High daytime load
Production lines run 5-7 days a week, 12-24 hours — almost perfectly coincident with PV generation. Self-consumption rates of 75-90% are typical without battery storage.
Sector: Factories & Manufacturing
Solar Power Purchase Agreements for factories & manufacturing
Factories and manufacturing plants are the largest single user of UK commercial PPAs in 2026 — high daytime electrical load, large unshaded rooftops, and balance-sheet pressure to electrify out of gas have made solar PPAs the default no-CapEx route.
| 2026 typical PPA profile — factories & manufacturing | |
|---|---|
| System size | 250kWp–2MWp |
| Year-1 PPA tariff | 10–14 p/kWh |
| Demand-PV match | Strong — daytime production matches PV profile |
| Annual saving range | £35k–£280k |
Five drivers of PPA economics in factories & manufacturing
Large unshaded roof
Modern portal-frame factories provide 3,000-15,000 m² of unshaded south-facing roof — accommodating 250kWp-2MWp without structural strengthening.
CCL avoidance
Manufacturers on CCL main rates pay 0.6p/kWh extra on grid imports. Self-consumed PPA kWh avoid CCL — an additional ~£6k/yr saving on 100k kWh self-consumption.
Supply chain ESG pressure
Tier-1 customers (auto OEMs, retailers, pharma) now require Scope 2 disclosure. A signed PPA with REGO transfer is audited evidence.
Process electrification path
PPAs unlock heat-pump retrofits, induction heating and electric process upgrades — the path off gas.
Sub-verticals within factories & manufacturing
Every sub-vertical inside this sector has slightly different PPA economics — load profile, roof type, covenant strength all vary.
Food & drink manufacturing
UK food and drink manufacturers — bakers, brewers, dairies, fresh-produce packers — are the highest-volume PPA cohort within factories. Refrigeration + chilling
Automotive assembly & components
Tier-1 OEMs and tier-2 suppliers — Jaguar Land Rover, Nissan and their supply chain — drive automotive PPA adoption. Scope 2 mandates cascading through 2025-202
Plastics & rubber processing
Injection moulders, extruders, packaging manufacturers — process electrification candidates where PPA combined with heat-pump retrofit gives biggest impact.
Chemicals & pharmaceuticals
Cleanroom + process load = high self-consumption. ESG disclosure typically the lead driver; many tier-1 pharma now require Scope 2 disclosure of suppliers.
Aerospace & precision engineering
Clean-floor manufacturing with high daytime electrical demand; roof access often constrained but build-out economics strong.
Metals, foundries, glass & cement
Heavy daytime load; PPA + battery storage often economic for peak-charge management. Some sites also qualify for Energy Intensive Industry Compensation.

Funding a factories & manufacturing solar system: PPA vs the alternatives
How a PPA compares with the other routes a factories & manufacturing business can use to fund solar:
| Route | Upfront | Who owns & maintains | Best when |
|---|---|---|---|
| Solar PPA | £0 | Provider | No capital; want predictable 10–14 p/kWh power, off balance sheet |
| Cash / CapEx | Full system cost | You | Capital available; want lowest lifetime cost + 100% AIA in year one |
| Lease / asset finance | £0 down | You (after term) | Want eventual ownership but spread the cost |
| Grant-funded | Part-funded | You | You qualify for sector grant funding (often public sector) |

Watch-outs specific to factories & manufacturing
- G99 export limits: rural factory sites often capped at 50-100 kW; bigger systems need DNO upgrades.
- Roof structural assessment: portal frames over 20 years old may need surveying — budget £3-8k.
- Climate Change Agreements: some PPA projects affect your CCA energy use baseline — get specialist advice.
FAQs
PPA FAQs — Factories & Manufacturing
What's the typical PPA tariff for factories & manufacturing in 2026?
Indicative 2026 tariffs for factories & manufacturing range 10–14 p/kWh. The lower end applies to investment-grade off-takers on 25-year contracts with strong daytime self-consumption; the upper end applies to smaller systems or shorter terms. Our PPA calculator models your specific site.
How long does the PPA setup take?
From first call to commissioning typically 6-12 months. Indicative tariff in 2-4 weeks, site survey + heads-of-terms in 4-8 weeks, full contract in 8-12 weeks, build in 6-16 weeks. Larger systems with DNO upgrades take longer.
What system size suits factories & manufacturing?
Typical 2026 systems for factories & manufacturing range 250kWp–2MWp. Smaller sites stack with battery storage; larger sites may split across rooftop + ground-mount or multi-site sleeved structures.
Are there grant alternatives that beat PPA?
For public-sector sites, PSDS often gives a lower lifetime cost — but with lengthy procurement and 100% utilisation requirements. For energy-intensive industry, IETF stacks. For most commercial buyers, PPA wins on cashflow and admin simplicity. See PPA vs grant-funded.
What's the off-taker covenant requirement?
Most providers want investment-grade or strong-unrated covenant. For weaker covenants, parent guarantees, letters of credit, or shorter contracts can bridge. See off-taker covenant deep-dive.
