Reference: n/a Assessment Score: Recommend Program Oescrip~on: The Company's Distribution Grid system includes 18,000 circuit miles of overhead and underground primary conductors. As load and generation patterns shift, certain areas (segments) of the system become thermally overloaded. These constrained portions of the system are identified through systematic planning studies or from operational studyworks conducted by Area Engineers. In addition, FDR 'Tie' switches are installed to allow load shifts between FDR circuits to balance loads and in response to either maintenance or forced outages. (rev 8/11/16 --- a portion of the "Worst FDR"program will be incornorated with this nro.,ram. Startin" in 2017 $1M will be added to Seement Reconductor and Alfefnatlve.s; Unfunded Program: Avista's Distribution System Planning criteria (e.g. 500 A Plan) mandates performance levels for distribution circuits including capacity and voltage requirements. This program is aimed at maintaining compliance with planning criteria.
