About your team
Centrica Power is at the forefront of the UK and Irish energy transition. Our portfolio spans flexible and conventional generation, renewable energy, energy storage and nuclear. With over £2bn of gross capital deployed, over 600MW in operation and a further 500MW in construction, we continue with our ambitious growth plans, building a Power business that will play a major role in the UK’s low‑carbon future. We’re involved in exciting projects – a 20% stake in the current UK nuclear fleet, a 15% investment in the development of Sizewell C, leading the UK’s first advanced modular reactor programme with X Energy and a growing renewables portfolio. Over the next five years we’ll accelerate investment as part of Centrica’s green growth strategy. This is your opportunity to help shape a business of major strategic significance to Centrica and to the UK’s energy mix.
About your role
Commercial Operations owns the assurance and governance of power market forecasts and assumptions used across Centrica Power for investment decisions and operational planning. This role ensures our forecasts are robust, evidence‑based, clearly documented and fit for decision‑making. As a GB Power Markets Lead, you’ll work closely with Group Fundamentals & Economics (GF&E), Regulations, commercial teams, modelling specialists and external partners to maintain consistent, defensible inputs for investment and operational planning. This is a senior individual contributor role with significant cross‑functional influence.
Location
We work flexibly in line with our Flexible First working arrangements. There will, however, be a requirement to attend meetings across our Windsor, Reading and London offices.
Responsibilities of the role
* Lead governance of GB power market forecasts and assumptions, ensuring consistent standards, documentation and audit trails for investment, contracting and operational decisions.
* Define the appropriate forecast inputs for different decision contexts, determining when to use GF&E fundamentals, forward‑curve‑based views or evidence‑based adjustments.
* Translate GB market developments (e.g. design changes, code updates, new products and 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 entering decisions.
* Align forecasts with operational reality by working 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 escrow risks with clear options.
* Develop decision‑specific alternative views where required, using simplified simulations, market data and historic analysis (without replicating full fundamental modelling).
* Focus on governance, assurance and decision‑use of forecasts, not day‑to‑day market monitoring or ownership of dispatch/optimisation models.
Here’s what we’re looking for
* Degree (or equivalent experience) in a quantitative or analytical discipline.
* Relevant training in power markets, forecasting, analytics or risk/governance is advantageous.
* Substantial relevant 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. Able to challenge constructively, reconcile differing views and land decisions with clear rationale.
* Hands‑on experience shaping or challenging market forecasts, with enough modelling literacy to assess strengths, weaknesses and relevance.
* Skilled at producing concise, high‑quality decision outputs for senior audiences.
* High ownership, sound judgement and comfort operating in ambiguity.
