Constellation Energy CEG benefits from its expanded generation fleet, strengthening its ability to meet rising demand for reliable electricity. Following its January 2026 acquisition of Calpine, CEG uses the Equivalent Forced Outage Factor (EFOF) to measure forced outages and reduced operating capacity across its natural gas, oil and pumped-storage hydro fleet.
CEG’s EFOF increased to 6.2% in the second quarter of 2026 from 4.5% in the first quarter. The higher EFOF indicates greater forced unavailability or reduced operating capacity across the applicable fleet. The metric covers multiple generation technologies, so the 6.2% figure should be viewed as a combined fleet measure rather than compared directly with benchmarks for a single plant technology.
Reducing EFOF could improve fleet availability and enable the company to capture more opportunities from its expanded generation portfolio. This is particularly relevant as CEG integrates the larger generation portfolio acquired through Calpine. Improving reliability and reducing forced outages could help the company maintain greater availability across its gas, oil and pumped-storage hydro assets.
CEG reported a 93% nuclear capacity factor in the second quarter of 2026, excluding Salem and South Texas Project, along with a 96% renewable energy capture rate, highlighting performance across its nuclear and renewable generation fleets.
Thus, lower EFOF, alongside strong nuclear and renewable performance, could improve fleet availability, supporting power sales, capacity revenues, operating efficiency and cash flow.
Fleet Performance Monitoring Aids Utility Growth
Fleet performance monitoring helps utilities track asset health, identify emerging failures, optimize maintenance and improve reliability. Data-driven insights can reduce downtime and operating costs while supporting efficient asset utilization, stronger performance and sustainable utility growth.
Clearway Energy, Inc. CWEN tracks fleet performance through plant availability, with solar at 99%, flexible generation at 97% and wind at 92%, alongside compensable generation and performance indices.
Vistra Corporation VST reported 95.7% total commercial availability and 50.2 terawatt-hours of generation, reflecting strong operational availability and effective utilization across its power-generation fleet.
