    In some cases shielding of harmonics generated in system is done by GT. Voltage regulation is also required by using OLTC of GT. I have seen Industrial system useing 415V as generator output voltage and directly connected to load through LV switchgear.For example, DG set used in Jute industry. But the criteria is again harmonics which is also mitigated by using filtering circuts. Also one poing if load center is near to generating station LV generator can also be selected. In a nutshell its Techno-economic consideration for selecting GT.
