Coal generating assets
According to the EPE's Ten-Year Expansion
Plan, coal-based plants will continue to play
an important role in the safety of the national
energy matrix, with dispatchable power to
support the expansion of renewable sources,
although they have a higher level of emissions
and consequent environmental impact. In this
context, we act to ensure national energy security
with the continuity of the operations of two
coal plants, Itaqui (360 MW) and Pecém II (365
MW), in order to achieve maximum efficiency
with the lowest possible environmental impact,
fully meeting the contracts in force in the ACR
(Itaqui until 2026 and Pecém II until 2027) and
playing a fundamental role for the energy supply
of the North and Northeast. Although we have
committed ourselves to no longer invest in new
coal-generating assets, we will continue to carry
out operations on these assets with a focus on
operational and environmental excellence during
the term of the ACR contracts.
The Itaqui TPP, which is our first venture in the
State of Maranhão, is strategically located, just
5 kilometers from the Itaqui port, facilitating the
receipt of imported coal for power generation.
The Pecém II TPP is located at São Gonçalo do
Amarante, in the Pecém Thermoelectric Complex,
in the State of Ceará. The asset uses the Port of
Pecém to receive the coal used in the generation
of electricity.
As differentials, the two plants have subcritical
boilers and use clean coal burning technology
(Clean Coal Technology), in addition to having
an automatic fault detection system in coal
conveyor belts (inspection of 3 to 4 meters per
second) through the use of drones, which brings
operational efficiency gain and mitigation of
the risk of coal conveyor stop. The track system
also forms a tunnel, preventing the dispersion
of particulates due to wind, or by the movement
itself, throughout the entire route. In Itaqui, we
also adopted control to minimize particulate
emissions in coal piles, through the application
of a polymeric material that creates a kind of film
and reduces the risk of coal retaining moisture
and thus losing efficiency. With this highlight,
itaqui's coal unloading system has been certified
since 2020 at ISO 14001, which attests to the
minimization of the environmental impact of the
process.
In 2021, the two assets recorded consolidated
operating results, with better availability,
efficiency and CO2 emissions than world
benchmarks, especially in the best quartile among
other global coal plants.
