The Indonesian government is working to increase the share of renewable energies in the electricity mix in order to cope with the rapidly growing electricity consumption. At present, the share of renewables in the electricity mix is 5-6%. An increase to 19% is planned by 2019 and 25% by 2025.
At the end of 2014, according to the Indonesian Ministry of Energy, renewable energies with a total capacity of almost 11,000 MW were installed. 70% accounted for hydropower, the remainder was divided into roughly equal parts of geothermal energy and biomass.

The customer
To achieve the ambitious objectives for 2019 and 2025, the government commissioned a local engineering company to build a generator for future public energy supply. That company gave Forbo Movement Systems the opportunity to collaborate in the development of a power transmission solution for a hydropower generator.
Application
Within the framework of the government funded microenergy program, large power stations are to be gradually replaced by smaller units. The energy source for hydropower plants is water power – whether in the form of a calmly flowing river or a waterfall. The transmission of the flow of energy from the propeller to the generator involves very heavy loads, which require an extremely robust belt as a transmission medium.
Our belting solution
These are exactly the conditions for which our Extremultus power transmission belts were created, and which they have no difficulty dealing with. The belts are long-lasting, extremely robust, elastic as well as vibration- and shock- absorbing. This means that they can be used in practice at belt speeds of up to 100 m/s.
In the course of the valuable collaboration for the pilot project, Movement Systems and the institute that builds hydropower plants were able to elaborate the optimum solution and implement it successfully in practice. Until now, Extremultus belt GT 80P has been operating successfully for two years..
Result
This is the first time in Indonesia that microenergy is being used for public power supply instead of conventional energy from a large power station. The pilot generator has found great resonance with the government.
On the one hand, the solution is technically convincing, and on the other, it is a way to generate energy more cost-efficiently than in large power stations. Recently, Movement Systems supplied another belt, because of different application parameters, we delivered an Extremultus GT 54P black belt.
