Power generation

18 generating units were installedusing slip form technique.

Francis turbine measuring 16m and

weighing 800tons capacity ofgenerating 715mw of power.

2 more were installed in 2006-07 for

generating larger power.It was able to serve 75% of total

power consumed by Paraguay and25% of brazil.
