Willmott Dixon, Milton Keynes Museum

THE CHALLENGE

Better air quality, silent power, less fuel without costing more!

As one of the UK’s largest biggest construction companies, Willmott Dixon takes a highly responsible approach to sustainability with their approved suppliers. When looking into Milton Keynes Museum, the senior building manager on the site explained the challenges that would be faced when looking into a power solution. These included: 

  • noise pollution to be kept at a minimum, as it is in a residential area
  • to reduce the environmental impact on air quality while using diesel generators
  • to manage operational costs to this project

 

We are really pleased there is an innovative hybrid solution for temporary power that works. Thank you for your professional approach and safe installation service that has already given us great benefits on site. Better air quality, silent power, less fuel without costing more!”

THE SOLUTION

gridtogo

 

The site contained four bay modular buildings that housed offices, the canteen, toilets, store and security including CCTV. To accommodate the needs of the compound the largest unit Off Grid could provide was to be utilised. Furthermore, power 24 hours a day was needed as the site would run normally in the day but would also need critical supplies running during the night and weekend at a lower power demand.

Off Grid Energy helped establish the most appropriate solution for this by:

  • carrying out a power demand survey
  • proposing  the use of our new Powercube that can react via ‘load sensing’ and via a 7-day timer
  • consulting with the approved electrical contractor, to ensure all technical details were covered
  • Managing logistics, installation and power performance reports

The solution was a 45kVA generator was already in place on the Milton Keynes Museum site, to work in conjunction to this, the solution that Off Grid Energy put in place was a 30kVA, 60kWhr energy storage unit. This hybrid system would work to combat noise and air pollution, as this site is residential this was of significant importance. Consequently, our hybrid system would allow for the generator to be turned off during unsociable hours and this is when Off Grid’s Powercube would kick in.

THE BENEFITS

IMPROVED AIR QUALITY

With the reduction of running hours on the generator, the result was a dramatic reduction in CO2e production and vastly cleaner air.

SILENT POWER

Milton Keynes Museum is located in a residential area and the fact that the generator could be shut off during evening hours meant there wasn’t and noise pollution to disrupt neighbours.

LOWER FUEL CONSUMPTION

The reduction in fuel requirements for the generator resulted in significant cost savings.

REDUCED MAINTENANCE COSTS

With the battery system requiring virtually no maintenance and a significant reduction in generator running hours, the costs for maintenance are significantly lowered. What is more, better utilisation of the generator means that it is more reliable.

LONGTERM SOLUTION

By reducing the generator requirements the reduction in noise pollution, cumulative cost savings and impact on the environment offer a longterm solution.
