Enbridge Gas Kingston

At a Glance
• System Configuration: 2 × C65 Off-Grid Standalone Capstone Microturbines with BAS controls integration
• Thermal Output: 860,000 BTU/hr of recovered hot water for facility heating


The Challenge
Enbridge Gas is the leading distributor of pipeline-grade natural gas across Southern Ontario, distributing over 6 billion cubic feet of natural gas daily and serving roughly 75% of Ontario residents. Managing critical regional gas transmission infrastructure requires maximum operational continuity, especially in strategically vital hubs like Kingston. For this facility, reliance on the local electrical grid was not an option. Enbridge required an entirely off-grid, islanded power and thermal plant capable of delivering continuous, highly reliable electricity and space heating without external utility dependencies.


The Solution
The 130 kW standalone microturbine energy plant at Enbridge Gas’s Kingston facility is engineered to operate completely disconnected from the local electrical power grid, fully integrated into the site's building automation system.
• 100% Off-Grid Standalone Power: Delivers continuous, independent electricity to power critical utility operations without relying on the local electrical distribution grid.
• Thermal Exhaust Heat Recovery: Captures microturbine exhaust to generate 860,000 BTU/hr of hot water, supplying efficient facility space heating during cold weather.
• Building Automation System Integration: Fully connected into local BAS controls to automate system balance and optimize performance against operational loads.
• High-Reliability Air-Bearing Design: Utilizes single-moving-part turbine technology, eliminating oil, liquid coolants, and traditional high-wear mechanical components to ensure maximum uptime in an isolated setup.


The Results
• Complete Energy Resiliency: Operates fully off-grid, shielding critical utility operations from regional grid instability, severe weather outages, and peak utility pricing.
• High-Efficiency Heat Recovery: Recovers waste exhaust heat for building thermal demands, maximizing fuel utilization and reducing overall site emissions.
• Validated Utility-Grade Trust: Successfully completes Project 2 of Enbridge Gas's multi-site deployment alongside the Burlington installation, highlighting long-term confidence in microturbine technology.
• Low-Maintenance Operation: Demonstrates how localized natural gas generation provides clean, quiet, and low-maintenance baseload power for critical energy infrastructure.
