Commercial solar across Teesside and the Tees Valley

Teesside is where Britain is spending its industrial-energy money. Teesworks — 4,500 acres on the south bank of the river at Redcar, the heart of the UK’s largest freeport and the biggest brownfield site in Europe — is being rebuilt from steelworks ground into an energy manufacturing zone. On it, bp and Equinor’s Net Zero Teesside Power — a gas-fired station of up to 860 MW designed to run with carbon capture, aiming to be the first of its kind at scale anywhere — took its final investment decision in December 2024 and is under construction. Next door, SeAH Wind’s monopile factory — an 800-metre-long building billed as the world’s largest of its kind, an investment that has grown to around £900 million — has risen on the same site, and across the river the 2,000-acre Wilton International complex carries the process-industry cluster: SABIC, Ensus, Alpek Polyester, Huntsman and the rest.

None of which pays your electricity bill. The billions landing on Teesworks decarbonise the grid eventually; the roof over your warehouse in Stockton or your workshop in Middlesbrough could be cutting your own costs from the month it is commissioned. That gap — between the region’s energy headlines and an ordinary business’s energy invoice — is the entire case for rooftop solar here, and it is the work we come down the A66 to do.

A word on geography, because Teesside’s is genuinely confusing. This is not one council area but five unitary authorities — Middlesbrough, Stockton-on-Tees, Redcar & Cleveland, Hartlepool and Darlington — with a combined population just over 677,000 at the last census, working together as the Tees Valley Combined Authority under an elected mayor. Practically, that means four different net-zero programmes on four different clocks: Middlesbrough has committed to a carbon-neutral council by 2029 and town by 2039, Stockton targets its own operations by 2032, Darlington brought its council target forward to 2040, and Hartlepool adopted a 2050 net-zero strategy in late 2023. Wherever your building sits, the local authority setting its planning weather wants commercial decarbonisation to happen — they just disagree about the deadline.

The roof stock is the other reason this patch earns its own page. Teesside industrialised early and re-industrialised often, so its commercial buildings run the full span — post-war workshops on Middlesbrough’s riverside estates, 1980s trade stock along Portrack Lane, brand-new advanced-manufacturing units and million-square-foot logistics sheds by the A66. Most of it is steel portal frame under profiled metal sheet, which is the roof type we would choose if we were choosing: arrays mount on clamps or sealed crown fixings, installation is measured in days, and on many profiles the sheet is never pierced at all. Yield is North East honest — plan on 800–950 kWh a year for each kWp installed, the shallow-pitch sheds nearer the bottom of the band — and payback for a business using most of its generation in the daytime sits in the five-to-eight-year planning range we work through openly in the calculator.

Now the honest bit about us. We are not a Teesside firm; we are a County Durham electrical contractor — based at St Helen Auckland outside Bishop Auckland, thirty years in the trade — and Teesside is a working drive, not a walk. Darlington is about twelve miles from the yard; Stockton, Middlesbrough and Hartlepool are twenty to thirty miles down the A66 and A19 corridors. We survey, install and come back for warranty work across all of it, and we would rather tell you plainly that our vans start in DL14 than imply an office we do not have. What thirty years of electrical contracting does mean, anywhere on this coast: if the survey finds a distribution board with no spare ways or a fixed-wire test overdue before anything connects, the same firm deals with it — one contractor, one accountable name.
