We are delighted to announce that as of February 2021 we are Toitū carbonzero certified. This means our commitment to taking positive action on climate change has been officially recognised.
We walk the sustainability talk by managing and reducing our greenhouse gas emissions, wherever we can, and neutralising our unavoidable emissions.
Who is Toitū and what is Toitū Envirocare Carbonzero?
Enviro-Mark Solutions is now Toitū Envirocare. Toitū means “to sustain continually”. It asks us to work together continuously to care for our planet, people and communities. Toitū connects actions with outcomes and asks us to hold fast to the land, to our pride and to all living things.
Toitū carbonzero certifications “meet and exceed the requirements of ISO standards and ensure consistent and comprehensive reporting, benchmarking and management under international best practice”.
Total Utilities’ Carbonzero facts and targets
Our company emissions are quite small at 20.57 tCO2e, but we know we can do better.
That’s why we have set an ambitious, yet achievable, annual target of reducing our baseline emissions of 10% per year over the next three (financial) years.
Most of our emissions come from land transport – 80% is petrol and diesel use – and the remaining is domestic air travel and electricity (see graph below). The obvious next step is to be smarter around our travel choices, yet still deliver excellent service and competitive pricing.
Total Utilities’ Carbon Reduction Goals
Total Utilities will do the following to reduce our emissions.
Prioritising online meetings over travelling to meetings – where possible and practical.
Grouping client visits where possible if travelling a distance, this includes national travel and domestic flights.
Using recycled packaging and choosing courier services that have sustainability programmes in place.
Caring for people and the planet
Rather than buying carbon offsets, we have decided to support renewables-based projects that benefit at-risk communities. This means that along with contributing to renewable energy initiatives, we are also doing our bit to create jobs and improve the overall health and wellbeing of these communities.
We all benefit from sustainable action
We are thrilled that we can join a growing collective of hundreds of organisations who are leading the way to a low carbon future.
But it doesn’t stop there. At Total Utilities we have the skills and the experience to support more New Zealand businesses to measure, manage and reduce their carbon emissions and energy consumption. When you switch to renewable energy sources and manage your energy consumption, you not only reduce your transport and power bills, but you can limit your environmental impact too.
Our hope is that in being open about our sustainability targets and our progress, we will inspire you to make positive changes to the way you use and consume energy for a thriving Aotearoa.
New Zealand Aluminium Smelters has struck a new deal with Meridian Energy which means the smelter will remain open until at least Decemeber 2024. We don’t yet know the prices that Rio Tinto has agreed with Meridian, but Forsyth Barr estimates that Rio will be paying a contract price of 3.5c/kWh. Compare that with large energy users across the country, who are paying over 11c/kWh.
Last week, the news pushed already elevated ASX energy futures higher. Customers leaving contracts on or around a raw energy price of 8.5c/kWh struck 3 years ago are now facing, on average, raw contract pricing of 13-14c/kWh — an increase of 65% or more.
Is pricing sustainable for large users?
ASX Energy Futures climb higher and higher
In July 2020, when the market was expecting a full exit from Tiwai by the end of 2021, pricing fell significantly. South Island consumers were especially fortunate — Total Utilities helped customers negotiate raw energy pricing around 6c/kWh. North Island pricing also fell from around 12c/kWh to 9c/kWh.
New Zealand’s large commercial businesses are paying a premium for the smelters continued electricity supply in the current electricity market. And it’s not just electricity pricing that has increased, but gas too, with prices moving from around $5.50/GJ to over $9/GJ in the last three years.
Transmission pricing hasn’t changed. Yet. But it is almost certain that Tiwai will see transmission costs reduce, while the rest of the country is left to pick up the upgrade bill when Manapouri gets connected to the Clutha Upper Waitaki network.
Additional energy and gas costs cannot just be absorbed by consumers, particularly in the primary and food production/storage sectors where energy-intensive operations exist. The cost of living will continue to inflate, while income increases will struggle to keep up.
Overcapacity of generation must be built between now and 2030, while an increase in gas-fired peaking plants is needed to ensure a secure supply.
Future path requires significant investment in new wind and solar generation
In the current market, there is no incentive for an oversupply of energy production. Instead, due to basic supply and demand principles, constrained generation allows producers to make tremendous profits.
In large part, the Government has ignored the 2019 report and instead focused on the proposed pumped hydro scheme at Lake Onslow. This multi-billion-dollar project won’t be commissioned in the short-term and is located well away from high energy demand areas. The government would gain faster traction if they subsidised microgeneration and battery storage.
Gas production is still a major and immediate concern, with New Zealand’s largest gas more or less 35% down on expected volumes. Remedial work and new drilling projects are unlikely to start until early 2022, so it’ll be some time before gas supplies return to “normal” levels.
Generators have various projects to increase renewables-based generation. These will not likely come into service until after 2024, though. A lack of clear market strategy means timing and development have been poorly managed. The “just” transition to renewables is underway, but who exactly is it “just” for?
A window into the future
On 31st January, 2021 He Pou a Rangi/Climate Change Commission released a 2021 draft advice for consultation report. This report delivers more focused advice that the government would be wise to follow to stand a chance of reaching our country’s zero emissions target.
The energy prices that businesses are paying now is a result of uncertainty and not having enough renewables-based generation to meet dry year demand when gas supplies are constrained. This is not sustainable.
From page 81 of the report: “Future electricity prices are uncertain due to a range of factors, such as the weather, gas availability, future infrastructure requirements and pricing structures.”
The report clearly shows that we need more energy generation, that we should accelerate and incentivise the move to electric vehicles, that we need to make the transition affordable and attractive to businesses and families, and that natural gas plays a role in helping us get there. And it asks if we should do what we can to retain and retrain the incredible talent that exists in the natural gas sector instead of losing them to offshore contracts.
Building more wind and solar generators is money and time well spent, as this will increase energy supply, and translate to lower energy prices. That’s why new renewables-based generation needs to be built and fast, otherwise energy pricing will only remain high and increase further as we decarbonise the economy.
As page 112 of the report so clearly puts it, “For consumers and industry to invest and convert to electrification, they need to have confidence that electricity will be available, affordable and reliable.”
What can you do?
The harsh reality is that the cost of energy is going up. Without significant new generation being commissioned and the ongoing gas supply issues, costs are unlikely to fall again in the next four years.
That’s why we recommend you review your pricing and go to market early, as prices are front end loaded. You could potentially get a better price well in advance of your contract end date and lock it in. Alternatively, having a second round is always an option closer to contract-end.
We’ve given a considered view of where pricing is heading in this blog, but it could be conservative. In any case, budget for a serious increase in costs.
If you want to mitigate rising costs, the best thing you can do is reduce the amount of energy you consume from the grid. You can achieve this by understanding what you consume and optimising your consumption and generating your energy onsite (through solar panels or similar renewable sources).
With increased energy pricing on the cards, now’s the time that you get significantly more bang for your buck when you invest in energy and carbon reduction projects. That’s why the team at Total Utilities are here to help you achieve energy efficiencies and, when you’re ready, guide you through the switch to solar and other renewable sources.
Back in the 1950’s when I was born, the global population was 2.75 billion and it had taken roughly 2 million years to reach this figure. During my lifetime, the world’s population has nearly tripled to 7.5 billion.
This population explosion has helped to ruin pristine wilderness areas from the Amazon rain forest to Africa and Asia and triggered growing competition for resources, including water, to sustain our ever-growing numbers!
Human beings and the animals we eat now dominate the planet’s landscape to an unprecedented degree.
NZ may only have five million people, but we are not immune to environmental degradation. Our environment has also suffered from air and water pollution, not to mention the introduction of invasive species since our country was first settled.
As with the rest of the world, we have been hard hit by the Covid-19 pandemic.
So far, our Government has done a good job in my view in handling the health aspects of the crisis.
The economy though has already been bashed in 2020 and whoever wins the forthcoming General Election is going to be faced by the worst economic pandemic since the Great Depression of the early 1930’s.
This will pose a massive challenge to us all.
In the long haul, climate change is the more important issue.
In the shorter term though, common-sense dictates that all Governments internationally need to focus on avoiding any repetition of the massive long-term unemployment of the 1930’s which triggered the ‘beggar my neighbour’ economic policies followed by many Governments and hence helped pave the way for the Second World War.
So, what does this mean for sustainability issues?
Should they be put on the back burner for the next few years while we focus on the economy or should we continue to press ahead and take action?
When all is said and done, sustainability should be about protecting the environment both nationally and globally.
Ultimately, we will sink or swim together on this planet of ours. As such, the environment includes the air we breathe and the water we drink. That includes the rivers, lakes, seas, oceans and forests that we take for granted.
Like most of you, I have enjoyed watching David Attenborough’s wildlife documentaries. In my case since the early 1960’s. His documentaries have done more to publicise the growing plight of wildlife and the natural environment as a whole, than anyone else.

Sadly, they tell an increasingly gloomy tale of habitat destruction, pollution and species extinctions.
So, what does this mean for NZ? What should our Government do to reverse the tide of environmental degradation. Available options include:
Manufactured goods – where humanly possible they should be made from 100% renewable materials.
Packaging – suppliers (not customers) should be made 100% responsible for disposing of packaging material, including polystyrene!
Glass bottles – reintroduce refundable bottle deposits on all glass bottles nationally and replace plastic bottles with glass bottles.
Plastics – waste recyclers to have uniform standards nationally regarding what plastics are recycled and what go to landfill. If some types of plastic can’t be recycled in NZ, their use should either be banned outright or a new national facility should be set up to process them. There are currently big regional differences regarding what plastics can and can’t be recycled.
Coal vs natural gas – given that the rate of carbon emissions associated with coal is nearly twice as high as they are for natural gas, recognition should be given (as it is internationally) of the important role that natural gas/LPG will play for the next 20 years as a transition energy source on the road to 100% renewability and carbon zero.
Transportation – the idealogues on the ‘left’ and the ‘right’ of politics are both right and wrong when it comes to transport policy. The left is correct in believing that we need much better integrated public transport networks (road/light rail/car parking) in the main centres. The right is correct that whether we like it or not, Kiwis like the freedom that comes from having your own vehicle. Hence, we need to sort out and future proof the road network in the major centres and also upgrade the roads in long neglected areas like the Far North. Clearly it makes good sense to transition to electric vehicles, especially given that the carbon emissions from petrol and diesel vehicles are far higher that carbon emissions from electricity generation.
Local manufacture vs imports – again within reasonable bounds, I am a strong believer inbuying NZ manufactured goods versus importing from the usual source. By doing this, we are using suppliers who are likely to have a greater environmental conscience. Also, the carbon footprint associated with shipping the goods to NZ is avoided. We also provide work for our fellow citizens and keep their income circulating in our local economy. Similar arguments apply to our choice of holiday destination, even when Covid-19 international travel restrictions are finally lifted!
Housing – make it mandatory for all new houses nationally to have both solar power units and water tanks installed from day one. Also, the All of Government (AOG) procurement process could be utilised to encourage local manufacture in both areas and financing options for both.
We are facing unprecedented challenges on a number of fronts and our Government needs to act accordingly in a politically bi-partisan way!
The deployment of grid‐connected photovoltaic (solar PV) systems continues to grow at an impressive rate. In 2018, there was a 30% increase in systems implemented and it continues to move forward.
Most of this growth involves residential systems, which have an 80% share of the connected capacity in NZ.
Where’s the growth in commercial solar pv systems? Why are the industrial and commercial sectors lagging behind?
The following article was written by Perry Hutchinson, who holds a Master of Engineering Studies in Renewable Energy Systems and has 30+ years of experience designing and implementing industrial electrical systems.
One benefit drives decisions about solar PV for industrial/commercial use…
Commercial Solar Power System Cost
The New Zealand Smart Grid Forum identified that although residential consumers consider a range of potential benefits ‐ such as energy independence, environmental impact and a desire to participate in the technology ‐ sound economics is what drives industrial and commercial consumers.
So the challenge in photovoltaic design is to present solar as a viable business investment in New Zealand, even though we lack the government subsidies and generous feed‐in tariffs enjoyed in many other countries.
What is a feed‐in tariff?
Feed‐in tariffs (FIT) offer you a defined payment for the energy you feed into the grid from your solar PV system. In New Zealand, this can be as low as $0.04/kWh.
When generous feed‐in tariffs are available, the key constraint to system size is essentially the available space for the PV array; for viable projects, the bigger you build it, the greater the return.
However, having low feed‐in tariffs changes the whole approach to system design. There is a tipping point where increased size (and increased investment) actually results in diminishing returns.
Forget feed‐in tariffs. Focus on offsetting electricity costs
The viability of a PV system (photovoltaic system) with low feed‐in tariffs depends on offsetting electricity cost. And offsetting electricity cost depends on discovering the optimal level of self‐consumption.
There is a tipping point for self‐consumption with on‐grid PV systems. This is the maximum size of the system where we still achieve 100% self‐consumption. Building the system larger than this results in some of the PV generation being fed back to the grid and therefore, self‐consumption starts to fall.
Generation Profile for commercial solar power systems
But with the generation profile changing ‐ not only seasonally, but also daily and hourly ‐ what is this optimal level of self‐consumption? A system size maximised for 100% self‐ consumption in summer will fall short of that in winter. Conversely, a system size maximised for winter will over‐generate in the summer (and lower self‐consumption as surplus is fed back to the grid).
Load Profile for commercial solar power systems
In addition to this, load profile must also be considered. What if the load is biased towards the morning or biased towards the afternoon? This could impact the optimal direction you orient the array (the azimuth). For example, a more westerly orientation may be better for load profiles with an afternoon bias.
Tariff Structures for commercial solar power systems
Tariff structures could have a similar effect. We have worked with clients with quite complex tariff structures that could influence array configuration. For example, high morning tariffs could mean a more easterly orientation is better.
Obviously, each situation is unique and requires something more than an “out of the box” solution due to the complex interplay between these constantly changing variables – the solar resource, load profile and tariff structure.
Our approach to getting Solar Power right
Traditionally, a project’s net present value (NPV) is used to evaluate and prioritise projects. NPV takes into account the time value of net cashflows over the life of a project by applying a discount rate.
But rather than treating this as an “endpoint” calculation, at Pacific Energy we use NPV to optimise the PV design.
We model a system on an hourly basis over a year using NIWA weather data, the tariff structure and load profile from the time‐of‐use meter as the key inputs. The model then finds the optimal combination of size, tilt and azimuth that maximises the NPV of the project over its 25‐year life.
The maximised NPV reflects the optimal level of self‐consumption for the system which in our experience can be anywhere between 85 – 95% on an annual basis. This provides the starting point for more detailed design to be undertaken.
For solar projects, Total Utilities partners with Pacific Energy whose focus is on bringing sustainable energy projects to life.
By combining sharp economic analysis with a deep understanding of industrial power systems, they design and specify viable and pragmatic solutions that optimise energy use and reduce carbon footprint. They are experts in system analysis and provide unbiased, independent advice for investment decisions.

Covid-19 Confessions
What has occurred to me is just how anxious so many of us have become during Covid-19 lockdown. Simple things like supermarket shopping and big things like keeping business and personal finances on track have all become causes for concern.
A friend admitted to reading his young son’s online homework recently. It was a short essay on life in a bubble. “Dad is getting cross a lot” and “Mum’s acting weird sometimes” leapt off the page. He is a good, kind man and has a loving family. Trouble is, he is no more immune to the stress of this lockdown than any of us.
My beloved and I shared some tears on Saturday. We haven’t seen our adult kids or grandchildren in the flesh for a month! We are a touchy-feely family and the lack of their warm embraces has left us feeling empty.
My experience with anxiety last year does not give me any great right to speak into your lives. I can but share my insights and hope that you gain something from them.
Living in a bubble and yet finding joy
Using tools helps
The “cure” for my high levels of anxiety last year was a combination of admitting to myself and those close to me that I was struggling and acquiring some practical coping skills.
Learning some mindfulness skills and breathing exercises gave me something to fall back on when I found myself chewing on issues or repeatedly waking up in the night and unable to get back to sleep.
www.headspace.com is just one of several applications available that offer training and reminders on how and when to relax and be present in the moment.
A walk each day is an easy answer and yet hard to do when the funk descends. The good news for me is that the dog won’t say no until she gets her daily exercise.
Replace empty chat with real conversations
I have found out so much about my beloved in these last days and she about me. I won’t share the detail but fair to say that she is even more exciting and amazing and wonderful than I already knew.
Zoom can’t replace a hug
My colleague Richard is old school. I, on the other hand, come from the hippy school of peace and love. With that comes uncomfortable (for Richard) embraces when I call into the office and insist on a hug.
We meet every morning for half an hour using Teams and it is great to hear from him, but I do miss making him hug me. Hug the ones you love. It might be just what they need that day.
Meet friends and colleagues regularly
We have an online meal with friends or family several times a week now. It is breakfast with our daughter in Berlin or coffee after Church with a couple who share our spiritual journey. It is a candlelit dinner over a Cote du Rhone with our travel buddies. Tomorrow Euan from work is hosting an online quiz using a cool tool called Kahoot! All these give us connection, a laugh or two and with luck a chance to relax a little.
Forgive and Forget
Can you trust yourself to be completely perfect in every way while locked in a cage not of your own making?
If it’s you who has been a of bit of a plonker then find a way to apologise. If you been offered an apology, then accept it. Love and relationships are a two-way street.
Try Something New
Every day on lock down is time you can innovate, refresh, or learn new things. In professional services we often think about “billable hours” and when they slow down a certain panic sets in. Using “free hours” when there is time available is the source of efficiency, innovation and great product development. Use the time in lockdown wisely – you won’t get it back.
Are You Okay?
I wrote this blog so you can know that you can not only get through this time but can be better and stronger for the experience.
Look around yourself and see the blessings. Take that breath of unpolluted air, listen to the birds and enjoy the company you have.
Above all though ask yourself and those you love “Are you okay?” It may be the most important question you ever ask. The answer may well bless you for the rest of your life.
Improve manufacturing operations and cut costs by setting operational efficiency KPIs.
In the last 3 months the global economy has been turned on it’s head due to the Covid-19 pandemic. In light of this, manufacturers are faced with the pressures of producing more high-quality goods, with less money, time and resources. Regulations are becoming more stringent and competition is growing in a smaller market.
To achieve the goals of lean operation, industrial manufacturers need to constantly monitor, benchmark and improve.
KPIs can prove a valuable gauge of progress, helping manufacturers to set and achieve their business goals and maintain critical business resiliency.
1. Optimise maintenance schedules
Many manufacturers still operate preventative maintenance schedules. Preventative maintenance is costly because only 15% to 20% of all components fail after a predictable time. Reducing operational costs means approaching maintenance in a new way.
A predictive maintenance program – servicing machines based on need-based early stage notifications – is much more efficient than a Fixed Time Maintenance (FTM) Preventative Program.
This allows manufacturers to be proactive, rather than reactive when it comes to equipment repairs and operational downtime. They can make informed decisions, based on transparency and a pattern that is most suitable to their business.
Reduced costs and eliminated outages should be demonstrable when manufacturers transition to a predictive maintenance mode and track overall downtime.
2. Improve true downtime cost (TDC) and downtime percentage
Consider the true cost of unplanned downtime. Do you know what the cost of downtime is to your business? Decreasing downtime and improving operational efficiencies can save manufacturers millions of dollars.
By calculating your True Downtime Cost and showing measured improvements in this realm, you can illustrate saved time and money, as well as reduced waste and create a data-driven, quantifiable resiliency plan.
Understanding true costs can also help you to make cost justification within day-to-day management decisions.
3. Improve Rolled Throughput Yield (RTY)
RTY is the probability that a single unit can pass through a series of process steps free of defects. Acceptable Rolled Throughput Yield is dependent upon a very high individual first time yield for each process. It is the sum of the parts measurement that is most critical to overall operational efficiency.
RTY is a great operational efficiency KPI to track as it alerts manufacturers to the health of their entire operation, rolling all processes into a single measurement.
4. Maximizing capacity utilisation
Diminish the cost of owning and maintaining equipment by using equipment to its full capacity.
By measuring the output that is actually produced and comparing it to its potential maximum output, manufacturers can understand the efficiency of their operation. Increasing capacity utilisation increases overall efficiency.
An OEE score presents “an accurate picture of how effectively your manufacturing process is running. And, it makes it easy to track improvements in that process over time.”
Conclusion
These Operational Efficiency KPIs will give you an indication of the overall efficiency of your operation and a real sense of your resiliency needs.
Any downward trends in performance will require deeper analysis. Manufacturers should also look at processes, systems, and the performance of equipment.
With improved visibility and intelligent use of smart technologies throughout the plant, manufacturers can take a leap forward when boosting operational efficiency throughout the business. Using real-time data allows you to plan, in a quantifiable way, the need for a backup plan.
