Energy and emissions

Centuria focuses on key initiatives to minimise our carbon footprint and improve energy efficiencies.

Initiatives are set with consideration of the unique real estate assets owned by the Group and aimed at maximising value for tenants and investors, while ensuring energy efficiencies are maximised. As we work towards our sustainability targets, it is imperative that Centuria sets initiatives that allow us to achieve zero scope 2 emissions and the elimination of gas and diesel from operations where practicable by 2035.


Governance

As an area of focus, initiatives to reduce the Group’s overall energy and associated emissions are communicated to the ESG Management Committee, who provide regular updates to the Centuria Culture and ESG Board Committee. The Group will continue to focus on energy efficiency as a priority, while exploring opportunities for further emission reduction strategies.

Initiatives

Last year, we disclosed procuring our energy for several of our tenants on embedded networks through a Progressive Purchasing Agreement (PPA). This year, we have identified that the PPA has been successful in generating electricity for 14 sites throughout Australia. We will continue to develop on this initiative to increase the amount of renewable energy equivalent utilised.

In terms of electrification, we are conducting a review of multiple assets within Centuria Office REIT to identify where heating, hot water systems and cooktops could be replaced by more efficient technological alternatives. This review, to be completed by an external party, will undertake market research on newer technologies and develop cost effective solutions to identify replacement of fossil fuel sources. The findings of this report will be analysed, and used to create a strategic plan to implement the necessary changes.

Lastly, approximately 2.2MW of solar capacity became operational across the industrial, retail and office portfolios. We are committed to continuing to expand the installed solar capacity across assets including a number of solar installations in progress at the time of reporting.

Industrial assets

Industrial assets are mainly single tenanted, creating a unique opportunity to reduce emissions in partnership with our valued tenants. We seek to partner with our tenants and support their sustainability aspirations, connecting them with solar providers and the wider industry to develop innovative ways to reduce their emissions.

New industrial developments are focused on achieving leading green certification, on-site solar generation and high energy efficiency. These new assets when occupied by future tenants will be at the forefront of reduced energy consumption and lower, to almost zero, emissions in operation.

In FY22 the Centuria Industrial REIT partnered with one of our key tenants at two locations to install over 2.5 MW of solar.

In partnership with our key tenant Woolworths, a 1MW solar system was installed, supporting their goal to be powered by 100% green electricity by 2025.

In another effort supporting Woolworth's green goal, we have installed over 3,300 solar panels on a second asset.

Office assets

Office assets are often multi-tenanted and contain common spaces and whole of building services. As an internal manager for these assets, Centuria is able to directly impact how energy and the associated emissions are managed. A focus on energy efficiency, through level two energy audits and year on year improvements under NABERS drives initiatives undertaken by the Group for our commercial assets.

Centuria Office REIT (ASX:COF) have engaged a third party supplier to conduct a feasibility assessment for solar installation across the COF portfolio. Buildings identified as being feasible to have solar installed on their rooftop form part of a wider plan to reduce COF’s overall emissions. 8 Central Avenue, Redfern, was piloted as the first asset to have on-site solar installed, with construction complete in  FY23. This installation is expected to reduce emissions by 355 tonnes per annum, the equivalent of taking 147 cars off the road.

New Zealand operations

Our business in New Zealand has been making strides in expanding its portfolio with more energy-efficient buildings. In partnership with one of our clients, Hancocks, Centuria New Zealand has delivered new purpose-built premises named Te Whare Tauranga that allows the client to operate more efficiently while substantially reducing its impact on the environment.

Some of the key improvements made to the building are: 

Procurement of energy

Centuria procures its energy, and energy for tenants on embedded networks, through a Progressive Purchase Agreement (PPA). A PPA is a contractual agreement between energy buyers and sellers allowing Centuria to purchase its energy for future demand, reducing the risk of rising energy prices. A PPA has added benefits to our assets as well as to our tenants. This win-win scenario makes the PPA initiative also very attractive to a broader tenant base.

PPA benefits as an asset manager

  • Improvement in NABERS rating
  • Opportunity to lower cost for common areas energy
  • Easier to attract tenants by offering low cost energy
  • Partial expense hedge for gross lease tenants
  • Improvement in balance sheet with increased energy rating of the building.

Benefits for tenants

  • Reduced energy rates
  • Hedge energy market fluctuations with no cost volatility
  • Opportunity to hedge post term
  • Marketing and PR benefits from reduction in carbon emissions

A PPA is just one part of Centuria’s approach to energy management. The Group is also focused on a hierarchy energy management initiatives to reduce the Group’s overall energy consumption and associated operational costs.
