WELCOME TO ECS

What began as a simple two man operation several years ago, Energy Curtailment Specialists, Inc. (ECS) has evolved into the largest demand response provider in the United States, with more then 2,000 MW of load under management. Thousands of customers have joined forces to reduce 600 MW of power from the grid each and every time an emergency-level crisis occurs. This is enough electricity to power 600,000 homes.

The State of California has become more serious with the concept of demand response, designating it as one of the first elements necessary for a successful energy policy.  ECS, as the largest

provider, has been behind the push towards opening up these programs in California to independent companies called Aggregators. ECS is an aggregator approved to operate as such within the State of California. 

ECS is considered the leader in its field and respected by others in the industry.  Our customer-first approach has been the key to our growth over the past several years. We look forward to bringing true demand response to California and bringing significant revenues and energy savings to the doors of California businesses.  Over the past five years alone, ECS has paid more than $35 million to participants in its programs.
