What we do
From a UK wide capability we provide a full range of substation services. From complete turnkey, value engineered solutions of major EHV substations to routine asset replacement or maintenance on secondary 20/11kV substations. Our service includes civil and structural design and construction of buildings and structures through to the detailed design, installation and commissioning of all primary and secondary electrical components and connections. We are experienced in brown field upgrades or extensions as green field new builds for brand new installations.
Who we do it for
Our highly skilled network design and fully authorised project teams are used on long-term frameworks with DNOs, including Northern Powergrid, UK Power Networks and Electricity North West. We also provide bespoke substation solutions to many energy critical industries including Renewable Energy developers, Transport infrastructure, Data Centres and Nuclear decommissioning.
Freedom has specialised technical design capabilities embedded within fully integrated project teams. We work in sectors such as Electricity Distribution, with the DNOs, Rail and Nuclear, and also deliver Contestable Connections. We are, therefore, able to harness best practice and innovation from these areas to benefit all of our clients. We operate to exceptionally high standards of safety, design assurance and commercial change control to give you total confidence in our service.
HV / LV Asset Replacement
With a broad, self-delivery capability to complete 20 and 11kV distribution substation replacements, Freedom delivers a seamless service by managing all engineering issues. These include: outage planning, adaptation or construction of new bases, plant logistics incorporating delivery to site, excavations, reinstatement and cable installation, HV jointing and all operational works by highly experienced SAPs who have been working in this field for many years. Freedom offers LV link box replacement, including turnkey project management to replace link boxes normally selected by the client for low Health Index reasons, as classified by the DNOs. The service includes a pre-visit to plan works safely and minimise customer impact, plant delivery, LV jointing and highway reinstatement.
HV / LV Maintenance
In general, switchgear has a proven record of reliability and performance. Over the years, manufacturers have issued details of modifications to be carried out on existing switchgear to improve its safety. It is essential that such switchgear work is carried out by competent engineers. Whilst equipment failures are rare, where they do occur, the results can be catastrophic. Freedom can offer a full range of services utilising experienced SAPs and fitting teams. Firstly, inspection (non-intrusive). Secondly, maintenance (intrusive), where maintenance under outage conditions will address mechanism defects, insulating oil contamination and deterioration, erosion of contacts and arc control devices. Thirdly, condition monitoring and assessment by partial discharge techniques, which can be used to detect and locate deterioration of solid insulation.
Existing EHV Substation Upgrade & Extensions
Providing complete substation design and build services, many of Freedom’s clients are facing major asset replacement programmes owing to the age profile of plant. Clients also require reinforcement work owing to general load growth driven by the economic recovery. Freedom has a unique mix of in-house civil, structural and electrical engineering resources that provide comprehensive solutions for major substation projects, including full turnkey delivery. With a truly integrated design and delivery service, we provide cost effective, innovative solutions for asset replacement or upgrade / extension projects at all voltages up to 132kV.
New HV Substations for Generation or Load Connections
We are very experienced in HV and EHV connections where substation work is required. The UK has a very high penetration of wind and solar farms requiring a connection to a distributor. Freedom has worked with DNOs and renewable energy generators to ensure these significant investments are connected on time. We understand the deadlines this industry works to and the importance of thorough planning and risk management. Our service incudes design, installation and commissioning of all substation assets up to 132kV, including the interface protection arrangements.
Freedom can assist in the response to a catastrophic failure of major substation plant, such as transformers or switchboards. These failures can result in damage to buildings and cables from the resultant fire or explosion. The first response service includes: making the perimeter secure and safe, installing welfare facilities, carrying out temporary building repairs, as well as emergency switching and jointing to restore supplies to customers.
