Energy Central-News Article

The monthly meeting of the Electrical Sector Monitoring Committee (CMSE) held this Monday (18/09), at the headquarters of the Ministry of Mines and Energy (MME) CMSE evaluates ensuring the supply of electrical energy in the country. Since August, the heat wave has persisted and the consequent rise in temperatures in all capitals.

Key Highlights:

* In the South Region, there was a low pressure system and two cold fronts, resulting in high precipitation totals in Rio Grande do Sul.

* The National Interconnected System (SIN) recorded the best storage for the month of August, with 78% equivalent storage.

* The Electric Energy Trading Chamber (CCEE) reported that the process of exporting energy from thermal plants, from January to August 2023, totaled 511 average Megawatts (MWmed), with a compensation of R$103 million to the Bandeiras Account .

- Permanent monitoring carried out by the Committee strengthens sectoral action in favor of Brazilian consumers

The monthly meeting of the Electric Sector Monitoring Committee (CMSE) was held, this Monday (18/09), at the headquarters of the Ministry of Mines and Energy (MME), in Brasília, with important debates related to ensuring service and future perspectives. According to the National Electric System Operator (ONS), since August, the scenario has been one of continuation of the typically dry period in the country, with the persistence of a heat wave and a consequent increase in temperatures in all capitals. In the South Region, the action of a low pressure system and two cold fronts at the beginning of September resulted in high precipitation totals in Rio Grande do Sul, with volumes higher than the historical average expected for the entire month in the river basins. Jacuí, Uruguay and Taquari-Antas.

Also highlighted was the end of the month of August with the best storage in the National Interconnected System (SIN) in history (78%), reflecting the equivalent storages of the subsystems: Southeast/Central-West with 79%; South with 84%; Northeast with 73%; and North with 81%.

Regarding international exchanges, the Electric Energy Trading Chamber (CCEE) reported that, according to preliminary data, the process of exporting energy from thermal plants, from January to August 2023, totaled 511 average Megawatts (MWmed), with a compensation of R$ 103 million to Conta Bandeiras, in benefits for Brazilian electricity consumers in the Regulated Contracting Environment. The export of turbineable discharge totaled 847 average MW exported, from January to August 2023, with a financial result of approximately R$781 million for hydraulic generators.

Finally, among other matters, Aneel highlighted the publication of Normative Resolution No. 1,072/2023, the result of work carried out in recent years with CCEE, which had broad social participation. The initiative, related to the prudential monitoring of agents within the scope of the CCEE, will take place in 2023, through a shadow process, contributing to the activities that precede the opening of the Brazilian electricity market for high voltage consumers (group A), from January 2024, in accordance with MME Normative Ordinance No. 50/2022.

In addition to MME, nos and CCEE, representatives from the Energy Research Company (EPE), the National Electric Energy Agency (ANEEL), the National Petroleum, Natural Gas and Biofuels Agency (ANP) and the National Energy Agency were present. Water and Basic Sanitation (ANA).

Technical information:

Hydrometeorological Conditions:In August, the precipitation recorded was above the historical average in the Iguaçu River basin and in the incremental section to HPP Itaipu. In the other river basins of interest to the SIN, below-average rainfall predominated, except in the Paranaíba, São Francisco and Tocantins river basins, which had slightly higher rainfall. In relation to Affluent Natural Energy – ENA, values below the historical average were verified in all subsystems; the Southeast/Central-West subsystem presented conditions of 90% of the Long Term Average – MLT, while the South presented conditions of around 81%, the Northeast around 66% and the North approximately 68% of the MLT. The aggregated ENA of the SIN registered an index of 84% of the MLT. In September, according to the lower scenario, the indication is for an ENA below the historical average for the whole of Brazil, around 82%, 61%, 69% and 60% of the MLT, for the Southeast/Central-West, South, Northeast and North, respectively. With regard to the SIN, the study points to 73% MLT inflow conditions, being the 17th lowest value for a month of September, in a history of 93 years.

Stored Energy: in August, equivalent storages of around 79%, 84%, 73% and 81% were verified, in the Southeast/Central-West, South, Northeast and North, respectively. For SIN, storage was approximately 78%, the best condition seen in history. For the last day of September, the expectation is 70.7%, 83.1%, 67.3% and 73.4% of the EARmáx, considering the lower scenario, while for the upper scenario there is a forecast of 74.0% , 90.2%, 67.4% and 73.3% of EARmax. As for the SIN, the results for the end of the month should be 71.1% of the EARmax, for the lower scenario, and 73.9% for the upper scenario.

Expansion of Generation and Transmission: the expansion seen in August 2023 was approximately 1,357 MW of installed capacity for centralized electricity generation, 263 km of transmission lines and 675 MVA of transformation capacity. Thus, in 2023, the expansion totaled 7,064 MW of installed centralized generation capacity, 5,086 km of transmission lines and 14,336 MVA of transformation capacity. Regarding distributed generation, the expansion seen in 2023 was 7,042 MW, reaching a total of approximately 23.4 GW installed in the country.

The CMSE, within its legal competence, will continue to monitor, on a permanent basis, supply conditions and service to the country's electricity market, adopting measures to guarantee the supply of electricity. The final definitions of today's CMSE meeting will be consolidated in minutes duly approved by all participants of the collegiate and published in accordance with the regulations.
