Amazon-backed start-up tado uses smart thermostats to cut heating emissions
Company profile
- Tado makes that connect heating and air conditioning systems to the internet. Its smartphone app incorporates weather forecasts and other data to set temperatures efficiently and control home systems remotely.
- Its thermostats are already installed in several hundred thousand European households.
- The company was founded in Munich in 2011 and has grown to almost 200 employees.
- In its in October 2018, tado raised 50 million dollars from Amazon, the German utility E.ON, the European Investment Bank, Total Energy Ventures, Energy Innovation Capital and Inven Capital. That brings its total investor funding to 102 million dollars.
- The tado app can be controlled with Amazon鈥檚 Alexa and other virtual assistants.
Why tado matters
- Increasing heating efficiency is central to reaching Germany鈥檚 climate targets, but progress has been slow. Tado shows the potential for new business ideas to help lower emissions in this sector.
- Tado鈥檚 business plan illustrates renewable electricity鈥檚 increasing role in heating and air conditioning 鈥� a process often referred to as 鈥渟ector coupling鈥� or 鈥渆lectrification鈥�. This offers new potential for 鈥渄emand-side management,鈥� or the process of adjusting energy consumption to match an intermittent renewable supply.
- The company鈥檚 plans also reflect the growth of services aimed directly at end power consumers. As energy technology enters the home, it opens up whole new markets. By managing individual households鈥� energy use, companies can then offer additional services 鈥� in tado鈥檚 case, remote appliance maintenance or grid balancing.
What tado says
威力彩玩法 spoke with tado's co-founder Christian Deilmann, who is in charge of product strategy and business development.
威力彩玩法: How would you evaluate the current progress of the energy transition here in Germany, especially in heating?
Deilmann: We鈥檙e basically on the right track, but we鈥檙e much too slow, and heating still doesn鈥檛 get the attention it should. Heating and cooling in our buildings and industry accounts for half of the EU鈥檚 energy consumption. In EU households, heating and hot water alone account for 79 percent of total energy use. In Germany, heating accounts for approximately 55 percent of energy consumption. These figures illustrate what a huge role heating must play in the energy transition. On a global scale, around 30 percent of all energy is used for heating and air-conditioning 鈥� that鈥檚 more than the entire transport sector.
The mere fact that the sector is responsible for such a large share of emissions should make it a top priority, both with respect to energy efficiency, but also with regard to the transition to a renewable energy system.
Where is the future of heating headed?
In general, it鈥檚 extremely important to manage energy consumption intelligently 鈥� regardless of the energy source 鈥� in order to reduce overall consumption. I believe that is the first lever we have to use, because it鈥檚 also relatively simple. Tado offers a small device that you can connect to any type of heating system. By adding other data to heating management 鈥� such as weather forecasts, data on open windows, data on which rooms are being used, and so on 鈥� and combining them with a learning system that gets to know a building鈥檚 relevant characteristics and improves over time, we can save up to 31 percent of heating costs. That鈥檚 a very important point.
As regards energy sources, we believe there is no alternative but to decarbonise the system in the longer term, which means we will heat and cool using renewable electricity primarily from wind and solar power. This process is often called 鈥榮ector coupling,鈥� meaning we connect the power sector to the heating and transport sectors and run the entire economy on renewable electricity. This will enable us to use intermittent renewable power much more effectively. Heating in particular offers a huge potential to add flexibility to the grid, for example by using heat storage and the thermal inertia of buildings as a buffer. Electricity-based heating systems, for example heat pumps, not only work much more efficiently, but can also be used to stabilise the grid.
Turning to your business: Do you consider yourself a software or hardware company?
We employ around 80 product developers. Of these, only three work in hardware development, and the rest in software development. To develop a solution like tado, you have to invest primarily in the software. The hardware is much less laborious. Seen from this perspective, we really are a software company, even if the product we鈥檙e selling is a combination between hardware and software.
Could you tell us some details on your business development? Are you profitable?
We鈥檙e still in the investment phase. Our total financing adds up to more than 100 million dollars. We concluded a financing round in the autumn of 2018 totalling 50 million dollars, which we鈥檙e currently investing. This is why we鈥檙e not yet profitable. We are currently serving several hundred thousand households, which we manage to increase comfort, efficiency and convenience.
It鈥檚 rather unusual for a German start-up to have . What did the collaboration mean for you?
Amazon has large ambitions in this sector and we cooperate closely. The partnership has already yielded large benefits, both in the number of households we can reach, and also regarding the possibilities to improve our product.
What are the next goals for your company?
Adding connectivity to heating and air conditioning offers three different value pools. First, what we do today: lowering energy costs and increasing comfort for end customers, which is a control issue. Second, remote maintenance of appliances, which makes repairs and maintenance much more efficient. If you already know why a heating or cooling system is broken, you only have to visit the customer once, because you know which spare parts to bring along. The third value pool is the aggregated sum of all our households using electricity for heating or cooling, because they can be integrated into the electricity grid and programmed to use electricity when it is readily available and cheap 鈥� when the wind blows or the sun shines. This offers the option to adapt energy demand to production, without having to make concessions regarding comfort.
Currently, we鈥檙e strongly involved in the first value pool. By increasing efficiency and comfort, we access households. That is the basis for entering the other value pools step by step, which we鈥檝e already begun. We鈥檙e working on reaching a critical mass of users, which will allow us to take part in grid management.
We鈥檙e working on reaching a critical mass of users, which will allow us to take part in grid management.
But it鈥檚 important to realise that the heating sector moves very slowly when compared to other sectors 鈥� just think of the internet. You need a lot of staying power in this business. We鈥檝e grown to around 200 employees and have reached a respectable size by being installed in several hundred thousand households. But in total, there are 200 million households in Europe. It will take some time before they鈥檙e all connected.
What are the main regulatory obstacles slowing your business expansion?
Flexible energy prices are a very good development, meaning the electricity price depends on how much energy is currently available in the grid, and fluctuates accordingly: it鈥檚 cheap when there is plentiful renewable energy, and gets expensive when supply is short. This concept has progressed very far in Finland and Sweden. In the UK, there are also four utilities that offer flexible prices, for example .
Intelligent control systems like tado鈥檚 are a perfect complement to flexible pricing contracts. We鈥檙e active in all European countries, and these contracts make it much easier for us, because we don鈥檛 need all the cumbersome certification process to become an official provider of balancing power in every country. Simply integrating balancing power into the energy pricing system is the simplest solution for us and the customers, because everyone just needs the appropriate technology to use less power when it is expensive, and more at times when it is cheap.
Power prices are also an important aspect of this transition to renewable heating. The cheaper renewable power becomes, the quicker decarbonisation will progress.
Who are your main competitors?
On a global scale, is our most important competitor. In Europe, we鈥檙e very close 鈥� I would guess we serve a similar number of households, which is due to the fact that Nest is only active in some European countries, where it is bigger than we are.
But there are also strong competitors on a regional level. For example, which is also installed in several hundred thousand households, but only available in the UK. In the Netherlands, the utility Eneco has also equipped several hundred thousand households with smart thermostats.
In terms of volume, those three are our most important competitors in Europe.
How important is Germany for your business?聽聽聽聽聽聽
Germany accounts for around a quarter of our total sales, and other European countries account for most of the rest. This is why Germany remains our most important market, with the UK as a close second. Tado was set up from day one as a European company, which is why we鈥檙e relatively diversified.
What鈥檚 your opinion on the recent announcement that Shell is taking over German battery pioneer Sonnen and possibly also green energy provider Lichtblick? Do you see a trend here?
Oil majors in particular are not yet as embattled as many old utilities. They were able to earn a lot of money over many decades, and they have realised that the world is decarbonising and moving beyond oil. Both Shell and Total are currently snapping up firms on a weekly basis, in particular new brands in the classic energy sector that sell electricity or gas to end customers.
We noted earlier that transportation is also being increasingly electrified. Given this backdrop, it would be grossly negligent for these companies to say: 鈥榃e don鈥檛 care 鈥� we just pump oil out of the ground and that鈥檚 it.鈥� They have accumulated the necessary capital over the years to invest in decarbonisation themselves. There is no doubt whatsoever that they are very serious about this 鈥� this is definitely not greenwashing. There are simply too many reasons to favour a different approach now. One obvious example is energy efficiency. A conventional combustion engine has an efficiency factor of about 25 percent, compared to an electric motor with 97 percent 鈥� which means you lose much less energy. The same is true for heat pumps, which are four or five times as efficient as a conventional gas heating system.
In addition, I believe we鈥檙e also seeing a profound change in society. An increasing number of people are no longer prepared to be poisoned every time they walk in a city. There is an increasing resistance against the health effects of using conventional fossil fuels. Third, it鈥檚 simply fun to drive an electric car.
I believe those three factors 鈥� efficiency, health and the fun factor 鈥� are combining to drive the transition, both in heating and in transport.
How would you evaluate the general environment for energy start-ups in Germany?
There are many aspects to this question, but let me just focus on one example. About a year after tado got started, Nest appeared. And to be honest, we were quite impressed by their initial growth. The US is simply a huge market, with one language and one culture. It offers a similar number of households as Europe, but we鈥檙e split up into 28 countries, with many different languages, cultures, regulations, borders and tax systems, which all slow you down. Being in the US makes it much easier to scale up operations.
