New Zealand is transitioning most of its remaining fossil-fuelled generation to renewables-based intermittent and variable generation. Having a greater proportion of intermittent and variable generation creates challenges for how the power system operates, including the reliability and security of.
A BESS captures, stores and discharges electricity. This provides the flexibility to respond to peaks and troughs in market supply and demand, which is a core challenge for developers of generation and users of electricity alike. The price arbitrage opportunity which can be realised by running a.
transferring and using energy. In New Zealand, our hydro lakes store energy on a large scale. However, until now we have had limited options to store electricity cost-effecti ly, close to where it is used. It can also store local sources of generation, such as rooftop solar, and smooth out the.
Save you money on power bills and avoid some effects of rising electricity prices by drawing less electricity from the grid. Reduce reliance on the grid and provide backup power during outages or extreme weather events (if the home has battery storage). Reduce the need for electricity.
The NZ Battery Project was set up in 2020 to explore possible renewable energy storage solutions for when our hydro lakes run low for long periods. A pumped hydro scheme at Lake Onslow was one of the options being explored. The Government stopped the Lake Onslow investigations in late 2023. MBIE is.

Is solar PV a viable energy solution for New Zealanders?As solar technology advances and battery storage becomes more affordable, more New Zealanders are considering solar PV as part of their energy solution. A solar PV system can operate on its own, supplying power directly to a home or business. However, many systems are also connected to the wider electricity network.
When will taup start building a battery storage system?In May 2025, Taupō District Council granted resource consent for the project. This means we can start to think about when we want to build the first stage of the battery storage system. The next major milestone will be when we consider whether to proceed with the project and we’re aiming for that decision to be mid-2026.
Why did the New Zealand Energy Authority make regulatory changes?The Authority started making regulatory changes several years ago in preparation for the uptake of new and emerging technologies such as BESSs in New Zealand. 3.2. In 2018, the Authority published its view that a BESS injecting energy into a network met the definition of ‘generating unit’ in the Co
The uptake of BESS in New Zealand is particularly important given that it can help to solve one of New Zealand''s biggest energy challenges – meeting peak demand. In recent
A new battery storage system will complement our existing renewable energy generation capabilities. We''ll charge up the batteries with power primarily from the National Grid when there''s plenty of power around, and then use
