Energy is fundamental to food manufacturing; manufacturers rely on a consistent supply of power to keep operations running.
The UK Government identifies energy as one of the critical sectors which the food supply chain depends on, with disruption and price fluctuations capable of affecting businesses across the sector. The energy price shocks seen in recent years have demonstrated how quickly external events can affect food production costs.
For food manufacturers, greater energy independence can therefore form part of a wider strategy for building more resilient operations.
Why Energy Resilience Matters in Food Manufacturing
Food production often depends on energy-intensive processes, like refrigeration and cold storage running continuously or automated machinery and processing equipment requiring significant amounts of electricity during production.
This creates a reliance on a stable external energy supply. For businesses working to tight production schedules, unexpected disruption can have consequences beyond the energy bill.
Energy uncertainty and unpredictable energy prices can make it harder to forecast operating costs and more difficult planning for future investment.
The UK Food Security Report 2024 notes that energy remains a significant input for food manufacturing and that changes in energy prices can affect the stability of the wider food supply chain.
Supply Chain Risks Linked to Energy Dependence
With interconnected supply chains, an issue at one stage can affect operations elsewhere.
A business that relies entirely on imported energy has less control over how much it pays and where its energy comes from. Market conditions, international events and changes in demand can all influence energy costs.
The UK Government’s analysis of food supply chain resilience highlights energy dependency as an ongoing vulnerability. It also found that the energy price increases experienced between 2021 and 2024 contributed to higher input costs across the food supply chain.
This does not mean that every food manufacturer needs to operate independently from the grid. Instead, reducing exposure to external energy supply can give businesses greater control.
What Does Energy Independence Really Mean?
Energy independence does not mean becoming completely self-sufficient or disconnecting from the grid. For most food manufacturers, a more practical approach is to generate more of the electricity used on site while gaining a clearer understanding of how and when energy is consumed.
Solar PV can be an important part of this approach. Generating their own electricity allows businesses to use renewable power at the point where it is needed, reducing the amount of electricity that needs to be purchased externally.
This can reduce reliance on electricity purchased from the grid and provide greater visibility over future energy requirements. It also gives businesses more options when planning for changes in production capacity or energy demand.
Noble Green Energy’s work with food and beverage manufacturers is based around designing solar systems according to each site’s energy profile, rather than taking a one-size-fits-all approach.
How On-Site Generation Supports Food Production
For food manufacturers with suitable roof or ground space, solar PV can provide a source of electricity directly on site.
This can be particularly relevant where there is significant daytime electricity demand. Site operations can consume energy while solar generation is taking place, allowing businesses to use more of the electricity they generate themselves.
The potential impact will vary between sites as both system size and operating patterns need to be considered when designing a system.
Energy independence does not mean supplying 100% of a site’s demand through renewable generation. Reducing the amount of electricity purchased from the grid can still form a meaningful part of a resilience strategy.
The Role of Battery Storage & Energy Monitoring
Solar generation is only one part of understanding a site’s energy requirements. Regular monitoring can show when electricity is being consumed and how that compares with periods of solar generation.
This information can help manufacturers identify how effectively an existing system is being used and where further investment could be worthwhile.
Battery storage may also have a role where there is a mismatch between generation and demand. Surplus solar generation can potentially be stored and used later, increasing the proportion of generated electricity that can be used on site.
However, battery storage should only be considered alongside the site’s actual energy profile. Keeping on top of data can help provide the evidence needed to assess whether a battery could deliver value.
Building a More Resilient Energy Strategy
Energy independence is ultimately about increasing control over an essential business input for food manufacturers.
Together, on-site solar generation and battery storage can form part of a longer-term energy strategy designed around the realities of food production.
Rather than attempting to remove the grid from the equation altogether, manufacturers can focus on reducing their exposure to external energy costs and building greater certainty around future demand.
