IMPORTANT UPDATE: Like many companies throughout the world, electric utilities in the U.S. are seeing supply chain delays and material shortages stemming from the long-term impact of the COVID-19 pandemic. We are also experiencing these challenges. As a result, there are longer lead times for equipment required for new projects. It’s possible that these challenges may continue into late 2024.

While we are doing everything possible to mitigate the impact of these shortages, we are notifying customers to anticipate delays in new projects that require materials and equipment provided by ComEd.
