• Deliver price forecasting to support budgeting and long-term business planning, maintaining complex Excel and Power BI models.
• Provide regular energy market analysis and updates to executive stakeholders, translating complex data into clear business insight.
• Manage Power Purchase Agreements (PPAs) – overseeing invoicing, price validation, forecasting, and month-end processes.
• Collaborate across the business, including Finance, Energy Suppliers, and internal Energy & Carbon teams, to support energy procurement and pricing processes.
• Support broader energy and carbon initiatives, including portfolio development and net zero business cases.
