World first to combine big solar and storage in Australia
The Australian Renewable Energy Agency (ARENA) is providing $17.4 million funding support for Conergy to build and operate a 10.8 MW (AC) solar photovoltaic (PV) plant with 1.4 MW / 5.3 MWh of lithium-ion battery storage near the town of Lakeland.
ARENA CEO Ivor Frischknecht said the landmark project was well placed to work alongside ARENA’s major push to deploy more large-scale solar PV plants across Australia.
“Figuring out how solar PV and battery storage technologies best work together at a large scale will be crucial for helping more renewables enter our grids,” Mr Frischknecht said.
“We know that battery storage will play a critical role in our future energy systems. The benefit of adding batteries to solar farms is simple; they store energy from the sun for use at peak times and overnight. They can also smooth solar energy output on cloudy days.
“This plant will generate and store enough renewable energy to power more than 3000 homes and create up to 60 jobs in the Lakeland region during construction.
“The global energy transition is happening faster than many anticipated and Australia is well placed to be a key player. Our growing expertise in integrating renewables and batteries could readily translate into economic opportunities including export dollars in world markets.
“Solar farms with storage can be especially useful at the edges of our electricity grids. This project adds to ARENA’s portfolio of fringe-of-grid projects, which prove how renewables can enhance the reliability of energy supply in regional Australia and benefit local networks.
“Fringe-of-grid locations face a number of challenges with reliability and outages caused by network constraints, a lack of infrastructure and long distance power lines.
“This project is aiming to be the first in the world to test a concept known as ‘islanding’ from the main electricity grid. The local town of Lakeland will be powered solely by solar and batteries for several hours during these tests.”
The project will be connected to the Ergon Energy network. A detailed battery testing plan will be implemented over the first two years of operations, culminating in testing ‘island mode’ during the evening peak. ■
