Why is international and inter-regional collaboration crucial for cross-border transmission project?

Interregional coordination is even more effective when integrated into grid design from the outset. A US study using a co-optimised capacity-planning and dispatch model found that interstate coordination in a 100 percent renewable system could reduce electricity costs by 46 percent — going from USD 135/MWh in a state-by-state approach down to USD 73/MWh with a regional strategy. While many regions outside the US already embrace interconnection, proactive planning of a coordinated grid can further enhance cost savings and efficiency.

Collaboration fosters shared risk, improved decision-making and greater adaptability in transmission projects. As the sector moves toward net-zero goals, flexible and cooperative delivery models are essential to navigating unforeseen challenges.

The Convertus Group (Convertus) York Biofuel Facility is set to become the largest biofuels project in Canadian history — a CAD 490 million initiative over a 20-year operating period that will produce renewable natural gas and fertiliser and reduce greenhouse gas emissions by up to 15,000 tonnes annually.

The project showcases a successful collaboration between GHD and Convertus, delivered using Integrated Project Delivery (IPD) with Bird Construction (Bird). GHD originated the project with Convertus, led the permitting process and is delivering the balance of plant design work. Through a truly collaborative approach, Convertus, GHD and Bird each play a key part in the project’s success, while transparently managing scope, schedule, budget and risk.

GHD’s Project Manager Ryan Loveday reports there have been improved project outcomes across the board, both on the delivery and project side, as well as from project team members involved in the lean and agile process. Convertus, Canada’s largest organic waste processor, will operate the facility under a 20-year contract with the Region of York.

Designed for long-term sustainability, the plant will be solar-ready, capture stormwater for reuse and feature advanced odour control through a photoionisation system. The captured biogas will be upgraded and injected into the natural gas grid. Digestate will also be treated and then used as fertiliser.
