01
Refrigeration demand
Understand the energy needed to maintain temperature control, including the pattern of demand across your operating day.
Energy storage for cold storage
Keep the cold
Rethink the energy
Help manage energy costs, support electrification and plan for the demands of your cold-chain operation.
Your operation comes first
Refrigeration.
Transport.
Your next phase.
Bring today's demand and tomorrow's plans into one energy conversation.

Energy costs
Explore how banked energy could help manage exposure to expensive electricity periods.
03
Connection constraints
Assess how storage could help manage demand within the limits of your existing connection.
04
Electrification plans
Consider electric HGV charging, trailer refrigeration and future site expansion alongside existing loads.
The Sherwood FAB — Free Air Bank
We use air and water
to store energy
Bank surplus renewable energy on site. Use it when it matters.
The FAB uses surplus renewable electricity to bank energy for later use, helping businesses make efficient use of renewables, expand electrification and reduce energy costs.
Renewable electricity can come from on-site generation, the grid or both. The system is configured around your site's energy supply, demand and available connection.

01 / GENERATE
Renewable electricity, on site or elsewhere
Solar and wind generate electricity when conditions allow — not according to your site's timetable.
02 / BANK
Bank the surplus on site
The FAB stores energy from surplus renewable electricity available to your site, ready for later use.
03 / USE
Use it when it matters
Use banked energy when demand rises, renewable generation falls or grid electricity is more expensive.
Configured around your operation
Start with today's needs
Plan for what's next
Think building blocks. Configure the FAB around your current requirements, with a route to add storage capacity as your operation develops.
Look beyond electricity alone. Discuss whether cooling, heating or compressed-air outputs could add value to your site's configuration.
Plan your next stepDemand, timing and operating priorities
Review refrigeration loads, charging schedules, seasonal changes and the demands that occur at the same time.
Any role in resilience or backup supply needs a specific assessment. Energy storage alone is not a guarantee of uninterrupted refrigeration.
Site connections and grid opportunities
Assess available import and export capacity alongside your energy supply. Storage does not increase the physical capacity of the connection or guarantee that an upgrade can be avoided.
Explore potential grid-balancing opportunities separately, subject to connection limits, system capability and market arrangements.
Footprint, integration and future growth
Consider positioning, electrical integration, maintenance access and space for expansion, alongside the operational requirements of your site.
