Exhibit ___ (EIOP-19)Page 95 of 684heavily dependent on the monitoring and performance data to be collected after theinitial installations of the different AGA technologies. Similar to the reference modeldescription, this ranking model will be a living application changing as new and/or betterinformation becomes available.Drivers:There are numerous drivers leading to an increasing focus on Advanced GridApplications:• Regulatory/government direction which can be very specific and targeted. Forexample, the American Recovery and Reinvestment Act 0f 2009 (ARRA) offeredgrants for Smart Grid research projects or pilots. There are generally targetedareas as well with items like incentives for developers of Photovoltaic Generationfacilities, expectation of increased application of Demand Side Managementand/or Demand Response programs, and incentives for use of new technologiessuch as Plug in Electric Vehicles.• The evolution of external standards promulgated by FERC, NERC, NPCC,NYISO, etc.• Efficiency, reliability, and an increasing availability of the advanced gridtechnologies themselves, especially communications systems. The cost benefitof increased use of technology in lieu of traditional T&D system expansion isexpected to become more favorable.• Greater understanding of the benefits that Advanced Grid Applications deliver toour customers over the current methods of service and system design.Ultimately, it will be the ability of Advanced Grid Applications to economicallysolve system problems and meet customer service expectations that willdetermine the pace of their adoption and whether or not the Company executesdeployment in volume.Customer Benefits:Increasing the use of AGA technologies on the T&D system is expected to deliversignificant benefits to customers, including:• Enable more sophisticated control systems• Improve Reliability and Operational efficiency• Release system capacity• Promote the connection of more renewable resources such as electric vehicles(EV) and distributed generationThese AGA technologies are expected to result in an improvement in service quality forcustomers. This item has no direct regulatory impact but the projected reliabilityimprovements will aid in meeting future service quality targets.IV-19 1996
Exhibit ___ (EIOP-19)Page 96 of 6842011 to 2012 Variance:The projected investment is shown in the table below. This program was not funded inthe 2011 CIP.Table IV-14Advanced Grid ApplicationsProgram Variance ($millions)CIP FY12 FY13 FY14 FY15 FY16 FY17 Total2011 - - - - - - -2012 - - 5.0 5.0 5.0 5.0 20.0The scope and schedule of this project is still under conceptual review and is not yet aline item in the Plan. The Company is currently managing this item by evaluatingfunding shifts within the Plan considering reserves, and program placeholders forreactionary reliability issues such as Engineering Reliability Review.The following specific projects will exceed $1 million in any fiscal year:• Project Candidate, AGA, Clifton Park Area. This project will includeapproximately twelve 13.2kV feeders from multiple substations serving between22,000 to 25,000 customers and approximately 80 MW of load. Approximately60 advanced distribution automation switches and 50 advanced capacitor bankswill be installed along with a small number of both feeder and transformermonitors. This project is expected to improve feeder reliability, power factor andvoltage performance within the scope of the project. This location was identifieddue to the expected availability of a high bandwidth communications systembeing installed as part of the NY-ISO Capacitor Project.IV-20 2097
