Northern Ireland Farm Solar Guide 2026: DAERA Grants, NIE Networks & Dairy Solar
By Rachel Okonkwo · 1 May 2026
Northern Ireland’s farm solar market has quietly become one of the most accessible in the UK. A DAERA capital grant covering up to 40% of costs, a streamlined NIE Networks connection process, and a farming sector dominated by high-energy dairy and poultry operations make the economic case straightforward. This guide covers everything a Northern Irish farmer needs to know about going solar in 2026.
DAERA Farm Energy Efficiency Scheme
The Department of Agriculture, Environment and Rural Affairs (DAERA) administers the primary grant route for farm solar in Northern Ireland. The Farm Energy Efficiency Scheme (FEES) provides capital grants of up to 40% on eligible solar PV equipment, with no minimum system size and a maximum eligible project cost set at £250,000.
Who qualifies
Any registered agricultural business in Northern Ireland with a valid holding number. Sole traders, partnerships, limited companies and farm partnerships are all eligible. Tenanted farms require written landlord consent. The project must serve an agricultural purpose — powering farmhouses alone does not qualify.
Application process
Applications are made through the DAERA online portal. You need three competitive quotes from NIEA-registered installers, a recent electricity bill, and a basic site plan. DAERA’s agricultural development advisors can provide pre-application advice free of charge through the Agri-Food and Biosciences Institute (AFBI) network.
Farm Business Improvement Scheme (FBIS)
FBIS offers larger capital grants for qualifying farms investing in productive infrastructure including energy systems. Solar PV paired with battery storage is eligible under the productivity tier. Maximum grant per project: £500,000 at 40% intervention. FBIS operates alongside FEES — farms can access both if investing in separate eligible items.
NIE Networks: grid connections in NI
Northern Ireland’s electricity grid is operated by NIE Networks, which is separate from GB’s DNO structure. G98 and G99 are the applicable connection standards, mirroring GB rules. Farm-scale solar systems above 11 kW typically require a G99 application to NIE Networks.
G99 timelines in NI
NIE Networks currently processes most G99 farm solar applications within 45–60 working days. The rural network in County Antrim, County Down and County Armagh is generally well-connected. Remote farms in upland County Tyrone and Fermanagh may encounter older 11 kV infrastructure with limited spare capacity, making a pre-application network study worthwhile.
SEG in Northern Ireland
The Smart Export Guarantee applies in Northern Ireland as in GB. Airtricity, Electric Ireland and SSE Airtricity offer SEG tariffs for qualifying MCS-certified installations. Top NI tariffs currently sit at 12–15 p/kWh for flat-rate contracts.
Dominant farm types and solar design
Northern Ireland’s farm sector is characterised by intensive dairy (some of the highest cow-per-hectare densities in Europe), poultry (broiler and egg), pig, and beef livestock. All three are high self-consumption operations — typically 65–85% — making solar highly cost-effective.
Dairy farms
NI dairy operations average 120–200 cows with year-round milking. Typical electricity consumption: 40,000–80,000 kWh/year. A 50–80 kWp rooftop system covers 50–65% of annual consumption. Battery storage (30–60 kWh) captures the solar surplus from afternoon milking for the evening bulk tank run.
Poultry units
NI has one of the highest densities of poultry houses in the UK. A typical 40,000-bird broiler house uses 120,000–180,000 kWh/year. 100–150 kWp systems with east-west split roofs (common on two-span poultry houses) achieve 70–80% self-consumption.
Planning in Northern Ireland
Planning policy in Northern Ireland is governed by the Planning (NI) Order 1991 and associated Policy Statements (PPS). PPS18 covers renewable energy and is broadly supportive of farm-scale solar. For buildings, Class C permitted development applies to non-domestic solar installations on agricultural buildings up to specified limits — check with your local Planning Authority (ARC21, Causeway Coast, etc.) for current permitted development thresholds.
Conclusion
Northern Ireland farm solar in 2026 combines an accessible DAERA capital grant, a manageable NIE Networks connection process, and a farming sector ideally suited to solar self-consumption. The biggest opportunity is dairy and poultry — both are high-energy operations with daytime load profiles that match solar generation almost perfectly.
