Biggera Waters – Total Fitness

Castlehill Homemaker Centre is home to a diverse mix of large-format retailers, many of whom had high daytime energy consumption and were operating under strict electricity-supply constraints. Upgrading the site’s transformer and installing a new switchboard would have been a substantial capital expense, creating a barrier to improving energy reliability and affordability.

To avoid costly network upgrades, Clarence Greenergy delivered a behind-the-meter solution featuring a 665 kW rooftop solar array and 385 kWh of battery storage across 13 tenants. The system supplements grid supply, enabling greater use of onsite solar during peak demand and easing network constraints. As a result, tenants achieved a 40% reduction in daytime electricity costs compared to standard grid tariffs, with the project delivered at zero upfront cost. Grid electricity continues to supply the remaining demand.

Approximately 20% of the tenant’s consumption is expected to continue being supplied from the grid and will remain subject to grid pricing. For the portion covered by the onsite system, the PPA rate provides partial protection against grid-tariff movements over the term of the agreement. The renewable electricity generated displaces an equivalent volume of grid-sourced electricity. Based on expected annual generation of [INSERT kWh/year] and the Queensland grid emissions factor of [INSERT kg CO2-e/kWh], the system is estimated to avoid approximately [INSERT TONNES CO2-e/YEAR] of Scope 2 emissions for the tenant.
