Iroquois is developing and permitting upgrades to its compression facilities in response to increasing demand for cleaner energy from fuel switching and economic growth. If successful, the Enhancement by Compression (ExC) project has the potential to optimize the Iroquois system to meet current and future gas supply needs of utility customers while minimizing environmental impact through compressor enhancements at existing compressor stations along the pipeline. The project’s total capacity is expected to be approximately 125,000 Dth/day with an estimated in-service date in November 2023. This project is underpinned by contracts for 20-year terms with local distribution companies.
