Resumo:
After publishing the law 9.433/97 which establishes the national politic for hydraulic
resources, the electric sector has lost the full control in operating its reservoirs, being now
responsibility of Water National Agency together with National System Operator regarding
operating directions.
This Agency’s main attribution is to guarantee water multiple use and therefore must
be the moderating agent for eventual conflictive interests involving the water of hydraulic
power reservoirs.
With the purpose of clarifying this point, this study intends to show a calculation
method in order to calculate the relevant impacts that emptying of a reservoir may cause to
several users.
This method elaborates equations that relates emptying of a regulatory reservoir with
benefit or incremental economic loss that any specific activity using directly water may
suffer.
This study allows bordering districts to reinforce future damage complains due to
losses caused by reservoir emptying. In other hand, energy generation companies may also
use this study as an instrument able to define limits of a regulatory reservoir emptying without
losses for both parties.
