Lumme Energia, Etelä-Savon Energia and Tieto’s groundbreaking energy solution lowers both emissions and the energy bill – first in Finland

04 April 2019

Tieto, Lumme Energia and Etelä-Savon Energia have together developed a smart energy solution, where the Lumme Energia head office functions as a virtual power plant. This is the first project of this scale utilising renewable energy sources in Finland. A successful pilot phase shows that the solution could be applied to public or commercial buildings and residential houses as well. Lumme Energia's energy solution enables using real estate in the effort of balancing Finland's electric grid frequency, steering power consumption towards more sustainable, zero-emission energy sources.

In Lumme Energia's solution, the building services technology of their head office, together with Etelä-Savon Energia's Foremica energy management system, solar panels, battery energy storage and electric vehicle charging, are connected to Tieto's cloud-based energy management platform, Tieto Distributed Energy Solution (DES). This system provides consumption flexibility needed to balance out the fluctuation of weather-dependent power production.

"The energy market has come to a turning point. Renewable energy production and the changing Nordic power market both cause disruption in the market. The effects of the Finnish 15-minute imbalance settlement period project and the weather-dependent fluctuation of power production need to be figured into the equation as well. At the same time, demand for power will grow significantly with the advancement of technology, such as the rapidly increasing numbers of electric cars and data centre capacity. To manage this complex system as a whole, we need dynamic, agile digital platforms that produce technical and economical benefits for all parties of the electricity market. Together with Tieto, we have created a development platform for digital energy services that allows us to prepare for the change to come while pioneering the digitalisation of the energy industry", says Miko Huomo, Lumme Energia's Director of New Business.

Smart platform combines power production, distribution and consumption

Tieto and Lumme Energia's solution enables smart, centralised management of small-scale power production, energy storages, electric vehicle charging and building services automation. With the digital platform, energy consumption can be optimised, resulting in decreased costs, and the same resources can be used as a virtual power plant. The virtual power plant helps us in our mission of increasing consumption flexibility in the Finnish energy system. The solution enables an increase in renewable energy sources such as solar and wind to replace production based on fossil fuels. When smart energy solutions gradually become more common, they create savings as the necessary consumption flexibility can be achieved cost-effectively with the help of virtual power plants.

"The solution allows us to optimise the total energy consumption and deliver smart, cost-effective energy services for buildings, micro production and electric vehicle charging. We can harness solar power systems, energy storages, electric heating/cooling, ventilation systems and electric car batteries to create value in the energy markets and decrease the carbon footprint of energy production. Our cooperation with Lumme Energia is a great example of a market-driven, sustainable solution. We are very happy with the cooperation and being able to promote environmentally more sustainable energy solutions in society", says Timo Karpola, Head of New Energy Services, Tieto. 

“Here at Etelä-Savon Energia, we are extremely happy that, together with Lumme Energia and Tieto, we were able to carry out this pilot and overcome the various technical challenges in integrating different equipment to build a whole new smart energy solution”, says Toni Hannula, Product Manager, Solar Energy at Etelä-Savon Energia. 

The implementation of Lumme Energia's smart energy solution has been reviewed with Fingrid, and is applicable for participation in the reserve market.
