T/G supplier: ASEA, Kvaerner
EPC: SABCON
Quick facts: 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. The first
study for Mrica was commissioned in 1970, but work did not get
underway until Dec 1982. After 6mos, construction had to be halted
until Mar 1984 for financial reasons. The main project dates were
originally set back two years, but it took less time than expected to
restart; at the end of the contract, only about a year was lost and the final
turbine was commissioned 2mos ahead of schedule.
