2 Cogent Energy Company Overview Cogent is a distributed energy (DE) company - we build, own, operate & maintain co/trigeneration facilities for large sites commercial buildings, hospitals, shopping centres, government complexes, industry and also precinct energy solutions. Cogent provides co/trigeneration plants that integrate into site distribution systems control, electrical, hot water, chilled water, steam and condenser water. Cogent currently have 10 operational facilities in service. 3 currently under construction. Cogent is a 100% owned subsidiary of Origin Energy, Australia s largest fuel integrated generator retailer. Cogent is constructing Australia s first district energy project in Dandenong (6MWe upon stage 2 completion) Cogent is advancing with the City of Sydney to deliver the first stage of the Decentralised Energy Master Plan (60MWe) 2

4 Australia s First Virtual Trigeneration Precinct The trigeneration plant at Coca-Cola Place consists of: 774kW MWM, low NOx, gas fired reciprocating engine coupled to a 415V generator located on level B2 which provides power to the base building. 650kW two stage effect Broad absorption chiller located on B1 mezzanine level. The absorption chiller utilises both engine jacket and exhaust heat and can supply either chilled or hot water to the building. Control, metering and switch gear that will manage the plant and interface to the site s main switch boards and the grid for safe operation. 4

6 Coca Cola Place Challenge System designed and built by third party Complicated commissioning Assistance required from Cogent Energy Building s initial winter load insufficient for engine s minimum operating load Building s summer load sufficient for engines minimum load for operation, however Once absorption chiller came on, electric chillers turned off, load was again not sufficient Find load for the engine Deutsche Bank Place, 126 Phillip St. 6

7 Key components of the arrangement Cogent leases Coca-Cola Place s trigeneration energy centre from Investa increasing the building s capital value and the overall rental returns for Investa. Two Energy Service Agreements (ESA) allow Investa to purchase electricity, hot water and chilled water from Cogent, as well as top-up peak and off-peak electricity for both sites. Cogent will purchase the gas consumed by the plant and provide the monitoring, operation and maintenance of the plant for the duration of the long-term agreement. 7

8 Cogent Energy - Precinct Heating and/or Cooling The Next Step in Distributed Generation Provision of thermal energies from one or more local energy centers to multiple precinct sites is also possible with an appropriate thermal reticulation network Cogent has significant experience in the specification and design of thermal reticulation networks 8

12 City of Sydney Sydney Vision The City has an ambitious plan to reduce greenhouse gas emissions by 70 per cent and for the city to have capacity to meet up to 100 per cent of electricity demand by local electricity generation and 10 per cent of water supply by local water capture by The City s goal is to produce 70% of their electrical needs from Trigeneration and 30% from renewables. 12 Image Source: Bruce Taper, Kenesis, Presentation; Green Transformers: Revolutionising energy generation for a Sustainable Sydney - 22/7/08 More

The Stand Alone Trigeneration solution can produce ~20% saving, whilst the Trigeneration solution integrated in the a precinct can provide a total of ~40% savings, this in monetary terms over a year.

20 Enabling Precinct Scale Co/Trigeneration in Australia (from the City of Sydney s Decentralized Energy Master Plan - Trigeneration) 1. Reform BASIX within Low Carbon Infrastructure Zones 2. Modify the city of Sydney s development control plan to reflect the Low Carbon Infrastructure Zones 3. Recognise the decentralised energy network in mandatory disclosure and NABERS 4. Introduce rate variations 5. Incentivise energy efficiency and low carbon energy 6. Standardise connection fees for gas and electricity networks 7. Introduce demand management rebates 8. Make state and federal infrastructure funds available 9. Introduce environmental upgrade agreements and infrastructure levy for decentralised energy 10. Introduce a price on carbon (Done) 11. Remove the regulatory barriers to decentralised energy 12. Low Carbon Zone recognition scheme 13. Streamline state environmental planning policy planning approvals for decentralised energy 14. Streamline easements and access arrangements for decentralised energy 15. NSW Handbook 20

21 Facilitation of Mainstreaming Cogent Energy Value Proposition Energy efficiency up to 80% energy efficient. Green credentials up to 60% reduction in carbon emissions - improves Green Star & NABERs energy ratings by up to 2 stars. Emergency back-up can be configured to displace back-up diesels. Financed - minimal capital outlay, just one monthly energy bill. Reduced Administration from the design phase through to authority approvals, installation and actual operation, Cogent involvement will significantly reduce the administrative requirements of the client. Flexibility and innovation Multiple feeder / site capability with cogentpower! Skin in the game - Ongoing engagement by Cogent is ensured through embedded incentives to maximise site up-time and efficiency metrics. 21
