The power sector in Brazil was essentially in government's hands until the early 1990s. The sector had seen remarkable development in the 1970s. However, by the late 1980s, the state-ownership model was on the verge of collapse. This delicate situation was the result of heavily subsidized tariffs and a revenue shortfall in the sector of about US$35 billion, which led to the delay in the construction of about 15 large hydro plants due to lack of funds for investment. Efforts to addres. [pdf]
