Total Power Requirement: 485 kVA for the WOLFF 320FB Tower Crane
Alternative Solution: 300kVA Genset/Dumarey Peak Power 200, Battery Pack (aircraft warning lights)
Burley Studios is a 189-studio-bed student accommodation project, situated near Leeds city centre in the busy student quarter. With this prime location, the project focuses on delivering best practices to minimise disruption to the surrounding community while maintaining high standards of safety and efficiency on-site.
The Burley Street site presented several challenges, including limited space for equipment, which would have been a challenge as power demands grew. Additionally, the busy urban area would benefit from
noise control to avoid disrupting nearby residents and businesses. Managing fuel consumption was also crucial, given the expanding scope of the project and the need for reliable, efficient power.
Limited space, rising power demands, noise control, and high fuel consumption.
WOLFF Onsite provided a compact and efficient solution with the Enertainer unit, paired with a Stage 3 110 kVA generator. This setup minimised space requirements and operated at a fraction of the noise level of traditional diesel generators, making it ideal for an urban site like Burley Street. The Enertainer comfortably powered the WOLFF 320B tower crane and handled additional power needs as they arose. The generator operated only as needed for recharging, averaging about 4.3 hours per day, dramatically cutting fuel consumption.
The Enertainer achieved exceptional fuel savings even while taking on additional power demands from the hoist and temporary site services. With this setup, no downtime was required, allowing for uninterrupted power during the generator’s 500-hour service. The need for a separate battery pack for aircraft warning lights was also eliminated, saving around £275 per week in hire costs.
“We have achieved significant savings on both fuel consumption and noise generation. Given the urban nature of the site, this aligns well with our goals for BREEAM certification and compliance with Considerate Constructors Scheme standards”

Disclaimer: This case study is based on 1 months of energy input data from a 110 kVa generator at a Torsion site in Leeds, conducted using the Enernet platform. Key calculations involved daily diesel consumption and generator running hours, assuming the generator operates at 50% capacity, 14.1 L/hr (confirmed by the site and AMPD team) with an efficiency of 2.9 kWh/L of diesel, a figure provided by the AMPD team based on the data obtained and the technical specifications of the generator. Averages were derived for daily, weekly (Monday to Sunday), and monthly (March and April) periods based on the available data, using complete datasets for each period. For comparison, a Stage 3 330kVa generator’s diesel consumption was analysed based on 50% utilization and 55 operational hours per week, based on industry expertise and customer experiences. Comparisons included average diesel consumption, costs (estimated using £1.30/L) and associated CO2e emissions (using the DEFRA GHG conversion tables, 2023). All technical data and consumption figures are based on specific site conditions and are for informational purposes only and do not constitute professional advice, results may vary based on different operating environments.
