Shell WindEnergy Inc. is involved in developing wind power projects in both the U.S. and Europe. In the U.S., it has 8 projects totaling 900 MW of capacity, and in Europe it has 3 projects totaling 200 MW. One project discussed in more detail is the proposed Wild Steer Butte wind farm in Alberta, Canada, which could generate up to 775 MW and is dependent on transmission infrastructure upgrades. While Alberta has significant wind power potential due to its deregulated electricity market and carbon offset programs, the industry faces economic challenges due to low power prices and a lack of long-term contracts or government incentives.

5. Wind in Alberta
Market design
— Merchant market
— One of the most deregulated markets in North America
Climate Change Legislation
— Functioning carbon offset market
Generation capacity
— 13,447 MW existing generation, 805 MW of which is wind
Interconnection queue
— >12,000 MW of projects known, about 5,700 MW of which is advanced enough to be in the queue
— Almost 7,000 MW of wind projects known, about 3,400 MW of which is in the queue
Transmission
— Southern Alberta Transmission System (SATR) being built to accommodate 2,700 MW of wind
— Load pays for transmission build

6. Wind in Alberta - Challenges
Economics
— Few long term Power Purchase Agreements (PPA)
— Low power prices
— No federal or provincial incentives
Climate Change Legislation
— Canadian government has stated intention to follow US lead
— Uncertainty on future of Alberta system and future price
