WineWorks
Challenge
WineWorks have set a goal of improving sustainability, however to improve operational performance and reduce scope 2 emissions the team need to gain timely visibility of electricity, LPG and water consumption at their Malborough plant.
Solution
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, compresed air, nitrogen and after hours usage. Detailed monitoring identified how production usage and other factors impacted energy use, allowing accurate businesses cases to be developed.
Outcome
A clear plan of improvement was established to deliver initial savings. In the first 12 months lighting was replaced and a preventative maintenance plan to regularly check and fix air leaks was put in place. Monitoring has also provided the information needed to demonstrate to staff the benefits of improved shutdown procedures and the ability to continuously monitor impact. In the first year savings of 5% were achieved with a further 15% to 20% planned in the near future with upgrades to the nitrogen system and air compressors. The site is also looking forward to the new dashboard, with energy efficiency featuring more strongly in manager and team leader objectives…sustainability integrated into business performance!

Mobil Oil
Challenge
Mobil were looking for a way to reduce energy usage at 118 fuel stations across New Zealand. ESP benchmarked the sites according to type and provided a cost-effective solution for a monitoring and targeting programme.
Solution
A combination of retail and sub-load metering was installed at 20 fuel stations across the country. These sites were the most energy intensive. ESP carried out site reviews and set up frequent steering group meetings to review, track, and implement the actions that were recommended.
Outcome
The project has resulted in energy reduction of $440,000 since September 2017. ESP continue to monitor the sites as well as discuss new recommendations with Mobil to continue their energy efficiency journey.

Webstar
Challenge
The print industry is known for its tight margins. Webstar has utilised ISO as a framework to continuously measure, plan and improve for some time now. Energy, as one of manufacturings largest costs became a target for applying this process to ensure the business could measurable improve and sustain energy efficiency gains.
Solution
Webstar found ESP from the EECA website and soon identified the data-driven approach fitted well with their desired approach. ESP identified a range of quick wins and then looked to detailed monitoring of key plant to sustain those gains, and identify more.
Outcome
Results have beaten expectations, with 5.7% reduction within the first year and now cumulative savings of over $250,000 resulting. On top of this, production costs have reduced by an estimated $500,000.

Auckland Council
Challenge
Managing 3,500 properties with a wide range of uses, distributed around Auckland with a small team is a huge challenge for Auckland Council. However with energy efficiency targets to meet the Council team needed to focus on achieving and sustaining gains through partnership.
Solution
The ESP energy and water monitoring solution was implemented at nearly 100 of the Councils largest, or most used buildings. The team is able to remotely identify and target improvements in the portfolio and be alerted when anomalous usage occurs. The system is now a core component of delivering to the corporate property portfolios emission reduction targets of 50% reduction by 2030 and net zero by 2050 from the Councils FY2018 baseline.
Outcome
The council have achieved energy savings of 11.73GWh (the amount ~1,035 households use each year), avoided 1,231 tonnes of CO2-e and are on track to save $1.5m per year in operating costs. Throughout Covid-19 the team was able to monitor key sites remotely, ensuring they were efficiently shutdown whilst still ensuring appropriate ventilation for their use.
Auckland Council has also invested in the use of View, providing up-to-date and digestible data on the business’s progress so far in sustainability.
