Ara Ake and solarZero collaborate on innovative winter 2023 peak solution for electricity system – enabling 30MW* of additional network capacity on-demand.
Ara Ake has announced a major, collaborative electricity pilot with solarZero in which Kiwis with solar and battery systems will contribute to the reliability of electricity supply for New Zealand, unlocking residential demand flexibility at an unprecedented scale.
The world-leading pilot integrates ''distributed energy resources'' of approximately 11,000*individual homes with state-of-the-art Virtual Power Plant ("VPP") technology* to help manage winter peak demand.
The solar batteries located throughout New Zealand will provide their capacity to the electricity market system operated by Transpower and can be called on in the rare situations when there are potential electricity shortages.
The result adds up to 30MW (roughly the same amount of power consumed by 30,000 homes) back into the grid. solarZero''s batteries take just two hours to fully charge.
"It''s great to see this kind of collaboration take place," the Minister of Energy and Resources, Hon Dr Megan Woods said. "These kinds of initiatives help to create a more sustainable and resilient energy system, which is crucial as we decarbonise and future-proof our economy."
The pilot will be the first to utilise real-time pricing changes introduced by the Electricity Authority in April this year that enable sector participants to bid and offer their demand flexibility and ''distributed energy resources'' into the wholesale market with more certainty.
"This is one of the most innovative, and globally significant, projects seen in the electricity industry in recent times. We''re entering a new era of energy in which households are active enablers of a smarter, greener and cheaper power system," says Matt Ward, Chief Executive of solarZero.
"This project demonstrates, at scale, the contribution that our own distributed energy resources can play in managing winter peaks, and it''s a great example of the convergence between innovation and collaboration, which is at the heart of Ara Ake''s purpose. The insights gained from this pilot will inform future projects," says Dr Cristiano Marantes, Chief Executive of Ara Ake.
The program will test the potential for consumers'' rooftop solar systems with battery storage – operating in a VPP – to provide scalable energy and network services traditionally performed by large-scale, conventional electricity generators.
"Electricity markets around the world are facing challenges meeting peak demand as they transition towards an increasingly renewable future," says Dr Stephen Jay, Transpower General Manager Operations. "We''ve been signalling this challenge for some time as we have integrated more intermittent renewable generation into our system. This initiative will make a small but significant difference meeting peak demand now and will help drive the transition towards the more flexible, distributed and renewable power system of the future."
"This is the first time DNL, which is part of real time pricing, has been used. It is great to see quick uptake of an exciting new market tool, one which will help pave the way to an increasingly renewables future," says Sarah Gillies, chief executive of the Electricity Authority.
Together, we are not just safeguarding our future, we are shaping it. Join us in leading change for tomorrow''s energy.

As the energy market continues to develop rapidly, the interest in solar energy storage, or solar batteries, continues to peak. But as more solar brands and models come onto the market, finding the right energy storage solution for your home can feel a little daunting. Especially when trying to grapple with the ins and outs of solar battery efficiency and capacity.
That''s why Canstar has compiled a list of the best home solar battery systems available in New Zealand. We compare factors such as off-grid capability, size and capacity, and run through some points to consider when choosing a solar battery system.
It''s important to note, however, that our advice is only general in nature. Before making any purchase decisions, it''s best to contact a licensed solar installer to discuss which options are best suited to your home and circumstances.
Price Estimate: Approx $15,000, installation extra
There''s no doubt that if you''ve been on the hunt for a solar battery for a while, that''ll you be familiar with the Tesla Powerwall 2. Arguably one of the best deep-cycle batteries for solar on the market, this model is well known for its high efficiency, capacity and its ability to be seamlessly added to an existing or new system.
Despite carrying a higher price tag than most other models, this unit still stands as one of the best for energy storage. Plus it has a very high weather rating, allowing it to withstand extreme temperatures in outdoor settings. The Tesla Powerwall 2 also comes with a warranty of 10 years.
Sizes Available: 13.5kWh
Price Estimate: Approx $14,000, installation extra
When it comes to a battery with high capacity, you can''t look past the RedFlow ZCell. Built using a flow design, this battery uses a Zinc Bromine liquid to run the system, making it more durable to discharge energy at full capacity than other lithium-ion based batteries.
One of the smallest batteries of its kind, the RedFlow ZCell is able to run at 100% capacity at all times and can be seamlessly integrated within an existing or new system.
The ZCell also comes with 24/7 web-based battery monitoring that can be accessed via a laptop or smartphone. As is standard with most battery models, the RedFlow ZCell comes with a 10-year warranty, and can be coupled with multiple other ZCell''s for a larger storage capacity. RedFlow''s batteries are also made from materials that are easily recyclable and reusable.
Price Estimate: Approx $4000-$21,000 depending on size, installation extra
This battery has a special modular design that allows its size and capacity to be easily expanded. It can generate up to 256kWh, when 16 battery stands are integrated together in parallel, so is perfect for powering a home looking to ease into self-sufficient power gradually. BYD Premium LVS batteries also come with a 10-year warranty and are suitable for outdoor installation.
Sizes Available: 4, 8, 12, 16, 20, 24kWh
Price Estimate: Approx $2500-$3500, installation extra
For a small-sized battery with a reasonable price tag, it doesn''t get much better than the Enphase AC Battery. Delivering low upfront costs, high efficiency and real-time monitoring through the Enphase Enlighten app, this model is considered to be a suitable storage unit for homeowners just making their way into the battery space.
