Non Wires Alternatives

Moving Toward the Interactive Grid of the Future

Non-Wires Alternatives

We are committed to considering Non-Wires Alternatives (NWA) solutions to electric capital investments where they are appropriate and cost-effective, and supporting principles from the New York Public Service Commission’s Reforming the Energy Vision (REV) regulatory framework. NWA solutions utilize third-party Distributed Energy Resources (DERs) to postpone certain traditional construction projects needed primarily to correct system overloading conditions and in some cases, system reliability issues.

Strategy

Our strategy for NWA is to build a portfolio of NWA DER projects which are cost effective for customers, provide reliable alternatives to traditional capital investment projects, and provide full cost recovery and earnings opportunities for our companies, while we comply with regulatory directives and learn from and work cooperatively with other utilities and stakeholders.

Project Selection and Process

NWA solutions provide the opportunity to improve reliability, explore alternative infrastructure solutions and contribute to New York’s energy vision. To determine upcoming distribution and transmission projects suitable for these solutions, several factors are considered. Traditional electric system construction projects that meet a need for decreased demand and/or increased reliability, with a minimum of 36 months until time of need and construction costs greater than $1,000,000 are reviewed as potential NWA projects. Projects are evaluated and ordered according to time of need. Requests for proposals (RFP) are then scheduled and reviewed to determine cost-effectiveness and technical viability.

Upcoming Projects

Station 51

Station 51 Substation, located north of Rochester in our distribution area, is a reliability improvement project.  The station provides service to customers with significant loading.   If the station Transformer were lost the areas distribution system would not be able to support the load during the summer peak period. This project will increase station capacity and develop a second source contingency. The traditional wires project is to replace the existing 11-4.16 kV, 6.25 MVA station Transformer with a new 11-4.16x12.47 kV, 14 MVA LTC Transformer. The scope of work is to extend a new 34.5 kV line 773 to Station 51 and establish a new 34.5 kV transmission source feeding a second 34.5-4.16x12.47 kV, 14 MVA LTC station Transformer. We plan to release an RFP for NWA solutions in 2018.
