Finland's telecom operators, such as Elisa and DNA Tower, are implementing Distributed Energy Storage (DES) to optimize electricity usage across their networks. DES leverages backup batteries at base stations to store surplus energy, enabling operators to shift loads, reduce peak electricity costs, and participate in energy markets. By aggregating these batteries into a virtual power plant (VPP), operators can balance the grid, integrate renewable energy, and potentially halve electricity costs . Elisa has already rolled out 150MWh of batteries and plans to expand to 2000 base stations, replacing lead-acid batteries with lithium-ion cells for higher efficiency and longevity .
AI algorithms are used to predict energy demand, optimize battery charging, and manage load distribution across the network. This approach allows telecom operators to purchase electricity during low-cost periods and store it for later use, while also providing grid services such as frequency regulation. AI-enabled DES systems enhance both economic and environmental performance, supporting Finland's goal of carbon-neutral telecom networks by 2030 .
Telecom networks in Finland face unique Arctic challenges, including extreme cold, reindeer migrations, and long periods of sunlight or darkness. Thermal-managed lithium batteries have been deployed to maintain high reliability (99.99% uptime) and reduce diesel generator usage by up to 73%, significantly lowering carbon emissions and operational costs . Proper thermal management ensures 7–10 years of battery life and a 3–5 year ROI for energy storage projects .
Research from Finnish universities and tech companies is exploring wireless electricity transmission for small and medium applications. Techniques using ultrasonic waves, electromagnetic fields, and radio frequency systems can power sensors, trackers, and other low-power devices without physical wiring. While not yet scalable for full base stations, these innovations could reduce reliance on traditional power lines and improve energy efficiency in the long term .
By combining DES, AI management, and advanced batteries, Finnish telecom networks can smooth out the variability of renewable energy sources, such as wind and solar. This integration allows operators to store excess renewable energy and use it when needed, reducing dependence on fossil fuels and supporting Finland's energy transition .
