    MRICA HEPP (Indonesia Power Generation Business Unit)

    Mrica Generation Business Unit is one of eight GBU in Central Java that are owned and operated by PT

    Indonesia Power in Central Java. Mrica GBU is a hydro power plant utilizing a Dam, Reservoir or Run of

    River system.


    Mrica Generation Business Unit has 25 power generators within 14 locations and has 318.84 MW

    installed capacities.

    In 1971, Indonesia received aid from the Australian government to develop water resources for power

    generation. From the results of the study by Snowi Mountains Engineering Corporation (SMEC) in 1972

    proposed Maung and Mrica in watersheds Serayu for hydropower.

    As it goes in 1974 conducted a feasibility study on watershed Serayu. In 1978-1980 compiled detailed

    planning design by Teknopromn Export from the USSR. On May 15, 1982 conducted the working

    contract between PLN and Sabcon (Scansa Comentgjuteriet, Asea AB and Sweedee Balfour Beaty

    Construction LTd), and United Kingdom. As a consultant planner was SWECO AB of Sweden and

    engineering and power teknopom export from the UK, while Wiratman and Ass redesign planning

    results made by Teknopromexport (TPE). As the Supervisor Consultant was Sir William Halcrow and

    Parners of England.

    1. PB. Sudirman

    Sudirman (Mrica) Hydroelectric Power Plant Indonesia is located at Bawang, Central Java, Indonesia.

    Location coordinates are: Latitude= -7.3927, Longitude= 109.6054. This infrastructure is of Type Hydro

    Power Plant with a design capacity of 181 MWe. It has 3 unit(s). The first unit was commissioned in 1988

    and the last in 1989.

    This multipurpose scheme has a 800m long, 110m tall earth-filled and rock main dam across the Serayu

    River. Other high-level dams stretch out on either side of the main dam to give a total crest length of

    more than 5km. The open-air power house is connected to the reservoir by a 570m pressure tunnel.

    2. Jelok

    Jelok Hydropower Plant in Tuntang District, Semarang regency, has been in operation since 1937.

    Electricity from the plant was once a major supplier of electricity demand in gemeente or municipal

    Salatiga formerly inhabited by the Dutch. Jelok is the oldest hydroelectric power plant in Indonesia

    because it operated in 1937 and managed at the time by the Dutch Government ANIEM. However, in

    1955 Hydropower Jelok successfully taken over by Indonesian.

    Jelok Hydroelectric power plant utilizing a stream of water from natural reservoirs Rawa Pening with its

    capacity of 20.48 megawatts.

    In the history manuscript of the national electricity which is always read every ceremony on October 27

    and in the text of a short handover PT Indonesia Power, which is recited on every Oct. 3, the name of

    Jelok hydropower plant unlikely called as the Central of hydropower Plant (HEPP) which was built by the

    Dutch whereas it was built in 1937.

    The second paragraph of the history of electricity just to mention: In 1927, the Dutch government

    established S'Lands Waterkracht Bedrijven (LB), a company that manages the Plengan hydropower,

    Lamajan hydropower, Tonsea Lama hydropower Plant in North Sulawesi and Steam Power Plant Jakarta.

    Jelok Hydroelectric is located in Semarang district about 45 km from the city of Semarang, or 15 miles to

    the northeast Salatiga. Jelok Hydroelectric currently managed by PT Indonesia Power, a PLN subsidiary

    engaged in power generation, among the 14 hydropower in Central Java under the responsibility Mrica

    Generation Business Unit.

    Three engine Unit were built in 1937 and 1962, plus 1 unit more. With the water falls a height of 144

    meters and installed power 4 capacity of 4 x 5.12 MW Jelok Hydroelectric can generate electricity by 93

    GWh / year. Turbine made by Werk Escher Wyss Holland Spoor with horizontal Francis rotating shaft

    type made by Oerlikon AG Brown Hemaf Generators in rotation of 600 rpm.

    Water that moved the turbines were taken from Rawapening lake intercepted by the Tuntang river

    which was then dammed by a dam that is equipped with 6 water gates.


    Although it was already more than 70 years, the Jelok hydropower plant engine still operated as in good

    condition with relatively low operating costs. Meanwhile, to keep and maintain the reliability, in 1994

    generating engine was renovated by replacing the governor and the main inlet valve, retrofit 9 control

    system and rewinding the generator stator.

    Once before the interlinked of electrical interconnection system in Java, Jelok hydropower is one of the

    power plants that are vital to meet the electricity needs in Central Java. Based on installed capacity,

    Jelok Hydroelectric current contribution to the production of UBP Mrica range of 6.37%.
