Royal HaskoningDHV and Tirasa (pioneering energy investment company in Indonesia) signed an agreement with the intention to collaborate in developing of small scale hydropower plants along the Merawu river in Central Java, Indonesia, with a total capacity of 100 MW . The signing took place on 21 November 2013 during the Indonesia-Netherlands Business Diner on the occasion of a Dutch trade mission lead by Netherlands Prime Minister Mark Rutte. The five-year agreement commenced with feasibility studies and reviews within targeted areas. An estimated 400,000 people could benefit from connected to the grid because of these hydropower plants.
Having completed a hydrological study and reviewed the local feasibility study, Royal HaskoningDHV is now preparing detailed design and tender documents for four mini hydropower plants in Central Java that will provide a sustainable source of energy for around 55,000 people. The project also involves arranging permits and licenses with local government and energy company and power off-taker, PLN.
These four hydropower plants represent the first phase in the program to provide a total installed capacity of 100MW by 2018.
A report by Differ Group in 2012 stated that Indonesia's electricity generation capacities are outdated and insufficient, operating at an average capacity factor of 66%. It also stresses that the country experiences daily blackouts lasting on average 4 hours a day and claims that more than 86 million Indonesians still lack even the basic access to electricity. Similarly the World Bank identifies that the provision of reliable electricity in Indonesia as a pressing issue. In a 2011 report it ranked Indonesia as being 161st amongst 183 countries surveyed as to the ease of getting reliable electricity supply for business.
These hydropower plants provide a sustainable solution to the lack of supply experienced in Indonesia. The 30 million USD program for four hydropower plants expects a return on investment of less than seven years. The impact on the local environment will be small and manageable. Local communities have been involved in the process through events and campaigns arranged by Tirasa and the regional government.
The hydropower project has been discussed at local community meetings.

To provide a sustainable source of energy for around 55,000 people in the first phase of the program.
Four hydropower plants with a total capacity of 15,6 MW.
The impact of these plants will bring wider benefits to the local societies. The availability of power will support increased economic activity, and the plants themselves will provide employment locally.
The project consists of 4 cascaded run-of-river hydropower plants which will deliver energy to the grid. The construction consists of weirs, sediment traps, waterways, head pond and penstocks. The powerhouses will each contain several turbines to generate electricity. A transmission line will connect to the 20 kV grid, and access roads will also be constructed. Details of the facilities are: 6MW each at Karekan and Pandansari, 2.4MW in Watupayung and 1.2MW in Tempuran.
