#378 Revisited: Designing Dinorwig – Inside Electric Mountain

In late 1973 the UK’s Central Electricity Generating Board gained parliamentary approval to build the largest and most difficult pumped storage hydroelectric power station in its history. It was the largest civil engineering contract ever awarded by the government and became the biggest construction project in Europe. Engineering teams had to burrow 750m deep into the Cambrian slate of Elidir Fawr mountain at Dinorwig, North Wales to create the underground power station and a 16km labyrinth of tunnels up to 10.5m in diameter linking upper and lower reservoirs. It’s scale and complexity pushed the limits of design and construction with engineers developing state of the art practices for rock reinforcement and concrete design and pioneering new construction methods. As the station celebrates 40 years of operation and looks ahead to a bright future as a battery for renewable energy, we speak with the people that planned, designed and constructed electric mountain hearing stories that have never been told before. Guests Kin Almond, supervising civil engineer, James Williamson & Partners John Armstrong, station manager Dinorwig and Ffestiniog, First Hydro James Arthur – senior engineer, James Williamson & Partners John Cowie – associate, James Williamson & Partners Chris Roberts, commissioning engineer, Central Electricity Generating Board (CEGB) Dyfrig Roberts – assistant engineer, James Williamson & Partners Robin Thomas – civil engineering technician, James Williamson & Partners Ian Waite – project surveyor, James Williamson & Partners Musical recording of “Tydi a Roddaist” used with the permission of the Caernarfon male voice choir who performed in the excavated machine hall in 1979.

#377 German Offshore Wind and the Mudflats of the Wadden Sea

Germany needs 70GW of offshore wind power connected to its grid by 2045, part of an estimated 300GW total capacity by 2050 for all of the nations bordering the North Sea. To achieve that ambitious goal it needs to run power cables through the Wadden Sea, the world’s largest system of intertidal sands and mudflats. The area is difficult to work within due to its dynamic environment, sensitive habitats, and bird nesting locations contributing to its World Heritage site status. The North Sea itself is no picnic, and extensive surveys need to be carried out, and actioned, at a pace unthinkable without the use of cutting edge technology and clever programme management. Beyond the challenging offshore conditions, developers must navigate competing uses of sea, including shipping routes, military practice areas and other designated use areas. This work can be carried out throughout the year with special rigs, uncrewed surface vessels and remotely operated vehicles. The resulting data is collated and analysed through cloud-based platforms and advanced AI tools to provide the optimal routes for power cables. The routes are refined and optimised as new survey information becomes available and additional sea-use constraints are introduced by the government and the market. In this episode Fugro, along with German grid operator TenneT, set out the challenges of working in the narrow German economic zone, as the industry races to meet these connection requirements ahead of a volatile geopolitical situation, and the hungry grid of Europe’s industrial powerhouse.

#376 Sandy’s Left Turn: Building a Resilient Manhattan

In October 2012, Hurricane Sandy turned sharply west and drove a storm surge into New York Harbor. Lower Manhattan flooded, a substation failed leaving more than 220,000 people without power, and damage across the wider region reached $65–70 billion. Protecting the Lower East Side from the next storm means threading flood walls, berms and deployable gates through one of the densest parts of the city. Defences sit above generations of utilities: sewers, water mains, power and telecommunications infrastructure. Works also had to avoid separating communities, while ensuring access to city parks and the waterfront. Engineering capacity is stretched by modern demands, and extreme weather poses increasing risks. Engineers need new approaches that enable them to evaluate and test more options, more quickly and effectively than ever before. Artificial intelligence, digital twins, and open data approaches provide the tools to do just that. These technologies can reduce tasks such as floodgate analysis from 30 hours to just 30 minutes. Across the infrastructure lifecycle, digital advancements are boosting efficiency and improving outcomes, transforming once cost-prohibitive concepts into the resilient infrastructure systems that society depends on.

#375 Innovation Champion – Engineering Matters Awards

In this episode, we celebrate Showerkap, winner of the Innovation Champion category in the Engineering Matters Awards 2026. The final award of the series. Judged by representatives from the Institution of Mechanical Engineers and Engineers Without Borders UK, the award recognises innovation across all of this year’s categories. Showerkap won gold for technology designed to reduce the water and energy wasted in showers. Its system uses sensors to monitor showers at fixture level, helping building operators understand water use and spot maintenance problems. Its patented valve technology can also encourage people to take shorter showers by gradually reducing the flow of water, rather than imposing a fixed limit. We learn about how the technology works and the role small changes in behaviour could play in tackling water waste. Guest Carly Hunt, Head of Strategic Partnerships and Board Member, Showerkap

#373 Lubricating the Lunar Frontier

Returning to the Moon is the next step, but staying there is the next leap. Abrasive and electrostatically-charged dust particles cling to every surface, and find their way into every mechanism, while a radiation-blasted lunar surface swings from 130°C in the sun to a brisk -173°C in the shade. To survive and thrive in the lunar wasteland, we will need habitat modules, power plants, autonomous rovers, drilling equipment and more: a fleet of machinery that needs to survive these hostile conditions. How we design these machines will be critical, how lubricants behave in extreme temperatures and hard vacuum is yet to be determined. But engineers are beginning to answer some of these questions.

#371 Revisited: Place is the Space for Growth

How should local and regional leaders encourage investment in their communities? Around the world, cities struggle with a legacy of industrial decline. In England, devolution of planning policy to mayoral combined authorities has allowed for regions like Greater Manchester to outpace national growth. But within regions, local areas can themselves fall behind, and require a joined up approach to planning and investment. When this episode was first recorded in September 2024, the focus was on how places can unlock investment by understanding their own histories, strengths and opportunities. Today, as the debate around Britain’s infrastructure ambitions intensifies, and the former Mayor of Greater Manchester looks increasingly likely to become the next Prime Minister, the intentions of the government in this area are worthy of speculation. The infrastructure industry is not waiting, an open letter from leading infrastructure and construction organisations, including the Association for Consultancy has called on the next government to prioritise long-term infrastructure delivery and provide greater certainty for investment. Could the principles of Manchester transfer to the nation at large? Will infrastructure be a priority for the incoming government? Can the required investment be funded? The engineering sector waits to see. Guests Andy Burnham, Mayor of Greater Manchester Susan Hinchliffe, Council Leader, Bradford City Council Tim Newns, MD, Levelling Up, Office for Investment, UK Department for International Trade Richard Robinson, CEO, UK and Europe, AtkinsRéalis John Rayson, MD for Northern Transformation, AtkinsRéalis Resources For the open letter from the ACE to Andy Burnham, click here

#370 The Forgotten Arsenal of the Ocean: Clearing Dumped Munitions

At the end of the Second World War, millions of tonnes of unwanted explosives and weapons were disposed of at sea. For decades, these dumped munitions lay hidden beneath the waves as time and tide passed over them. Now 80 years past that mass-dumping, corrosion has begun to expose the explosive chemicals inside these weapons casings. Lead, mercury and TNT breakdown products have begun to be detected in fish stocks throughout the affected waters. At the same time, the growth of offshore infrastructure such as wind farms is increasing the need to understand and manage hazards on the seabed. But dumped munitions are not the same problem as unexploded ordnance (UXO). Instead of finding isolated dangerous objects, engineers face vast areas containing thousands of items, requiring new approaches to detection, removal, containment and disposal. This is a question of new technologies, new approaches, and still yet, convincing people of the scale of the problem.

#369 Health & Safety Champion – Engineering Matters Awards

In this Engineering Matters Awards episode, we celebrate the winners of the Health & Safety Champion category, which recognises engineers who are changing how we protect people in some of the world’s most challenging environments. Engineering is often measured by what we build: the bridges, tunnels, infrastructure, and systems that shape our world. But true engineering excellence is also defined by how we build, and how we protect the people who make it possible. This episode explores how innovation, preparation, and predictive technology are helping to reduce risk and improve safety across the board. Our two award-winning entrants are: Scott Shipley, Director of Swiftwater and Whitewater Parks at Caliber Engineering, who is transforming emergency response training by creating realistic, controlled environments where first responders can prepare for extreme flooding scenarios. Monica Calle, co-founder and CTO of Geprode, is using predictive analytics to address one of underground construction’s biggest challenges: geological uncertainty.
