As energy costs continue to challenge UK manufacturers, businesses across the automotive supply chain are reassessing how they power their operations. At its Hartlepool facility, TMD Friction – a global leader in friction technology and advanced braking solutions – has taken decisive action to reduce electricity price volatility while reinforcing its sustainability credentials.
Operating in an energy-intensive environment, TMD Friction faced growing exposure to fluctuating grid prices. At the same time, pressure to demonstrate environmental leadership within the automotive sector was intensifying. The brief was clear: deliver a large-scale, high-performing solar PV system without compromising safety, quality or day-to-day production.
A complex installation, carefully engineered
Working in partnership with Geo Green Power, the manufacturer commissioned a 668kWp rooftop solar PV installation – one of the installer’s largest projects of 2025. The system comprises 1,468 solar panels spanning approximately 3,000m² of roof space.
The complexity of the site required integration across two different roof types, each demanding specialist mounting systems. Careful planning ensured seamless installation across both structures, while maintaining operational continuity within the live manufacturing environment.
Given the scale of the project, enhanced health and safety controls were implemented beyond standard industry practice. A specialist rooflight protection system was installed to mitigate fall risk during both installation and future maintenance. This proactive, safety-first approach enabled the system to be delivered efficiently and responsibly, with minimal disruption to production schedules.
Turning energy into an asset
The results have been immediate and strategically significant. The system is generating approximately 598,000kWh of clean electricity annually – equivalent to fully charging nearly 10,000 electric vehicles each year.
Financially, the project is forecast to achieve a return on investment within just two to three years, with projected electricity cost savings of around £7 million over a 30-year period. Beyond direct savings, the installation reduces exposure to grid price volatility, transforming energy from a fixed operational overhead into a long-term strategic asset.
Supporting sustainable manufacturing
Alongside financial performance, the installation delivers substantial carbon reductions, strengthening TMD Friction’s environmental credentials and supporting wider decarbonisation goals within the automotive supply chain.
For manufacturers navigating rising costs, ESG pressures and competitive global markets, the project demonstrates how on-site renewable generation can deliver rapid payback, long-term resilience and visible sustainability leadership – without compromising operational performance.With large roof spaces and predictable daytime energy demand, many manufacturing facilities are well placed to replicate this model. As the sector accelerates towards net zero, commercial solar PV is increasingly proving to be not just an environmental initiative, but a commercially compelling investment.
