The Ministry for Business, Innovation and Employment opened consultation on a discussion document about amendments to the Electricity Safety Regulations to expand the permitted voltage range for electricity supply. Rewiring Aotearoa's submission believes changes are needed to prepare for the rapid adoption of customer energy resources, and electricity distribution companies need to be compelled to allow export limits to be increased.
Overall, Rewiring Aotearoa welcomes the proposals made in the consultation. It is an important step towards better preparing the Aotearoa NZ’s energy system for the efficient and rapid rollout of customer energy resources (CER) across homes, farms, and businesses.
However, changing the standards does not compel EDBs to amend their existing export limits on CER. The Government (following this consultation) should set an expectation that EDBs move quickly to integrate these updated voltage standards into their export limits. This would effectively double the default export limit for households, encouraging the installation of larger solar systems. These systems would not only help reduce energy costs but also contribute to greater energy security by storing more energy for peak winter demand, thus helping to keep water in hydro dams when it's needed most. A phased approach could delay these benefits, while immediate action will support a faster transition to a more resilient, decentralised energy system.
Part of Queenstown is being turned into a testing ground for ideas that could one day help cut your power bill. A new energy sandbox is being scoped to test ideas like energy sharing, plug-in solar and solar for renters in a controlled area, before any wider rule changes. Rewiring Aotearoa's Josh Ellison spoke to Ingrid Hipkiss.
As electrification blossoms and homes save money by getting off gas, we need to prepare for more electricity use. That doesn't necessarily mean more expensive upgrades to poles and wires paid for by customers on their bills. It could also be lines companies innovating and ensuring that they make the most of new technology like solar, batteries and two-way charging that can provide generation and reduce the pressure at peak times.
