Increasing capacity of available on-site storage
South Port NZ is a deep-water port on a 40-hectare Island located in Bluff, New Zealand, from where it provides a full range of marine services, cargo and container shipping, and on-site warehousing for domestic and international customers.
In 2019, South Port NZ partnered with Total Utilities to better understand the actual power demand of the site, identify opportunities to increase existing storage capacity and deliver customised solutions to meet the needs of customers on the island. An initial supervisory control and data acquisition (SCADA) solution was proposed by a 3rd party vendor to address the needs, which came with a price tag of NZD$800,000.
As a partner of Centrica Business Solutions, Total Utilities supplied and DECOM Electrical installed Panoramic Power wireless, device-level, energy monitoring sensors at the port. After a month of capturing the data and analysing it using Centrica Business Solutions’ complimentary energy management software, PowerRadar, South Port NZ deployed an additional 229 Panoramic Power sensors and over 30 communication bridges across the port with minimal interruption to operations. Within days, the on-site infrastructure team gained real-time, granular visibility into the energy consumption and operation of their critical assets across the site. The easy-to-install energy insights solution now transmits data securely via cellular connectivity – monitoring more assets than the initial proposed SCADA solution, at a fraction of the cost.
“PowerRadar provides real-time data on demand versus capacity which allows us to maximize our electrical PowerRadar provides real-time data on demand versus capacity which allows us to maximise our electrical infrastructure while minimising risk. Being a small team looking after the engineering infrastructure of a 40-hectare island, takes a lot of our time. Having something like this that provides us with real-time, easy data, provides efficiencies saving us a lot of time.”
Jason Paul, Project Engineer, South Port NZ
Prior to installing Panoramic Power, the infrastructure team had been unable to determine the maximum number of refrigeration storage units that could be brought online safely at any given time. As such, only eighty electrical plugs were available at any time – one per refrigeration storage unit – within two substations dedicated to handling refrigeration reefers for port customers. With real-time visibility of the measured load across the electrical substations in PowerRadar, the infrastructure team realised that the electrical capacity for these substations was being underutilised – adding more plugs to these substations doubled the reefer capacity to 160 without any major or costly upgrades.
Streamlining resources for managing assets
One of the hurdles of the day-to-day operations at the port was the amount of time spent in collecting data from submeters to invoice port customers. Typically, it would take one of the port’s personnel three days every six months to capture the readings from all 51 revenue meters around the port, regardless of the weather conditions. Using PowerRadar, it now takes them only 10 minutes to collect the meter information before it is passed to their finance team for invoicing customers.
With the monitoring of the sewer pump stations at the port using PowerRadar, the infrastructure team now receives real-time alerts on the status of the motors operated at those stations. This has enabled the reallocation of limited resources to other critical assets at the port. One of the benefits of such reallocation was the detection of surface water ingress at the pump stations by the infrastructure team, having compared the measured power draw of the pumps to available rain data. It is now possible for the infrastructure team to track the amount of surface water ingress at each station on days with rainfall and implement any corrective measures.
Effective planning for infrastructure projects
When trying to identify which assets at the port should be prioritised for capital upgrade projects, the infrastructure team relied on the energy consumption data in PowerRadar. This enabled the team, particularly in the design phase, to plan future expansions as well as ongoing maintenance of the existing electrical infrastructure at the port.
An energy audit was completed for one of the large electrical substations being monitored at the port. The findings resulted in the approval of a large capital project for implementing changes to the substation, and switch board running the Cold Stores and an expected payback within one year.
To ensure the reliability of the substations to handle loads within the port’s electrical network, especially during periods of storing a large number of refrigerator containers, the infrastructure team uses the real-time energy dashboard within PowerRadar to track the maximum power demand from the combined substations. If the power draw approaches 1 MW, the team can begin to consider bringing backup generators online or other ways of taking some load off the power grid at the port.
By choosing to implement Panoramic Power across the site, South Port NZ reduced their capital expenditure by US$600,000 and achieved an increase of 80% in container storage days compared to the previous year. In addition, South Port NZ is now able to report on their carbon footprint annually, provide automatic reports on monthly energy use to port users and streamline efforts in identifying areas of high energy usage for investigating ways to lower the peak demand at the port.
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.

Total Utilities has assisted many clients in making long term immediate savings by identifying power factor issues and providing turnkey services to rectify the problem.
Pushkar Kulkarni from Total Utilities completed the site review and NABERSNZ Assessment of Watercare House. Here he provides additional commentary to the original published case study, highlighting the specific benefits of a NABERSNZ tenancy rating.
“A NABERSNZ tenancy rating is an ideal tool for tenants as it shows them how their day to day operations impact their energy performance. It can also determine how well they manage energy and identify the opportunities that may exist to improve energy performance.
In an increasingly competitive market place and businesses look for a point of difference by delivering on their corporate and social responsibility, and think about long term business sustainability, tools like NABERSNZ are a good demonstration of their willingness to “walk the talk”. It reflects where they are now with respect to others and what benefits they can get by improving their NABERSNZ rating. I definitely feel that ratings will become increasingly important in New Zealand.
Equipment directly impacting the tenancy rating of Watercare are: lighting, computers, and client specific plug load etc. They are limited to what they can do with the lighting connections and zoning due to way in which these were originally designed. This has had an impact on the rating. If a NABERSNZ rating was a factor that developers and contractors were informed of during the design/build stage, then there is good chance that the lighting connections and zoning may have been designed differently.
In my opinion the occupancy density, clever use of all areas, and using lighting controls are the main factors that have resulted in a 4-Star NABERSNZ tenancy rating for Watercare. The rating demonstrates it’s a very good start and platform for Watercare to understand where they are at compared to the wider market and examine strategies on how they can improve going forward.”
Scoring a first-rate NABERSNZ 4-star tenancy rating for energy consumption at its office demonstrates an Auckland company’s commitment to the environment.
Auckland water provider Watercare Services Limited is the anchor tenant in an eight-level office block constructed in bustling Newmarket in 2013.
73 Remuera Road is the first Green Star rated commercial property in the district and reflects the growing demand from corporate tenants for green principled, energy smart work spaces.
Watercare occupies three of five office floors in the building.

Why NABERSNZ?
With water being its core business Watercare has the environment and energy issues at the top of its agenda.
While its head office is housed in Green Star rated Watercare House the company’s sustainability manager Roseline Klein says the company wanted to understand its everyday energy performance across the three floors it occupies in the building.
It was the missing ingredient.
We wanted to know where we were at with our energy performance, how well we were doing and where we could improve. We’d heard about NABERSNZ so we did some research online. It’s a great tool, it provides a benchmark and it drives best practice.”
– Watercare Services Limited Sustainability Manager Roseline Klein
NABERSNZ in Action
Watercare Services Limited sustainability manager Roseline Klein says undertaking a NABERSNZ rating over its 7563 square metres of office space has proved to be “a painless process”.
The meterage required for a rating was already in place – 18 meters had been installed in the building during the construction period to aid fine-tuning of systems and utilities.
The company took advantage of the free NABERSNZ feasibility assessment which determines a building’s readiness to get started with a rating.
“It made a big difference for us and took away the humdrum business of counting 644 computers and documenting the configuration of staff plus it set a timetable, provided a checklist and saved us time,” says Roseline.
NABERSNZ assessor Pushkar Kulkarni from Total Utilities says lighting, computers and occupant specific plug load have the biggest impact on a tenancy rating.
He says clever configuration of work spaces, occupancy density and sensory lighting controls have resulted in Watercare’s superb 4 star result.
The Value of NABERSNZ
Watercare says it wants to model water and energy efficiency and its 4-star NABERSNZ tenancy rating shows its credentials.
Sustainability manager Roseline Klein says the rating has been “a great experience” and has pushed the company to look hard at its resources and ensure they are better used.
“It’s spearheaded change. For example we’re now trying to ensure our procurement process is not always about cost but energy efficiency too. We’ve recently retrofitted our gym with water efficient shower heads which use nine litres per minute compared with 12 – they offer a better shower experience and use less water and energy,” she says.
Roseline believes if a NABERSNZ rating was compulsory it would encourage energy awareness and help tackle climate change.
“For example Aucklanders are the lowest users of water because it is charged volumetrically so whether you are sustainably-minded or not your invoice reminds you not to waste, to think of water efficiency. A mandatory energy performance rating would have the same effect for landlords and tenants.”
In Australia a NABERS rating is compulsory for commercial offices over 1,000 square metres while a range of mandatory energy performance ratings exist in Europe.
NABERSNZ assessor Pushkar Kulkarni says as Kiwi businesses increasingly look to deliver on corporate and social responsibility and think about long-term business sustainability a NABERSNZ rating demonstrates a willingness to ‘walk the talk’.
“The NABERSNZ tool is set to become increasingly important in New Zealand.”
