# Wärtsilä Corporation — Flexible engine power plants, energy storage systems and lifecycle services > Wärtsilä Corporation is a Finnish energy and marine technology company. Its Wärtsilä Energy business supplies flexible engine power plants. On 1 October 2026, Wärtsilä completed the transfer of its former Energy Storage business to Valo, a 50/50 joint venture with RCT Solutions; Valo supplies utility-scale battery systems and controls. Wärtsilä undertakes full EPC contracts for selected power plants and has delivered storage construction and equipment packages, but many current orders are equipment, engineering, commissioning or lifecycle-service packages. This profile distinguishes documented EPC examples from technology supply and other project scopes. - **Legal name:** Wärtsilä Oyj Abp - **Headquarters:** Helsinki, Finland - **Founded:** 1834 - **Official website:** [Wärtsilä Corporation](https://www.wartsila.com) - **URL:** https://voltformer.com/epc-contractors/wartsila-energy - **Markdown:** https://voltformer.com/epc-contractors/wartsila-energy.md - **JSON:** https://voltformer.com/epc-contractors/wartsila-energy.json ## CEO and leadership profile ### Håkan Agnevall President and Chief Executive Officer President and CEO of Wärtsilä Corporation since 2021.
