Manager, Economics (Energy Markets & Modelling) - Infrastructure & Capital Projects

We are looking for someone who wants to do more than operate a model as a black box. You will take ownership of model inputs and data, scenario design, calibration, validation, quality assurance, model runs and results interpretation. You will translate hourly outputs - including wholesale prices, capture prices, spreads, dispatch, load factors and revenues - into clear implications for transactions, asset valuations and investment strategy.

The role offers significant ownership and the opportunity to help shape a growing European modelling platform, working with senior A&M colleagues and specialists across our international network. Alongside modelling, you will lead workstreams, present to senior decision-makers, support proposals and thought leadership, and coach junior colleagues.

What makes this opportunity distinctive:

• Power modelling will be core to your day-to-day work and will directly underpin the conclusions we deliver to clients.
• You will work across fast-evolving technologies and revenue models, including renewables, battery and long-duration storage, flexible generation, interconnectors and new sources of demand.
• You will help extend our modelling capability beyond wholesale markets, linking PLEXOS outputs with analysis of intraday, balancing, ancillary-service and capacity-market revenues.
• You will combine deep analytical work with commercial due diligence, strategy and direct client exposure, with meaningful responsibility from the outset.

Activities and Responsibilities:

• Lead the development and application of fundamentals-based power-market models, with particular focus on PLEXOS, for GB and European client assignments.
• Own model inputs and assumptions covering electricity demand, generation capacity, renewable build-out, thermal retirements, fuel and carbon prices, interconnection, plant economics and policy or market-design changes.
• Design scenarios; run, calibrate and validate simulations; challenge results against historical data, market benchmarks and commercial logic; and maintain transparent, auditable quality assurance.
• Analyse hourly wholesale prices, capture prices, spreads, generation, dispatch, curtailment, load factors and asset revenues, identifying the drivers of value and risk.
• Apply modelling and market analysis to technologies including BESS and long-duration storage, flexible generation, renewables, hybrid or integrated flexibility portfolios, interconnectors and emerging electricity demand.
• Help develop complementary analysis for intraday, balancing, ancillary-service and capacity markets, and integrate multiple revenue streams into robust asset investment cases.
• Translate complex technical outputs into decision-ready conclusions for commercial due diligence, valuation, market entry, strategy and financing, presented through clear models, reports and presentations.
• Lead client workstreams, meetings and presentations; manage scope, timelines, risks and quality; and coach more junior team members.
• Contribute to business development, proposals, client relationships, market-facing thought leadership and the continued development of the team's analytical products and methods.

Qualifications:

• At least six years of relevant experience in power markets, energy economics, market modelling, advisory, consulting or a closely related field.
• A bachelor's or master's degree in economics, energy systems, engineering, mathematics, finance, data science or another relevant quantitative discipline.
• Demonstrable hands-on experience using PLEXOS or comparable fundamentals-based power-market modelling software. Strong PLEXOS experience is preferred.
• Experience configuring, running and interrogating models - not only reviewing outputs - including model inputs, assumptions, scenarios, calibration, validation and quality assurance.
• Strong understanding of power-market fundamentals and the drivers of wholesale prices, dispatch, capture prices and asset revenues; knowledge of GB and/or European market structures.
• Experience applying quantitative analysis to investment, transaction, commercial or strategic questions, with the ability to connect technical results to asset value and risk.
• Experience in one or more of renewable generation, battery or long-duration storage, flexible generation, balancing and ancillary services, capacity markets, interconnection or electricity-demand forecasting is desirable.
• Strong quantitative and data-handling skills. Advanced Excel is required; experience with Python, SQL or other analytical tools is highly desirable.
• Excellent written and oral communication skills, including the ability to explain technical analysis clearly to senior clients and non-specialists.
• Proven ability to manage workstreams and deliver high-quality work to demanding timelines; willingness to travel when required.

Competencies:

• Intellectual curiosity and a practical, hands-on approach to problem-solving.
• Rigour and attention to detail, with the confidence to challenge data, assumptions and model outputs.
• Commercial judgement: an ability to identify what matters to the investment decision rather than simply report analytical results.
• Clear and persuasive communication, turning complex analysis into concise, decision-useful advice.
• Ownership and resilience in a fast-paced environment, with sound judgement under pressure.
• Collaborative working style and ability to build effective relationships across disciplines, offices and seniority levels.
• Ability and willingness to coach junior colleagues and raise the quality of the team's analytical work.
• Entrepreneurial mindset, including identifying new client needs and helping turn modelling insight into propositions, thought leadership and follow-on work.
