National Carbon Bank of Australia Commercial and Public Lighting ERF Aggregator Project

National Carbon Bank of Australia Commercial and Public Lighting ERF Aggregator Project is an energy efficiency project located across numerous aggregated commercial, public, and industrial sites nationwide in Australia. It was registered in June 2020. Due to the aggregated nature of the project, it does not cover a single continuous land area, but rather spans multiple urban and commercial postcodes across the Australian Capital Territory, Northern Territory, Queensland, South Australia, Tasmania, and Western Australia.

Commercial and Public Lighting projects involve improving energy efficiency by modifying, replacing, or supplementing existing lighting systems in serviced areas. Standard methodology requirements involve demonstrating quantifiable energy savings and utilizing certified lighting designs. In this project, activities focus on installing highly efficient 240V LED lamps to significantly lower grid electricity demand, which in turn reduces greenhouse gas emissions.

Because the project sites are located entirely within built environments and commercial facilities across the continent, standard agricultural environmental conditions do not apply. The typical land use of the surrounding regions is urban, commercial, or industrial. As it operates nationwide primarily indoors, the geographic footprint encompasses highly diverse climates ranging from semi-arid to high rainfall, and various soil types from coastal sands to heavy clays, depending on the specific state and city of each upgraded facility.

National Carbon Bank of Australia (NCBA) acts as a third-party aggregator for this project, allowing smaller businesses that cannot meet the 2,000-tonne minimum ERF threshold on their own to bundle their lighting upgrades into a larger parcel. Interestingly, while the ERF's Commercial and Public Lighting Methodology was officially revoked in April 2022, NCBA's early 2020 registration allows them to continue offering abatements and adding new sites under this project until its crediting period ends in 2027. One notable participant in this aggregation is equipment manufacturer WesTrac, which upgraded 4,278 light fittings across 33 buildings, generating an estimated 21,420 ACCUs over the lifetime of the project.
