100 electric water heaters can consume about a megawatt hour of clean energy...every single day.

About 40% of U.S. homes have electric resistance water heaters. The average high efficiency electric water heater consumes about 12 kWh of electricity per day. If you control water heaters to only heat when there is excess renewables on the grid, they become a viable alternative and complementary solution to battery-based grid storage solutions.

Our solution can preheat hot water to consume excess renewables while still providing residential and business participants with hot water when needed.

How our solution works

We work with utilities and microgrid operators to identify suitable tanks to replace with high efficiency electric water heaters. In some cases, we can retrofit existing water heaters.

We install your selected heaters with control systems and leverage existing communications infrastructure or install a communications infrastructure. We can also tie into custom communication systems including smart grid networks.

We work with you to identify how your fleet of water heaters should consume energy and then setup automated controls. We ensure participant comfort by only aggregating tanks that need preheating and temporarily exclude colder tanks.

We can integrate into energy management systems or enable custom web based administration applications so you can control your dispatchable fleet as needed. We also provide real time dashboards to monitor your fleet's performance and assist with participant support.

Additional benefits

Low cost gird services

Utilities can use fleets of grid-enabled water heaters for load shifting, demand response, arbitrage, ancillary services, or to respond to unexpected grid-stabilization events. See this white paper for more info.

Ready to scale

We have more than 500 systems under contract with multiple customers. We can integrate our solution quickly into residential and small business locations including participant recruiting.

Reach underserved communities

Our solution can easily be deployed in underserved communities including rental units, apartment buildings, and small businesses to help enable equitable participation across clean energy programs.
