New York, NY – January 18, 2018 – EnergyHub, the leading provider of connected device and distributed energy resource (DER) solutions for utilities, and Rheem®, a leading global manufacturer of heating, cooling and water heating equipment, announced today they have integrated Rheem intelligent water heaters with the EnergyHub Mercury DERMS platform.

EnergyHub’s utility clients can now aggregate, monitor, dispatch, and optimize fleets of Rheem intelligent water heaters to deliver grid services. The partnership is the latest expansion of EnergyHub’s industry-leading DER ecosystem, which includes the leading manufacturers of connected thermostats, electric vehicle charging equipment, grid-interactive water heaters, energy storage systems, and smart inverters.


“This integration gives EnergyHub’s customers the ability to deliver intelligent grid-service capabilities with devices from another leading DER manufacturer,” said Seth Frader-Thompson, President and Co-founder of EnergyHub. “We’re excited to provide our utility clients access to Rheem’s products as DERs continue to play a more central role in day-to-day grid operations.”

Rheem and EnergyHub are already deploying their integrated solution with a major utility in the northeast. The program will broaden the utility’s demand response portfolio while creating the potential for the utility to use water heaters for other grid services.

“Partnering with EnergyHub was an easy decision for us,” said Nitish Singh, Vice President of Product Management and Marketing at Rheem. “With our new line of intelligent products, Rheem empowers families to improve their monthly bill by signing on to their utility demand response programs. EnergyHub’s Mercury DERMS is a great demand response platform that offers many of the largest utilities in the United States efficient access to Rheem’s intelligent water heaters.”

EnergyHub’s Mercury DERMS is used by more than 30 utilities across the United States to manage demand response, energy efficiency, and DER programs. Combining sophisticated analytics with the largest ecosystem of connected device and DER partners in the industry, EnergyHub’s Mercury DERMS is the industry-leading platform for helping utilities manage both customer- and utility-installed DERs.
