonstrate
clearly that STAR Group's
Utility Search Conference®
process will produce positive
outcomes that all will support,
even in hostile environments
where the utility does not enjoy
a high level of trust with
regulators or the public.
