Serving Clydach

Clydach, at the head of the Swansea Valley, carries a population of approximately 7,500 and is dominated economically by a single employer. The Vale Clydach Refinery, also known as The Mond, is the largest nickel refinery in Europe. Founded in 1902 and operating as a top-tier COMAH site, it employs around 240 people producing 99.9% pure nickel powder and pellets that feed directly into the stainless-steel and EV battery supply chains.

The importance of Clydach nickel has grown sharply with the UK EV battery investment cycle. Gigafactory projects at Sunderland, Somerset and Coventry rely on supply chains that include Clydach product, and the result is explicit Scope 3 reporting pressure on The Mond from its downstream OEM customers. That in turn drives a commercial solar business case on-site that would have been unthinkable a decade ago.

Surrounding the refinery, the Swansea Vale trading estate hosts a concentration of SMEs, and the town centre runs a traditional high street along the A4067. Housing is a mix of terraced Victorian ex-industrial cottages and interwar semi-detached properties climbing the valley sides. Landmarks include the Swansea Canal, one of the earliest industrial canals in Wales at 1794 to 1798, the Mond Memorial in the town itself, and the Lliw Valley reservoirs a few miles north.

At a PVGIS yield of 950 kWh/kWp, Clydach is the same baseline as the rest of the Swansea Valley. The scale opportunity sits with The Mond and its supply-chain tenants. A 1 MW rooftop array on a refinery-adjacent logistics shed generates 950,000 kWh per year. At 25p/kWh blended self-consumption (Clydach has very high continuous process load) that is £237,500 of first-year benefit.

For domestic work in Clydach, the valley-sided housing stock and frequent proximity of mature trees means that SolarEdge panel-level optimisation recovers significant yield over a standard string inverter. We specify SolarEdge by default for this postcode precisely because shade losses would otherwise compromise generation.

The town sits 15 minutes from our Swansea base. We know the Mond gate procedures, we hold ConstructionLine for supply-chain framework tendering, and we have the industrial electrical scope to match.

FAQ

FAQs for Clydach

At 30p/kWh grid electricity, a 100 kWp system generating 95,000 kWh/yr with 70% self-consumption delivers around £24,000 of year-one benefit against c. £85,000 capex, a 3.5-year simple payback. Under Annual Investment Allowance first-year 100% relief, post-tax payback is closer to 2.6 years. South Wales yields 940 to 985 kWh/kWp/year depending on postcode, comfortably enough for commercial solar to be cashflow positive from month one with a PPA.
Yes. The Celtic Freeport, designated in 2023 and covering Milford Haven and Port Talbot, sits squarely inside our core coverage. We have active engagement with supply-chain tenants on rooftop solar and industrial electrical works across both port clusters, and we hold ConstructionLine accreditation for tier-1 main-contractor procurement frameworks operating inside the Freeport tax-advantaged zones.
G99 is the Engineering Recommendation governing how generation equipment connects to the UK distribution network. For commercial solar above 16 A per phase, you need G99 approval from your District Network Operator before export. In South Wales that is National Grid Electricity Distribution (NGED, formerly Western Power Distribution). Type A connections are the standard sub-1 MW route, typically 3 to 6 months in 2026.
Yes. Typical FLD scope covers LV distribution, SCADA and BMS containment, lighting, fire alarm, CCTV, access control, intercom and data, all under a single NICEIC Approved Contractor sign-off. Reference project: Cardiff Crown Courts refurbishment, approximately £50,000.
