Wartsila (FI0009003727) restructures its energy storage operations into a new joint venture with Germany’s RCT Solutions GmbH and removes Energy Storage as a standalone reporting segment, according to a 15 June 2026 stock exchange release and today’s media overview from Helsinki. The shares trade on the OMX Helsinki exchange and change hands at 32.79 euros this afternoon per the company’s investor information page.

What Wartsila announced on energy storage

On 15 June 2026 Wartsila disclosed that it will establish a joint venture for its global Energy Storage business together with RCT Solutions GmbH, a specialist in advanced battery and storage technologies based in Germany, and will discontinue Energy Storage as a separate reporting segment once the transaction is implemented, according to the official stock exchange release on the company’s media portal. Wartsila’s global news and releases page outlines the joint venture announcement and the reporting change. The move follows several years in which energy storage solutions had formed a dedicated business unit within Wartsila’s portfolio.

The company positions the new structure as a way to combine its established energy storage footprint with RCT Solutions’ material and system expertise for batteries, power electronics and integration, aiming at a more scalable platform for grid-scale and hybrid projects, according to the description in the same release. The investor information section confirms that Wartsila continues to report under its core businesses while adjusting segment disclosure to reflect the energy storage joint venture. The joint venture is expected to take over Wartsila’s existing energy storage projects and pipeline, subject to customary regulatory and contractual approvals.

Thursday focus on the Wartsila shares and chart

With the Helsinki listing as international anchor, Wartsila shares trade around 32.79 euros today, up 1.74 euros compared with the previous close and representing a marked daily gain, according to the real-time quote on the investor information page dated 25 June 2026 at 15:50 local time. The company’s live investor quote table documents price, volume and index context for the shares. The stock is part of the OMX Helsinki index family, providing exposure to Nordic industrial and energy-transition themes alongside peers such as ABB and Siemens Energy on European exchanges.

Technical observers watch levels around the low-30-euro range as reference points for Wartsila’s recent trading corridor, taking into account that the current price sits comfortably above many medium-term chart lines used by market participants, even though detailed 200-day levels are not explicitly provided in the company’s own materials. Relative to the OMX Helsinki_PI, which stands at 13,728.90 points and shows a small decline today, Wartsila’s positive move stands out as a stock-specific reaction to its strategic energy storage update rather than a broad index-driven rally, according to the juxtaposition of price and index figures on the investor page. The same overview highlights Wartsila’s day performance against the OMX Helsinki_PI benchmark.

The product behind the Wartsila stock

Wartsila earns a significant share of its revenue from energy solutions for power markets, where its modular energy storage systems have become a flagship offer. These solutions typically combine lithium-ion battery packs with power conversion systems, control software and grid integration engineering to help utilities and industrial customers manage peak demand, stabilize grids and integrate renewable generation. According to Wartsila’s product communications, the portfolio also extends to engines, hybrid systems and lifecycle services for marine and energy customers, but the energy storage line now transitions into the new joint venture structure alongside RCT Solutions.
