Developers reportedly altered the route of a £430 million energy interconnector after objections over potential disruption to the Welsh beach location used as Dobby’s grave in the Harry Potter films. The case highlights how popular cultural landmarks can influence infrastructure planning, although the diversion occurred during planning and the project has since been completed.

The Greenlink interconnector was intended to carry wind and solar power between Britain and Ireland, with an initial landing point near Freshwater West in Pembrokeshire. The fan-created memorial consists of stones, painted pebbles and socks; it has also prompted environmental concerns because such items can harm wildlife. The article does not state that the route change added a specific cost to the overall £430 million project.
