Our way saves cost and energy

Real-time data and alerts, delivery charge insight, and targeted integrations like heating and EV charging – this is our combined ecosystem for energy smartness. Saving energy should be easy, and not require concessions in comfort or cost.

Electricity – a complicated product

Electricity can be difficult to deal with for end-users, and new delivery charge structures made it even trickier. But that also makes for an opportunity; in offering consumers help, simplification and reassurance while navigating it all.

Right moves at the right moments

Our optimization prioritizes high-impact loads, which makes it more likely to generate savings, and flexible in making split-second decisions to avoid costly peaks. Though we only optimize if we know we can maintain safety and comfort.

Satisfied customers stay with you

End-users have many energy needs, but the vast majority wishes to save money without getting too involved. Our systems are built to function with little input, and wherever needed, we take great care in giving the right recommendations.
