Is Solar a Threat or Benefit to UK Food Security?

Energy is one of the most important resources to keep food production moving. However, with farmers under pressure to produce more efficiently, manage rising costs, respond to changing weather patterns and maintain long-term business resilience, UK food security is an understandable concern.

Pig and poultry farming is an energy-intensive sector with power required for ventilation, heating, lighting, refrigeration, feed systems, water management and wider site operations. At the same time, the UK needs more reliable, affordable energy which has led to the growing debate around solar development on agricultural land.

So, is solar a threat to UK food security or can it support it? This depends on a variety of different factors we will explore in this article.

Addressing Concerns of UK Food Security

Concerns about food security should be taken seriously; especially considering the current Middle East conflict and increase in extreme weather events. Productive agricultural land has a vital role to play, as the Sustainable Food Trust states, so the best land should be managed carefully.

This is why solar development needs to be considered on a site-by-site basis. Not every farm is suitable or needs the same system, and not every project should be designed as a large-scale, export-led solar farm.

For some farms, the most appropriate solar opportunity may be rooftop panels on poultry sheds, pig units, grain stores or other agricultural buildings. For others, it may be a ground-mounted system on lower-grade land, field margins, non-core areas or parts of the site that are less productive.

Why Land Quality, Siting & System Design Matter

Land quality, existing farm infrastructure, energy demand and long-term business objectives should all be assessed to determine which system is the right fit. Starting with land assessment, the most suitable approach will depend on agricultural land classification, current land use, topography, access, grid capacity, planning considerations and proximity to electricity demand.

Large sheds and agricultural buildings can offer useful space for solar panels, allowing energy to be generated without taking land out of production. This can be a practical route for farms that want to reduce energy costs while keeping land focused on livestock, food production or other agricultural uses.

In other cases, a ground-mounted system may be suitable where land is lower-grade, less productive or difficult to use efficiently. This can allow a farm to create value from parts of the land base that are not central to food output.

Solar energy production doesn’t have to operate in isolation either. Battery storage is another option to help farms make better use of the power they generate, particularly where demand varies during the day.

Also, if the farm is located close to a high-energy facility such as a food processing facility, manufacturing site or cold storage operator, a new multi-use development, a private-wire or direct-wire model may be relevant.

How Energy Generation Can Sit Within A Wider Farm Strategy

A farm strategy might include livestock production, diversification, energy generation, environmental improvements and long-term asset planning. These elements can work together when they are planned carefully and solar can support this by:

• Reducing exposure to energy price changes by generating electricity on site
• Creating an additional income stream where export, lease or private-wire opportunities are viable
• Helping reduce carbon emissions and work towards sustainability targets
• Improving long-term cost control

There may also be a supply chain advantage as food producers and manufacturers are under growing pressure to understand and reduce emissions across their operations. Farms that can demonstrate practical steps towards greener energy may be better positioned as this pressure continues to build.

How Solar Can Support Farm & National Resilience

Food security depends on whether farms can remain commercially viable but it’s difficult to plan ahead where there’s rising input costs, labour pressures, extreme weather and energy price volatility.

The Solar Energy UK Farming Sustainably Report highlights how solar can help farms respond to the economic and environmental pressures affecting agriculture. It supports farm resilience by giving greater control over part of their energy supply needed to power operations every day.

By generating electricity close to where it’s needed, solar reduces reliance on imported energy and improves long-term cost visibility. This could mean using solar to power ventilation, lighting, heating systems, egg packing facilities, cold storage, feed handling or wider pig and poultry farm operations.

A more resilient farm is better positioned to continue producing food. In the same way, a national energy system with more renewable generation is better prepared for future demand.

Solar Supports UK Food Security

The debate shouldn’t be about whether solar belongs in farming at all, but about how it supports the farm as a whole.

Agricultural businesses, such as pig and poultry producers, often operate with tight margins and consistent energy requirements. Therefore, if solar helps reduce exposure to volatile energy prices and improves operational resilience, then it can play a positive role in supporting food production.

Food security relies on productive land, but it also relies on financially resilient farms, affordable energy, secure supply chains and the ability to adapt to future pressures. Our involvement with Sustainable Food Factory reflects the growing focus on energy resilience, cost control and decarbonisation across food and beverage operations. For landowners near major energy users, solar may offer opportunities that go beyond the farm boundary while still supporting the wider food system.

As part of the Noble Foods Group, Noble Green Energy is the only solar EPC embedded within the food and agriculture sector. We support farmers and landowners by helping them understand what is possible on their site. This includes assessing rooftop potential, land suitability, grid constraints and private-wire opportunities. Get in touch with us today to find out more.
