Elering Tests Estonia's Energy System Readiness for Crisis
Estonian system operator Elering conducted technical tests on July 15 to verify the energy system's readiness to operate under partial isolation and its ability to restore power after a major blackout.
On July 15, Estonia's electricity system operator Elering carried out technical tests to assess the energy system's ability to function when part of the grid is temporarily isolated from the rest. During the tests, specialists examined the operation of equipment, control systems, and working procedures under more complex conditions than usual. The aim was to ensure that the solutions needed to restore power after a large-scale outage would work effectively in a crisis.
Märt Allika, head of Elering's power system control center, emphasized that system reliability cannot be ensured solely through plans and models. It is important to test in practice how the system behaves in a difficult situation and how it can be restarted if necessary. The company noted that the tests were conducted in controlled conditions and posed no risk of power supply interruptions. According to Elering, consumers did not feel any impact from the testing.
Currently, Estonia has a limited number of options for restoring the energy system after a complete shutdown. The tests allowed one of the existing options to be checked. At the same time, Elering is developing additional solutions that would enable the system to be started from multiple points simultaneously in case of a major accident. The company believes that the more such options exist, the greater the resilience of the country's power supply in emergencies. Elering stated that regular reliability testing and the development of restoration capabilities are part of ensuring Estonia's energy and crisis security.
