An icon of New Zealand industry exceeding its own expectations and leading by example in energy efficiency.
When ANZCO Foods reached its ambitious target of 36 gigawatt-hours in annual energy savings nearly two years ahead of schedule, it was clear their energy efficiency programme was making astounding headway and that they would need to raise the bar even higher.
Being energy efficient makes good business sense to ANZCO. The company has invested in a raft of energy efficiency projects that together form part of an energy management plan that has changed the way ANZCO operates.
DETA Consulting worked with ANZCO to set up energy-management committees at each of their nine sites and ANZCO invested $3.9 million in a capital works programme that included upgrading their hot water systems, improving refrigeration and rendering heat recovery and replacing old plant with state-of-the-art, energy efficient technology.
Progress is constantly monitored with adjustments being made to equipment and processes to keep energy efficiency at optimal levels. Savings are predicted to increase as there is a commitment within the energy management programme to make continuous improvements. So far, ANZCO has realised an outstanding 17% reduction in overall energy use, saved $2.6 million each year in fuel bills and can pass on some good, green news to their customers: greenhouse gas emissions per kilogram of meat are now down by 14%.
Showing how energy management can create a cost-effective and sustainable business plan.
Orora Beverage Cans’ plant at Wiri has had an energy efficiency make-over after a group-wide energy audit found it to be the site most in need of some fine tuning and new energy efficient technology.
The audit highlighted a list of ways in which the plant could save energy, so a team of engineers got to work installing new variable speed drive air compressors, undertaking air-leakage surveys and making necessary repairs, installing high-efficiency heating and lighting controls and putting insulation on heating water reticulation and washer tanks.
Since energy-management work started in 2013, Orora has seen electricity and gas use drop by around 30% along with a 30% reduction in greenhouse gas emissions and a 30% increase in productivity. Having smartened up the energy use at Wiri, the site now acts as a model of what can be achieved at other Orora sites and is an exemplar for other companies with similar industrial outfits on how energy efficiency can be used to improve productivity.
The recent installation of LED lights and optimisation of compressed air systems installed in 2015 now has the Wiri site on track to require only 15,500 kilowatt-hours of energy to produce a million cans – which is world-class efficiency.
A hub of energy savings, Auckland International Airport Limited maintains its position as a leading organisation in energy efficiency.
Auckland International Airport Limited (AIAL) keeps its greenhouse gas emissions in check with staggered targets that achieve quick wins, steady progress and aspirational goals. The new airport-wide monitoring system supports interim audits undertaken to ensure each energy efficiency project is on track and that investments in energy efficient technology are achieving or exceeding their payback in fuel and cost savings.
In the International Terminal Building, accumulated energy savings between 2012 and 2015 are over 9 million kilowatt-hours. This is in spite of the fact that passenger numbers have increased by 12% in that time and floor-space increased by 2% – as business grows, so it seems does the company’s energy efficiency.
The airport continues to benefit from the unwavering drive and determination of its Sustainability and Environmental Manager, Martin Fryer, whose leadership in energy efficiency was recognised in the 2014 EECA Awards.
A recent independent audit of AIAL’s energy management programme is setting the airport’s sights even higher and $4.3 million has already been committed to projects – including major plant upgrades – that extend to 2017 and are expected to see savings of 16 million kilowatt-hours per year once completed.
Engineering graduate reduces energy use by 10% for an already energy efficient company.
Having achieved considerable big-ticket energy savings back in 2006, Evonik knew that to reach the next level in energy efficiency they would need to take a more detailed look at their current technology and systems to find the less-obvious savings. Without the internal resources to do this, employing an engineering graduate was the perfect solution.
A fresh pair of eyes and recent training allowed Evonik’s new recruit to identify and develop new projects that would tidy up any leftover inefficiencies in energy use and revitalise the energy management programme.
Their graduate has generated several new initiatives including water cooling optimisation and hydrogen plant heat recovery. Planned projects will see the installation of energy efficient variable speed drives. A 10% drop in energy use has been achieved so far, which equates to savings of 10 gigawatt-hours per year and 2,200 tonnes per year of greenhouse gases.
Evonik now has an established relationship with Waikato University that sees their graduate engineer running tours of the plant for third-year engineering students. Year 13 high school students also visit the site to see a practical application of their studies.
Evonik has a mutually beneficial energy management plan that’s good for business and the environment, and is growing an industry of energy management professionals.
A successful energy management plan that is owned and operated by students.
Trident High School in Whakatane has reduced their energy use by nearly 16% over the last three years. Their 2013–18 energy management plan demonstrates what students and teachers can achieve by changing their behaviour towards energy use, alongside installing energy efficient and solar technology in a drive to be a more sustainable and self-sufficient school.
The project, led by teacher Dave Dobbin and energy advisors Sustainability Options, has made the importance of energy efficiency visible to students and demonstrates how a collective carbon footprint can be reduced when individuals are mindful about their energy use.
Aspects of the plan include energy-efficient lighting in the gym and auditorium along with a schedule that uses heating resourcefully: east-facing classrooms are heated differently from south-facing ones to take advantage of the natural warmth offered by the sun, and heating is switched off completely in classrooms that are not being used. Students learn how energy efficient technologies work and undertake monitoring and analysis of energy data in their maths and science classes. Some of the metal technology students have even developed their own renewable energy systems that are fully operational at the school.
Students are having the opportunity to be part of something that could help them be conscientious energy users in the future and it is testament to the success of the project that everyone has been able to contribute to the plan that is both relevant to the curriculum and applicable to real life.
The school already has 18 of the 25 action areas in their plan either completed or underway. The goal is to lower the school’s overall energy use by 40%, an admirable target which is currently within their reach.
At the Energy Management Association of New Zealand (EMANZ) we believe Energy Management encompasses a wide range of activities and expertise in the optimal use of energy.
Our membership includes energy consultants, energy managers in the private and public sectors, engineers, energy auditors, equipment suppliers and energy technology specialists.
