About Terang BESS

The Terang BESS is located approximately 19 kilometres west of Camperdown, near the town of Terang in the shire of Corangamite. The site covers approximately 3.0 hectares of agricultural land.

The facility will comprise energy storage and conversion infrastructure. Batteries will be arranged and enclosed within approximately 82 Battery Energy Storage System (BESS) units and supported by power conversion systems, inverters, and transformers. The battery will connect directly to the Terang Terminal Station through an overhead transmission line connection.

Approval for the project was obtained in May 2021. Construction of the BESS facility will take approximately 20 months with intensive construction (civil works, delivery and electrical installation of batteries, inverters and transformers etc.) occurring over 12 months. During construction approximately 50 people will be employed.

Once operational, the BESS facility will be regularly inspected, tested, and maintained by onsite personnel. Safety is a key consideration for all operational activities.

Why Terang?

The site has been carefully considered based on several factors. The Terang BESS is located next to the Terang Terminal Station which is the main source of supply for over 70,000 customers in Terang and the surrounding areas of Colac, Camperdown, Cobden, Warrnambool, Koroit, Portland, and Hamilton. A range of embedded renewable energy generators are installed on the sub-transmission and distribution systems connected to the Terang Terminal Station. This mix of embedded generators will be complimented by the Terang BESS which will deliver much needed grid stabilisation and security.

The location also allows for a short distance to connect and will therefore limit the potential for impacts during construction and operation.

The BESS facility will also help diversify jobs within the local economy by introducing a long-term sustainable industry providing economic and social benefits to the local and regional community.

What it looks like?

The design and layout of the Terang BESS has carefully considered in accordance with local planning laws and principles to protect the amenity of nearby residents. In particular, the BESS has been constrained to only a small, efficient envelope, approximately 3 hectares in size.

The design incorporates landscaping to provide a visual screen for residents in the vicinity of the project.

The BESS connects directly into the existing Terang Terminal Station which sits next to the site and is owned and operated by AusNet.

The Technology

Energy storage is a key technology enabling the transition to green energy. As solar, wind, and other renewables transition to become Australia’s primary energy resources, it will be harder to preserve the energy network’s resilience. The intermittent nature of renewables requires energy storage solutions to ensure that the supply of energy matches demand (both in terms of volume and timing).

Grid-scale battery facilities, like the Terang BESS, is an increasingly popular energy storage solution. BESS facilities can balance the grid due to its fast-responding and flexible nature. Additionally, as the energy market develops, BESS facilities will continue to provide a clean source of capacity to the electric grid by shifting renewable energy from periods of high supply to times of high demand.
