Inner Dowsing

Inner Dowsing is one of a paired Round‑1 offshore wind developments (commonly referenced together as Lynn and Inner Dowsing) located in the shallow North Sea off Lincolnshire, in the approach to The Wash. Built as a single construction programme under Centrica’s stewardship, the two adjacent sites together deliver about 194 MW and were commissioned in 2009. The project is notable as an early UK offshore wind deployment: consenting proceeded under a Transport & Works Order (2003) and the construction programme tested site-specific monopile drivability in chalk soils and shallow‑water wave transformation methods to inform safe installation windows. Construction activity began in 2006 with a notable test pile installation that informed pile design and installation logistics. Foundations were installed in 2007, subsea cabling (36 kV XLPE with fibre) was supplied under contract and turbine installation followed, with full commercial operation achieved in 2009. Commercially the project has passed through several ownership stages: originally developed by Centrica (and developed alongside RES), partial divestments followed the early operational years and the assets were included in bundle sales (GLID) in the 2010s; more recently Macquarie Asset Management moved to full ownership in 2024. The site remains operational and provides lessons on Round‑1 consenting, early offshore contracting routes and the transition of operational assets through institutional ownership. Note: transmission/OFTO ownership and grid‑stub lineage (TR1 / Blue Transmission Lincs Ltd) are not fully documented in the provided sources and should be followed up in dedicated offshore‑grid records.
