The project

Background

Shepherd Distribution operates a large logistics and haulage operation with a significant and consistent energy demand across their depot. With energy costs rising steeply, they wanted a solution that would provide genuine, long-term relief.

The solution

Alliant Energy designed a combined solar and battery storage system — a 108-panel array paired with a 62kW Sunsynk battery rack. The battery stores energy generated during the day for use during peak-rate evening hours, maximising the financial return on every unit generated.

The results

The solar + battery combination delivers £22,389 in annual energy savings — our most impressive single-site result. With a payback period of just 2.9 years and a 38.7% return on investment, this project demonstrates the extraordinary potential of combined solar and battery systems for high-consumption businesses.
