Job description
### About the role Octopus is building a new business line delivering low-cost, reliable, clean energy and faster speed-to-power for datacenters and large industrials. The deals are first-of-a-kind: private wire, behind-the-meter generation and storage, flexible load, novel grid connections. This is a quantitative role with direct exposure to large-scale innovative power projects. You'll own the project model, build pricing strategies and directly participate to final investment decisions. ### What you'll do - **Own the project model** for each opportunity - generation, BESS, flexible load, network cost; capex, opex, revenue stack, IRR, downside cases. Build project-specific models while developing toolings and standard assumptions to support our growing pipeline - **Price the offer.** Turn a customer's load profile and reliability requirement into a deliverable price and structure - tariff, PPA, tolling, availability-based - and show which one allocates risk sensibly for both sides. - **Value the flex.** Model storage and flexible load across wholesale, Balancing Mechanism, ancillary services and Capacity Market. Quantify network charges (TNUoS, DUoS, BSUoS), curtailment and connection options. - **Develop the business case.** Build internal and external presentations to support from indicative customer proposals to project final investment decisions. - **Track the portfolio and read the market.** Monitor live projects against approved cases - spend, milestones, connection dates - and identify early and quantify regulatory change (connections reform, REMA, network charging). Support term sheets and diligence from indicative to signed. ### What you'll need - 2–5 years in a numerate commercial role - infrastructure or renewables development, project finance, banking, energy trading or origination, strategy or energy consultancy. - Financial modelling from first principles: DCF, IRR, scenarios and sensitivities. You can build a model someone else can follow and eventually develop it as a standard tool for other team members to use. - Advanced knowledge of GB/European power markets, and how network and connection costs land on a project. - Advanced Excel and Python - Able to take a messy, incomplete problem to a clear recommendation - Quantitative degree - economics, engineering, finance, maths, physics - or equivalent experience. It would be nice if you have... Datacenters, large industrial load or behind-the-meter/private wire projects; BESS revenue stacking; a PPA, tolling or connection agreement taken to signature; Aurora, PLEXOS or equivalent.
