Making solar part of your business’s energy mix has never been more appealing. But risk and opportunity balances between an optimised design and types of PPAs.
While there’s heat in the market, there are incentives – but don’t unthinkingly sign away your business for a free set of steak knives! Or solar panels, for that matter.
According to the Electricity Authority, New Zealand’s solar energy generation capacity increased to just under 115MW in 2019.
Putting this into perspective, 115MW of installed capacity is similar to one of Contact or Mercury’s Geothermal stations. As a percentage, this equates to around 1.2% of total operating generation capacity in New Zealand.

Lowering costs for installed solar
The installed cost of solar has dropped by around 75% since 2009 to an average of around $2.20 per watt. With large commercial energy rates continuing to rise, the return on investment starts to become more realistic for business customers considering solar.
Location is more important than just sunshine hours and roof direction
With 29 distribution networks in NZ, there are a variety of charging structures for time of use electricity customers. Some networks prefer to charge more for demand and capacity than on the total volume of energy consumed. Understanding how these charges are calculated is an important consideration for the ROI of solar. For example, a network price structure that favours variable charges will potentially have a far greater ROI than a price structure that favours peak demand.
Depending on the distribution network, peak demand charges can equate to a significant portion of your total electricity costs. Installing solar alone does not necessarily impact peak demands to any large degree. However as battery storage becomes more economic, this will assist customers smooth their load and reduce demand based charges.
For no money down, you too could have a solar array. Just be sure to check the fine print. And pick up your steak knives!
Power Purchase Agreements are a great way for solar companies to sell solar arrays to customers as they don’t require a customer to come up with the CAPEX costs associated with the array. There are typically two forms of PPA’s that are common in NZ.
One involves the solar company installing a meter on the array that is installed and then billing you for the energy you consume from the array at an agreed price. You can still engage with the market and import energy from a standard retailer as required. An agreement would need to be struck with your retailer for any exported energy, depending on the solar PPA, the solar company may get all the financial benefit from exported energy.
The other type is where the solar company becomes your retailer as well and manages both the import and export of power.
Sometimes the solar arrays are oversized so that the solar company can charge you for what you consume from the array and then make money selling additional energy back to the market.
This can all be used to pay off the cost of the array and there can be lease to own options or buy-out clauses after a minimum term.
In both cases, there are minimum terms from anywhere between 7 to over 20 years. Where the length of contract, maintenance and replacement clauses become important as inverters can need replacing after 10-15 years and panels at 20-25 years.
Is Solar right for my enterprise?
The first question I would be asking is:
What is the comparison between owning the array outright and the associated financing costs with benefits from the array going directly to OPEX costs from day 1 versus the costs and risks associated with a power purchase agreement?
Total Utilities has recently completed three large scale viability studies of 42kW, 96kW, 146kW, 286kW and 350kW solar arrays for commercial facilities and can assist you in determining the best solution that meets your specific requirements.
Solar companies are often constrained by the supplier of their solar products for what and how they deliver an array. Getting an independent solar viability review by Total Utilities can increase the efficiency and output of an array to ensure full value for money if you make solar part of your energy mix.
Your corporate sustainability targets might be in for a shock!
Prior to Christmas, the Government announced a raft of proposed changes to the emissions trading scheme (ETS) to rapidly decarbonise the economy.
This included lifting the ETS price cap from $25/tonne to $50/tonne and creating a market floor of $20/tonne.
If we take natural gas as an example, where at $25/tonne the ETS is priced at $1.37, at the market cap of $50/tonne this would increase the cost of the ETS to end users by $1.37/GJ (0.49c/kWh). With current raw gas pricing hovering around $9/GJ for large industrial users this could make raw gas plus ETS $11.74/GJ (4.23c/kWh).
We spend a lot of time looking at commercial electricity and energy management and that’s really something to notice! If your corporate sustainability journey does not include electricity or energy efficiency milestones, now is the time.
In addition to this, a ban on new coal-fired boilers for low and medium temperature heating has been mooted. With all coal boilers used for low temperature activities to be phased out by 2030. Coal boilers would still be allowed for high temperatures of above 300 degrees celsius.
The Interim Climate Commission estimates that switching coal boilers away to electricity or biomass at scale becomes economic when ETS costs are in the range of $60-$120/tonne.
Now more than ever businesses need to start planning their sustainability journey. At Total Utilities we are here to help.

With environmental and economic sustainability at the heart of the corporate agenda, organizations face a range of risks if they fail to make progress
All organizations must pay close attention to risk. From financial viability to cyber attacks, it’s vital to understand and prepare for the forces that can disrupt the market and derail long-term sustainability – so businesses can survive in a fast-changing world.
Of all the risks that could affect a business’s long-term future, climate change is becoming one of the most urgent and complex. The United Nations warns that changing climate is disrupting national economies – and that accelerated action is needed to reduce emissions.
I want to hear about how we are going to stop the increase in emissions by 2020, and dramatically reduce emissions to reach net-zero emissions by mid-century
António Guterres, United Nations Secretary-General
Many organizations are already exploring what they can do to make a difference. They know that significant organizational, reputational and financial benefits can be gained by improving their environmental credentials. That said, our Distributed Energy Future Trends report found most businesses are investing in initiatives that we’d consider to be ‘low-hanging fruit’. Few organizations are implementing the most sophisticated technological innovations that could really accelerate their journey to net zero, such as smart energy management and on-site generation. In fact, just 18% of organizations see energy as an asset to be managed, in order to generate competitive advantage.
It’s important that organizations consider the strategic benefits of implementing the latest sustainable energy innovations. But perhaps even more importantly, they also need to recognize the risks they face if they don’t implement these innovations. Here are a few of the top concerns:
Energy security
As the world moves to low-carbon energy sources, making sure that you have continuity of supply is vital. Business leaders acknowledge the importance of energy resilience, which is why they rank energy security as being a top-three risk to their operations.
It’s important to have a detailed energy strategy, one that puts targets around energy resilience. Currently, only half of businesses that we’d consider to be ‘sustainable’ have an energy strategy that details how they will become a low-carbon organization. With other businesses, the figure falls to just 24%. Clearly, there is scope for businesses to push ahead in this area.
Having a plan is just the first step, though. It’s also important to consider implementing sustainable energy innovations, which can help to reduce reliance on the grid and provide additional security in the event of a power failure. Without harnessing the latest innovations, organizations may not be safeguarding themselves as fully as they could against the catastrophic consequences of power loss.
Innovation is good for business
In today’s economy, no company can afford to stand still. It’s important to keep moving forward and improve the products and services you deliver to your customers. Continuous innovation is good for business and often creates new opportunities that can enhance the way your business operates.
This is certainly true of sustainable energy innovations. From artificial intelligence to digitalized energy management solutions – low-carbon technologies can create new opportunities for businesses to monetize their power assets and improve their brand reputation. What’s more, organizations that look at their strategy anew and consider how they can join their energy technologies together can maximize their commercial benefits and return on investment. It’s clear that organizations who embrace sustainable energy innovations can gain competitive advantage – and those businesses that fail to harness these new opportunities risk being left behind.
Preparing for a more digital world
Organizations that aggressively pursue digitalization are expected to grow the most in the next five years. But companies that are truly future-focused don’t just introduce new digital platforms and technologies on a whim – they consider their wider implications, including the energy requirements of each digitalization initiative.
In our transformed world, new strategies are required to understand precisely where, how and when energy is being used across your organization. By monitoring, managing and aggregating all available energy assets, including energy demand and usage, organizations can ensure they generate and consume power in the most efficient way.
The latest sustainable energy innovations can support this initiative by providing organizations with the insight they need to make more intelligent decisions about their energy strategy in a digital world. But organizations that don’t embrace these innovations may lack these insights and could run the risk of wasting energy and money. And this may snowball, as more and more digital technologies are embraced.
Futureproofing your operations
Businesses that clearly define their energy strategy and invest in the latest sustainable energy innovations will find themselves in the best position to meet their environmental targets, gain competitive advantage, and futureproof their operations. Companies that do not embrace the latest energy technologies may find themselves at a disadvantage in a competitive market.
With businesses maturing at different paces, it will take strategic planning to accelerate environmental and sustainability ambitions. Contact Total Utilities to see how we can help you invest in sustainable energy innovations that will solve business challenges and deliver tangible results.
Our national grid pricing needs solutions. And after 10 years of pondering its navel, the Electricity Authority (EA), the Government agency charged with ensuring an efficient and effective electricity industry, plans to release a paper that may or may not gain industry consensus and may or may not actually be the right answer.
A decade in, the EA claims it is past the point where it is seeking an industry consensus, and advises that “you’ll have to show a factual error in our assumptions to change our views.”
This paper attempts to address the question, who pays how much for the right to access the electricity transmission backbone that is the national grid.
Just how we derive economic efficiency by perpetuating monopolies, stifling innovation and transferring the costs of transmission to regional small businesses and consumers, is beyond me.
This backbone is owned and operated by a Government-owned monopoly called Transpower, and connects our generation assets to the whole country.
The trouble with essential monopolies like the national grid is that they exert enormous political influence. Combine this influence with that of other essential monopolies such as the electricity generators who own our hydro dams, and massive energy consumers like the Bluff aluminium smelter, and the EA’s findings are wholly predictable.
This draft report, citing “economic value created”, suggests transmission costs be moved away from certain major users – notably the Bluff aluminium smelter – and should instead fall most heavily on domestic consumers and small businesses farthest from the point of generation. Meanwhile the hydro dam owners (the generators) will continue to utilise the transmission network without paying anything like the true cost of doing so.
When justifying their recommendations, the gurus at the Electricity Authority have estimated net economic benefits to all parties involved in the electricity market, of between $200 million and $6.4 billion by 2049. There are clear signs of an agency that has lost track of the most basic financial disciplines, when they can seriously suggest that a business case benefit that has an estimated range of $6.2 billion over 30 long years is somehow rational rather than looking suspiciously like a complete guess.
Virtually all these barely-credible benefits are assumed to come via increases in market efficiency. Just how we derive economic efficiency by perpetuating monopolies, stifling innovation and transferring the costs of transmission to regional small businesses and consumers, is beyond me.
Disincentives to use the national grid
The EA’s proposed pricing mechanism builds in disincentives for those seeking to find alternative methods of transmitting, storing and using electricity. The EA will do this in the following two ways:
By offering special discounts to people considering using innovations such as battery and solar to avoid using the grid. These discounts will be funded by transferring these costs to other consumers (in other words, not by reducing Transpower’s profits); and
By reducing peak load pricing. This is the mechanism whereby we pay more for electricity transmission at times when the grid is most heavily used: think winter cold snaps and dinner time. Peak load pricing offers a price incentive to those who want to store and use their own electricity at a time when it is most expensive on the national grid. No peak load pricing, no incentive to innovate.
The national grid was bought and paid for over decades by all the taxpayers of New Zealand. This asset was designed to reliably transport one of our most essential services, electricity, and to share the costs evenly to the benefit of all.
Perhaps the Electricity Authority should be paying more attention to mechanisms and policies that have seen electricity prices soar over the past two decades, instead of continuing this futile, decade-long attempt to fix a transmission pricing problem that didn’t exist in the first place.
New Zealand has set a target under the Paris Agreement to reduce its greenhouse gas emissions by 30% below 2005 levels by 2030, and to adopt increasingly more ambitious targets in the future.
Per capita, New Zealand’s emissions are one of the highest in the world with an output of <1% of the total world’s emissions.
Business New Zealand recently released a report which concluded that “opportunities to improve our performance in productivity and renewable penetration lie in every part of the energy supply chain. While productivity and renewables are not necessarily mutually exclusive, we need to consider the best policy balance. Our country is richly endowed with resources so should our focus be primarily on economic growth with a reliance on carbon prices to guide renewable penetration, or do we need stronger policy support for low-carbon economic output? With an economy heavily driven by trade, the cost of our choices has direct consequences for our international competitiveness. And, since our future is uncertain, how do we remain responsive and resilient to changes in the world around us?”
There is no doubt that the current Government’s policy strategy is being geared to meet the targets under the Paris Climate Accord.
The Insights Behind Sustainable Business Growth
Centrica recently published the following survey of businesses in 10 countries (UK, Ireland, Germany, Italy, France, Hungary, Belgium, Netherlands, USA and Mexico) and across 7 verticals (manufacturing, retail/ wholesale trade, healthcare/ medical, education/schools/universities, construction/ trades/ property development, travel/tourism/hospitality and property/real estate).
The survey identified some interesting trends:
Customers are driving change
Perceived risks are growing
Energy is an increasingly vital part of an overall business strategy
Yet only 1 in 8 businesses are doing it successfully
They concluded that in today’s fast-changing world, businesses need to find an innovative way to balance their financial performance and environmental policies using the following key focus areas.
What does this mean for your business?
Becoming a supportable business isn’t something that can be achieved overnight, and the journey can be challenging. Many successful businesses are complementing their internal expertise by engaging a third party, like Total Utilities, to help them understand the energy market and associated technologies, build business cases and engage stakeholders.
The Government has set a target for New Zealand’s economy to be net-zero emissions by 2050. Does our current approach stack up?
Methanex – adding 15% to national electricity demand?
In a recent submission to the Ministry of Business, Innovation and Employment (MBIE), Methanex, New Zealand’s largest single gas user suggested that should the company transition from gas-based manufacturing of methanol to electricity, this would increase New Zealand’s national electricity demand by around 15% (5,800 gigawatt-hours). In other words, there would be a Rio Tinto Aluminum Smelter-sized electricity user in Taranaki.
Methanex currently consumes around 88 petajoules of gas and 84 gigawatt-hours of electricity and produces about 2.4 million tonnes of methanol per year.
Located away from New Zealand’s main generation sources, this would place increasing pressure on the North Island generation mix. With only limited new baseload generation planned for the North Island, electrification of methanol production would require more coal and or gas being used by thermal generators.
Methanex says that should conditions become nonviable to remain in New Zealand, they would relocate to China. Because of China’s current generation mix and energy sources, this could increase global emissions by four to six million tonnes of carbon dioxide a year.
The hydrogen solution
Last year the New Zealand Government signed a memorandum of understanding with Japan to develop hydrogen production in the Taranaki region with the view to pave the way for a transition away from Natural Gas and LPG.
However electronic hydrogen production will further strain the New Zealand energy system as 41.4 kWh of electricity is required to produce 1 kg of hydrogen from water.
In a recent article, Centrica (owner of British Gas) warned a move to make the gas grid run on hydrogen is “unlikely to be practical”.
Centrica chief executive Iain Conn said natural gas would be “crucial” in the transition to reducing carbon emissions, and that Britain and other countries would need to start using more of it before it could wean off the fossil fuel.
“It is quite clear that we cannot get from A to B without using more natural gas,” he said at a speech at the Aurora Spring Forum in Oxford.
“I don’t believe in the mass use of pure hydrogen, I think it highly unlikely to be practical,”
Iain Conn
Conn said, but said he was open to injecting around nine per cent hydrogen into the grid.
“We have done a lot of decarbonising power generation, but heating and cooling will be key,” he added.
Heating and Cooling in Britain
The remarks come just a week after chancellor Philip Hammond announced a plan to ban fossil fuel boilers from new homes built after 2025.
“We will introduce a future homes’ standard mandating the end of fossil fuel heating systems in all new houses from 2025, delivering lower carbon and lower fuel bills too,” Hammond told parliament during last week’s Spring Statement.
Conn said that heat pumps would eventually start taking British homes off the gas grid. He also said the world would be able to add around one gigawatt of renewable power capacity each day for the next 30 years.
Heating and cooling in New Zealand
Heat pumps in New Zealand have only added to electricity demand in recent years as more are installed and being used for cooling in Summer as well as heating in Winter. While more efficient than electric fan heaters, gas heaters and oil column heaters, the added cooling load has counteracted the savings in many cases as large numbers of New Zealand homes are moved away from wood burners.
These concerns were echoed in New Zealand by Paul Goodeve, First Gas Chief Executive, saying that, “A key element is affordability. We need to find affordable ways to meet winter electricity peak demand and maintain the competitiveness of large industries that use gas for production. Would New Zealanders find it palatable to pay substantially more for their electricity to upgrade infrastructure which will be underutilised to cover large energy use sectors and peak winter use? These are considerations we believe policymakers need to take carefully into account when making decisions.”
