Portfolio company Volue appoints Stephan Sieber as CEO

13 Jan 2026 09:00 CET

(Arendal, 13 January 2025) Volue, the market leader in electrification software,
today announces the appointment of Stephan Sieber as Chief Executive Officer at
a pivotal moment for the energy sector.

Electrification is accelerating at historic speed. Weather-dependent renewable
power systems are becoming more unpredictable and data-intensive, and customers
face rising operational complexity. Stephan’s mandate is to extend Volue’s
market leadership and drive transformation and growth, unleashing Volue’s
expertise across data & forecasting, trading, optimisation & planning, and grid
operations – helping energy customers turn complexity into competitive
advantage.

Leadership for the next phase of growth and expansion
Stephan Sieber joins Volue following a year of stellar organic growth and
selective M&A, with the company well positioned to scale its impact across
regions and segments in 2026 and beyond.

“With electrification accelerating and system complexity rising, customers need
to partner with the best technology providers. Volue turns complexity into an
advantage, and the momentum with our customers right now is just the beginning.
I’m extremely excited about where the company, the market, and our customers
are, and how quickly the impact is compounding. We’re converting complexity into
competitive advantage, together,” says Stephan Sieber, CEO at Volue.

“Through his career, Stephan has consistently delivered exceptional results,
driving growth, leading complex strategic and operational transformations, and
building high-performing teams in some of the most competitive markets. He has
an extraordinary ability to understand customer needs, anticipate market trends,
and turn opportunities into tangible, lasting outcomes, earning him a reputation
as a market-proven leader. As Volue continues to define and lead, the Board is
unequivocally confident that Stephan’s unmatched experience and proven track
record make him the ideal leader to accelerate the company’s next chapter,
continuing its trajectory of unprecedented growth and cementing our position as
a market leader for years to come,” says Pete Daffern, Chairman of Volue.

“Over the past year, Volue has completed a strategic transformation becoming a
pure-play energy and grid software company. Stephan’s unique background, track
record and leadership experience makes him a perfect fit to lead Volue in its
next phase of development. We are excited to welcome Stephan, and we look
forward to working closely with him and the Volue team,” says Benjamin Golding,
CEO at Arendals Fossekompani.

A market at an inflection point
Europe is on track to double its electrification efforts by 2030, adding as much
capacity in the next five years as in the previous three decades. This surge,
driven in part by the electrification of transport and heat, and rising digital
demand from AI and data centres, is fundamentally reshaping energy markets.
Power systems are no longer centralised and predictable; they are becoming
distributed, volatile, and data intensive. Decision windows are shrinking,
markets transact continuously, and success now depends on real-time
intelligence, automation, and precision, capabilities Volue delivers to more
than 800 energy customers across Europe and Japan.

Enabling performance in volatile markets
Volue supports energy companies in operating their assets effectively under
these conditions through:
·     Real-time operations intelligence, enabling market anticipation and
execution, with 30% of Europe’s intraday market volume flowing through Volue
Trading solutions.
·     AI-driven optimisation influencing decisions across 500 TWh of annual
generation, representing 20% of Europe’s total power production, and positioning
Volue as the data to decision making leader.
·     Integrated multi-market execution, reinforcing Volue’s position as the
dominant partner of choice for 40% of Europe’s Independent Power Producers in
renewable integration.
