The largest solar park in Southern Estonia, located in Raadi

In 2026, Estiko Energia opened the largest solar park in Southern Estonia. Located in Raadi, Tartu, the park covers 106 hectares and can supply green electricity to an average of half of Tartu’s households.

74 MWp total capacity

106 ha of solar park area

74 GWh expected electricity generation

2025 started production

110 kV network connection

69,000 tonnes less CO2 emissions in the atmosphere

H2 – part of the IPCEI hydrogen project

Solar parks across Estonia

Estiko Energia OÜ has constructed 14 solar parks with a total capacity of 64W across Estonia. The electricity generated by the solar parks is distributed to end-users, the power network and, via a direct line, to the companies of Estiko Group. Thanks to the solar parks, we have managed to reduce the CO2 emissions of Estonia by 71,000 tonnes, which is approximately equal to the amount of CO₂ emitted by Tallinn’s public transport over 5.3 years, or by a passenger jet flying around the world 125 times.

Future projects

Hydrogen

We see green hydrogen as an energy carrier of the future which can be used in places where there are no network connections or where the establishment of such connections is not economically viable. Green hydrogen could be used in local heat and power generation technologies to reduce emissions from wood-stove heating as well as in different means of transport that travel long distances daily and, in the case of which, it is not feasible to use battery power (e.g. city buses, refuse collection vehicles, street maintenance vehicles).

Pyrolysis

In the packaging manufacture of Estiko-Plastar, 120 tonnes of production residues are generated each year which, at the moment, constitute a problem for the company in terms of both additional waste and cost. We are exploring the possibility of using pyrolysis to recycle the waste and produce synthetic fuel from it, which would classify as green energy.

Storage

Volatile energy prices and the higher pricing of peak power call for local energy storage devices which would help balance surge pricing and avoid expensive electricity. In the case of an uninterrupted production process, the objective is to enhance the security of supply.

Balancing market

In the case of significant fluctuations in daily energy prices, it is smart to balance one’s energy consumption. However, we are exploring the opportunities for storing energy when electricity prices are lowest so we can resell it to the grid during a more expensive period.

Frequency control / maintenance

In 2025, Estonia will disconnect itself from the Russian electricity grid which has controlled our frequency thus far. From that moment, Estonia and other Baltic States have to be able to control their own frequency. A frequency control market will be launched, which we are currently preparing for. We want to contribute to the energy security of Estonia.

Virtual power plant

Electricity shortages and surpluses can be offset by changes in consumption. If a sufficient number of highly inert electricity consumers (e.g. cold stores and shopping centres) are connected, it is possible to change their electricity consumption without significantly changing their indoor climate. Such a group of flexible consumers constitutes a virtual power plant. Flexibility in power consumption will be of crucial importance in the future.
