The offshore transmission asset connects the Westermost Rough offshore wind farm to the national grid and is a key component in supporting the UK transition towards a low carbon economy. This is the sixth Offshore Transmission Owner (OFTO) Licence awarded to INPP under the competitive tender process managed by energy regulator Ofgem, for the licensing of high voltage transmission links with offshore wind farms in Great Britain.

The Background

Offshore wind generation is a success story for the UK. Long-term government support has underpinned innovation and investment in the sector, helping to drive down costs while contributing to decarbonisation of the economy. The Government intends to build on the UK’s leading position with an aim to produce 40GW of offshore wind energy by 2030, up from c. 10GW in 2020. The UK has provided more support for offshore wind than any other country in the world and we anticipate that the technology will play a key role in helping the UK meet net zero by 2050.

To support this increase in offshore renewable energy generation, the Government identified that a new approach to developing transmission networks would be required and developed the offshore transmission regulatory regime. The Company recognised this opportunity and strategically positioned itself as one of the very few original consulting parties to Ofgem on the regime in 2009.

About Westermost Rough OFTO

TC Westermost Rough OFTO was awarded a transmission licence on the 4th February 2016 and took ownership of the assets on the 12th February 2016. The project connects the 210MW Westermost Rough windfarm located off the Holderness Coast in the East Riding of Yorkshire to National Grid’s 275kV substation at Hedon near Hull; via 27 kilometres of 150kV subsea and land cables including the associated onshore and offshore substations.

The Outcome

Project highlights include:

  • Operational and immediately yielding with no construction or refinancing risk
  • 20-year availability-based revenue stream with protected downside whereby potential deductions will be capped at 10% of base revenue in any year
  • Returns generated are fully linked to UK RPI and are not subject to any revenue or penalty exposure to windfarm performance or credit
  • Revenues are contracted by a subsidiary of National Grid, NGESO, in their statutory ring-fenced role as the National Electricity Transmission Systems Operator and protected by the Energy Administration rules (Energy Act 2004)
