Hatteras Electric Cooperative and contract crews have simultaneously
pursued two options for restoring permanent transmission service to
Hatteras and Ocracoke Islands, waiting for one solution to emerge as
the fastest, safest way to restore reliable transmission service. That
determination has been reached.
Solution: Constructing a new overhead transmission line from its
underground point at the south end of the Bonner Bridge to the point
where it meets the cooperative’s existing overhead transmission line is
the most expedient way to restore transmission service to the islands.
CHEC reached this determination in consultation with specialty contract
crews including Lee Electrical Construction, an organization that
specializes in high-voltage transmission line construction, and New
River Electrical, which specializes in the highly complex processes of
splicing and transitioning lines from underground to overhead.
Overhead Progress: Crews
began installing the three-phase line last night. Concurrently, the
specialist team from New River Electrical is executing prep work for
creating the transition from underground to overhead just before the
site of the damage and creating connections to the existing overhead
lines that run the length of Hatteras Island.
Underground Situation: Despite
PCL Construction’s tireless excavation efforts and attempts to dewater
the trench at the site of the damage, trench conditions proved to be
too challenging for the underground solution to be viable. PCL
Construction was able to reveal all three cables, but water continued
to seep into the trench making the environment unsuitable for repairs.
restoration timeframe from this point forward is 3-5 days. This
includes the time required for testing after all construction is
complete and before transmission service can begin. CHEC is also
working with Dare County officials to coordinate the safe return of
visitors as soon as possible
There are many people, partners and businesses we would like to thank.
We are very appreciative of the support of our members, visitors,
contract crews and PCL Construction for leading the excavation.
