Vaisala’s Xweather Optimize Helps District Heating Providers Save €300,000 Annually by Improving Weather Forecast Accuracy

(IN BRIEF) Vaisala’s Xweather Optimize enhances the accuracy of weather forecasts for district heating providers, leading to savings of up to €300,000 annually. By improving forecast accuracy, district heating operators can optimize energy production and distribution, reduce operational costs, and better participate in energy trading.

(PRESS RELEASE) VANTAA, 30-Apr-2025 — /EuropaWire/ — Vaisala, a global leader in environmental measurement technology, has introduced Xweather Optimize, a cutting-edge solution designed to improve weather forecast accuracy for district heating providers. By providing hyperlocal, network-specific weather forecasts tailored to each district heating network, Xweather Optimize enables more precise energy production and distribution, leading to significant cost savings.

District heating operators rely heavily on accurate weather forecasts to optimize heat production and delivery. By minimizing forecasting errors, Xweather Optimize helps reduce unnecessary boiler activations, adjust input water temperatures more precisely, and apply dynamic safety margins, all while ensuring efficient energy delivery, even to the most distant buildings. The solution also enables district heating providers to participate confidently in reserve markets to help balance the grid.

“By minimizing weather forecasting errors, we minimize heat prediction errors and enable companies to optimize cost-efficient heat production and distribution,” said Jussi Paanajärvi, Product Manager at Vaisala for Xweather Optimize. “Improved accuracy in the 1-to-48-hour forecasts also helps energy traders reduce the need to correct shortfalls and surpluses in the imbalance market.”

Xweather Optimize is already making a significant impact in Finland, where it is being used by district heating providers such as Fortum. The solution reduced forecasting errors greater than 2.5°C by 59%, resulting in substantial savings across several key areas, including heat production, network control, and energy trading.

Key savings include:

• €120,000 saved by optimizing heat production and minimizing unnecessary peak boiler initiations.
• €80,000 saved with effective network control by managing local constraints and bottlenecks.
• €100,000 saved in energy trading with more accurate bids and reduced need to correct shortfalls and surpluses in imbalance markets.

Xweather Optimize uses an easy-to-install wireless weather sensor network combined with software that continuously improves forecasts using machine learning. This solution helps district heating providers optimize their operations while reducing costs and supporting the transition to more sustainable energy systems.
