The plan, in PLTB Tolo-I will be installed 20 wind turbines with each capacity of 3.6 Megawatts (MW), so the total capacity of the plant reaches 72 MW. No less than 60 propellers will be shipped to the project site until the end of April 2018.

The turbine model installed in this PLTB uses Siemens DD On-Shore 3.6 WTG where 2 units of Siemens transformers are installed with capacity of 45 MVA each.

Currently, PLTB works with an investment of USD 160.7 million has entered the stage of installation of towers and turbines. Day after day, strategic projects of PLTB development are continuously accelerated. Until February 23, 2018, the overall progress of the project reached about 65%.

PLTB Tolo-I is generated from a wind speed of 6 m / s which is a large enough wind potential to be developed commercially. The Power Purchase Agreement (PPA) signed by the State Electric Company with PT. Jeneponto Bayu Energy from November 14, 2016 with electricity selling price of US $ 10.89 cent / kWh.

Based on the PPA, the project will be completed and the Commercial Operation Date (COD) on November 14, 2019. The presence of PLTB Tolo-I Jeneponto will complement the presence of Sidrap PLTB to increase the contribution of wind-based energy in Indonesia, in addition to increasing the reliability of electricity in South Sulawesi, this electrification ratio has reached 99.12%.
