TCAAP Energy Integration Resiliency Framework Policy White Paper – Energy Efficiency Strategies (Demand-Side Management) 32 Figure 1. Example time-of-day electricity demand for different customer segments Co-location can be additionally beneficial when planned in conjunction with future customer rates that might reflect time of use or real-time demand costs. Such rates will provide cost signals to help direct the time of day or week when energy is consumed. While building co -location requires advanced planning, this can also be used to coordinate planned maintenance to share costs. 6.3.1. Complementary Thermal Loads Complementary thermal loads come from customer types that use (or perhaps through feedback can be encouraged to use) thermal energy at different times of day. For example, buildings that are occupied, and therefore heated, at different times of the day or week. Complementary thermal loads can also include buildings or processes with high thermal requirements, such as laundry facilities, which can ensure use of waste heat resources from CHP throughout the year. Attracting such high heat customers as anchor loads and locating them on strategic points throughout a thermal supply network can lower unit costs of energy for all users. 6.3.2. Complementary Electrical Loads Similar to thermal loads, complementary electric loads come from customers that use electricity at different times of the day or season. Unlike thermal energy, electricity cannot currently be stored at low cost. Complementary building types can help lower the needed capacity of any on-site electricity supply technologies, and also amortize the cost over a larger number of electricity sales. Examples of complementary loads might include mixing weekday and weekend operations, or a high concentration of EVs that are charging overnight.
