Central East Transfer Out (CETO) Project Update
As Alberta's energy landscape continues to evolve, it's crucial to invest in projects that address our province's changing energy needs while enabling a modernized system that can readily accommodate renewable generation. One project we are incredibly proud of is the Central East Transfer Out (CETO) project.
This initiative is a testament to our commitment to identifying future energy requirements and advocating for the infrastructure that will support Alberta's prosperity. Our teams are now well into the construction phase of this project, marking a significant milestone that reflects years of planning and dedication. The CETO project is designed to enhance Alberta's energy infrastructure.
Paving the Way for Alberta's Energy Needs:
ATCO's CETO Project Construction Well Underway
The global energy landscape is expanding and evolving, and Alberta is no exception. As our province’s population increases, so do our energy needs. Albertans need more power, and we are working to meet that demand by finding new ways forward that address the energy demands of our growing economy while enabling a modernized system that can more readily accommodate renewable generation.
What is the CETO Project?
The Central East Transfer Out (CETO) project is an important initiative to strengthen Alberta's energy infrastructure at a critical time. With the existing transmission system in the central east region nearing its capacity limits, the Alberta Electric System Operator (AESO) has identified the CETO project as essential for integrating additional renewable energy sources and enhancing the reliability of the transmission system. ATCO is addressing this need by reinforcing and upgrading the infrastructure in their service area and is thrilled to see the first season of the construction phase nearing completion.
The CETO project will consist of 135 km of double circuit 240-kilovolt transmission connections and alterations to existing substations. ATCO’s portion includes 240kV, 85 kilometers of double circuit transmission lines and the expansion of the Tinchebray 972S substation.
In 2024, significant preparations were made for the construction phase of this project. During the spring and summer, our distribution teams in Stettler, Alberta, laid the groundwork for the upcoming CETO project by completing all the distribution line moves and crossings. This ensured a smooth transition into the transmission line construction phase. In October and November 2024, early-stage construction began as the monopoles arrived on site. From December to now, we have made tremendous progress, with construction for this phase expected to be complete by spring 2025, with 50% of the line completed by the end of season 1. The next construction phase is planned for winter 2025/2026.
The construction of the line involved using high-performance overhead power line conductors with superior strength and resilience to ensure reliable performance in severe environmental conditions. By integrating additional renewable generation and improving transmission system reliability, we are ensuring a resilient and dependable energy supply for the province's growing population and economy. Reaching the construction phase of this project is a significant milestone, reflecting years of planning and dedication.
A VISION FOR THE FUTURE
The Central East Transfer Out project will enhance the capabilities of our infrastructure, enabling a modernized system that can more readily accommodate renewable generation projects. Projects like CETO expand the grid to enable economic prosperity in Alberta by connecting new generations and expanding capabilities to serve new and existing customers.
The success of this project is made possible by the contributions of our major contractors: Midal, Valmont, Paradox, Site Reg, AECON, and Victor Energy. A huge thank you to AltaLink for their collaboration, which has been instrumental in ensuring synergy between the two Transmission Facility Operators building parts of the CETO line. The dedication, hard work, and collaboration of everyone involved have been essential in bringing this project to life.
