New Grid Infrastructure Is The Precursor To Net Zero: Mark Neller, Arup

The UK's energy transition depends on much more than building renewable generation—it also requires a modern electricity network capable of connecting new power sources, supporting growing demand, and reducing energy costs.

This special episode of Inside Energy is produced in partnership with GRID, the UK's leading event for grid infrastructure, bringing together industry leaders to shape the future of the nation's electricity network.

In this episode, Stuart Broadley is joined by Mark Neller, Energy Business Leader for Europe, India, the Middle East and Africa at Arup, to discuss the UK's once-in-a-generation grid transformation. From the Great Grid Upgrade and long-term infrastructure investment to supply chain capacity, skills development and community engagement, they explore what's needed to deliver one of the country's largest infrastructure programmes.

The conversation also examines how digital technologies, flexible energy systems and smarter planning can improve grid efficiency, support economic growth, and create a pathway towards lower electricity bills. Along the way, Mark shares insights into Arup's role in major UK grid projects and why long-term policy certainty is essential for attracting investment, strengthening the domestic supply chain and accelerating the energy transition.
