The state-owned utility, PT Perusahaan Listrik Negara (PLN), signed the letter of intent with developer Total Eren ahead of the One Planet Summit taking place in France, designed to "promote tangible means to achieve the Paris Agreement".
The 70MW Tanah Laut project will be build in Kalimantan, the Indonesian' part of the island of Borneo in south-east Asia.
Total Eren said its local subsidiary Pace Energy, has conducted a wind resource assessment of the proposed site over 20 months, which confirmed it was a "high-quality" project location.
GE's local subsidiary, GE Indonesia, will partner the project as technology supplier and has supported the project design and carried out the grid connection study, Total Eren said.
French conventional power player Total acquired a 23% stake in compatriot Eren RE in a €237.5 million deal in September. Under the terms of the deal, Total will have the option to take full control of Eren RE after five years.
Eren RE had roughly 650MW of wind, solar and hydro projects in operation or under construction across the world at the time of the acquisition.
