Energy efficiency

Bunnings remains committed to implementing more energy-efficient ways to operate its business.

During the financial year, a further nine stores had solar photovoltaic (PV) systems installed including Wangara, Australind and Esperance in Western Australia, Prospect, Seaford and Munno Para West in South Australia, Cairns Central and Rockhampton in Queensland; and Bellambi in New South Wales.

The small-scale systems, up to 100 kilowatts, are generating between 10 and 20 per cent of each store’s energy needs, and those stores with larger scale systems are producing up to 35 per cent of each store's energy needs - all from renewable energy.

In addition to this, the solar PV system at Bunnings Warehouse Alice Springs was expanded from 100 kilowatts to 475 kilowatts, and battery storage was introduced; the first of its kind in the network. The system and battery storage are expected to provide 80 per cent of the store’s energy needs.

At the end of the financial year solar PV systems were installed at 23 stores across Australia, covering 25,000 square metres of roof area. Further installations will continue over the next 12 months.

Bunnings also continued to install energy-efficient LED lighting in new stores and upgraded stores progressively, and retrofitted selected existing stores. 12 existing stores had LED lighting installed throughout the year, with 26 stores retrofitted to date.

Further new generation solar PV systems and LED retrofits are planned for the coming financial year.
