Estonia's Elisa Deploys Gridle Solution to Support Grid Balance and Network Resilience

en.Wedoany.com Reported - Estonian telecommunications operator Elisa Eesti AS has deployed the Gridle intelligent energy optimization solution at its mobile network base stations, utilizing AI-driven battery energy storage systems to enhance network resilience and reduce electricity costs.

The solution ensures mobile networks remain operational during power outages through intelligent control of battery storage, with resilience performance exceeding minimum regulatory standards. Meanwhile, AI algorithms optimize charging and discharging strategies at base station sites, significantly reducing electricity costs. Additionally, the solution allows Elisa Eesti to monetize its battery assets by participating in wholesale and balancing markets. Combined with energy cost savings, this enables a rapid return on existing battery investments. This mechanism also automatically charges batteries when renewable energy supply is abundant and supports grid balancing, thereby increasing the share of renewable energy usage and promoting a more stable and sustainable power system.

This deployment follows Estonia's exit from the Russia-dominated BRELL power system in February 2025 and its synchronization with the continental European power system. This transition enables distributed assets, such as batteries in telecommunications networks, to participate in grid stability support. Through Gridle, batteries at base stations can automatically charge or discharge based on signals from Elering, the national transmission system operator, participating in both upward and downward aFRR (automatic Frequency Restoration Reserve) markets.

Andrus Hiiepuu, CEO of Elisa Eesti, stated that intelligent energy management is a crucial component of ensuring a reliable network, and this deployment enhances both network resilience and support for Estonia's evolving energy system. Jukka-Pekka Salmenkaita, Managing Director of Gridle (Elisa Industriq), noted that the solution was initially developed for Elisa's own network, has been deployed in Finland, and is now being rolled out in Estonia to simultaneously support reliable mobile connectivity and power system stability.

The Gridle solution is currently commercially available in international markets and has been adopted by multiple telecommunications operators beyond Elisa. In addition to telecom networks, the solution is also suitable for optimizing grid-scale energy storage, commercial and industrial battery systems, and residential battery systems.
