SSEN Transmission contract for Eastern Green Link 5 ground investigation services

Transmission lines

We’ve secured a new contract under our framework agreement with SSEN Transmission to deliver ground investigation services for the onshore section of the Eastern Green Link 5 (EGL5) high voltage direct current (HVDC) cable route that will carry up to 2GW of clean energy between Aberdeenshire and Lincolnshire - enough to power two million homes.  

Awarded under SSEN Transmission's engineering framework, the contract will see our team undertake a comprehensive programme of ground investigation works along the proposed onshore HVDC cable route. The investigations will provide critical geotechnical and geoenvironmental data to support the design and development of one of the UK's major electricity transmission infrastructure projects being developed to ensure the efficient and effective connection and transmission of offshore wind.  

Planning and preparation works are well underway, with physical works scheduled to commence towards the end of August 2026. 

We will draw on our extensive experience in delivering complex ground investigation programmes for energy infrastructure, applying our multidisciplinary expertise to safely manage works across multiple sites while supporting the delivery of a resilient electricity network. 

Ralph Spernagel, Construction Director at Natural Power, said: "Ground investigations are a vital stage in the development of major infrastructure projects, providing the information needed to make informed engineering decisions and reduce project risk. 

“This contract reflects the confidence our clients place in our technical capability, project management expertise and commitment to delivering high-quality site investigations safely and efficiently. We look forward to working closely with SSEN Transmission to help progress this nationally significant project and support the UK's transition to a secure, low-carbon electricity network." 

Eastern Green Link 5 forms part of the ongoing investment in the UK's electricity transmission network, helping to increase network capacity and enable the connection and transfer of renewable energy to where it is needed most. Through the delivery of high-quality ground investigation services, we’re contributing to the development of infrastructure that underpins the country's net zero ambitions. 

The appointment marks the first call off under the new ground investigation framework between Natural Power and SSEN Transmission and reinforces our position as a trusted delivery partner for complex energy infrastructure projects throughout the UK.
