Transforming Energy Risk into Predictable Savings for Logistics

Transform Energy Risk into Predictable Savings

This example is a typical use case for Wattstor’s customer success.

Facing strict grid limits and rising electricity costs, a major logistics and distribution business needed a way to expand renewable generation without investing in costly infrastructure upgrades. The organisation also wanted to stabilise long-term energy costs and accelerate progress toward net zero.

Wattstor stepped in with an integrated clean-energy system; combining solar generation, battery energy storage, and a smart energy tariff that transformed volatility into predictable, measurable savings.

Project Snapshot

The Challenge

The distributor faced several pressures as it prepared to expand operations at its new site. Limited grid capacity restricted how much onsite generation the business could add, making it difficult to scale renewable energy despite strong sustainability commitments. At the same time, rising and unpredictable electricity prices made budgeting increasingly difficult.

Traditional solutions would require expensive grid reinforcements or short-term energy contracts that offered little price stability.

Wattstor was tasked with delivering a smarter alternative that would:

• Maximise the use of onsite solar generation

• Store excess energy for later use

• Reduce grid reliance and associated costs

• Support long-term sustainability and net-zero goals

The Solution

Wattstor engineered a fully integrated onsite energy system tailored to the site’s operational profile and grid constraints.

• Solar PV sized to maximise onsite generation (1.67 MWp)
• Battery energy storage to capture surplus electricity and discharge during peak demand (2.4 MWh)
• Intelligent EMS controls to optimise consumption, avoid export limitations, and support continuous operations
• Price Protect, Wattstor’s smart long-term tariff providing cost certainty with a 20 p/kWh cap fixed for 25 years

The Price Protect tariff blends the flexibility of variable market pricing with the certainty of a long-term fixed cap, ensuring the customer benefits from cheaper periods while remaining protected by a fixed 20 p/kWh cap.

Together, this approach delivers stable, low-carbon power without exceeding existing grid limits turning energy volatility into a manageable, strategic advantage.

With this integrated approach, Wattstor created an energy ecosystem that supports both operational performance and long-term sustainability.

Without Wattstor, the business faces unpredictable costs and escalating grid reliance. With Wattstor, they achieve stable budgeting, protect margins and accelerate decarbonisation.

The Results

This project fundamentally transformed how the logistics operator manages and plans its long-term energy strategy. With Wattstor’s integrated system of onsite solar generation, battery storage, and the Price Protect tariff, the business achieved financial stability and operational resilience that traditional procurement models cannot deliver.

With electricity costs secured at 20 p/kWh for 25 years and 0% annual price increases, the organisation now has complete visibility over one of its largest overheads. This level of price certainty allows leadership teams to plan budgets with confidence, support long-term investment decisions and reduce exposure to market volatility.

The onsite renewable system has also delivered substantial economic and environmental impact. The solution provides £177,000 in annual cost savings, contributing to £4.4 million in net savings over the 25-year contract term. At the same time, it reduces grid dependence and avoids 21,000 tonnes of CO₂ emissions, directly supporting the company’s ESG and decarbonisation goals.

By combining predictable pricing, improved resilience and measurable carbon reduction, the logistics operator now benefits from a self-optimising energy ecosystem—designed to lower costs, support continuous operations and future-proof the business for years to come.

Financial Benefits

Wattstor’s Price Protect delivers long-term financial resilience by stabilising costs and shielding the business from market volatility. Key benefits include:

• Budget certainty: predictable energy costs for 25 years

• Margin protection: control over one of the largest operational expenditures

• ESG compliance: measurable CO₂ reduction supporting net-zero reporting

• Futureproofing: insulation from policy and price volatility

What This Means for Logistics Businesses

This case clearly shows that logistics operators can achieve long-term cost stability by securing predictable electricity prices with a fixed 20 p/kWh cap and zero annual price increases. With onsite solar and battery storage reducing reliance on the grid, logistics businesses can significantly lower their operating costs and avoid exposure to market volatility. At the same time, the system strengthens their sustainability performance, delivering meaningful CO₂ reductions that support ESG reporting and corporate decarbonisation goals.

By increasing resilience across key distribution sites and ensuring reliable, low-carbon power for essential operations, the solution provides logistics providers with greater operational certainty. Ultimately, this approach gives them clear visibility over future costs, improved energy security, and a stable foundation for long-term planning and growth.

By combining onsite renewables, intelligent storage, and a smart long-term tariff, Wattstor helps logistics operators turn energy risk into predictable savings—supporting sustainable growth and operational stability for the future.
