Effective Load Carrying Capability (ELCC) is a measure of a resource’s contribution to grid reliability, assessing how much additional load can be supported by integrating the resource into the grid. Measuring the contribution of variable and supply-limited resources to grid reliability is becoming increasingly important as such resources expand their role in the electricity grid. Several large system operators have recently adopted Effective Load Carrying Capability (ELCC) as an approach to measuring these contributions. ELCC measures a resource’s contribution to reliability based on the incremental quantity of load that can be satisfied by adding the resource to the grid. ELCC represents an important advance in calculating resource adequacy, as it better reflects the realities of how supply resources contribute to system reliability compared to previous methods.

We will soon publish our Capacity Watch for PJM report, which provides a comprehensive analysis of market drivers and recent developments, including Market Rules Changes for Capacity Accreditation (ELCC & CIFP), Increased Demand Forecast for Data Centers & AI and Retirement Drivers: At-risk assets driven by coal ash rules.
Ethan Howland reports in Utility Dive that after receiving two key Federal Energy Regulatory Commission decisions, the PJM Interconnection plans to hold its next capacity auction in June. Our Scott Niemann, Managing Director & Principal, said the FERC-approved changes will likely put upward pressure on capacity prices in most parts of PJM. Driven by pending power plant retirements, prices in PJM’s Southwest MAAC zone could break higher than the overall regional transmission organization.
ESAI Power’s recent Capacity Watch includes our forecast for the PJM BRA 2023/24. Our PJM analysis this quarter includes ESAI’s forecast for the PJM BRA 2023/24 and reflects upon MOPR, MSOC, ELCC and VRR Curves.
In ESAI’s latest Capacity Watch report, we analyze the three major rule changes that will impact pricing in the upcoming PJM Base Residual Auction (2023/24 BRA) and the subsequent influence on clearing prices out to 2030. These rule changes include FERC’s revised approval of ELCC, a default MSOC based upon Net ACR, and FERC’s failure to reach a majority decision on PJM’s proposed MOPR revisions.
