Smart grid company Demansys Energy LLC has 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 says it is utilizing its proprietary Grid Daemon Platform to aggregate and control the load of commercial and industrial customers in real time in order to provide energy, reserves and regulation to the wholesale markets alongside traditional generation.

According to Demansys, the NYISO's Demand Side Ancillary Service 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 system.

The company notes its system responds to automated generator control signals from the grid operator, leveraging the same technology used to control traditional power plants. The grid operator, Demansys adds, sees these resources as just another supplier to the grid, and the company reports that it can predict the availability of the individual loads in the aggregate and help optimize how they are bid into the wholesale markets.
