Hybrid Solar Power Station

Background:

  • 2007: Resort Management decides to investigate options for renewable power generation and emission reductions. Tropical Energy Solutions conducts Energy Audit and identifies opportunities to combine comprehensive load management with hybrid power system development. Average daily fuel consumption reduced from 500 litres to 300 litres with equal reductions in emissions and costs.
  • 2008: Federal Government funding approval obtained to support construction of Hybrid Power Station. Tropical Energy Solutions provides the Hybrid Power Station System Design services. Hybrid Power Station built during November and December 2008, and was commissioned on the 20th of December 2008.

Achievements as at March 2009:

  • Reduction of Resort peak load by 42%, Reduction of annual load by 35%.
  • Reduction of diesel consumption from 550 litres per day to 160 litres per day = 142,000 litres/year.
  • This resulted in a reduction in CO2 emissions by 70% = 380 tonnes CO2/year.
  • Reduction of genset running hours by 29%, Reduction of genset maintenance cost > 50%.
  • Reduced dependence on fossil fuels, barging services, and fuel storage facilities in the Marine Park.

2011

  • Added 24 new BAE batteries and 3 SMA SI5048 inverters to the original Hybrid Solar Power Station adding an extra 15kW of power and 50kWh of storage, taking the total amount up to 45kW of power and 150kWh of storage.

2012

  • Placed additional 32 solar panels onto existing buildings to increase our solar renewable capacity by 8kW or 40%.
  • Installed a SMA tripower 8000 inverter.

2013

  • In December 2013, the Resort in conjunction with Peter Libretto from Enertech Solar installed an additional 60 solar panels to the existing 128 panels on Island.
  • The 250 watt REC panels were chosen as they are considered some of the world's best.
  • Alongside the additional solar panels is an SMA 15,000 tripower Inverter.
  • Replaced the existing 90kW generator with a brand new Denyo DCA generator to reduce our fuel burn by an additional 30 litres/day and reduce the noise footprint with this quieter generator.

2014

  • In April 2014, the Resort in conjunction with Peter Libretto from Enertech Solar installed an additional 125 solar panels to the existing 188 panels on Island.
  • The 260 watt REC panels were chosen as they are considered one of the world's best.
  • Alongside the additional solar panels will be two SMA 15,000 tripower Inverters.

Future Developments:

  • System extension, including the installation of additional solar PV and more energy storage.
  •  Installation of water harvesting and energy efficient improvements to desalination plant.
  • A plan to eliminate the reliance on fossil fuels to power the Resort.

Our ultimate goal is to have total renewable power supply use by 2019.
