Job description

National Grid is one of the world’s largest investor-owned energy utilities, with a significant presence across the UK and north-eastern United States. The Group owns and operates critical electricity and gas infrastructure, connecting energy producers with homes and businesses and supporting the reliability and development of the energy system.

The business is organised around five principal areas: UK Electricity Transmission, UK Electricity Distribution, New York, New England and National Grid Ventures. This structure reflects the Group’s focus on regulated energy networks in the UK and US, alongside selected infrastructure investments such as electricity interconnectors.

National Grid’s strength lies in the scale and importance of its energy networks. As electricity demand rises, driven by renewables, electrification and data centres, the Group is investing to expand capacity, strengthen resilience and connect new sources of energy generation and demand.

Investment is a major growth priority. National Grid plans to invest at least £70bn between 2026/27 and 2030/31 across its UK and US networks, supporting energy security, economic growth and the transition to a more electrified energy system.

The role ensures that customer connection projects are developed to a consistent, auditable and robust standard, with credible engineering solutions, clear customer propositions, compelling cost and schedule evidence, and appropriate regulatory, commercial and governance assurance.

The role provides critical support to Executive leadership by creating clarity across a high-complexity, high-volume and fast-changing portfolio. It will establish a clear view of customer portfolio maturity, risks, constraints, options and interventions, enabling better decisions, stronger customer confidence and more predictable transition into delivery.
