Yamba Fair

A busy neighbourhood shopping centre anchored by Coles, K Hub and Priceline Pharmacy needed to reduce its tenants’ electricity costs without requiring capital investment from the centre or its tenants.

Clarence Greenergy installed a 271 kW rooftop solar system across eight tenancies, sized so approximately 75% of generation is consumed on-site during peak trading hours, with the remainder exported to the grid. The system supplements — not replaces — each tenant’s grid supply. Based on modelled generation and usage at the time of design, it is expected to deliver over $20,000 in combined annual savings. Actual savings vary by tenant and depend on grid tariffs, system coverage and daytime usage patterns. The project was delivered on time and within budget with zero capital outlay from both the landlord and tenants.

For consumption supplied by the rooftop system, the PPA rate provides partial protection against grid-tariff movements over the term, while remaining usage is supplied from the grid and subject to grid pricing. On-site generation displaces an equivalent volume of grid electricity. Based on expected annual generation of 220,458 kWh/year and the New South Wales grid emissions factor of 0.64 kg CO2-e/kWh, the system is estimated to avoid approximately 141 t CO2-e/YEAR of Scope 2 emissions across participating tenants.
