Introduction

SLIDE 3

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…

SLIDE 4

Why

SITE B

7.0 m/s
33.5% PLF

SITE A

6.5 m/s
29% PLF

Two sites, identical except for wind resource Huge additional value and profitability for Site B at no extra cost

SLIDE 5

Current Weakness

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

SLIDE 6

Current Weakness

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

SLIDE 7

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

SLIDE 8

A New Approach

Inputs Prevailing Winds

What is a perfect site?

Good exposure
Moderate terrain
Speedups
Ridges ∟ to wind
Highway Access
Grid Access
Land Availability

AND

Windy

SLIDE 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

SLIDE 18

Site Scoring

How Perfect is That Site?

SLIDE 19

Conclusion

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