Why do we need the Renewable

Energy Target?

Energy Target?

A few quick words about policy

5

History of the MRET

Howard’s original policy was very

successful- the 2% Target was reached in

2006. Growth in the industry greatly

reduced as REC price dropped as target

reached

www.suzlon.com6

In 2007 Kevin Rudd announced policy

plans for a second MRET- 20% of

electricity consumption by 2020 to

come from renewable energy

Why do we need the RET?

Why do we need the RET?

Without long term certainty and a

functioning incentive scheme, wind

farms will not be built.

farms will not be built.

This is why the RET is important to our

industry.

Three defined stages in the life of a wind farm:

• Development (3-5 years)

• Development (3-5 years)

• Construction (1½-3 years)

• Operation (+25 years )

Focus of the presentation is on construction and

operation

Foundations

Foundations

www.suzlon.com15

• Wind turbines require stable foundations at their base to hold them in

place to stop high winds from toppling them over.

• Suzlon S88 turbines weigh over 270 tonnes and stand 124 metres high to

the tip of the blade.

On-going operation and maintenance

• On going service and maintenance throughout the life of the farm

• 24/7 monitoring centre in Melbourne

• Economic stimulus for the region continues for the operational life of the infrastructure

Around the clock monitoring

Operation

• 25 year project lifespan typical for projects

• Wind turbine Power Performance Testing

• Post construction sound pressure level

• Usually a tech for each 7 turbines

• Community fund for the life of the project

• On-going environmental management of site

• Potential for turbine upgrades

Local benefits

Local benefits to wind farm projects exist and they are considerable.

JOBS:

-Specialist technicians

-Electricians

- Freight operators

- Machine operators

- General labourers

Other benefits:

-Community funds

-Landowner payments

- Stimulus of local industries

-Hospitality

-Accommodation

www.suzlon.com

Wind farms deliver much substantial than the

community benefits from coal/gas generation projects.

48

- General labourers

-Concrete businesses

-Engineering & Geotech

-Accommodation

-Equipment hire

- 4 wind farms 209 turbines ~440 MW

- Wind farming provided an annual increase of between

more than 1% each year to the region’s Gross Regional

Product over the approx 10 year project span
