Red Flag in Energy: Understand Why the Electricity Bill Gets More Expensive
Have you noticed that suddenly your electricity bill increased and heard about the red flag in energy? It’s not magic or a prank: we will explain simply what this means and how it affects your wallet!
We are going through one of the most critical drought moments Brazil has ever faced. The lack of rain not only influences the humidity in the air but also affects the value of your electricity bill. This happens because, during dry periods, the reservoirs of hydroelectric plants are low, and the country needs to resort to more expensive energy sources, like thermoelectric plants.
But What Is the Red Flag in Energy?
The red flag in energy is an alert system created by the National Electric Energy Agency (ANEEL) to inform consumers that the cost of electricity production has increased. It works like a traffic light:
-
The Brazilian state accelerates industrial competitiveness with a focus on the extraction of strategic minerals to boost the energy transition in Goiás.
-
A Canadian retiree creates a hydroelectric system on a real river, generating energy continuously throughout the day and demonstrating how the power of water can supply a house with stability even in a simple structure.
-
Petrobras reaffirms its commitment to the market and ensures that it will carry out the energy transition safely to maintain national sovereignty.
-
Researchers discover a possible hydrogen deposit of up to 46 million tons beneath an ancient coal basin, and the volume could exceed half of the entire global production.
- Green Flag: favorable conditions for energy generation, with no extra cost on the bill.
- Yellow Flag: less favorable conditions, with a small increase in the bill.
- Red Flag: unfavorable conditions, with higher additional costs.
The red flag is divided into two levels:
- Level 1: the situation is complicated but under control. There’s an increase of R$ 4.463 for every 100 kWh consumed.
- Level 2: the maximum alert! The additional cost rises to R$ 6.498 for every 100 kWh consumed.
Why Does the Electricity Bill Get More Expensive Under the Red Flag?
When the red flag in energy is activated, it means that hydroelectric plants are unable to meet demand due to water scarcity. To avoid blackouts, the National Electric System Operator (ONS) needs to activate thermoelectric plants, which generate energy from burning fossil fuels like diesel and natural gas.
These energy sources are more expensive and less efficient, which increases production costs and, consequently, is passed on to consumers through the extra charge on the electricity bill.
How Do Tariff Flags Impact Your Day-to-Day?
Besides affecting your wallet, the red flag in energy is a signal for all of us to adopt conscious consumption practices. Saving energy during this period is not just a financial matter, but also a sustainability issue.
Tips to save:
- Turn off appliances that are not in use.
- Make the most of natural light.
- Use LED bulbs, which are more energy-efficient.
- Avoid very long showers and very hot water.
