Bridging Research and Reality

At Wattnest, we're transforming cutting-edge research from Lawrence Berkeley National Laboratory into practical solutions for homeowners and utilities alike.

The Challenge We're Solving

The electricity grid faces increasing challenges in balancing supply and demand, especially with:

  • • Growing adoption of solar power causing midday overproduction
  • • Electrification of traditional gas appliances increasing peak demand
  • • Rising energy costs for consumers
  • • Increasing grid stability concerns

Through advanced algorithms developed and validated at Berkeley Lab, we can:

  • • Reduce your electricity costs by up to 29%
  • • Cut peak electricity usage by 70-80%
  • • Double the utilization of clean solar energy
  • • Maintain or improve your hot water availability

How It Works

Your water heater becomes a thermal battery, storing energy when electricity is cheap and clean, and avoiding usage when electricity is expensive and carbon-intensive.

1

Monitors real-time electricity prices

2

Predicts your hot water usage patterns

3

Automatically optimizes heating schedules

4

Communicates with utilities through standard protocols
