Head of European Energy Markets

Oak Tree Power Limited is a leading climate-tech company that works with grid operators to enable the transition to a fully sustainable electricity system.

We partner with commercial and industrial clients to reduce energy wastage and CO₂ emissions, and support grid operators through a variety of flexibility services.

Our vision is to empower clients to work towards a long-term goal of sustainability by fully embracing the concept of energy management.

Role Overview

Oak Tree Power is expanding beyond the GB market into European flexibility and ancillary services markets.

The Head of European Energy Markets will lead and coordinate this expansion - identifying, assessing, and prioritising the markets where Oak Tree Power's demand-side flexibility model can generate the greatest value, and then leading entry into those markets from first assessment through to live participation.

We've already made our first moves in Europe - some contracts are already secured, and the location and capabilities of our key customers will help point the way.

This is your opportunity to take that early momentum and run with it: developing the market value assessments that determine where we focus next - quantifying revenue potential across ancillary services, capacity mechanisms, and wholesale optimisation in target markets; and owning the practical route to entry: regulatory prequalification, TSO/DSO engagement, partner selection, and commercial launch.

You will work closely with the CEO and the senior leadership team, and alongside our existing European innovation activity, including our consortium role in Belgium's SCOPE project on secondary flexibility markets.

Key Responsibilities

• Market Value Assessment
• Build and improve market value assessments for target European markets, quantifying revenue potential for demand-side flexibility across ancillary services (especially m FRR), capacity mechanisms, and wholesale/balancing markets.
• Model market prices, volumes, saturation dynamics, and regulatory trajectories to produce defensible revenue forecasts and business cases for market entry decisions.
• Monitor European market and regulatory developments (ENTSO-E, ACER, national regulators, EU network codes) and translate them into commercial implications for Oak Tree Power.
• Maintain a prioritised European market entry pipeline, with clear go/no-go recommendations to the CEO and Board.
• New Market Entry
• Own the end-to-end market entry process for prioritised markets - from initial feasibility through prequalification, licensing/registration, and first revenue.
• Lead engagement with TSOs, DSOs, and market operators on market access requirements, product prequalification, and aggregation frameworks.
• Define the operational and technical requirements for each market entry (metering, baselining, dispatch, settlement) and coordinate internal teams to deliver readiness.
• Lead cross-functional market-entry programmes across Commercial, Operations, Product, Engineering and Data, ensuring that each market progresses from assessment to operational readiness and first revenue.
• Commercial Development

Support pricing, contracting, and revenue share structures for new European programmes.

• Represent Oak Tree Power in European industry forums, regulatory consultations, and working groups.
• Build and maintain relationships with TSOs, DSOs, regulators, and market bodies across target markets.
• Support European grant and innovation funding opportunities (Horizon Europe, national programmes), including contribution to consortium projects.
• Leadership & Cross-Functional Working

Contribute to the senior leadership team, shaping Oak Tree Power's international growth strategy.

Coordinate cross-functional squads (commercial, operations, engineering, data science, policy) to deliver market entries.

Build and lead a dedicated European markets team as the portfolio and revenues grow.

About You

You are an energy markets expert who is equally at home building a market revenue model as presenting an entry strategy to a TSO or a Board.

You know European ancillary services markets from the inside - the products, the prequalification hurdles, the aggregation rules, and where the real value sits for demand-side flexibility.

You are entrepreneurial, comfortable with ambiguity, and motivated by taking a proven GB business into new territory.

You can operate in French and/or German, and you enjoy the mix of analysis, relationship-building, and hands-on delivery that a market entry role demands.
