Electric coastal defence passes its test on a Sussex beach

The Environment Agency put electric construction vehicles through their paces on a Sussex beach and showed that clean technology can handle vital coastal defence work while cutting air and noise pollution. --- The context --- The work is part of annual efforts to protect the coast from flooding and erosion. Moving shingle along the beach maintains a natural barrier that protects homes, businesses and infrastructure, in an area where flood and coastal erosion risk management requires continuous work and heavy equipment. --- The facts --- From 12 to 16 October, an electric fleet shifted shingle from White Point in Eastbourne to North-east Beach in Sovereign Harbour. The fleet included a 22-tonne excavator, tipper trucks, hybrid bulldozers and 4x4s, and carried out the work as part of the annual coastal protection efforts. The Electric October trial showed that battery-powered machinery can cope with the tough demands of a working beach while cutting emissions and fuel bills. Throughout the week the team gathered data on productivity, reliability, battery performance, energy consumption, charging requirements and operator experience, all pointing to electric machinery being able to do the job. --- The positions --- Amber Carr, Pevensey Bay to Eastbourne Beach Manager, said in indirect terms that the technology is not just a good idea because it can work in a real operational environment, and that watching the fully electric excavator keep pace gave confidence to run operations more sustainably. Nick Gray, Area Flood and Coastal Risk Manager, said moving shingle is essential to protecting homes, businesses and infrastructure and that low-carbon technology can do that job just as effectively as traditional machinery. --- What remains unknown --- The results will help shape future decisions on lower-emission equipment in beach management, coastal construction, and flood and coastal erosion risk management across the country. The Pevensey to Eastbourne Coastal Management Scheme covers 15km of coastline in southeast England and will cost around £140 million over the next 10 years. The agency currently manages the 9km Pevensey stretch and from June 2027 will also take over the Eastbourne Frontage from Eastbourne Borough Council, with further works planned between 2027 and 2037. --- Unanswered questions --- Will the electric fleet be extended to other stretches of coast after this trial? What charging requirements would a permanent deployment on working beaches need? How will the battery and energy data shape future equipment decisions? --- EPM analysis --- The trial was a joint innovation project with industry partners testing low-carbon machinery on live coastal defence works. Its strength is practical evidence gathered on the beach itself, covering productivity and reliability alongside a significant reduction in air and noise pollution for communities and crews working on essential flood protection. 📌 EPM Take: In EPM's view, this trial matters because it links public benefit and a clean transition in essential work that cannot pause. If electric machinery protects the coast just as effectively with fewer emissions, less noise and lower fuel bills, flood defence gains a more sustainable tool. The task now is to turn the data gathered into careful deployment decisions, with charging and upkeep resolved, so the Sussex experience can guide comparable projects across the country without losing daily operational reliability on the beach.
