Demansys brings 75 MW of reliability to New York power grid

Sponsored by

Demansys Energy began 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 has used its 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.

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, to provide reliability services to the grid operator. With deep experience aggregating different types of commercial and industrial loads, Demansys has been testing its technology in the Alternative Resource Regulation Pilot in New England since October, 2012.
