Are you the owner or manager of a multi-family property? If so, we want to connect with you. Mosaic Power’s Water Heater Efficiency Network (WHEN) connects the electric water heaters in your properties through a secure cellular connection with our office in Frederick, Maryland.
Grid Operators
Mosaic offers a range of services to the grid management community—from managing demand by-the-minute to smooth frequency, to reducing demand by our network during peak hours. Our smart management of water heater demand during peak hours reduces the use of expensive peaking generators.
Climate Impact
WHEN water heaters unite, everyone benefits, including our environment. We are leading the way in connecting affordable housing to a smarter grid, and a smarter grid means cleaner air, renewable energy, and a brighter future for us all.
