Supply 2 Location Group Ltd. recently installed a 250kVA/575kWh Battery Energy Storage System (BESS) at one of the UK’s largest filming studios. When approached for this project, the team conducted a comprehensive assessment, evaluating not only running costs but also the broader environmental impact. After evaluating multiple application options, they determined that pairing a large BESS unit with a Stage V 150kVA generator for charging, was the most efficient and sustainable solution.
The BESS now powers the site 24/7, supporting approximately eight cabins and a workshop. This setup has reduced generator runtime by 73%, resulting in a significant decrease in fuel consumption and CO₂ emissions. By pairing the BESS with the greenest traditional generator available, this solution offers the closest alternative to a permanent grid supply. The pie chart below illustrates generator engine running times, as recorded by the telemetry data so far.
This package has been operational for nearly three weeks, resulting in a remarkable CO₂ reduction of 14,458 kg. And that’s before even considering the fuel cost savings. To put the impact into perspective, here’s a breakdown:
- The generator runs at approximately 70% load when charging the BESS and supplying site power, with a fuel consumption rate of 18ltrs per hour.
- If the generator were running 24/7, potential fuel usage over a 40-week period would amount to 120,960ltrs.
- With the current setup, projected fuel consumption over the same period is 30,240ltrs—a 75% reduction.
- Assuming an average diesel cost of £1.50 per litre, the estimated fuel savings over the project would be approximately £136,080.
This highlights the significant cost and environmental benefits of integrating a BESS with the latest Stage V generator technology. This installation was also carried out, tested and certified in accordance with BS7909:2023 & BS7671:2018 (A3: 2024) by Supply2Location’s inhouse electrical team – reinforcing the Group’s position as a true one stop shop for all temporary power requirements.
