Ilmatar Energy is one of Finland’s leading developers and operators of renewable energy. With a growing portfolio of wind farms and solar parks, Ilmatar has established itself as a significant player in the Nordic energy market — and a direct participant in Nord Pool as a balance responsible party, managing its own energy trading in-house.
When Ilmatar first engaged Volue in 2018, the company was at an early stage — its operational requirements modest and well-defined. The initial contract, signed with a single wind farm SPV, covered only real-time data exchange: a targeted but critical service for a grid-connected asset. As Ilmatar’s portfolio expanded, so did the complexity of its operations. The pivotal shift came when Ilmatar decided to become a balance responsible party and join Nord Pool directly. This strategic move required a step-change in capability: the company needed robust energy trading infrastructure, round-the-clock technical monitoring, and the confidence to manage its own commercial operations from end to end.
Volue has accompanied Ilmatar through each phase of that growth. In 2021, following the earlier data exchange and Data & Forecast services, Volue delivered a comprehensive EMS implementation as a SaaS solution — the foundation for Ilmatar’s independent energy trading. This was paired with a full layer of operational services, including 24/7 technical monitoring across multiple wind parks and NC-ER data exchange compliance services.
By 2025, the solution had grown further still: AlgoTrader was added to support intraday algorithmic trading, Data & Forecast provides analytics and reporting, and Volue Asset Controller (VAC) enables precise asset controlling based on trading outcomes and TSO instructions. The overall setup has been shaped continuously to reflect Ilmatar’s philosophy — the company manages all trading itself and relies on Volue to provide the tools and services that make that possible at scale

Today, Volue’s solutions form an integral part of Ilmatar’s day‑to‑day operations. From the systems supporting the trading desk to the technical services ensuring continuous monitoring and regulatory compliance, the collaboration spans critical parts of the value chain and supports Ilmatar’s ambition to manage its operations independently.
Throughout the partnership, Ilmatar highlights Volue’s professionalism, breadth of offerings, and strong service mindset as defining qualities of the relationship. As Ilmatar continues to expand its renewable portfolio and operational footprint, Volue is well positioned to support the next stages of that journey — providing scalable software, reliable services, and long‑term expertise aligned with the company’s evolving needs.
