The Illinois Power Agency has selected Voltus to supply Ameren Illinois with demand response capacity.
Voltus will help Ameren Illinois to achieve 653MW of demand response capacity to ensure grid reliability during the 2019/2020 operational year.
The deal brings the solution provider's portfolio of managed demand response capacity above 1,000MW and the only demand response provider to win a contract in the IPA all-source procurement process, which began in 2007.
Gregg Dixon, CEO of Voltus, said: "...it is the largest demand response public procurement award in the history of the demand response industry.
"And the MWs that Voltus is delivering are zero-emission credit-quality resources that don't need subsidies to provide safe, reliable, affordable and clean energy to Illinois electricity customers."
Alex Laskey, founder and former president of Opower, added: "...utilities across North America look to replace aging infrastructure through a combination of traditional generation, renewables and non-wire alternatives.
Matthew Plante, president of Voltus, reiterated: "The Illinois Commerce Commission, the IPA and Ameren Illinois deserve credit for embracing demand response as a solution to the capacity price shocks that MISO experienced in 2015 and 2016."
