Welcome to ECS

Energy Curtailment Specialists, Inc. (ECS) is the largest private demand response provider in North America, offering turnkey, administrative and a la carte demand response services. Winner of the Peak Load Management Alliance's "Outstanding Program Achievement Award" in demand response, a large part of ECS' success stems from having customer-friendly programs. ECS understands what it takes for a business to become involved and the preparation necessary to make energy reductions.

Founded in Buffalo, New York, in 2001, ECS had the goal of helping to ensure reliable electricity supply in New York State. Through hard work and dedication, and due to the real need for demand response, ECS has grown to an employee force of more than 220, and expanded into energy markets across North America, helping formulate demand response program models for utilities and system operators. ECS works with thousands of customers and manages more than 2,000 MW of demand response throughout North America, equivalent to the output of 3 large power plants.

Over the years, ECS has remained a private company, profitable each and every quarter, with a track record of paying customers. A streamlined management gives ECS the ability to make decisions and take action swiftly, and without third-party shareholders in the equation ECS' primary objective is to cater only to the needs of its customers.
