1 Gaia-Wind Craig Jones Director, Business Development NSW Small Wind Industry Round-table Event: 15 Nov 2010

2 Since 1993; 260+ turbines installed 1000 years operational experience Class leading performance due to large rotor - 133sqm swept area in moderate winds m/s Paul Gipe s in Wind Energy Basics ; The wind turbine with the biggest rotor will almost invariably generate more power than a turbine with a smaller rotor; regardless of generator rating or purported efficiency Key customer groups - farmers, large homes, SME s and estates

3 UK FIT s have delivered large demand for good producing turbines To 6 turbines per week now, 10 per wk in 2011 Sales through key partnerships Well trained, limited number of wind/renewable experts

Control system activates mechanical brake 3.

4 The facts: 3 phase grid connected turbine G83 certification EN50438 Three levels of system protection; 1. Passive stall of blades 2. Control system activates mechanical brake 3. Centrifugally activated aerodynamic tip brakes Low noise; 40 db(a) at 100 m, rural night time background level; db(a), QUIET Turbine!

Towers; steel, hot dip galvanised Tubular or lattice 18m

7 Single piece, Glass fibre polyester Centrifugally activated tip brakes, manual reset Rubber bushings and teetering hub Towers; steel, hot dip galvanised Tubular or lattice 18m height, 15m lattice and 27m tube UK standard 100/120/140 foot USA standard

8 Manufactured by Mita-Teknik, Denmark Components: Computer Operation panel Capacitors Soft starter Contactors & fuses Voltage & current sensors Serial port for monitoring

9 Costs, typical; Gaia-Wind 11 kw turbine; fully installed Maintenance; 600 per turbine per year Revenues for typical kwh/yr FIT s 26.7p / kwh => 7,743 Savings on electricity bill; kwh x 15p => 2,100 Export; x 3p = 450 Total revenues; 10,293 Simple payback: 50,000 / (10, ) = 5.2 years!

10 Why Certify? Not a legal requirement globally but: Needed to access worldwide incentives Standardised method to compare turbines Normalised for tower height and altitude Declaration of yield AEP Peak / Rated power is a poor discriminator Wind speed / Power curve shape

11 Demonstration of safety and function End user assurance Confidence in durability 20 year life of UK incentive scheme Declares acoustic performance, useful for planning / permitting can be huge hurdle globally. Creates a high bar that discourages the Shysters and Bozos peddling their crud (Ackn. Mike Bergey, Bergey Wind Power Co. )

It is not a mechanism to police designs Declaration of changes are required but cert bodies not required to

12 It does not guarantee safety It judges the certified machine against the standard only. Very specific and clear cut. e.g. Aircraft engines are certified but occasionally fail. It is not a mechanism to police designs Declaration of changes are required but cert bodies not required to seek out any changes made. It does not guarantee performance just specs it.. Site specific It does not guarantee incentive eligibility. Scheme dependant

13 Testing began May 2008 in both USA (NREL) and UK (TUVNEL) Testing completed July 2010 Certification granted?? Over a 24 month cycle time.

Take 30 days at the test site for shakedown before beginning the formal testing.

14 Submit a machine which is design frozen and ready for testing. BoM has to be submitted. Take 30 days at the test site for shakedown before beginning the formal testing. Read the standards! It s time consuming and expensive. 24 months plus and c USD100k+. Treat it seriously and prepare carefully. Dialogue with certification body all the time.
