Why the need for energy forecasting service?
The energy sector is undergoing a profound shift towards renewables and carbon neutral production of electricity. Simultaneously, the reliability requirements for power systems are becoming stricter reliability requirements for energy supply and the grid – the backbones of an effective energy market.
The shift also adds to the complexity of the operational environment and decreases the accuracy of energy forecasts. The volatility of market prices increases in response to changing weather conditions and their impact on energy demand.
At the same time, we now have more data available than ever. With the right energy forecasting service, you can leverage the market and grid data to create accurate forecasts. You can use the forecasts to optimise the transition towards renewables and ensure reliable energy availability in any situation.
In Finland, a 1% error in wind power forecasting costs roughly €300,000/year in imbalance settlements
VTT EnergyTeller uses AI to enable better energy forecasts
VTT EnergyTeller is an AI-powered solution that combines physics-based models and expert knowledge. It is an energy forecasting software designed to help optimise the production, distribution and consumption of electricity.
The solution can be used to benchmark your existing energy and load forecasts against state-of-the-art methods and the latest research. Just as importantly, the software works as a rapid forecasting solution for getting on top of your unsolved forecasting challenges.

Cost-savings and optimisation for electricity generators
More comprehensive models of the behaviour of the energy market enables producers to
- Predict energy prices according to historical data and weather forecasts
- Optimize your bidding strategy
- identify the best energy markets for your own generation profile
Among others, VTT EnergyTeller provides accurate forecasts of the weather and temperature, available generation capacity and the capacity need for battery-electricity storage systems. It can also be used to optimise the operations of combined heat and power (CHP) plants through storage and sector coupling.
More efficient and reliable electricity distribution
Combining data-based and physical models through hybrid modelling enables the optimisation of different energy applications, such as reactive power compensation and grid congestion issues.
Forecasting consumer behaviour and changes in power profiles throughout the day enables the effective compensation of reactive power.
VTT EnergyTeller can also help to identify potential grid congestion issues by spotting energy demand increases in specific areas. Power flow can be optimised when demand is high in specific areas.
Accurately predict the tomorrow’s energy demand
VTT EnergyTeller helps you optimise the use of your energy resources.
You can for example predict future demand in large buildings, industrial applications and energy communities to make full use of their flexible energy resources:
- Bid your flexibility in the energy markets
- Enable demand-response and optimise your demand according to forecasted prices.
