Ohorayama Wind

Shikoku, Kochi

Ohorayama Wind is located on the southern part of the island of Shikoku in Kochi Prefecture. The facility is built on a forested ridgeline currently used for industrial purposes. By combining both renewable energy production and lumber, GPI and Pattern Energy are focused on maximizing results while minimizing land use.

Creating lasting, meaningful relationships is innate to Japanese culture and an essential component of each of our projects. Members of our team often live in the areas where our facilities are operating and engage with landowners, local leaders, and the community.

The Shikoku community is highly supportive of Ohorayama Wind, which brought in approximately 100 construction jobs and utilized local vendors. 8–12 full-time positions are also required to maintain the facility.

We are committed to protecting the environment and conserving natural resources.

In Japan, environmental impact assessments take multiple years and involve a specialist with expertise in the local environment who is often from the project community.

We believe Japan has tremendous potential for growth in renewable energy.

We continue harmonizing our strengths and collaborating on best practices while respecting traditions and cultural norms.
