Wartsila ANCS

What Wartsila ANCS does

Wärtsilä Corporation is a Helsinki-headquartered, Nasdaq Helsinki-listed global technology company founded in 1834, with 17,900+ professionals operating from 199 locations across 78 countries. The business is organized around two core segments — Marine and Energy — and targets the decarbonization of marine transport and power generation through flexible engine power plants, multi-fuel propulsion systems, battery energy storage (BESS), exhaust gas treatment, and digital voyage and energy management software. Wärtsilä's installed base underpins a service-led aftermarket: roughly one-third of the world's large vessels and energy installations in 180+ countries use its technology, and more than half of revenue is recurring service revenue on a 12-month order-to-invoice ratio above 1x. Manufacturing is concentrated at the 90,000 sqm Sustainable Technology Hub (STH) in Vaasa, Finland, where every engine in the portfolio is produced.

The company earns revenue through four primary streams: (1) capital-equipment sales of engines, power plants, energy storage, and propulsion systems, typically delivered on 18–36 month project cycles via direct enterprise sales; (2) lifecycle services — field service, spare parts, upgrades, and retrofits delivered through 3,500+ field professionals; (3) performance-based contracts tied to measurable outcomes such as fuel consumption or CO2 reduction (e.g., the Solvang Clipper Eris onboard carbon capture demonstration at 70% CO2 reduction); and (4) digital software and voyage optimization via the Wärtsilä Voyage platform and GEMS energy management software. Pricing is custom-quoted on a per-project basis with multi-year service contracts, and the go-to-market is sales-led enterprise engagement, supplemented by digital self-serve via the Wärtsilä Online customer portal. Notable end customers include United Power (Bangladesh, 1,066 MW of Wärtsilä engines), Clearway Energy, GIGA Storage, Revera Energy, Solvang, Viking Line, Aqualectra, and a growing base of U.S. hyperscale data center operators.

Wärtsilä is in the middle of a major strategic reshaping. It has divested its ANCS, MES, Gas Solutions, and Water & Waste businesses (totaling approximately 665 MEUR of divested revenue across 2025–2026) and is forming a 50/50 joint venture with Germany's RCT Solutions GmbH for its 694 MEUR Energy Storage business, expected to close in Q3 2026. Concurrent capacity expansion of +65% at STH (a combined ~230 MEUR investment, completion Q1 2028) responds to an order book that reached a record 8,900 MEUR in Q1 2026 on the back of 22% organic order intake growth, including major data center power orders. The company is publicly listed on Nasdaq Helsinki under the legal name Wärtsilä Oyj Abp.
