Castle Rock Bridge Wind Farm

Castle Rock Ridge Wind Farms

Soaring vistas, snow-capped peaks – the dramatic Alberta landscape is legendary. But it offers more than scenic views alone: the mighty ridge of the Rockies that courses through the province generates a forceful wind. At the Castle Rock Ridge I & II and Riverview wind farms in Pincher Creek, Alberta – our northernmost plants in the Western Hemisphere – we’re harnessing that power to generate sustainable value for our host communities.

The project

Harnessing the power of Alberta

Located in the Town of Pincher Creek, Alberta, the Castle Rock Ridge I & II wind farms generate enough wind power to meet the needs of over 27,000 Canadian households each year. Castle Rock Ridge I began operating in 2012 as Enel Green Power’s first entry into Alberta, with 33 turbines representing 76.2 MW of capacity. In 2020, the company began operating Castle Rock Ridge II, a 29.4 MW project that will supply its net power output and renewable energy credits to the Alberta Electric System Operator. A third wind farm, Riverview, also came online in Pincher Creek this year.

Our Corporate Partners

Castle Rock Ridge II – along with another Enel Green Power wind farm in Pincher Creek, Riverview – is generating sustainable power for Albertans. The project will supply its net power output and renewable energy credits to the Alberta Electric System Operator (“AESO”) under two 20-year Renewable Energy Support Agreements (“RESAs”), awarded in 2017 through a tender launched by AESO.

Community Impact

Enel Green Power is committed to creating long-term shared value for its host communities and supports critical initiatives in the Pincher Creek area. Enel has supported community needs such as the wind energy education program at Lethbridge College and the Pincher Creek Maker Centre, a youth-led facility for the development of skills and capabilities in art, design, coding, robotics and other technical areas.  Additionally, Enel Green Power has fostered relationships with the Piikani Nation to further Indigenous economic reconciliation. During the COVID-19 pandemic, Enel committed additional funds to the Town of Pincher Creek Family and Community Support Services and the Piikani Nation Emergency Package for local businesses and food security services.


“It’s really cool to have [Enel] here and not just be the name on the side of the wind turbine but be invested in the community. And seeing that industry is invested in us as youth is really empowering.” 

Dalton Bonertz, Secretary of Pincher Creek Trailbreakers Club, Matthew Halton High School
