Norwich — The main Taftville intersection at routes 169 and 97 will look a little different soon.

The city is seeking bids for the demolition of an electrical substation that has sat at the intersection for 60 years. The gray fenced-in boxy structure at 8 Providence St. was taken offline by Norwich Public Utilities in April as part of an overall electrical upgrade project, NPU spokesman Chris Riley said.

NPU’s other distribution substation on North Main Street also is scheduled to be removed from service within the next three years, Riley said.

“Both Taftville and North Main Street substations operate at a lower voltage, which is being phased out as part of our long-term capital plans focused on modernizing our electric infrastructure,” Riley said.

NPU’s three remaining substations — 10th Street in Taftville, Dudley Street, and Bean Hill — operate at a higher voltage, which increases the efficiency and eliminates the need for the smaller distribution substations, Riley said.

Bids for the demolition of the Taftville substation are due Sept. 9.
