NSTAR Electric & Gas Corporation ("NSTAR") is in the process of enhancing the grid monitoring instrumentation on one of its secondary area network grids, the Boston Area 492 North Grid, in downtown Boston, MA to provide unprecedented visibility into the operation of the grid. Using state-of-the-art sensor equipment along with a novel, low-cost approach to monitoring current and conductor temperature, NSTAR is in the process of greatly improving its understanding of grid status and behavior and allowing for proactive maintenance that improves safety and increases reliability. The visibility gained from this effort also offers the promise of increased capability for solar photovoltaics (PV) distributed generation (DG) injection. The results and knowledge gained from this demonstration will be broadly applicable to secondary area network grids in other urban areas across the U.S.
