Valmet Supplies Advanced Automation System for World's Largest Air-to-Water Heat Pump Plant in Helsinki

23 December 2025

Valmet, a leading provider of automation solutions for the process industries, has secured a significant contract to supply its advanced Distributed Control System (DCS) for Helen Ltd's innovative Patola air-to-water heat pump plant and two associated electric boilers in Helsinki, Finland. Announced on December 23, 2025, this project marks a pivotal step in Europe's transition to sustainable district heating, with the Patola facility poised to become the largest of its kind worldwide upon completion, boasting a full heating production capacity of approximately 30 MW.

The Valmet DCS will serve as the nerve center for the plant, enabling precise monitoring and control of the heat pumps and electric boilers. This system ensures flexible and efficient heat production, directly contributing to reduced CO2 emissions and supporting Helsinki's clean-energy ambitions. By optimizing operations, the technology promises stable heating prices for customers while maximizing energy efficiency. Jari Maaranen, Engineering Manager at Helen Ltd, emphasized the strategic importance of this initiative: "This project strengthens our long-term energy strategy by reinforcing operational performance and helping us deliver reliable, sustainable district heating to our customers far into the future."

Tom Bäckman, Senior Sales Manager in Valmet's Automation Solutions business area, highlighted the delivery's technical prowess: "We are proud to deliver the Valmet DCS to our trusted customer Helen, enabling advanced control and monitoring for their electric boilers and large-scale air-to-water heat pump plant - the first of its kind and scale worldwide." The system includes the web-based Valmet DNAe User Interface, which offers intuitive remote access to plant operations, facilitating seamless management even from off-site locations.

This order falls within Valmet’s fourth-quarter 2025 orders received, though specific financial details remain undisclosed. Delivery to the customer is scheduled for March 2027, aligning with the plant's construction timeline. Valmet's expertise in automation extends beyond this project, as the company provides comprehensive energy management solutions tailored for heat pump plants. These solutions integrate heat pumps, electric boilers, and thermal storage systems to balance supply and demand effectively, thereby enhancing grid stability in renewable-heavy energy networks.

Helen Ltd, serving 600,000 customers across Finland, specializes in electricity, heating, cooling, and renewable energy solutions. The company is committed to sustainability, with a firm goal to phase out combustion-based energy production by 2040. This Patola project exemplifies Helen's proactive approach to emission reductions and operational resilience. For plant operators and facility managers in Europe, this deployment underscores the viability of large-scale heat pump technology in district heating applications, particularly in cold climates where traditional fossil fuel dependency has been prevalent.

In the broader context of industrial automation, Valmet's involvement highlights the growing integration of digital control systems in power generation and distribution infrastructure. The DCS not only improves reliability and scalability but also supports lifecycle performance optimization, crucial for long-term investments in green technologies. Technology vendors and system integrators can draw lessons from this project on deploying robust automation in mission-critical environments. As Europe pushes for carbon neutrality, similar initiatives in Furnaces, Ovens, Heating and Airconditioning categories are expected to proliferate, driving demand for advanced control systems that harmonize efficiency with environmental goals.

The Patola plant's design incorporates cutting-edge features for responsiveness to heat demand fluctuations, a key challenge in transitioning to renewables. Valmet's solution addresses this through predictive analytics and real-time adjustments, minimizing energy waste and operational costs. Manufacturers and operators monitoring this development should note the emphasis on scalability, as the system's architecture allows for future expansions without major overhauls. This project also reinforces Finland's position as a leader in clean energy innovation within the Nordic region, potentially setting benchmarks for neighboring countries.

Looking ahead, the successful implementation of Valmet's DCS at Patola could catalyze wider adoption of air-to-water heat pumps across European urban heating networks. For B2B stakeholders in Power Generation, Distribution, Switchgears, Relays, this represents an opportunity to collaborate on hybrid systems combining heat pumps with existing grids. The partnership between Valmet and Helen exemplifies how strategic automation investments can align business objectives with regulatory pressures for decarbonization, ensuring competitiveness in a rapidly evolving energy landscape.
