Uninterruptible power supply for power distribution in Estonia

During the transition, Estonia, Latvia, and Lithuania will manage electricity supply internally, relying on domestic power generation and energy reserves. The Tallinn University of Technology describes the process as similar to a house temporarily disconnecting from the main grid and operating on solar panels and batteries.

Estonia has gas turbines, oil shale power plants, and access to Latvia's hydroelectric power to balance energy needs. Additionally, the country can exchange electricity with Finland via undersea cables, though the two systems operate on different frequencies.

“The worst-case scenario would involve power outages lasting up to 72 hours. However, our priority is to prevent this.” Transmission system operator Elering has stated that the likelihood of large-scale blackouts is extremely low.

Despite concerns about potential disruptions, officials stress that Estonia is well-prepared, with Prime Minister Kristen Michal stating that while power cuts are unlikely, contingency plans are in place to manage any issues that may arise.
