Reliability performance is core to the utility industry. Utilities strategically design and invest in their system to maximize reliability performance—traditionally measured by System Average Interruption Frequency Index (SAIFI), System Average Interruption Duration Index (SAIDI), and/or Consumer Average Interruption Duration Index (CAIDI). These quantitative metrics largely drive utility investment decisions, shape strategic priorities, dictate regulatory approvals, […]

At the virtual 2nd Global Ministerial Conference on System Integration of Renewables on Oct. 27, several high-ranking policymakers pointed to a number of localized challenges affecting their countries’
