2 Introduction Wind Pioneers is a new venture with a new business model to bring highly innovative, flexible and costeffective technical services to wind farm developers.

3 Introduction Wind analyses from site finding to energy assessments Wind Pioneers is a new venture with a new business model to bring highly innovative, flexible and costeffective technical services to wind farm developers.

4 Why Two sites, identical except for wind resource SITE A 6.5 m/s 29% PLF SITE B 7.0 m/s 33.5% PLF Huge additional value and profitability for Site B at no extra cost

5 Current Weakness Map predicts highest wind in shadow of mountain Highest wind will be at top of mountain

6 Current Weakness Wind Map Accuracy: 50% sites Insufficient alone

7 A New Approach STEP 1 Characterise a perfect site STEP 2 Find sites matching characterisation

8 A New Approach What is a perfect site? Inputs Good exposure Moderate terrain Speedups Ridges to wind Highway Access Grid Access Land Availability Prevailing Winds AND Windy

9 Good Exposure What is a perfect site? Good exposure Moderate terrain Speedups Ridges to wind Highway Access Grid Access Land Availability AND Windy Distance to higher land

10 Moderate Terrain What is a perfect site? Good exposure Moderate terrain Speedups Ridges to wind Highway Access Grid Access Land Availability Slopes > 17 AND Windy

11 Speedups What is a perfect site? Good exposure Moderate terrain Speedups Ridges to wind Highway Access Grid Access Land Availability Height gain AND Windy

12 Ridges to Wind What is a perfect site? Good exposure Moderate terrain Speedups Ridges to wind Highway Access Grid Access Land Availability AND Windy Wind roses

13 Highway Access What is a perfect site? Good exposure Moderate terrain Speedups Ridges to wind Highway Access Grid Access Land Availability AND Windy Distance to Roads

14 Grid Access What is a perfect site? Good exposure Moderate terrain Speedups Ridges to wind Highway Access Grid Access Land Availability Closest Substation AND Windy

15 Land Availability What is a perfect site? Good exposure Moderate terrain Speedups Ridges to wind Highway Access Grid Access Land Availability Protected Forest AND Windy

16 Windy What is a perfect site? Good exposure Moderate terrain Speedups Ridges to wind Highway Access Grid Access Land Availability Combine multiple meso maps to reduce errors + AND Windy

17 Multiple Development Constraints Highway < 20km Rivers > 1km Terrain < 20 deg slope National Parks excluded Forestry excluded Agricultural land use Within 1 province Airports > 20km Substations < 20 km Urban Areas > 10km Habitations > 1km Neighbouring Wind Farms > 5km Map of Buildable Areas

18 Site Scoring How Perfect is That Site?

19 Conclusion Find better sites Find different sites to your competitors Save costs on unviable sites
