Dam Safety
GRI EU21
< 48 >
In 2022, the safety of our dams underwent an
Integrated Management System (SGI) external audit,
covering ISO 14001 and ISO 45001 as well as the
Asset Management System (ISO 55001).
The dams in the hydropower plants under our
concession are structures consolidated, designed, built
and maintained according to the strictest Engineering
technical standards. Additionally, every year, we update
and send to civil defense bodies our Emergency
Action Plan (PAE), a technical and administrative
proceeding to help them prepare local contingency
plans, in order to address emergencies involving the
dams. In line with the provisions of Law 12,334/2010
and Aneel Resolution 696/2015, we send Aneel's Dam
Safety Form (FSB) to the inspecting agent every year.
Our management activities include controlling full
reservoir levels and adjusting the flow rate, using the
Emergency Situation Operation System (SOSEM).
We provide internal trainings on SOSEm, which
establishes the proceedings for opening the weirs at
full reservoir level, as well as communication actions
with society, with the aim to mitigate hydrological risks
and restore normal operation conditions. We educate
the communities neighboring our plants on the safe
use of the reservoir and its surroundings for leisure and
entertainment activities.
By periodically monitoring reservoirs, not only do
we control environmental conditions in these places
but also report any irregular occupations in our
4,800-kilometer borders. Every case of irregular
occupation identified generates a Property and
Environmental Inspection Report (Ripa), which is
made available through the Geographic Information
System (GIS or Sistema Geo Catálogo in Portuguese),
the Ministry of Environment's satellite image catalog.
Since dams are a set of extremely important assets, their management is governed by the Dam Safety Plan,
which comprises the following actions:
Monitoring through the reading
of civil instruments every two
weeks and issuing a bimonthly
consolidated report;
Inspecting civil structures by using
drones, mini-submarines and
remote-controlled boats;
Preparing a Visual Inspection
Report and completing the
Dam Safety Form, both with
a yearly periodicity;
Inspecting outlet structures on a
yearly basis, and issuing a report
and an action plan for the non-
compliance items identified;
Real-time monitoring of tributaries
and reservoirs through
telemetry stations;
Having a preventive
maintenance plan.
