Course context
Current and future industry requirements
Key Stakeholders
Office of the Renewable Energy Regulator
• Small scale Renewable Energy Scheme
• Large scale Renewable Energy Target
• Green Power
Clean Energy Council
• Accredits small scale renewable energy installers (majority PV)
• Peak body for Australian renewable energy businesses
• Developing approved product list, considering wind standards
• Intend to require small wind installers to undertake this course
• Responsible for Electrotechnology Training packages
• Wind competencies (Currently three units) are part of UEE07 TP
• This course identified to fill gaps in current Training Packages
Office of the Renewable Energy
Regulator requirements
•That all Small Generator Units are
installed by Clean Energy Council
accredited installers to be able to claim
deemed STCs
•As of December 2010 this includes small
scale wind (up to 10kW)
Slide 12
Clean Energy Council requirements
• $5M public liability insurance (Australian)
• Be bound by, and comply with, the CEC Code of Conduct in
the installation of the SGU
• Ensure that the installation has all applicable local and
state/territory Government approval requirements
• Ensure that the SGU and its installation, including wiring,
meets relevant Australian and International Standards, and
that key components are listed on the Clean Energy
Council’s list of approved products.
Slide 13
Clean Energy Council requirements
• Ensure that the mounting and orientation of the
SGU are in line with the Clean Energy Council
accreditation requirements.
• Supply all relevant documentation to certify correct
installation of the SGU.
• Comply with the Regulated requirements for
installation of the SGU, by signing suitable
compliance paperwork.
• Hold relevant EE-Oz units of competency to design
and install small wind turbines
Slide 14
EE-Oz requirements
•UEE07 Training Package
Install small wind energy conversion systems for
stand-alone applications
Solve basic problems in wind energy conversion
Design wind energy conversion systems up to 10kW
Each have a number of different prerequisites
•UEE11 Training Package coming soon

Slide 23
Small Wind Site Assessment Process
1. Understand the customer
•Customer’s expectations for and knowledge of wind
•Energy consumption and economic situation
2. Assess the site: desktop study
•Land use, location, size, ownership
•Elevation, topography, obstructions
3. Evaluate the site: site visit
•Turbulence and ground drag, tower considerations
•Grid connection, cable run, ground conditions
4. Estimate the energy resource
•Identify wind data and information sources
•Displacement height, alpha and turbulence
5. Investigate other constraints
•Zoning, neighbours, environmental conditions
•Connection requirements, flight paths, protected areas
6. Determine system options
•Tower type and minimum height, turbine options
•Estimate energy production
7. Do site assessment report
•Site diagram, aerials and topographics, wind maps
•Energy yield and financial performance

Example Reports
Slide 28
• Site assessments are a lot of work,
• And are not an exact science, but…
• Lead to thoroughly and properly considered sites
• Presentation of findings in an independent report
• Client makes informed decision, which leads to turbines
performing as expected (usually)

• Divide into four groups
• List as many answers as you can to
question one (3 mins limit)
• List as many answers as you can to
question two (3 mins limit)
• Compare answer and score like
