GB Power Markets Lead

About the role

Commercial Operations is responsible for the assurance and governance of power market forecasts and assumptions that underpin Centrica Power’s investment decisions and operational planning. This senior individual‑contributor role requires a deep understanding of GB power markets, strong analytical skills and the ability to influence across a range of functions.

Work flexibly with the option to attend meetings at our Windsor, Reading or London offices.

• Lead governance of GB power market forecasts and assumptions, ensuring consistent standards, documentation and audit trails for investment, contracting and operational decisions.
• Define forecast input requirements for different decision contexts, determining when to use GF&E fundamentals, forward‑curve‑based views or evidence‑based adjustments.
• Translate GB market developments (design changes, code updates, new products, emerging behaviours) into clear forecast implications and testable hypotheses for Centrica Power.
• Conduct structured "material change" reviews to explain shifts in asset economics or portfolio outcomes and prevent unexplained variances from entering decisions.
• Align forecasts with operational reality by collaborating closely with Trading, Operations and asset teams.
• Maintain a single source of truth for GB assumptions, including inputs, rationale, sensitivities, limitations and refresh cadence.
• Deliver regular forecast and assumptions packs, drive cross‑functional alignment and raise risks with clear options.
• Develop decision‑specific alternative views where required, using simplified simulations, market data and historical analysis (without replicating full fundamental modelling).

• Degree (or equivalent experience) in a quantitative or analytical discipline.
• Relevant training in power markets, forecasting, analytics or risk/governance is advantageous.
• Substantial experience in GB power markets (market analytics, trading support, energy consultancy, utility/IPP commercial, market design/policy teams or forecasting).
• Demonstrable experience owning or supporting market view/forecast governance (release notes, change logs, scenarios, sensitivities, audit trails).
• Strong understanding of GB market mechanics relevant to asset valuation and operations: forward pricing, balancing/imbalance, constraints/local signals, Capacity Market, ancillary services and key code/market reforms.
• Ability to translate market developments into commercial implications for different asset types (energy storage, peakers, CCGT, renewables).
• Confident stakeholder engagement, with a track record of challenging constructively, reconciling differing views and driving decisions with clear rationale.
• Hands‑on experience shaping or challenging market forecasts, with sufficient modelling literacy to assess strengths, weaknesses and relevance.
• Skilled at producing concise, high‑quality decision outputs for senior audiences.
• High ownership, sound judgment and comfort operating in ambiguity.
