TCAAP Energy Integration Resiliency Framework Policy White Paper – Energy Efficiency Strategies (Demand-Side Management) 31 6.2.2. Energy and Water Submetering Submetering can be used to measure separate energy uses (for example, lights or cooling) be yond the individual customer or building level in order to enhance feedback and management of efficiency opportunities. This management can occur in real-time, depending on the type of metering and communication. Water submetering is also included as many of the same savings benefits apply, and feedback to consumers could easily be bundled with energy. Reducing water pumping and treatment has environmental and energy savings benefits as well. This type of advanced infrastructure, like advanced metering, would be beneficial to enable many of the energy efficiency strategies described below, such as continuous commissioning or cu stomer feedback programs. Precedents San Diego Advanced Metering: San Diego Gas & Electric has implemented advanced metering across its entire service territory. Through an opt-out program they have installed 57,000 programmable controllable thermostats in homes and have reported over 98% customer satisfactory. This program has become a model for utility advanced metering infrastructure (AMI) programs across the country and prepares building and customers for possible future performance -based regulation.5 New Orleans Advanced Metering: The City of New Orleans provided match funding when Entergy New Orleans received a $5 million US Department of Energy smart grid grant. Starting in 2011, Entergy piloted an opt-in AMI program that outfitted customers with smart meters, online portals, in-home displays, and programmable thermostats. The utility and city partnered to garner strong community participation and engaged customers in a variety of training sessions. Overall, 58% - 67% of customers saved energy and at the end of the program 96% of participants wanted to be permanently involved in the program. On average, users reduced their total energy consumption by 6% - 8%. 6.3. Building Co-Location Building co-location is a demand-side management strategy that is uniquely appropriate for greenfield and large infill development. By considering the daily or seasonal timing of different types of energy use, site developers can facilitate buildings with complementary load schedules. Buildings with complementary heating, cooling, and hot water needs, or with inverse demand schedules, can be clustered to optimize use of energy resources. The primary benefit is more efficient utilization of small scale, onsite energy supply systems such as distributed solar or CHP. 5 Spotlight on Advanced Metering Infrastructure.
