A major UK-Ireland subsea and underground electricity interconnector project was rerouted after Harry Potter fans discovered its original path would run directly through the memorial site of Dobby the house elf on a Welsh beach.
When planners mapped out a multimillion-pound energy link between Britain and Ireland, they anticipated marine trenches, rocky seabed terrain, and standard regulatory hurdles. They did not expect an army of literary enthusiasts to mobilize over a fictional character’s final resting place. The green energy infrastructure project, designed to transport wind and solar power across the Irish Sea, ultimately bowed to pressure and shifted its underground trajectory to preserve a beloved cinematic shrine.
The £430 Million Greenlink Project and Its Coastal Landfall
The infrastructure initiative in question is the Greenlink interconnector, an over-and-undersea high-voltage power link costing £430 million or approximately €500m. The project connects EirGrid’s Great Island substation in County Wexford, Ireland, to a UK National Grid substation located in Pembrokeshire, Wales. According to interconnector planning details, the route spans roughly 160km underwater across the Irish Sea, complemented by approximately 25km of underground cable on the Irish side and 5km underground in Wales.
The engineering scheme reached a friction point at Freshwater West beach in Pembrokeshire. The scenic Welsh coastline serves as the real-world filming location for Dobby’s death scene in the 2010 fantasy film Harry Potter and the Deathly Hallows – Part One. In the years following the film’s release, fans transformed the dunes into a pilgrimage site, erecting a makeshift shrine composed of painted stones and left-behind socks. In 2022, the National Trust—Europe’s largest conservation charity—agreed that the tribute could remain in place, though officials urged visitors not to leave socks for environmental reasons.
How a BBC Wales Broadcast Sparked an Uproar
The conflict between modern electrical engineering and magical fandom began with a promotional broadcast. Simon Ludlam, chief executive of advisory firm Etchea Energy and project manager, filmed a segment with BBC Wales directly on Freshwater West beach. During the broadcast, Ludlam explained in great, graphic detail how the underground cable would make landfall, noting that the line would run up into the dunes before exiting into local roads.
That footage aired a couple of weeks later, prompting an immediate public reaction. The project team received hundreds of calls from furious Harry Potter fans who realized the proposed trench line cut straight through the memorial.
I said ‘Dobby, who’s Dobby? I don’t know Dobby?’ I said ‘he’s a fictitious character in a fictitious book, the whole thing is fictitious what are you talking about?'” [The colleague] said ‘no it’s very, very serious’.

Recognizing the intensity of the public response, Ludlam consulted with the project planners to map out an alternative path.
“Actually, we went quite close to some real Bronze Age remains, but we avoided Dobby’s grave. A lot of people were very happy about that, and the project’s now going and Dobby’s happy.”

Navigating Bronze Age Artifacts and Fictional Shrines
While the diversion successfully appeased fantasy enthusiasts, routing around the unofficial monument brought the energy link into proximity with actual history. Pembrokeshire council planning documents concerning the power link noted that archaeological trenches dug near the underground route contained the rim of an inverted pottery vessel whose fabric suggests a Bronze Age collared urn circa 1700-1500BC, typically associated with human burial.
The project marked an unusual operational hurdle for developers accustomed to managing environmental and historical preservation agencies rather than pop-culture landmarks. Reflecting on the near-derailing of a multi-million-pound interconnector, Ludlam observed that project leaders must remain flexible and thoughtful, adding that it was the first time he’d moved for a fictitious character.
Operational Status and Energy Capacity
Despite the coastal detour and public outcry, the infrastructure timeline remained intact. The interconnector completed construction in February 2025 and went live in 2025. The high-voltage energy link now carries electricity across the Irish Sea, with sufficient transmission capacity to power 380,000 homes without disturbing the sock-strewn sands of Pembrokeshire’s elf memorial.
