Abstract	Tenaga Nasional Berhad (TNB) power plant gas turbines fuel is supplied by PETRONAS through Peninsular Gas Utilization (PGU) pipeline system. In May 2013, PETRONAS started to inject Liquefied Natural Gas (LNG) into PGU to meet the agreed gas fuel energy supply volume. The main objective of this research is to find out the effects of the changes in gas fuel quality being supplied into TNB owned power plant, namely Tuanku Jaafar Power Station (TJPS), before and after the LNG injection into the PGU in 2013. This research is conducted to determine whether the new gas fuel quality still conforms to gas supply agreement (GSA) and the Original Equipment Manufacturer (OEM) specifications, and to study the impact of the LNG injection to the station's gas turbine performances. LNG is imported from different sources all over the world. Different sources produce different gas quality, hence could cause significant swings of gas quality in the pipeline. This may affects TJPS gas turbines (GTs) performances in terms of output, emissions and operations. The gas quality data from daily PETRONAS Gas Billing Invoices from 2008 to 2014 are used to calculate the Wobbe Index (WI), Gas Index and Modified Wobbe Index (MWI) of the gas for TJPS Mitsubishi Heavy Industries (MHI) GTs and General Electric (GE) GTs respectively, and compare the values to the OEM's recommended operating range. LNG injection has introduced variations to WI, GI and MWI but the quality of the gases are found still within the specified limits.
