What you can do with Watts


Get a complete overview

Watts makes it clear and easy to follow your electricity consumption, and at any time you can see how much you have used.
The unique thing about Watts is that it looks into the future and predicts the expected consumption specifically for your household. It gives you the opportunity to act, before your electricity consumption becomes greater than it should be.


Energy used and daily measurements

If your home has a smart meter that automatically sends your electricity consumption, then the Watts app can automatically register your electricity consumption hour by hour. In this way, you can get a precise overview of your daily electricity consumption as well as see which times of the day you are using the most electricity.
In addition, you can easily see what your basic consumption is, i.e. how much power you are using when nothing is on, apart from the essentials like the fridge, freezer and appliances on standby.


Green power zones

Keep an eye on when the power is greenest in Denmark and plan your consumption according to that. For example, you can wait with washing clothes until you can see that the energy is mainly coming from wind turbines. In that way, you can contribute to greener consumption.


Easy to follow the delivery of electricity to the grid

Watts gives you a simple overview of how much electricity you have delivered to the grid in the current period. In addition, you can also find the net difference – in other words, the difference between the buying and selling of electricity.

About Watts

Who's behind Watts?

Watts went live in the autumn of 2016 with the goal of giving you as an simple and comprehensive overview of your energy consumption. Watts shows your expected electricity consumption so that you can react before your electricity use gets out of control. The energy company SEAS-NVE is behind the Watts. SEAS-NVE is Denmark’s largest customer-owned energy company.


Frequently asked questions

The unique thing about the new Watts app from SEAS-NVE is that it looks into the future and predicts the expected electricity consumption specifically for your household. As soon as you open the app, the bubble’s colour shows you whether you are over, slightly over or under budget for the quarter. This gives you the opportunity to react before your electricity consumption gets bigger than it should be.

The bubble’s colour tells you whether you are on course to use more or less electricity than budgeted for this quarter. Red/orange/green means over/slightly over/under budget for the quarter.

Watts differentiates between variable consumption and basic consumption so that you know where to look if you want to save energy. There is a coloured dot (green/orange/red) next to “Variable use” and “Basic consumption” so that you can easily see where you need to investigate.

If there is a red dot, it indicates that it is possible to save energy, since your electricity consumption is above the expected consumption; orange shows that your consumption is slightly over your expected consumption; and green shows that your consumption is under the expected amount.

Basic consumption refers to your home’s lower limit, also known as “always-on” use, such as consumption for the fridge-freezer, electric heating, heating pump, water pump and devices on standby. This will typically be devices that are turned on a minimum of once per hour. Basic consumption is calculated by looking at the home’s lowest, hourly consumption a week ago. When you look at a specific day, then the basic consumption is shown for the chosen day.

Variable consumption is the electricity consumption that is above your basic consumption. When you look at a specific day, then your variable consumption will also be shown for the chosen day.

You can see how much electricity you have sold to the grid in the applicable month in kWh. You can also see the net difference in kWh. The net difference is the calculation that shows how much you have sold to the grid, minus what you have used from the grid. SEAS-NVE does not know how much your system has produced or your actual consumption, because consumption and production are cancelled out by each other before they “reach” the meter. ATTENTION! Watts does not take into account your payment/billing agreement. This means that Watts does not necessarily show what you will be paid or billed.

Smartphones can download Watts from the App Store or Google Play. For Apple devices, Watts requires Ios 9.0 or newer. For Android devices, the operating system must be version 4.0.3 or newer. If you want to install Watts on an iPad, please be aware that we cannot guarantee that it will function as expected, since Watts is only developed for smartphones.

What users say about the app

  • – I like that the app also looks into the future. It gives me the possibility to react before my electricity consumption gets bigger than it should be.

    Henrik, 41 years, Maribo
  • – I have solar panels and watch my sales to the grid. Before, I had to go up in the loft and write the numbers down, but now I can just open the app. I can also see if the panels have produced more or less electricity than I’ve used from the grid – that’s clever!

    Henning, 64 years, Kalundborg
  • – We have a second home in Odsherred and use the app to keep an eye on electricity consumption – especially when we rent the house out. Then we can check that the tenant hasn’t forgotten to turn something off. We can also see what it costs to keep the house free of frost in the winter. I think it’s nice to have a good overview.

    Kirsten, 56 years, Rødovre
  • – I’m all for sustainability, so I’ve started looking at the app before I wash clothes. When I can, I use the washing machine at times when the electricity consumption is the most climate friendly.

    Sanne, 32 years, Næstved
