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. INDONESIA POWER GENERATION http://repit.wordpress.com/ [email protected] 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. Type Hydro Power Plant Area Central Java Kind of Fuel Hydro 1 PB.

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. INDONESIA POWER GENERATION http://repit.wordpress.com/ [email protected] 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%.
