The transmission poles from the WAPA substation south of Groton to the Groton interconnect are in the process of getting changed out. The line is owned by Northwestern Energy and they wheel the electricity from the WAPA substation to Groton, then into the Northwestern Energy Substation that feeds Groton and the line also ties in to go to Webster and several other towns in between. The two-pole structure, pictured on the left, are being changed out to a single pole structure, pictured further back on the right hand side. There will be twice as many single pole structures to help carry the slack between the two-pole structures that were spaced further apart.  While the work is being done, power is being rerouted and Groton is being fed from the east.
