SSEN to invest over £8m improving Petersfield and Fernhurst’s power supplies

Scottish and Southern Electricity Networks is to invest £8.4 million over a 19-month long project in 2020 to future-proof a significant section of its South East network.

Work gets under way during February 2020 to upgrade nearly 15 kilometres of SSEN’s electricity infrastructure serving the homes and businesses of Petersfield and Fernhurst, and all of the areas between the Hampshire town and West Sussex village.

The project, which will build resilience to the area’s power supply through the undergrounding of sections of cable and the refurbishment of the primary substation on Bedford Road in Petersfield, will also allow for future commercial and residential connections. The substation element of the project alone will provide power to 10,000 customers, with the overall programme of works keeping the infrastructure resilient and secure for decades to come, while the undergrounding of almost 15km of cable will provide increased security of supply by removing the reliance on the area’s overhead lines.

While the project is looking ahead to ensure a power supply that is fit for the future, it is also taking into account more immediate events, as SSEN’s Project Manager, Anthony Horne explains:

“During the planning stages of this project, SSEN was very aware of the events being held in the local area and have designed a cable route that minimises the amount of road works on main roads, while also looking to reduce the duration we are working around the local businesses and residents.

“The project team will work very closely with local businesses, residents and local authorities, and will continue to do so to ensure the smooth running and progress of, not just these upgrade works, but also the planned, local activities along the project route over the next 19 months.”

Network reliability is a key priority for SSEN and the customers its serves. Following a series of discussions, SSEN took the decision to make the investment to further improve network resilience, and future-proof its infrastructure for customer’s changing demands. This is part of SSEN’s commitment to taking a “you said, we did” approach to investing in its vital infrastructure. 

Prior to the commencement of this upgrade project, SSEN will publicise and hold a public engagement event for residents, business owners and interested stakeholders to allow for ongoing discussions on the programme of works. For the duration of the works, SSEN will be available to address any questions raised by the community, so that all parties involved are able to influence any possible impact these works may have. 


Scottish and Southern Electricity Networks (SSEN) has set up an online project page to provide regular updates on the £8 million improvement programme as it progresses and this can be accessed via -

Letter drops will be carried out to homes and businesses to update them on the phases of the project as it reaches their immediate area and, as some of the areas of the upgrade may lead to minor traffic management systems being used temporarily, details will be posted on
