Brazil power regulator calls for more hydropower reservoirs

Large water reservoirs act as potential energy storage, but the country has not built any new storage reservoirs since the 1980s

Sao Paulo, May 9, 2012 — Brazilian power regulator Aneel says environmental restrictions on hydroelectric dams are limiting the nation's potential to expand its renewable energy sector.

Large water reservoirs act as potential energy storage, but the country has not built any new storage reservoirs since the 1980s, according to Aneel, and the government has no clear plans to construct new ones.

Run-of-the river dams require little or no water storage meaning fewer environmental impacts on natural ecosystems.

Major hydroelectric projects Belo Monte (11.2 GW), Santo Antonio (3.15 GW), Jirau, (3.75 GW) and Tapajos (6.1 GW) will all use run-of-the-river generation.
