Overview
Blanche BESS is a proposed 125MW/500MWh battery energy storage project located in Compton, South Australia. The project will occupy about 7ha within a rural property, close to the existing Blanche substation.
Subject to obtaining the necessary approvals, construction of the proposed project would be expected to commence at the beginning of 2027, with operations due to begin at the end of 2028. The estimated investment value of the proposed project would be more than $220 million.
Subject to obtaining the necessary approvals, the Blanche BESS would comprise of shipping containers which are fitted with the battery units and control equipment associated with inverters and power transformers. The layout would be arranged in a grid pattern with enough space to allow access around each unit. A substation would be constructed within the project area to enable connection via underground cabling to the closely located Blanche Substation, owned by Electranet.
