Description
Duke Energy's Smart Grid Demonstration activities include work in the Envision Energy pilot in Charlotte, North Carolina. The Envision Energy project consists of two substation scale energy storage installations, a one MW solar installation, two community energy storage locations, communication nodes, distribution devices, metering, home energy management systems, residential PV, intelligent EVSE and plug-in vehicles. The residential systems (PV, PEV, EVSE, CES, HEM, and smart appliances) will be installed at five employee homes.
The Purpose of CES Systems is to perform transformer-level peak shaving by integrating with residential level distributed resources and loads. The CES units were reportedly shipped to Duke Energy in July 2011and installed at two utility employee properties in mid-September 2011. The units were previously observed being tested at a Milwaukee plant.
System components include:
-24 kWh, 24 kW Superior Lithium Polymer battery
-System integration module (S&C)
-Interconnection to customer side of distribution transformer.
