How we can help

3. Connection services

After you develop a project scope and select a community-supported location, you can start the connection process with us. Our engineers must provide a technical assessment for the battery connection before we can offer a connection agreement.

Visit Connecting a community battery to see what you need to do to connect a 30kW to 1.5MW community battery. 

4. Network tariffs

Community batteries connecting directly to the grid are typically assigned to commercial network tariffs based on their size and usage patterns.

On 1 July 2026, we are introducing a new neighbourhood storage tariff trial for community batteries. The trial will run for five years, until 30 June 2031 and will help us understand how community-scale storage systems, such as community batteries, respond (charge and discharge) to price signals. This information will help us better manage our network.  

The tariff structure is designed for community-scale storage systems installed on our low-voltage network. There are two tariffs, based on inverter capacity:  

• Medium – up to 250 kW
• Large – 250 kW to 1 MW

5. Letters of support

We provide letters of support for community energy groups seeking government or third-party funding. We’ll need your project details, scope and intended benefits.  

The letter of support states we are aware of the project and can provide the above listed services and/or what network tariff might apply to the project. We do not carry out any analysis or technical assessments before writing the letter of support.
