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

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 cost- effective technical services to wind farm developers.

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

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

Current Weakness Wind Map Accuracy: >0.5m/s @ 50% sites Insufficient alone

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

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

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

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

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

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

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

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

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

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

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 Map of Buildable Areas • Neighbouring Wind Farms > 5km

Site Scoring How Perfect is That Site?

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