Estonia Has Created An "energy Shield Of The Future"

Europe's largest battery park will protect cities from blackouts.
Estonia has launched Europe's largest battery park for 100 MW, the experience of which will be key to protecting the Ukrainian energy system from blackouts and shelling.
According to Err.
The largest battery park in continental Europe was inaugurated in the Estonian city of Kiiza, which should strengthen the stability of the energy system and reduce fluctuations in electricity prices. The project was also the largest private investment in the history of the country's energy sector.
Evecon's battery park consists of 54 containers with lithium-ion batteries with a total capacity of 100 megawatts. The system is capable of storing electricity and returning it to the grid when needed, simultaneously providing electricity to about 90,000 households.
According to Evecon CEO Karl-Jonathan Kvell, the growing share of renewable energy creates new challenges for grid stability. After desynchronization with the Russian grid, Estonia has been independently responsible for the balance and frequency of the grid since last February, and high-capacity battery parks play a key role in this.
Estonian Minister of Energy and Environment Andres Sutt said such facilities help cut peak prices and make the cost of electricity more predictable. This is important both for consumers and investors who make decisions in the conditions of energy transformation.
The project in Kiiza was realized with the participation of French partners. The head of Corsica Sole, Mikael Kudize, emphasized that the investment is aimed at the development of carbon-free energy in Europe, and its payback is expected within ten years.
Evecon plans to open another similar battery park in Arukula by the end of the year. The total cost of the two projects is 170 million euros.
Why the Estonian experience is a "must have" for Ukraine
Ukraine today has the most extensive, but also the most wounded power grid in Europe. That's why such battery parks are our future:
Decentralization: Instead of one large thermal power plant that is easy to attack, dozens of such battery parks across the country create a "flexible" grid that cannot be knocked out in one fell swoop.
Fast start: Batteries react to a drop in frequency in milliseconds. It's ideal for maintaining the system after missile hits while power companies reconnect the lines.
Integration with RES: Ukraine plans to build many wind and solar plants. Without "PowerBanks" like Kijs, these plants could unbalance the grid.
