Mosaic offers a range of services to the grid management community—from managing demand by-the-minute to smooth frequency, to reducing demand during peak hours.
Mosaic Power’s Water Heater Efficiency Network (WHEN) provides community energy storage services to the electric grid. Our state-of-the-art system optimizes the timing of energy usage among thousands of electric water heaters, synchronizing electricity demand by water heaters with the needs of the electric grid.
WHEN is one of the few energy technologies that is both cost-effective for the grid and best suited to affordable housing. A WHEN connection makes each property more sustainable while making the electric grid cleaner and more reliable. In addition, our smart management of water heater demand during peak hours reduces the need for expensive peaking generators.
WHEN takes a “Bring Your Own Water Heater” approach to community energy storage services. We do not require new and costly water heater purchases. Instead, our equipment utilizes the thermal energy storage potential of existing water heaters.
Mosaic Power’s WHEN is currently operating more than 13,000 water heaters within PJM’s Frequency Regulation Market. We have been operating within the PJM market since 2013, making the grid cleaner and more reliable—and there is great opportunity for ongoing growth.
