Frequently asked questions
Who owns STEAG, and how is it governed?
Since late 2023, STEAG has been wholly owned by Asterion Industrial Partners, a Spanish infrastructure fund manager. The purchase took the firm out of municipal hands and placed it under a professional asset-management structure. STEAG now operates with an independent board and investment committee, distinct from its former governance as a publicly backed utility.
Does STEAG still operate coal plants?
No. STEAG shut its last hard-coal-fired unit, Walsum 9, in 2022 and no longer holds any coal-generation assets. The company has systematically exited the coal business while reinvesting capital into renewable generation, battery storage, and hydrogen infrastructure.
What types of energy infrastructure does STEAG invest in?
The portfolio covers onshore wind, utility-scale solar PV, battery energy storage systems (BESS), gas-fired peaker plants designed for future hydrogen conversion, and district heating networks. The firm targets operational control of all assets rather than passive minority positions.
How does STEAG source its energy-infrastructure deals?
STEAG relies on in-house development capabilities and its legacy German grid expertise to originate projects. It acquires late-stage development platforms and brownfield sites, particularly in Germany, Benelux, and Eastern Europe, and carries them through permitting to commercial operation without relying on external developers.
Does STEAG raise external capital or invest as a principal?
Under Asterion, STEAG deploys balance-sheet capital as a principal for both organic project development and acquisitions. It does not publicly market a third-party fund vehicle, though Asterion's own limited partners benefit indirectly from STEAG's performance as a portfolio company.
