    Brazil: CMSE evaluates service conditions and perspectives for 2023

    December 8, 2022 - Brazil Business News


      The Electrical Sector Monitoring Committee (CMSE) met this Wednesday (12/07), on an ordinary basis, and evaluated, among other matters, the conditions of electricity supply to the Brazilian Electric System.

      Original Press Release:

      Dec. 7 -- Ministry of Mines and Energy of Brazil issued the following news release:

      - In the last ordinary meeting of the year, the Collegiate highlights institutional commitment to face the challenges experienced in recent years and points to good perspectives for the next year.

      The Electrical Sector Monitoring Committee (CMSE) met this Wednesday (12/07), on an ordinary basis, and evaluated, among other matters, the conditions of electricity supply to the Brazilian Electric System.

      As highlighted by the National Electric System Operator (ONS), in November 2022, the rains observed in the country continued, expected behavior for the typically wet period, with the verification of inflow values to hydroelectric plants lower than the historical average in all the subsystems of the National Interconnected System (SIN). In terms of equivalent storage, the values remained well above those of 2021, with emphasis on the Southeast/Center-West, which ended the month with 46.5%, which will contribute to the guarantee and security of service in the coming months.

      Regarding the prospective studies, which included evaluations extended until the end of May, the ONS registered the indication of full compliance both in terms of energy and power throughout the period, with perspectives of storage levels higher than those verified in the last year.

      Among the highlights of the operation, the successful adoption of special measures during Brazil's games in the 2022 World Cup was also mentioned, guaranteeing the supply of electricity to Brazilian consumers, which will continue to be carried out until the end of the competition. In addition, the continuity of thermoelectric energy exports to Argentina on a commercial basis was registered, as well as the unnecessary, given the verified scenario, of the approval of offers of additional resources received in the scope of the Demand Response program.

      Additionally, the ONS made a presentation on the preparation of reference storage curves (CREF) for 2023, which represent an important tool to aid the Committee's decision-making regarding the need to adopt or maintain additional measures with a view to guaranteeing energy supply in the Country. The theme will be studied in depth, including aspects of methodology and the use of curves, and should be presented in due course to the CMSE for deliberation, maintaining the commitment to the transparency and robustness of the assessments conducted by the Collegiate.

      Finally, among other topics, there were presentations by the National Electric Energy Agency (ANEEL) and the Electric Energy Trading Chamber (CCEE), which included a retrospective overview of the topics addressed by the institutions throughout 2022. Thus, the synergistic action between the institutions of the Brazilian electricity sector was evidenced, enabling the successful confrontation of different challenges and guaranteeing the supply of electricity in Brazil.

      With regard to ANEEL issues, it is also worth mentioning the proposed methodology for assimilating plants that did not sell energy at auction, that is, plants in the Free Contracting Environment (ACL), in the block of offers considered in the Monthly Operation Program (PMO /ONS), as assessed in Subsidy Intake No. 9/2021 carried out by the Agency. After evaluation, the CMSE decided to initially consider the new methodology in a shadow process, to be carried out throughout 2023, without affecting price formation and electroenergetic optimization, to assess the impacts of the proposal, in order to support a new appreciation of the subject by the Collegiate, which should occur by July 2023, as well as the rebates by the Permanent Commission for the Analysis of Methodologies and Computational Programs of the Electricity Sector (CPAMP).

      Technical Information :

      Hydrometeorological Conditions : in November, the highest precipitation totals occurred in the basins of the Tocantins and São Francisco rivers, in the section between the Três Marias and Sobradinho hydroelectric plants, which presented values above the historical average. Regarding Affluent Natural Energy (ENA), values below the historical average were verified in all subsystems. Considering the aggregated ENA of the National Interconnected System (SIN), a value of 80% of the Long Term Average (MLT) was verified. For December, and according to prospective studies presented at the meeting, ENA values for the SIN are expected to be between 63% and 84% of the MLT, depending on the scenario considered.

      Stored Energy : at the end of November, equivalent storage of 46.5%, 78.3%, 58.5% and 51.7% were verified in the Southeast/Midwest, South, Northeast and North subsystems, respectively. For the SIN, storage at the end of November was 51.1%. The forecast for the end of December 2022 in the SE/CO subsystem, according to the prospective studies presented, varies between 46.3% and 48.6% of the EARmax. For the SIN, the forecast varies between 46.8% and 51.4% of the EARmax.

      Expansion of Generation and Transmission : the expansion verified in November 2022 was of approximately 1,030 MW of installed capacity of centralized generation of electric energy, 1,223 km of transmission lines and 750 MVA of transformation capacity. Thus, in 2022, the expansion totaled [1] 7,107 MW of installed centralized generation capacity, 7,929 km of transmission lines and 20,071 MVA of transformation capacity. Regarding distributed generation, the expansion verified in 2022 was 7,026 MW, reaching a total of approximately 15.6 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 on today's CMSE meeting will be consolidated in minutes duly approved by all collegiate participants and disclosed in accordance with the bylaws.
