Important results from the project

The project has been successful and reached the market with product and service. Real tests show cost savings for users according to forecast. More importantly, based on economic incentive, 100% of electricity purchases are easily moved to low-load times. Zavepower - Energy Optimizer fits the Swedish market perfectly in that the consumer can easily switch to hourly price contracts. But even those who have a fixed price subscription can, with the help of Energy Optimizer, for social and environmental reasons, participate and avoid electricity purchases at peak times.

Expected long term effects

Zavepower - Energy Optimizer is now sold to customers who already have hot tubs, and to hot tub manufacturers and their dealers. This means that customers have the opportunity to buy an energy-smart spa bath, or upgrade their current bath. The production cost of Energy Optimizer has already been pushed down through volume, this means that for only €299 users can avoid buying electricity for heating at peak times. This results in a traditional spa bath now becoming an energy-smart product that does not load with energy use when other social functions need electricity more.

Approach and implementation

From idea to finished service/product, the biggest challenge was to create the central software, as well as to result in a final product that is easy for the end customer to plug in - Plug & Play. In order to be close to developers and production, we chose to place all this in Sweden. Easy to meet and solve problems in a social environment where both the idea-creating problem exists, but also the solution´s infrastructure and pricing model regarding energy. This resulted in us being able to go to market within a year with a quality-assured product with very high reliability.
