Aggregated residential demand response using smart meters (21084)
The ability to curtail large groups (aka aggregations) of residential customer loads (i.e. air conditioning and electric hot water heaters) can be useful to NYS utilities to relieve strain and maintain reliability of the distribution system during a small number of hours a year that might otherwise require expensive infrastructure upgrades. Similarly, aggregated residential load control can provide wholesale demand response to better balance supply and demand on the grid. Smart electricity meters on homes may be used to enable the utility to directly control large residential loads in the homes of customers who are willing to have these occasionally curtailed.
Consert Inc., in conjunction with Central Hudson Gas and Electric Corporation (CHGE), will conduct a demonstration project involving about 200 residences equipped with Consert’s Virtual Peak Plant system, including smart meters and smart home equipment, to show how residential central AC and electric water heating loads can be controlled for demand response. CHGE believes it may be possible to delay or avoid capital investments to increase capacity of circuits that have experienced growth in peak loads through real-time load management and curtailment enabled by smart meters. Consert will investigate if and how this demand response may additionally be offered to the NYSIO demand response programs.
Consert’s residential system includes a Zigbee home area network (HAN) and direct load control (DLC) devices for major energy consuming devices such as water heaters and pumps, programmable communicating thermostats and a user web-portal with load automation functions and whole-home consumption feedback. Consert’s DLC devices include a measurement chip for measurement and verification of energy being used and curtailed by the equipment it is attached to. Consert’s portal allows residents to create dynamic profiles that automatically control thermostat and DLC device usage according to their preferences.
The benefits of this demonstration project include characterization and quantification of the amount for load curtailment that can be achieved with direct utility control of programmable communicating thermostats and residential AC in NYS. Similarly, data will be gathered on the curtailment potential from electric hot water heaters. The utility will have a resource that may enable them to avoid or postpone expensive infrastructure expenses. Finally, residential customers will have smart home equipment that will enable visibility to energy use via a web portal and automation of set points and schedules of HVAC and water heating via the portal. This project will also quantify any energy savings residents realize using this smart home equipment.
