This paper discusses short-term peak load forecasting for the South Sulawesi system (Sulbagsel), Indonesia. The peak load is forecasted using interval type-2 fuzzy logic (IT2FL) combined with the horse herd optimization algorithm (HHOA). The HHOA method is employed to optimize the footprint of uncertainty (FOU) in fuzzy logic, including both the antecedent (X, Y) and the consequent (Z). This approach is applied using daily peak load data from the four days prior to the forecasted day (d-4) and the forecasted day itself (d). To compare the HHOA method, similar swarm intelligence techniques, the cuckoo search algorithm (CSA) and Bat Algorithm (BA), are also used. The test results show that IT2FL-HHOA provides more accurate forecasting, as indicated by a significantly lower mean absolute percentage error (MAPE). The MAPE for IT2FL-HHOA is 1.5567%, while for IT2FL-CSA, it is 1.6289%, and for IT2FL-BA, it is 1.6386%. For the Type-1 fuzzy logic (IT1FL-HHOA) method, the MAPE is 1.6604%, for IT1FL-CSA it is 1.6730%, and for IT1FL-BA it is 1.6704%. © (2025), (Intelligent Network and Systems Society).
