Elisa Estonia deploys Elisa Industriq’s Gridle optimization to support grid balancing and strengthen network resilience

Elisa Estonia has deployed Elisa Industriq’s Gridle battery optimization solution across its mobile network to strengthen network resilience, while also enabling its base station batteries to contribute to balancing the Estonian electricity system operated by Elering. With the deployment, backup batteries at Elisa Estonia’s base stations are managed using Gridle’s AI-powered optimization solution.

Key benefits of the Gridle deployment 

• Resilience beyond regulatory requirements 

Intelligently controlled battery storage helps keep the mobile network operational during power disruptions, significantly exceeding minimum regulatory standards. 

• Lower electricity costs through intelligent battery optimization 

AI-driven charging and discharging optimise energy use across base station sites, significantly reducing electricity costs. 

• New revenue from electricity markets 

The solution enables participation in wholesale and balancing markets, allowing Elisa Estonia to monetize its battery assets. Combined with energy cost savings, this supports a fast return on existing battery investments. 

• Supporting renewable energy integration and sustainability 

By automatically charging batteries when renewable electricity is abundant and supporting grid balancing, the solution helps increase the use of renewable energy and contributes to a more stable and sustainable electricity system. 

Supporting Estonia’s energy transition 

The deployment follows Estonia’s synchronization with the Continental European electricity system, after exiting the Russian-led BRELL electricity system in February 2025. This transition enables new forms of flexible electricity use and allows distributed assets, such as batteries in telecom networks, to participate in supporting grid stability. 

By enabling more dynamic interaction with the national electricity system, Elisa Estonia’s base stations can respond to fluctuations in electricity demand and supply while maintaining reliable mobile connectivity. Through Gridle, the batteries participate in both upward and downward aFRR (automatic frequency restoration reserve), automatically charging or discharging in response to signals from Elering. 

“Intelligent energy management is an increasingly important part of ensuring reliable networks. This deployment strengthens our resilience and supports Estonia’s evolving energy system,” said Andrus Hiiepuu, CEO, Elisa Estonia. 

“Gridle was originally developed for Elisa’s own network, and the same network optimization and resilience capabilities are already in use in Finland. We are pleased to now deploy the solution in Estonia, where it can support both reliable mobile connectivity and the stability of the electricity system,” said Jukka Pekka Salmenkaita, Managing Director, Gridle, Elisa Industriq. 

Commercially available solution for energy optimization 

The Gridle solution is available internationally and has already been taken into use by several telecom operators outside Elisa, reflecting growing interest among operators in combining network resilience with more efficient energy use. 

In addition to telecom networks, Gridle optimizes grid-scale energy storage, commercial and industrial battery systems and residential batteries.
