We focus on providing safe, reliable and competitive natural gas transportation to meet our customer's needs and bring on additional capacity to meet growing demand. We believe the significant widening of regional price spreads to other North American markets is driven by an abundance of low-cost, competitive WCSB supply relative to market pricing and pipeline capacity to those markets. The solution is to build for firm service and efficiently advance projects that support additional capacity to markets, enhance system redundancy, or both.
We are working to provide increased capacity and market access through our multi-billion dollar expansion program. We anticipate bringing on an additional 1.3 Bcf/d of capacity in 2022, with our current capital program adding an additional 2.2 Bcf/d between 2023 and 2026. However, we have and continue to face growing external challenges to complete our expansions on time, from weather and labour shortages, to increasing environmental and regulatory requirements, as well as regulatory and government delays in approvals.
While localized constraints during periods of maintenance related outages can cause daily or short-term price volatility, we believe the significant widening of regional price spreads to other North American markets is driven by supply imbalance.
Conducting maintenance is an integral part of ensuring the safe and reliable operations of the system. This is important to our customers and stakeholders just as it's important to us, and we will continue to work with them to ensure we complete this important work while mitigating impacts whenever possible.
All planned maintenance outages are closely coordinated with our customers and communicated to industry months in advance. Summer 2022 outages were initially communicated to customers in January and discussed at our monthly operational meetings. In the case of an unplanned outage, we strive to give the best information we have as promptly as possible.
