tado x aWATTar

Munich, 11 January 2022, tado°, the European leader in intelligent home climate management, has today announced its acquisition of aWATTar GmbH, a technology company that provides power loadshifting through Time-of-Use energy tariffs. This combination of tado° and aWATTar technologies enables the growth of renewables in the European energy market, for a more sustainable future.

Significant Savings from Price Volatility

79% of household energy consumption comes from heating and hot water. tado° plans to utilize the energy transition towards the electrification of heating. Since intermittent renewable energy sources (Solar PV and Wind) are the cornerstone of the transition, electricity prices are becoming increasingly volatile. tado°’s technology can intelligently shift the heating of homes to lower priced times in a volatile energy market. Combining this with aWATTar’s Time-of-Use energy tariffs will provide customers a significant opportunity to save on their energy costs whilst retaining the comfort level they are used to.

From Heating and Cooling, to Electric Vehicles and Solar PV

tado°’s market leading heating and cooling platform is compatible with 18,000 heating systems from over 900 manufacturers. 10 years of user insights and algorithmic development are at the heart of this technology.

aWATTar has previously developed integrations with OEM’s from the electric vehicle charging and the photovoltaics industry. The acquisition makes tado° an important technology platform, allowing customers to automatically shift their energy consumption across a range of intelligently managed applications specifically towards times of lower prices.

Renewable Energy for Europe

The current energy system can only hold a limited amount of renewables in order to guarantee security of supply. The combination of tado° and aWATTar technologies will enable customers to become a proactive part in a more flexible energy system, allowing for the growth of renewable energy share across Europe. 

tado°’s Co-Founder and CPO Christian Deilmann says “The team at aWATTar have built a strong technology backbone. Time-of-Use energy tariffs through algorithmic trading and billing automation benefits not only heating but also for electric vehicle charging and photovoltaic applications. Their technologies offer great value to customers and we look forward to working with them to deliver a better future of energy in Europe: energy usage completely in sync with nature, when the wind blows or sun shines.”

aWATTar CEO Simon Schmitz says “We’ve been huge fans of tado° for a long time. Both companies share the strong vision of a smart and decentralised energy world. We are very pleased to be able to take aWATTar to the next level in partnership with tado°. Seeing how tado°’s smart thermostats can shift energy demand across our time-of-use tariffs has been incredible. We can’t wait to further develop these technologies together for our customers.”

tado° is already partnering with a variety of OEMs, and 12 of the top 20 utility companies in Europe, such as E.ON, Engie, Octopus, Ovo, Total, Shell, Naturgy, Vattenfall, EDF, SSE and Eni. The new offerings will also be available to all these existing and new tado° partnerships. 

As part of the transition to becoming the most impactful energy efficiency and management platform, tado° plans to acquire other energy-sector companies that can drive consolidation into this fast growing market. aWATTar co-founders Simon Schmitz (CEO) and Peter Netbal (CTO) will keep driving the aWATTar strategy as Managing Directors of aWATTar GmbH and as new shareholders of tado° GmbH.
