Constellation pours $180M into local economies during outages

Constellation Energy invested a combined $180 million during recent scheduled refueling and maintenance outages at its Limerick Clean Energy Center in Pottstown, Pennsylvania, and the Calvert Cliffs Nuclear Power Plant in Maryland. The projects brought roughly 2,900 skilled trade workers to the two regions and generated $5.6 million in local property taxes at Limerick in 2026.

Constellation completed a spring refueling and maintenance outage at Limerick in 2026, allocating about $90 million to the work. The project drew more than 1,400 specialized electricians, pipefitters and welders to the area. Limerick’s two boiling water reactors have a combined nameplate output of 2,317 megawatts and produce electricity sufficient for roughly 1.7 million homes.

In March 2026, Constellation finished a scheduled refueling outage at Calvert Cliffs that involved nearly $90 million in upgrades and near-term spending. That effort brought over 1,500 skilled workers to the site and focused on targeted facility improvements intended to keep the units running without interruption for the following 24 months.

According to Constellation, the work supported local hotels, restaurants and retail businesses while sustaining plant operations. Suppliers of lodging, food service and building materials reported higher demand while crews were on site.

Constellation operates the largest commercial nuclear reactor fleet in the United States. The company is a holding in the Range Nuclear Renaissance ETF (NUKZ), which tracks the VettaFi Nuclear Renaissance Index. Other listed holdings in the index include uranium producer Cameco, equipment and services firms such as GE Vernova and Rolls-Royce Holdings, and power companies including Talen Energy.

The company’s recent outages at Limerick and Calvert Cliffs combined $180 million in spending with the deployment of nearly 2,900 tradespeople during the scheduled maintenance periods.
