Harvest Battery Energy Storage System (BESS)

OX2 is the leading developer of onshore wind in Europe. As an industry pioneer, we are active in eleven markets and offer fully customised renewable energy solutions involving several technologies, including wind and solar energy, in addition to hydrogen and energy storage projects. We design and build sustainable projects and tailor them to meet our customers’ needs. OX2 has a proven business model and in-house expertise at every step of the process – from project inception and financing to engineering and design, permitting, procurement, construction, and technical and commercial management. Our mission is to accelerate access to renewable energy. We see ourselves becoming the leading provider of renewable energy solutions globally, thereby powering the great shift.

BESS facilities generally use lithium-ion to store the electricity until it is ready to be distributed to the network. BESS facilities allow energy generated from another source (such as a wind farm) to be stored until it is needed. BESS facilities improve grid reliability by storing low-cost electricity when there is an oversupply of electricity or during periods of low demand/high generation so that electricity is available when demand is higher. In fact, BESS can reduce electricity costs for communities by lowering peak demand charges and providing access to cheaper off-peak electricity. The BESS's fast response capability also provides ancillary services to maintain grid power quality at a standard level. Additionally, BESS can act as a backup power source during emergencies like bushfires, ensuring that critical infrastructure (hospitals, emergency services, water systems) remains operational even if the grid is disrupted.

BESS facilities contain several key components, including battery units, inverters and transformers. The final composition of a BESS facility will depend on the BESS technology used, the BESS supplier, and the facility's size. Where possible, BESS facilities are co-located with or near a grid connection point (such as a terminal station), therefore minimising the need for additional connection infrastructure.

Large-scale BESS facilities are expected to have an operational life of approximately 15 to 20 years and are typically monitored remotely, without the need for permanent on-site staff. Staff are, however, required to access the site from time to time to undertake inspection and maintenance activities.

BESS facilities are typically a group of containers storing battery systems inside. The number of containers depends on the batteries being used and the space available at the site. However, BESS technology is continuously evolving, with BESS components becoming increasingly more efficient and compact in size.
