Diotech OÜ and Solar Wheel OÜ joint tender won the international procurement of large-scale storage device organized by Eesti Energia

We are proud to announce that the joint tender of Diotech OÜ and Solar Wheel OÜ, with LG Energy Solution supplying the battery technology won the international procurement of large-scale storage device organized by Estonian national energy company. The capacity of the new storage device will be 26.5 megawatts and 53.1 megawatt hours. The storage facility will be operational by the beginning of 2025, at the same time as the Baltic countries are disconnected from the Russian electricity grid. This is a pilot project to ensure the solution is suitable both in Estonia and the company’s other retail markets.

According to Diotech OÜ management board member Mart Moora, the company’s mission is to accelerate society’s transition to carbon-neutral electricity production and consumption.

“To serve our mission, we have deliberately developed over several years the ability to design and build battery technologies, as they are key in making renewable energy production controllable,” said Moora.

“We are honored to bring LG Energy Solution’s state-of-the-art storage systems to the Estonian market and to cooperate with Eesti Energia in this pilot project. We will do our best to ensure that the system we are building performs as expected and that the pilot project meets everyone’s expectations.”

The capacity of the new system corresponds to 2 hours of consumption for approximately 75, 000 households. A large-scale storage device enables Eesti Energia to participate in power exchange as well as other electricity markets to ensure the security of electricity supply. It would also fully cover the FCR frequency reserve need in the Baltics.
