Overnight Testing Reveals Only Two Cables are Damaged
Hatteras Electric Cooperative’s (CHEC) continued transmission
restoration efforts last night revealed good news. Further testing at
the site of the Bonner Bridge incident indicates that only two of the
three underground transmission cables sustained damage.
The cooperative continues its execution of two simultaneous solutions
to restore transmission service. The underground solution is to
continue the excavation and de-watering process, digging to greater
depths to reach and splice the second damaged cable. Splicing on the
first damaged cable is complete. Installation efforts began early this
morning on the second solution – building a new overhead transmission
line that will run from the south end of the Bonner Bridge to meet the
cooperative’s existing overhead transmission
Restoring permanent transmission service as quickly and safely as
possible is CHEC’s top priority, which is why workers are aggressively
pursuing both solutions to determine which will be completed first. The
timeline for a complete repair ranges from one to two weeks.
The damage to the transmission cables occurred at the south side of the
Bonner Bridge early on the morning of July 27 when PCL Construction,
the company building the new Bonner Bridge, accidentally drove a steel
casing through the cooperative’s transmission cables. The cooperative
is supplying power to the island via permanent and portable diesel
generators, and while it pursues the permanent solutions, CHEC is
concurrently working to expand the temporary generation service on
Hatteras Island in order to accommodate a staged reentry of visitors. A
mandatory evacuation remains in effect for all visitors to Hatteras
Island at this time.
CHEC appreciates the continued support of its members, as well as Gov.
Roy Cooper and other officials from local and state agencies.
