If 2024 taught us anything, it’s that unpredictability is the new norm. From gas shortages and hydro lake levels nearing rock bottom to record highs and lows in pricing, the year had it all.
One thing is clear: the current market structure isn’t serving commercial and industrial customers well. Short-term issues have impacted long-term pricing, forcing customers to pay a premium for future energy, even when conditions might improve.
In a previous article, I delved deeper into how coal sets the overall price in a largely renewable energy grid. You can read more about it here.
Looking Ahead to 2025
As we step into 2025, hydro storage levels are at 85% capacity, which is 22% higher than usual for this time of year. Wholesale electricity spot pricing remains low, with thermal generation contributing only about 3-5% to the grid. Current prices are around 4-5c/kWh, a significant drop from last January’s 25c/kWh. However, with limited natural gas availability and coal firming the market, price volatility is more pronounced, especially during dry periods when wind generation drops.

The ASX Energy Futures Market
Forward market pricing remains stubbornly high on the ASX Energy Futures market, which sets the overall forward price for retail contracts for large commercial and industrial customers. The current quarter (Jan-Mar 2025) is priced around 12c/kWh in the North Island and 7.4c/kWh in the South Island.
The ASX Energy Futures market is dominated by the big four generators: Contact, Genesis, Mercury, and Meridian. These generators offer volume into the market for participants, which can include other generators, retailers, major energy users, or investment houses.
Long-Term Pricing Trends
Over the past year, long-term pricing on the ASX has steadily increased as natural gas supplies dwindle. The market seems to be factoring in more risk as coal becomes the dominant fuel for managing limited hydro storage.
North Island pricing for 2026, 2027, and 2028 has risen by 19%, 26%, and 11% respectively since January last year. Similarly, South Island prices have increased by 28%, 35%, and 14%. Notably, pricing for 2028 only became available on the market from October 1st last year. The forward price curve has also shifted from a staggered reducing price to an almost flat price within any given year.

The Future of Firming Fuels
This trend suggests that coal will remain the firming fuel of choice for the foreseeable future, despite calls for liquid natural gas imports as a lower carbon emission option. The industry appears divided on future firming solutions, adding to the uncertainty.
As we navigate through 2025, staying informed and adaptable will be key to managing the ever-changing energy landscape.
Navigating the Future of Renewable Energy and Market Volatility
The announcement of new renewable generation projects is exciting, but it comes with its own set of challenges. Much of the new capacity is in solar and wind, both of which are intermittent and cannot be relied upon for firming. While battery storage is becoming more economically viable, it hasn’t reached the point where it can fully replace traditional firming methods. New hydro or geothermal developments, which could provide the necessary baseload generation to support intermittent sources, are facing lower priority due to high costs and resource consent issues.
What to Expect in the Coming Year
As we look ahead, the energy market is expected to remain volatile. Both Transpower and the Gas Industry Company have warned that natural gas production may fall below demand during the upcoming winter. This shortfall will likely keep energy prices unstable. Additionally, the commissioning of new generation projects is progressing slowly, meaning the reliance on fossil fuels for firming will continue in the short term.
Preparing for Contract Expiry in 2025
If your electricity contract is set to expire in 2025, it’s crucial to start planning early. Seeking market pricing well in advance of your contract’s expiry date allows you to set realistic budgets and mitigate the impact of short-term volatility.
Consider exploring solar options, whether on-site or off-site. Both approaches enable you to purchase solar energy as a commodity, reducing your exposure to price fluctuations in the broader energy market.

Changes to national grid operator Transpower’s transmission charges took effect in April – and as with most things in life, there are winners and losers.The updated transmission pricing methodology (known as TPM) significantly differs from previous years, and has delivered a mixed bag of rises and cuts for domestic and industrial users.
State owned enterprise, Transpower, has been allowed to recover $830 million by the Commerce Commission for running the network and the increased costs are now being passed on to end users.
Changes to charging methodology
Transpower Head of Grid Pricing Rebecca Osborne said the Electricity Authority has designed the new methodology to more closely reflect the costs and expected benefits of electricity transported across Transpower’s 12,000 kilometres of transmission lines.
There should be no surprises across the electricity industry about the new transmission charges, she said.
“We’ve consulted with customers along the way and provided information as the elements have developed, including updating our indicative prices… and providing indicative rates information in early November.”
“Total transmission revenue, as set by the Commerce Commission, remains the same, but how it is distributed among Transpower customers has changed.”
Encourage renewable generation
The Authority expects the new approach to transmission charges to encourage investment in renewable generation and electrification of industrial processes.
According to Transpower, the main change in the new transmission pricing is a move to a benefit-based approach where customers pay in proportion to the benefit they are expected to receive from some historic and all future transmission investments.
The previous methodology spread the cost of the HVDC (High Voltage Direct Current) link connecting the two main islands across South Island generators and spread the cost of all other interconnection assets across local lines companies and major industrial users.
Some Northland, East & West Coast customers hit hardest
In general, this means cost increases for local lines companies and some of the largest industrial customers in the north of the country because they are further away from where the bulk of generation is located in the South Island.
It also means North Island generators will begin contributing to the cost of the interconnected transmission assets and South Island generators will contribute less.
Consumers in Northland, the east coast of the North Island, and the West Coast have faced the biggest hikes, while Wellington and some South Island areas have seen prices fall.
The final amount that consumers pay for their transmission charges is ultimately decided by local lines companies, these charges typically make up between 8 and 10 percent of power bills.
Big power users such as the Tiwai Point aluminium smelter have seen an almost $10m price cut, while NZ Steel mill at Glenbrook faces an $11m increase.
Earlier in the year the Electricity Authority calculated movements would generally be small.
Those most affected may take issue with this. Indeed, Buller Electricity filed for a judicial review after being told its transmission charges would rise by 427 percent.
Total Utilities is New Zealand’s largest issuer of business-to-business energy procurement tenders, providing energy purchasing services to many household names. With around 500 tenders issued to the market every year, getting favourable terms is crucial. But negotiating energy contracts is so much more than getting a great price. It involves an understanding of the many moving parts.
The variables that influence retail energy prices are:
GEOGRAPHICAL
New Zealand’s population is dispersed over a large land area, creating its own set of challenges.
FINANCIAL
Prices are based on the changing supply and demand through the wholesale spot market.
MARKET-DRIVEN
The market is deregulated, and our national energy supply consists of generators/retailers, the national grid operator and 29 local distribution companies. Energy retailers can hedge future energy on the ASX Energy Futures market.
SOURCE OF ENERGY
New Zealand has a diverse generation fleet, including hydro, geothermal, wind, and coal.
REGULATORY
The Emissions Trading Scheme, Net Zero 2050 and shifting government policy influence generator behaviours.
TIMING
Changes to hydro storage and government policy mean windows of opportunity can be very limited in the energy market.
That’s why engaging independent energy consultants who understand the variables, the available options and when to time procurement events is so worthwhile.
Let’s look at different scenarios where our clients saved significant sums because they had Total Utilities on their side.
TIMING MATTERS Leaving a negotiation too late gives retailers an unfair advantage, as customers have limited options to choose from. A large university’s contract was due to expire, and they were concerned about going to market too soon. They usually would wait until two or three months before expiry to begin researching options. However, we encouraged them to procure their contract with eight months to go. In doing so, they avoided a 36% cost increase and saved over $2 million.
WE ARE LEVERAGING COMPETITIVE TENSION: A national food producer was given a renewal offer from their energy supplier and told that this was the most competitive option in the market.At Total Utilities, though, we understand that retailers don’t always put their best foot forward unless you give them a push. After we went through a competitive tender process, we negotiated a new renewal offer of over $500,000 less than the previous offer.
DOWNGRADING YOUR METER CAN MAKE A DRAMATIC DIFFERENCE An Auckland-based packaging customer was facing a 40% cost increase over three years. Their retailer was only giving them pricing based on their current meter configuration. This is typical in New Zealand because, unlike other countries, there isn’t a fully contestable meter supplier market. Despite being a large commercial customer, they could downgrade their meter because of their connection size. Total Utilities helped with the meter downgrade and negotiated new pricing on their behalf. As a result, they reduced their cost increase by 75% over three years and saved $200,000. The customer couldn’t believe that changing their meter would have such an impact on their new contract prices.
WE ARE ACTING QUICKLY TO HELP CLIENTS IN NEED A Christchurch-based supplier and manufacturer of commercial refrigeration equipment had been out of contract for more than two months. Struggling on their own to get offers for energy supply, they were at risk of costly spot pricing. Spot pricing changes every half hour making it a volatile and expensive route. The customer asked us for help after getting a renewal offer from their current supplier. The trouble was the offer represented a whopping 225% increase over the next 12 months.Within just five days, we presented the customer with our recommendations. We laid out several energy supply options with different retailers. The best option was 150% lower over the first 12 months than the one previous. What’s more, the new contract was backdated over two months. This meant they avoided default spot prices. Overall, the best option was 27% more cost-competitive over the term of the agreement.
The right energy procurement is crucial
Total Utilities are so much more than negotiators. We have a deep and long-term understanding of the energy market and the many factors that influence supply, price, and demand.You don’t have to settle for the first offer on the table. By engaging us, we leverage the right timing and competitive tension to get you the most favourable terms, saving you significant sums of money over the duration of your contract.
