Project Description
Turning Sun Solar, formerly known as the Iyuhána Solar Project, is a 100 MW utility-scale solar development near Estevan, Saskatchewan. SaskPower identifies the project as the province’s first 100 MW solar facility and confirms that it was previously developed under the Iyuhána Solar name.
The project is being developed through a partnership between Greenwood Sustainable Infrastructure and Ocean Man Nakoda Nation. TULLOCH’s role has focused on geotechnical and foundation requirements for the solar array, providing field testing and preliminary engineering information to support foundation and detailed design.
Scope of Services
- Geotechnical investigations
- PV foundation design verification and load testing
- Preliminary helical pile foundation design
- Foundation performance assessment
- Engineering recommendations supporting detailed foundation design
- Topographic site surveys
