The Program is a joint initiative between the NSW Office of Environment and Heritage (OEH) and Department of Education and Training NSW. It is part of the NSW Government’s $150 million Energy Efficiency Strategy. Visit savepower.nsw.gov.au Slide 4 Introduction Who are we? Who are you? Ground rules and expectations • phones and laptops • attendance • questions and discussion anytime Slide 5 Workshop Overview and Timeline Start and end times Lunch, and breaks (Please let us know if you need a break!) Bathrooms Survey today before morning tea Brief topic feedback forms Slide 6 Pre-course survey results • Previous training in small wind site assessments? o a quarter • Level of awareness of effective ways to conduct small wind turbine site assessments? o 2 – somewhat aware • Do you currently conduct small wind site assessments?: o a quarter • Primary reasons for attending: o o o o Knowledge/skills/rigour/efficiency/tools for site assessment process Learn more about wind resource assessment Industry standards/technical information CEC accreditation Slide 7 Workshop Materials Learner Guide • • • • course outline powerpoint presentations reference materials site assessment template Expect handouts as we go, and possible updates in future as we refine the course after this pilot You’ll need it each day of the course You get to keep it so scribble away Slide 8 House keeping • Sign-in sheet • Do we have your consent forms? Slide 9 Small wind site assessment course 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 EE-Oz • 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 11 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 systems Design wind energy conversion systems up to 10kW Each have a number of different prerequisites •UEE11 Training Package coming soon Slide 15 Small wind site assessment course: What is a “small wind site assessment”? Purpose Systematically investigate a site for the suitability of a small wind system Allow a client to make an informed decision Slide 17 Approaches 1. The wet finger approach 1. Gather wind speed data and check for the distance to the airport 1. Systematic investigation of the important considerations Slide 18 Approach and Documentation 1. The wet finger approach 1. Quote 1. Gather wind speed data 1. One page summary of wind speed and expected wind turbine performance 1. Systematic investigation 1. Independent site report for client Slide 19 Documentation and Risk 1. Quote 1. One page summary 1. Independent site report for client High risk: underperforming system and potentially harmful to the industry Not an exact science but the risk is significantly reduced Slide 20 Audience for report • • • • • • • Homeowner or potential client Installer Small scale technology certificates (STCs) Permitting and zoning Lending agency Neighbours Perhaps an attorney representing an irate neighbour Slide 21 Site Assessment Trends Midwest Renewable Energy Association (MREA) Site Assessment Trends North American Board of Certified Energy Practitioners (NABCEP) 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 Tools for Site Assessment Report Template Supplement Examples Slide 25 Site Assessment Template Slide 26 Site Assessment Supplement 1. Wind basics 2. Turbulence/terrain 3. Wind system siting considerations 4. Wind resources 5. System towers 6. Minimum tower height 7. Turbine types 8. Economics/costs 9. NSW small wind planning provisions Slide 27 Example Reports Slide 28 Outcomes • 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) Slide 29 Small wind site assessment course Why buy a wind turbine? Understanding customer motivations Why buy a wind turbine? • 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 Scattergories Slide 31
