R$21 billion will be allocated to plans for transmission lines and energy substations.
The National Electric System Operator (ONS) released, this Thursday, data from the Executive Summary of the Plano of the Medium-Term Electrical Operation of the National Interconnected System – PAR/PEL 2023 for the period from 2024 to 2028. The objective of map is to evaluate the infrastructure necessary to guarantee security in meeting electricity demand in the country over the next five years, within the National Interconnected System (without).
For this cycle, the contributions foreseen by the ONS total R$49 billion, with R$4,9 billion destined for new works and another R$44,1 billion destined for projects from previous cycles that do not yet have a grant. These **investments** aim to guarantee the efficiency and reliability of the national electrical system, making it capable of responding to the growing demand for electricity in a safe and sustainable way.
Investments in Transmission Lines and Substations
In this second group, there are, for example, R$ 21,7 billion needed to transmission lines and new substations, auctioned on December 15, 2023
- Collapse? This country has so much solar energy that it puts the conventional power grid at RISK
- New revolutionary wind turbine promises to generate 400% more energy and displace solar panels by 2024!
- Brazil's largest rooftop solar plant is delivered! It has 6,4 MW of power and 11,3 modules, making the country a reference in renewable energy!

New Investment Plans in the States
In the analysis by state, Maranhão leads the destination of future investments, with R$ 9,9 billion, followed by Goiás (R$ 8,5 billion), Minas Gerais (R$ 7,3 billion), Piauí (R$ 4,7 .4,6 billion) and Bahia (R$XNUMX billion).
Growing Share of Renewable Energy
The document also analyzed the challenges faced with the growing participation of intermittent renewable sources in the national electricity matrix, which makes managing the balance between load supply and demand even more complex.
In 2023, centralized wind and photovoltaic plants reached 38 GW of capacity installed.
Renewable Energy Challenges
According to the ONS, this level will reach 54 GW by the end of 2027 – the data does not include the expansion of Micro and Mini Distributed Generation (MMGD), a modality that can reach around 40 GW of installed power by 2027.
‘An electrical sector with this design needs sufficient flexibility to allow the operation to maintain control of the balance of load versus generation and optimally utilize the capacity of the transmission system', says the document.
Dispatchable Generation and Transmission Systems
To compensate for the high variability caused by renewables, the ONS estimates dispatchable generation ramps of around 25 GW on working days in January 2024.
The perspective is that this ramp will reach 50 GW in 2028, representing an increase of 100%.
PAR/PEL 2023 also highlights that the investments planned in expanding the transmission system will allow the full flow of surplus generation from the North/Northeast to the South/Southeast/Central-West to meet the load, from 2029 and 2030.
Impact of Broadcast Auctions
According to the document, it is a direct result of the transmission auctions held in June and December 2023, in addition to the next auction to be held in 2024.
