Effective Load Carrying Capability (ELCC) is measuring the contribution of variable and supply-limited resources to grid reliability, which 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.

PJM Set To Hold Capacity Auction In June After Receiving Mixed FERC Decisions | Capacity News

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.

PJM BRA 2023/24 Capacity Price Forecast | Capacity Watch Blog

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.

PJM BRA 2023/24 Rule Changes and Auction Parameters: Capacity Price Forecast | Capacity Watch Blog

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.
