The loss of the Barre to Berlin 115 kV line section, when heavily loaded from east to west, would overload the Berlin transformer. The transmission solution examined in the analysis conducted thus far is to install either a larger transformer or a second 115/34.5 kV transformer at Barre with requisite substation expansion. An alternative would be to sectionalize the underlying  network. This is primarily a bulk system issue that is the responsibility of VELCO and GMP. These constraints have been addressed by a proposal to automatically sectionalize the 34.5 kV system. Consequently no additional upgrades are needed at this time and no consideration by the VSPC will be required.

The map below shows roughly the area of Vermont potentially affected by this reliability deficiency.
