54.8 MW Under Development Stages
We believe this is one of the most crucial stages in project executions. Every projects at this stage undergone a rigorous study and checking. We believe it is important to get it right the first time before the construction work is done. Taking all the necessary data in developing our sites is required. We take pride in the high-level sophisticated capabililties of our Engineering team. We understand that good quality design take times and require substantial amount of investment in developing complex projects such as Hydro Power. Apart from the technical stand point, our company also develop projects so the most significant community development is done. We love our earth, we love our people and we help the community around us to grow.
Below is some of our projects under development:
The Tomoni MHPP Project is a proposed run-of-river hydroelectric power generating facility. It is located at the South Sulawesi Province. Upstream of the MHPP are protected forest, which will give a better flow continuity.
Future minimum capacity of the power plant is 2 x 5 MW coming from two Francis turbines with head and discharge of 96.5 meters and 11.91 m³/sec. Weir elevation is 251.5 meters above sea level. Water will flow through two intake gates then into the desedimentation basin to diminish its coarse sediment content. Waterway consist of a 500 meters open channel and 1200 meters of tunnel. Water then flows into a forebay tank to ensure a good continuity in operation in case there are operational load change and also to diminish the probability of vortex in the inlet of the 365 long penstock. Tailrace water level is at 154 meter above sea level.
The Basic design for Tomoni MHPP is already done and currently under geological investigation for the tunnel scheme. The construction start is planned on Second Half of 2015.
Padalembara MHPP, is located at Central Sulawesi province. It is an interesting run-of-river hydroelectric power generating facility. The proposed Power Plant consist of two schemes coming from two different rivers that flow into a junction, Mao River and Takoraru River. The two schemes of hydro power plant will unite into a single forebay tank. From the forebay tank water will be conveyed through a 1,500 meter long penstock. The Power output is approximately 9.1 MW, coming from a 2.7 m³/sec discharge and the net head of 400 meter.
Salondo MHPP is located at South East Sulawesi province. Majority of Olooloho MHPP watershed area are protected forests. Power output of the plant is 6.1 MW. The power is derived from 4 m³/sec of discharge and the net head of 175 meter.
Crest of diversion weir is at 480 meters above sea level, the diverted water then flows through the intake and the water is sediment content is lowered at the desedimentation basin. Then a 2400 meter long open channel is used to convey water from Desedimentation basin to the Forebay tank. Penstock length is 350 meter.
The projects is currently under Detail Design stage.
Ranteangin MHPP is located at South East Sulawesi, just about 90 kilometers south of the Olooloho MHPP. Ranteangin MHPP is a unique run-of-river hydroelectric power generating facility. Ranteangin MHPP consists of two schemes coming from two different rivers that flows into a junction. The two schemes of hydro power plant will unite only in the powerhouse. Even the generating units of the two schemes are different in terms of head and discharge.
Tinokari scheme is located south, it generates 5.8 MW coming from approximately 2.5 m³/sec discharge and 275 meters of net head. Ranteangin scheme is located more on the north, it will generate 4 MW coming from 5 m³/sec flow of water and 95 meters of net head.
Yaentu MHPP is located not far from our Tomasa MHPP, it is also located in Central Sulawesi Province. In terms of average annual rainfall, Central Sulawesi has one of the highest numbers nation wide, which is a value for run-off river hydropower plants. From a 7.37 m³/sec of water discharge and 165 m of net head we obtain a 2 x 5 MW power output.
Weir elevation is 590 meters above sea level, it diverts water to the intake then the desedimentation basin. Waterway is composed of two different structure, open channel is 2536 meters and 250 meters of headrace culvert to the Forebay tank. From the Forebay tank water is conveyed to the turbine by means of a 475 meter long penstock.
The construction is planned to start at second half of 2015.
