Virtual Power Plant

Distributed Grid-Interactive Solar Photovoltaic Smart Heaters + Storage paired with AI and IoT to deliver low cost VPPs


Our Re:Heat photovoltaic charge controller can retrofit to existing water heaters and through IoT, AI and the power of self-learning algorithms, will transform existing passive water heaters into Grid-Interactive energy storage assets.

This will allow for peak load reduction through energy shifting, peak shaving and energy arbitrage that can aid the utility company and reduce energy cost for the electricity user. 

Who Can Benefit?


Take control of decentralised water heaters and repurpose them as  energy storage assets. Implement load shifting or peak shaving when generation is constrained or arbitrage in response to market conditions.  


Reduce heating costs with the integration of Solar Photovoltaics and benefit from lower cost generation during the day with inherent energy storage for deployment at night or when needed. 


Manage your fleet of hot water assets remotely and reduce the cost of serving hot water to your customers while reducing your carbon footprint. Can be extended to cooking and space heating. 

Benefits of Water Heaters as Virtual Power Plants

Grid Stabilization:

Distributed water heaters, when connected to a network, can act as dynamic energy storage units. During periods of peak electricity demand, these heaters can temporarily reduce their power consumption, thereby relieving strain on the grid and helping to prevent brownouts or blackouts

Demand Response Optimization:

By intelligently managing the heating cycles of distributed water heaters, energy providers can participate in demand response programs more effectively. These programs incentivize consumers to adjust their energy usage during peak hours, reducing the overall strain on the grid and ensuring stable energy distribution.

Carbon Footprint Reduction:

Traditional power plants often rely on fossil fuels, contributing to greenhouse gas emissions. By harnessing the potential of distributed water heaters as virtual power plants, the energy sector can decrease its reliance on non-renewable sources, thus contributing to a significant reduction in carbon emissions.

Renewable Energy Integration:

As the global shift towards renewable energy sources continues, the intermittency of renewables like solar and wind poses a challenge. Distributed water heaters can absorb excess energy generated during sunny or windy periods, converting it into heat for later use. This significantly improves the efficiency of renewable energy integration into the grid.
