WineWorks had set goals to improve their sustainability profile, but without timely visibility of electricity, LPG and water consumption at their Marlborough plant, the team was struggling to meaningfully improve their operational performance and reduce their Scope 2 emissions. You can’t manage what you don’t measure. 


ESP completed a Type 2 energy audit and installed targeted electricity metering, supported by EECA funding. The analysis identified a range of efficiency opportunities including:

  • lighting,
  • compressed air,
  • nitrogen and,
  • after-hours usage.

The team also implemented detailed utility monitoring software, which identified how production usage and other factors impacted energy use. This allowed for the development of accurate, up-to-date business cases with clear cost/benefit analysis.


In the first 12 months, WineWorks reduced their expenditure in this arena by 5%, with 15% to 20% planned in the near future as a result of upgrades to the nitrogen and air compressors.

The audit also resulted in lighting replacement and the development of a preventative maintenance plans to check and fix air leaks for long-term efficiency.

Meanwhile, monitoring has provided the information needed to demonstrate to staff the benefits of improved shutdown procedures and the ability to continuously monitor impact.

Lastly, the new dashboard will allow energy efficiency to feature more strongly in manager and team leader objectives – sustainability integrated into business performance!
