This report presents Sunverge’s findings from its investigation and engagement with members of the Daintree community and key stakeholders including representatives from Queensland’s Department of Energy and Water Supply, Douglas Shire Council, Wet Tropics Association and the Jabalbina Aboriginal Corporation.
As part of the process, Sunverge reviewed a number of existing studies and reports relevant to power supply issues in the Daintree community, including the 2017 Ener-G report and Ergon Energy’s engineering 2013 Daintree Supply Report. Many of these studies relied on information contained in previous reports with little reliance on gathering primary data to establish load profiles for energy and load requirements.
Sunverge sought to improve the accuracy of the energy requirements analysis and thus the accuracy of supply option definition by undertaking real metered data analysis, spatial survey analysis, and analysis of Sunverge’s own load data set for Far North Queensland combined with standard power system planning and forecasting practices.
Sunverge undertook spatial analysis, gathered energy consumption data from a number of sites and developed load profiles to establish the community power requirements. In the process Sunverge discovered significant differences between the different regions within the Daintree.
Sunverge also conducted meetings with a number of OEMs through a market sounding process to develop indicative costing at concept level for a range of solutions applicable to the Daintree area for comparison purposes. The network design process adopted was similar to that used by Ergon Energy. The expected Load and Generation spatial arrangements determined the number and expected type of transformers, synchronous machines and cables, thus providing a more quantitative cost estimate.
