May 4 -- Ministry of Mines and Energy, Government of Brazil issued the following news release:
- Wet period ends in significantly better conditions than those seen in recent years.
The Electricity Sector Monitoring Committee (CMSE) met this Wednesday (05/04), on an ordinary basis, and evaluated, among other matters, the conditions of electricity supply to the National Interconnected System (SIN).
As highlighted by the National Electric System Operator (ONS), in April 2022, there was continuity of rainfall in the South region, resulting in greater inflows to hydroelectric plants and the respective recovery of storage conditions. In the other regions, rainfall was predominantly below the historical average, with little rainfall in the Southeast/Center-West basins, a behavior compatible with the beginning of the dry season.
Even so, the improvement in service conditions in the South region also had a positive impact from the systemic point of view of the SIN, contributing, together with the success of the strategies adopted in the recent past, so that the typically wet period ended with the largest equivalent storage of the subsystems. Southeast/Midwest, Northeast and North verified in recent years. At the end of April, equivalent storage of 66.5%, 67.1%, 96.1% and 99.0% were achieved in the Southeast/Midwest, South, Northeast and North subsystems, respectively, and the forecast for the end of May in these subsystems is 69.0%, 84.6%, 94.0% and 99.6%.
In addition, the prospective studies, which included evaluations extended until the end of November 2022, indicated full compliance in terms of both energy and power throughout the period, without the need to use the operating reserve.
In view of the scenario presented, the conclusion of the CMSE Working Group, established at the 247th meeting of the Committee, held on May 5, 2021, was reported to periodically monitor the conditions of service to the SIN and sectoral articulation with a view to guaranteeing service. As highlighted, in this forum, important discussions were held that resulted in the construction of strategies that guided the sector's action in facing the water scarcity experienced.
Since May 2021, more than 30 meetings of the Group have been held, which also included the participation of invited institutions, namely the National Agency for Water and Basic Sanitation (ANA) and the National Center for Monitoring and Alerts for Natural Disasters (Cemaden ). From now on, the CMSE technical meetings will be held again as needed and for debates on specific topics, in support of the evaluations conducted by the Collegiate.
Finally, among other matters, the Energy Research Company (EPE) presented the 1st First Quarterly Review of Load Forecasts for the Annual Planning of the Energy Operation 2022-2026. As mentioned, the projection for 2022 is for growth of 1.7%, representing a decrease in relation to the previous expectation of 2.7%. For the period 2022-2026, the projected average growth is 3.4% per year. The documentation associated with the study can be consulted on the websites of the ONS, the EPE and the Electric Energy Commercialization Chamber (CCEE), institutions that jointly carried out the work.
The CMSE reaffirmed its commitment to guaranteeing safety and reliability in the supply of electricity in the country in the current and future scenario, through the continuity of the permanent monitoring carried out, supported by studies carried out from the different perspectives of the Brazilian electricity sector, and with the synergistic and robust action of the institutions that make up the Committee.
Technical Information :
Hydrometeorological Conditions: the month of April was marked by a long period of absence of precipitation in the Southeast, Midwest and Northeast regions, resulting in a negative index in the hydrographic basins located in these regions. In basins located in the South, the frequent passage of cold fronts favored the occurrence of precipitation and had a positive impact. In relation to Affluent Natural Energy (ENA), values ??below the historical average were verified for the month of April in the Southeast and Northeast subsystems, while for the North and South regions a more favorable condition of inflows was observed. Considering the aggregate ENA of the National Interconnected System (SIN), in April a value close to 87% of the Long Term Average (MLT) was verified. For the month of May, the closing forecast indicates an ENA below the historical average for the Southeast and Northeast subsystems, close to the MLT in the North subsystem and a more favorable condition is foreseen for the South subsystem. Regarding the system as a whole, the monthly forecast for May is 84% ??of the MLT.
Stored Energy : at the end of April, storage equivalents of 66.5%, 67.1%, 96.1% and 99.0% were verified in the Southeast/Midwest, South, Northeast and North subsystems, respectively, and forecast for the end of May in these subsystems is 69.0%, 84.6%, 94.0% and 99.6% of the EARmax. For the SIN, the forecast for the end of May is 76.1% of the EARmax.
Expansion of Generation and Transmission : the expansion verified, in April 2022, was approximately 223 MW of installed capacity for centralized electricity generation, 645 km of transmission lines and 400 MVA of transformation capacity. Thus, in 2022, the expansion totaled 1,568 MW of installed centralized generation capacity, 3,595 km of transmission lines and 9,286 MVA [1] of transformation capacity. Regarding distributed generation, the expansion verified in 2022 was 1,997 MW, reaching a total of approximately 10.5 GW installed in the country.
The CMSE, within its legal competence, will continue to monitor, on a permanent basis, the supply conditions and service to the country's electric energy market, adopting measures to guarantee the supply of electric energy. The final definitions of today's CMSE meeting, as well as the other deliberations of the Board, will be consolidated in minutes duly approved by all the members of the board and published in accordance with the bylaws.
