City of Naperville, Illinois Smart Grid Project

Jump to: navigation, search

The City of Naperville Utility will receive $10.9 million in funding from the U.S. Department of Energy to develop a smart-grid energy management system. The D.O.E. selected 100 companies nationwide to receive funding as part of the American Recovery and Reinvestment Act of 2009.[2]

The City of Naperville (Naperville) Smart Grid Initiative project involves a city-wide deployment of an advanced metering infrastructure (AMI) and an expansion of distribution automation capabilities, which includes circuit switches, remote fault indicators, and smart relays. Customers are allowed to purchase devices that assist in managing electricity use and costs, including in-home displays, programmable communicating thermostats, and direct load control devices for participation in load management programs. This project allows: (1) participants to view their energy use through in-home displays, a Web portal, or both; and (2) Naperville to manage, measure, and verify targeted demand reductions during peak periods. The new AMI and distribution automation technologies are intended to help improve service quality and reliability, by enabling outage management, distribution circuit monitoring, and automated circuit switching.[3]
