Once all necessary approvals, agreements and authorisations have been obtained, the Beresfield BESS can commence construction activities.
Construction typically takes between nine and twelve months and involves site preparation, delivery and installation and testing and commissioning stages. Preparation of the site includes civil works that make it suitable for the BESS equipment, such as earthworks, drainage and foundations. Following this, equipment, such as battery module enclosures, inverters, transformers, switchgear and ancillary systems are delivered to site, installed and interconnected. The last step in construction is the testing and commissioning process where the BESS’s installation is validated and made ready for operation.
The site is expected to operate for approximately twenty years. During this period the operational work will generally involve monitoring, testing and maintenance of equipment as well as receipt of goods, removal of waste and other general site maintenance (such as care of groundcover). During this period the site will be monitored and controlled remotely with a few people coming to site periodically for the other activities.
At the BESS end of life, the site will be remediated. This involves the removal of all above-ground infrastructure and any works needed to return the land to a safe, clean and stable state.
