The Beauly-Denny power line, a 137-mile electricity superhighway from Beauly to Denny, was once Britain's largest and most controversial power grid project, approved in 2010 after Scotland's longest inquiry. It aimed to bring renewable energy from wind farms to central Scotland but faced opposition for potentially damaging the Highlands' scenery. However, a report by BiGGAR Economics found no adverse impact on property prices since its operation began in 2015, with house prices in Beauly and Denny increasing in line with or exceeding local trends. The findings suggest that the disruption during construction caused temporary dips in property values, highlighting the need for faster planning to minimize uncertainty. As the UK plans to expand its energy infrastructure to meet climate targets, concerns about property values and community impacts persist, with calls for better compensation for affected homeowners.
