Customer – Sustainability Hub We are working with local colleges and Universities to build a Sustainability Hub for the pilot This location will house the pilot’s college co-op interns, offer a place for customers to have a person answer their questions, showcase some of the new technology and offer meeting space for community organizations working on sustainability issues

  10. Results To Date • Early Field Trial (EFT) meters in place since March 2012 • 5,000 meters • Tested communications • Tested reading of meter data • 299 customers opted out of meter (5.97%) • Remaining 10,000 meters scheduled in service by May 31, 2013 • Pilot start date scheduled for January 1, 2014 • Provides 2 years of baseline data for summer use for 5,000 customers and one year for 10,000 meters
