Summerville Solar Farm

Tiedot hankkeesta

The Project

OX2 is planning the Muswellbrook Solar Farm, featuring a 90MW solar farm and a 90MW Battery Energy Storage System (BESS) across 240 hectares. The project is located approximately 3km east of Rappville on private land.

The project will connect to NSW’s electricity network via a short underground connection to the existing 132 kV Lismore to Koolkhan overhead line to the southeast of the site.

Operations are expected to begin by 2027.

BESS

Covering 1.9 ha of land the BESS will act as a large-scale power supplier and connect to NSW’s electricity transmission grid.

It will store up to 90MW of energy which can supply up to 4 hours of electricity. The BESS will store energy for use when it's needed most. It will provide reliable and affordable power, helping utilities quickly deliver electricity during peak times, outages, or shortages. This will improve energy security for NSW.
