As an energy crisis and cost of living crisis collide, the Lincolnshire lorry mechanic and motorcycle racer investigates the past, present and future of British power stations to work out how the country makes its most valuable commodity of all - electricity. This first episode begins with Guy testing every piece of equipment in his workshop to find out which items use the most electricity. Horrified by what he's now having to pay for power, he tries to work out the reasons behind his big bills, and visits his local power station at Drax - which also happens to be the country's biggest.
Guy Martin visits the most important place in the entire national grid - the central control room - where electricity is bought, sold and routed every single second of the day. Temporarily tasked with the challenging job of keeping the country's lights on, Guy spends thousands of pounds in just a few minutes balancing the electricity supply-and-demand market, before his attention turns to the rise of renewable energy. He works with the army, who are pioneering a new solar-powered workshop, before embarking on the gruelling training required to become an off-shore wind farm technician.
Guy investigates the future of energy production, travelling to Orkney to look at how the Scottish islands are at the forefront of hydrogen research. He also joins the workforce at Europe's biggest building site and the Hinkley Point C nuclear power station, finding out why reactors are so expensive and take 10 years to build, and works inside Britain's most toxic site - handling nuclear waste inside the Sellafield facility.
