Scottish and Southern Electricity Networks (SSEN) reported on 19 April 2023 that it had completed a £710,000 upgrade of the electricity network at Lynes Common in Hythe, Hampshire. The work ran from July 2022 to the end of March 2023 and serves 20,000 homes and businesses in part of the town1.
The project replaced Lynes Common's switchboards and associated equipment, which SSEN said had come to the end of its working life, with modern switchgear intended to give a more resilient and flexible power supply1. SSEN is the distribution network operator for central southern England, the role covered in our guide to SSEN's networks, storms and priority services.
Aaron Reed, SSEN's project manager, said the upgrade formed part of the company's wider investment in Hampshire:
"Our Lynes Common network upgrade, which is part of SSEN's wider investment in the Hampshire area, has boosted the strength and security of power supplies for local homes and businesses across this area of Hythe for many years to come."
Two Planned Service Interruptions were scheduled to allow safe working, both contained within the Fawley Estate, with those affected notified in advance. SSEN stated that householders were unaffected by these interruptions1. The company said the work was carried out without road closures and with minimal interruptions to customer supplies1.
SSEN said it invests over £150 million a year in building resilience across its network. That figure includes around £20 million a year on tree cutting and maintenance, over £12 million targeted at refurbishing overhead lines, and over £2 million on Automated Devices intended to restore supplies faster after a fault1.
The announcement also restated eligibility for SSEN's free Priority Services Register, which provides assistance during a power cut. SSEN lists eligibility as: being deaf or hard of hearing; having a disability; living with children under five; being blind or partially sighted; having a chronic illness; using medical equipment or aids reliant on electricity; being over 60; or temporarily needing extra support1. The register is reached on 0800 294 32591.
Why it matters for households
Switchgear is the equipment that routes and isolates power on the local network. Replacing units that have reached the end of their working life is maintenance of the existing supply rather than a change to how a home is supplied, and SSEN has not reported any change to connection terms, capacity or tariffs at Lynes Common1.
For a household, the practical effect of this kind of work sits in reliability: fewer faults and, where faults occur, the prospect of supply being restored sooner. SSEN's stated aim for the new equipment is a more resilient and flexible supply, which it links to customers adopting low carbon technologies such as electric vehicles1. A stronger local network does not by itself remove the need for a home to manage its own demand, and no detail has been reported on how much additional capacity the upgrade releases or what it means for individual connections.
The interruptions that did take place were confined to the Fawley Estate and, according to SSEN, did not affect householders1. Homes that depend on electricity for medical equipment or that fall into the other listed categories can be recorded on the Priority Services Register, which is the mechanism SSEN operates for support during a power cut1.
What happens next
No further works, dates or follow-on phases at Lynes Common have been reported1.
