JCU Townsville – Central Energy Plant with Thermal Energy Storage
Introduction
- Site building program to 2010 will increase current floor area by 35%.
- Current site maximum demand is 7.4MW (2006).
- MGF’s energy model predicts site maximum demand to be 10MW in 2010 (business as usual scenario)
- Proposed system design with Central Energy Plant (CEP) and Thermal Energy Storage (TES) provides a maximum demand of 5.4MW in the 2010 scenario.
- The proposed system will be the largest TES site in the southern hemisphere.

System Outcomes
- Flat Site Power Profile. Reduction in maximum demand from 10MW to 5.4MW in the 2010 scenario.
- Reduction in green house gases of 12,000 tonnes pa.
- Simplified Maintenance.
- Lower operating Costs.
- Largest TES installation in the southern hemisphere.
Utility Benefits
- Improved utilisation of power transmission & distribution infrastructure
-
Defers capital expenditure, Improves utilisation factor, Improves revenue generated
- Reduces transmission losses (environment)
-
Reduced peak load transmission losses (I²R), Reduced min load capacitance losses
- State wide Potential if viability can be improved through tariff reform
- Other Industries which can benefit from similar installations
-
University campuses, Hospitals, Larger scale district cooling applications, Large school campuses
