I ka mākeke generator, ʻo nā ʻoihana hana e like me ka aila a me ke kinoea, nā ʻoihana lawelawe aupuni, nā ʻoihana, a me nā mining i hiki ke ulu i ka mākeke.Ua manaʻo ʻia e hiki i ka mana mana o ka ʻoihana hana ke hiki i 201,847MW i 2020, e helu ana no 70% o ka nui o ka mana o ka mana o ka hana ʻana i nā ʻāpana.

Ma muli o ke ʻano o ka ʻoihana hana, i ka wā e ʻoki ʻia ai ka mana, e pau ka hana o nā mea hana nui a i ʻole e hōʻino ʻia, no laila e hoʻopau ai i nā poho waiwai.ʻO nā ʻaila hinu, ka ʻaila a me ka ʻili mineral, nā mana mana a me nā ʻoihana ʻē aʻe, i ka wā e kū ana me ka hoʻopau ʻana o ka mana lako, e hoʻopilikia koʻikoʻi i ka hana maʻamau o nā kahua hana ʻoihana.ʻO ka generator set kahi koho hilinaʻi o ka mana hoʻihoʻi i kēia manawa.

No nā makahiki he 10, ua hāʻawi ʻo GTL i ka hōʻoia mana no nā ʻoihana hana he nui a puni ka honua.Ke hilinaʻi nei i ka ʻōnaehana hui pūnaewele a me ka Pūnaewele o nā mea, ua hiki mai ka ʻoihana 4.0.Ke manaʻoʻiʻo nei i ka wā e hiki mai ana o ka hoʻomohala ʻana i ka naʻauao ʻoihana, e hāʻawi nā huahana GTL i ke kākoʻo hou aku no ka palekana ʻike ʻike a me ka pale.
