A recent PJM interconnection assessment gave the submission for a planned FuelCell Energy Block system a 99.873% rating through PJM’s unit-specific Effective Load Carrying Capability (ELCC) process. In plain terms, that means PJM may count almost all of a 100 MW FuelCell Energy system as dependable capacity—about 99.9 MW—when evaluating resources available to support grid reliability in the 2028/29 Reliability Backstop Procurement auction. Project owners and operators can strengthen project economics when PJM recognizes more of their installed capacity as dependable and eligible for capacity-market value.

1 FuelCell Energy unit-specific PJM ELCC RBP assessment for the 99.873% rating
2Preliminary ELCC Class Ratings For Use in the Reliability Procurement Backstop (RBP)
The unit-specific value was calculated using assumptions specific to 2028/2029 Base Residual Auction. Any future calculations for subsequent auctions with updated assumptions may result in a different value.
Effective Load Carrying Capability, or ELCC, is a methodology used by PJM to assess the reliability contribution of different power resources. Rather than focusing solely on nameplate capacity, ELCC evaluates how likely a resource is to perform during critical grid conditions.
As the power mix evolves and includes more intermittent resources, ELCC has become an increasingly important measure of reliability. Resources, such as FuelCell Energy’s patented technology, that can consistently deliver power during periods of peak system stress generally receive higher accreditation values, while resources whose output is dependent on weather or limited-duration energy storage may receive lower ratings. In simple terms, ELCC reflects how much of a resource's capacity PJM believes can be counted on when reliability is most critical.
Data centers require around-the-clock electricity. FuelCell Energy's carbonate fuel cell technology is designed to provide continuous, dispatchable power independent of weather conditions. A high ELCC rating reflects the value of that operational reliability.
In regions served by PJM, accredited capacity can play a meaningful role in project economics. Resources that receive higher capacity accreditation may provide greater value than technologies with lower ELCC ratings because more of their installed capacity is recognized by the market.
As developers seek ways to accelerate project timelines, on-site generation can help address challenges related to transmission availability and interconnection delays. FuelCell Energy's modular technology provides a scalable solution that can be deployed closer to load while supporting both energy resilience and grid reliability.
For data center operators evaluating energy solutions, reliability is increasingly becoming a competitive advantage. PJM's unit-specific ELCC assessment provides an independent benchmark demonstrating the capacity value of FuelCell Energy's technology within one of the country's most sophisticated electricity markets.
