New Milford, CT: Smart grid company Demansys Energy LLC announced February 13 that it had begun operation of a 75 MW aggregate of real-time, demand-side resources in New York through a New York Independent System Operator (NYISO) program. Demansys uses its proprietary Grid Daemon Platform to aggregate and control in real time the load of commercial and industrial customers in order to provide energy, reserves, and regulation to the wholesale markets, alongside traditional generation.
The NYISO’s DSASP program permits the aggregation of end-use customers to provide ancillary services to the power grid by controlling them using a supervisory control and data acquisition (SCADA) system. The Demansys system responds to automated generator control (AGC) signals from the grid operator, leveraging the same technology used to control traditional power plants. The grid operator sees these resources as just another supplier to the grid. Using sophisticated, proprietary algorithms, Demansys can predict the availability of the individual loads in the aggregate and optimize how they are bid into the wholesale markets.
Managing energy assets in real time, the Demansys. Grid Daemon platform adjusts the energy usage of commonly-used equipment and storage resources, without negatively affecting process or product, in order to provide reliability services to the grid operator. Demansys has been testing its technology in the Alternative Resource Regulation Pilot in New England since October, 2012.
Through a contract signed last year with the IESO, Toronto-based ENBALA has been providing a similar service to the Ontario grid.
