Electricity consumption in Universiti Tun Hussein Onn Malaysia (UTHM) has previously been forecasted using a time series model, fuzzy time series (FTS) and multiple linear regression (MLR). Even though FTS gives the best prediction among these methods, the manual implementation of FTS can be a time consuming and laborious process. Like FTS, Fuzzy inference system (FIS) is an alternative system that utilizes fuzzy logic concept. The prediction using FIS, however, required multivariate data such as day, time, temperature, humidity and historical consumption data as its input. In this study, monthly univariate data of UTHM electricity consumption from January 2009 to December 2018 was employed for the forecasting of electricity consumption for the year 2019. FIS was chosen to be compared with the FTS method. Historical univariate data were fuzzified using trapezoidal rule following the FTS method before Sugeno type FIS was chosen to give constant output. A simple fuzzy rule was applied to map the input to output. 2.3173% of mean absolute percentage error (MAPE) was obtained in FIS which is considerably low if compared to the time series model (11.14%), MLR (10.62%), and FTS (5.74%).
