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.
