Power Electrics' Annual Sustainability Report

21 Moorfields - London Construction

Power Electrics has recently provided 2 x 500kVA generators, fuelled with HVO (Hydrotreated Vegetable Oil), to Sir Robert McAlpine Limited, contractors working on the 21 Moorfields construction site in London.

The completion of Crossrail in 2019 is triggering a regeneration of the Moorgate area, and 21 Moorfields, located directly above an existing London Underground station and future Crossrail ticket hall, offer a major commercial opportunity. The development covers approximately 564,000ft2 and will become the new London Headquarters for Deutsche Bank.

Sir Robert McAlpine wanted to trial the use of HVO on-site to minimise their carbon footprint and reduce disturbance to the local community.

The Challenge

As with many large cities, London has strict emissions targets for new construction sites, set by the government to restrict the air pollution released into the surrounding environment. Sir Robert McAlpine wanted to go above-and-beyond the guidelines and provide an environmentally focused solution for their temporary power need.

“The trial has helped us demonstrate to our stakeholders that we are innovating to minimise environmental nuisance on-site and reducing our contribution towards climate change.”

The Solution

To help reduce the emissions, Power Electrics provided HVO fuel along with 2 x 500kVA generators. While being used on the 21 Moorfields construction site, HVO has saved an estimated 12.5 tonnes of carbon - roughly the equivalent of 3 personal flights from London to Sydney. Using the fuel also reduced NOx emissions by 12-22% and airborne particulates approximately by ~25-50% when compared to conventionally used diesel.

“Working with Sir Robert McAlpine to achieve their emissions targets was great. HVO is an easy solution for companies that want to reduce the Carbon, NOx and particulate emissions coming from onsite generators.”
