Terry E. Jones, Distributed Energy & Innovation Manager, Networks Modernisation Division, SP AusNet will share his insights – exclusively with SGA members – on the storage projects at SP Ausnet.

Thursday 1st May 2014 from 10-11am

Book your free seat at this Telecon at admin@smartgrisaustralia.com.au.  Dial-in details will be provided in a follow up email.

Grid Energy storage (GESS)
This project aims to explore and prove the functionality of a substation scale energy storage system in anticipation of lower battery prices and further deployments in SP AusNet’s network.
The trial was supported in the 2011-15 Price Determination by the AER who approved a Demand Management Innovation allowance and specific funding for this trial.

The project is to install a 1 MW / 1MWhr battery system to support the peak load onto an Urban 22KV feeder. It is expected that the trial will provide operational data to verify performance of the battery, inverter and the controller in supporting the grid for peak demand, voltage and power factor.  The system includes a 1MW diesel generator set to extend the MWh rating of the battery system to provide full coverage of the peak demand period. This has been done in order to keep the costs of the entire system down but to fully simulate a larger battery system. All units are containerised so that they can be moved to alternative locations in the future.

System supplied by ABB with Samsung batteries ready for service 1st December 2014.

During the 2 year trial the system will be used to manage; peak demand, voltage imbalance, pf correction, VAR control and various other power quality functions.
We are working with ABB and will encourage papers and dissemination of learninigs for industry wide benefit.

Residential Storage Trial
The Residential Battery Storage Trial aims to deploy a 6.6kWh battery combined with a solar PV (3KW and 1.2KW)  systems into domestic dwellings to:

1. Determine whether battery storage can be used to reduce residential peak demand.
2. Determine whether self-consumption of solar PV generation can be used to manage network voltage rise issues.
3. Determine the economic viability of residential battery storage as a means to manage peak demand and thereby defer asset investment.

Ten systems were ordered from MPower and the trial has been fully operational during Summer 2013_14 across a varied demographic of selected employee homes.

One further summer is planned for full operation and data acquisition (2014_15) where we aim to optimise the settings and functionality of the systems.
