  2. What is Cogeneration & Advantages? • What is Cogeneration? • Simultaneous production & use of electricity & heat. • Sometimes referred to as Tri-generation or CHP (Combined Heat Power). • Advantages • Proven, low risk & short lead time. • 50% less CO2 emissions to grid. • Up to 80% energy efficient. • Removes requirement for back-up diesels. • Can uplift Green Star & NABERS ratings by 1-2 stars. • Usually cost-effective.

  3. Building Case Study – 101 Miller St, N Sydney • Building Owners – Mirvac & Eureka • Installed during building refurbishment in late 2008 • 40k sqm commercial, 10k sqm retail • Plant services base building and tenants • Tenants – Federal ATG Dept, NSW RTA, AGL • Base building & tenant energy rates competitive to grid • Plant Size • 2.4 MW electrical • 1.5 MW absorption chilling • 70% efficiency • 5 Star Green Star, 5 Star NABERS energy

  6. Getting it Done! • Do it yourself • Out sourced design & installation • Cost of about $2.0-$2.5m per 1 MW installation (including absorption chillers) • Ongoing operations & maintenance at about $120k pa per 1MW • Accept risk with future gas prices • ROI normally determines go or no-go • Outsource to distributed energy company (like Cogent Energy) • Cogent Energy designs, installs, finances, operates and maintains plant • 12 year ESA (Energy Supply Agreement) • Electricity, hot water and chilled water priced competitively to black grid energy • No gas price risk • Capital contribution usually required ( ~ $250k ) • Remote site monitoring & management
