Sector: Farms & Agriculture

Solar Power Purchase Agreements for farms & agriculture

UK farms — dairy, poultry, pig, arable — are uniquely well placed for PPAs: large barn roofs, ground-mount land availability where wanted, and Defra grant stacking opportunities. The 2026 Farming Investment Fund actively encourages PPA-funded solar.

Five drivers of PPA economics in farms & agriculture

Barn + ground-mount

Cattle barns, grain stores, poultry sheds all suit roof-mount; underused arable land suits ground-mount.

Dairy load profile

Robotic milking + chilling + ventilation = 24/7 high daytime load.

Farming Investment Fund

Defra grant stacking with PPA possible on capex element.

Diversification income

Roof rental income stream in addition to solar savings.

Sub-verticals within farms & agriculture

Every sub-vertical inside this sector has slightly different PPA economics — load profile, roof type, covenant strength all vary.

Dairy farms

Highest self-consumption within farming — robotic milking + chilling + ventilation = 24/7 high daytime load.

Poultry farms

Continuous ventilation + lighting = strong PV match. Long roof shapes accommodate large systems.

Pig farms

Heating + ventilation — daytime load good. PPA combined with anaerobic digestion stack increasingly common.

Arable & mixed farms

Lower farm-load; export-heavy PPA structures. Grain drying provides seasonal peak coincident with summer PV.

Equestrian centres

Lights + arena + clubhouse load; mid-size systems often easier to plan than larger farm installations.

Farm PPA: solar power purchase agreements for agricultural businesses

A farm PPA puts solar on your barn roofs or spare land at no capital cost — the provider owns and maintains the system and you buy the electricity at a fixed 10–14 p/kWh (lower again for ground-mount). For dairy, poultry and pig farms the 24/7 daytime load from milking, chilling and ventilation gives exceptional self-consumption, so a PPA for an agricultural business in the UK typically delivers a strong year-1 saving with no asset on your balance sheet.

Typical agricultural deals run 100 kWp–5 MWp at 10–14 p/kWh. See the 145 kWp Lincolnshire dairy farm case study and 2026 PPA rates for tariffs by size.

Watch-outs specific to farms & agriculture

  • Asbestos roofs: many older barns have asbestos — must be replaced before solar installation. £15-25k/m² impact.
  • Wildlife / SSSI: ground-mount near protected sites needs habitats assessment.
  • AAONB / National Park: ground-mount in protected landscapes often requires very specific siting.

FAQs

PPA FAQs — Farms & Agriculture

What is a farm PPA?

A farm PPA (agricultural power purchase agreement) is a contract under which a provider funds, owns and operates solar PV on your barn roofs or land and sells you the electricity at a fixed price per kWh — typically 10–14 p/kWh, versus 28–32 p/kWh from the grid — over a 20–25 year term, with no upfront cost to the farm.

Can I get a PPA for an agricultural business in the UK?

Yes. UK farms — dairy, poultry, pig, arable and horticulture — are well suited to PPAs thanks to large barn roofs, available ground-mount land and strong daytime load. Dairy and poultry farms see the highest self-consumption. Grant stacking with the Farming Investment Fund is sometimes possible on the capex element.

What's the typical PPA tariff for farms & agriculture in 2026?

Indicative 2026 tariffs for farms & agriculture range 10–14 p/kWh (ground-mount cheaper). 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 farms & agriculture?

Typical 2026 systems for farms & agriculture range 100kWp–5MWp. 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.
