John Pettigrew

John Pettigrew has led National Grid since 2016, managing one of the world's most critical energy infrastructure companies. National Grid operates the electricity transmission system in England and Wales, major electricity and gas distribution networks in the northeastern US (New York, Massachusetts, and Rhode Island), and interconnectors linking the UK to continental European power markets. The company sits at the heart of both the UK and US energy systems. National Grid is experiencing a fundamental transformation in its growth outlook. After decades of modest, inflation-linked earnings growth typical of regulated utilities, the company now faces unprecedented demand for grid investment driven by three converging forces: the energy transition (connecting offshore wind, solar, and battery storage requires massive transmission buildout), data center demand (AI-driven data centers require enormous grid connections), and electrification (heat pumps, EVs, and industrial electrification are increasing electricity demand). Pettigrew's management of the massive capital investment program (over £60 billion planned through the end of the decade), regulatory relationships in both the UK and US, and the balance between growth investment and shareholder returns are the primary drivers of National Grid's stock price.
