Renewable energy is replacing fossil fuels at an ever faster pace. This is a great chance to transform our energy system into a sustainable one. At the same time this transformation poses great challenges for our electrical grid. Energy supply has to match demand in every second, which makes operating a power system that mainly runs on renewable energy from the sun and wind challenging.

One approach to balance demand and supply is Demand Side Flexibility where energy consumers adapt their consumption based on the amount of energy available. In a free market the shortage or excess of energy is reflected in the price. With the advancing rollout of smart meters in Europe, variable tariffs are emerging which reward the end costumer for using energy in times of the day where there is an excess and save energy in times where there is a shortage in renewable energy supply.

End customers are free to choose an energy supplier and a tariff of their choice. Based on their location they are assigned to a grid operator and may be able to choose their grid tariff too. Instead of having to implement each tariff in the smart device or ask the end consumer to do so, tounify offers a simple way to setup the tariff and retrieve day ahead prices daily.
