Based on recommendations from the Vermont System Planning Committee (VSPC) and direction from the Vermont Public Service Board, Efficiency Vermont implements energy efficiency efforts within specific geographic regions of the state to help relieve the electric load on constrained transmission and distribution systems and potentially defer the need for costly system upgrades.
Two geographically targeted areas have been established by the Vermont Public Service Board for the performance period of 2012-2014. The first is in the area of St. Albans, and it consists of approximately 1,100 commercial/industrial accounts and 5,900 residential accounts. The second is an area in Essex Junction and Colchester, and it consists of approximately 700 commercial/industrial accounts and 4,800 residential accounts.

A constrained transmission and distribution system is an area where the demand for power on the electric transmission and distribution facilities is at or near capacity during periods of peak demand. These peak demand periods typically occur during the summer on weekdays between 1:00pm and 5:00pm. As electricity demand increases, the need to take action—either to upgrade the electric transmission and distribution infrastructure or to reduce the load—becomes more critical.
Efficiency Vermont works with customers in geographically targeted areas to maximize reduction of summer peak demand. Load reduction efforts not only reduce energy costs for participating businesses and homes, but reduce the overall peak demand for electricity. These efforts benefit all electric ratepayers across the state by reducing expensive power supply purchases, and potentially deferring or avoiding the need for additional transmission and distribution upgrades.
