Real-Time Electricity Demand Reduction

Open Energi’s software turns energy-intensive equipment into flexible devices, reducing their electricity consumption when demand for electricity is higher than supply.

Open Energi works with large energy users to turn their energy-intensive everyday equipment – including fridges and furnaces – into smart devices that can adjust their electricity consumption in real time to help UK utility company, National Grid, manage electricity supply and demand. Open Energi’s Dynamic Demand platform responds to changes in grid frequency within two seconds and then unlocks small amounts of flexible energy demand and aggregates it to create a distributed storage network, intelligently increasing or decreasing consumption in real time, to help create a market that does not need polluting peak power plants to be turned on when electricity demand is highest.
Open Energi develops contracts for each customer, but typically covers the capital costs to install the technology. It then shares with customers revenues it receives from National Grid for helping to balance electricity supply and demand. As of February 2016, Open Energi had 41 contracted customers, twice as many as the year before.

Relevance of solution

Demand flexibility, storage, and interconnection are essential in helping to reach carbon emission reduction targets.1 By aggregating energy demand from flexible equipment, Open Energi provides no-build, flexible capacity which is cheaper and cleaner than most alternatives.

Triple Bottom Line


Dynamic Demand provides a direct alternative to fossil-fueled peaking power stations as a means of balancing electricity supply and demand, saving 2,276 metric tons of CO2 per MW per year.2 


Because the technology is governed by equipment control parameters, the equipment will only respond if it can do so without affecting performance or operational processes.


Creating a more flexible system could save UK consumers between $4.2 and $11.7 billion per year in 2030.3
