The Electricity Sector Monitoring Committee (CMSE) decided on Friday (8) to increase the number of thermoelectric power plants operating in the country in order to preserve the reservoirs of low-storage hydroelectric power plants due to the lack of rain.
In a note, the committee announced that as of this Saturday (9), the production costs of the thermoelectric power plants of the subsystems of the South-East, Central-West and South are the same. would rise to R $ 588.75 per MWh. ).
The document also states that the measure is intended to preserve the reservoirs of hydroelectric plants, taking into account the "weather forecast for the coming days". In recent days, precipitation has been below the historical average.
Also according to the note, the operator of the National Electrical System (ONS) "must consider the power supply of Uruguay and Argentina as an additional resource" to preserve Brazilian reservoirs.
Despite the measures, the committee reported that the supply of energy for 2019 is guaranteed and that "there are available energy resources, including in addition to the quantities already shipped by thermoelectric power plants".
Thermoelectric plants use fuel, such as oil and gas, to produce energy. This is why the government can activate them to replace some of the hydroelectric production and, thus, save water from the reservoirs.
The problem is that, because of the use of fuel, the energy generated by thermoelectric power plants is more expensive and that their activation has a direct impact on the electricity bill.
The increase of this type of production may trigger the tariff signaling system. In February, the green fee is in effect, which does not entail any additional cost on the electricity bill. However, with the increased use of heat, the flag may turn yellow or red, resulting in additional charges on the light indicator.
