Peak hours, seasonal hours – also known as peak time – are expressions related to electricity consumption. They are generally used by large consumers who require higher voltage and deal with high energy consumption.
What is Peak Time or Seasonal Hours?
The consumption mode known as peak hours corresponds to a pricing format that relates electricity consumption to the time of day when this consumption occurred. Also known as Seasonal Hourly Rate (SHR), it is directed to a specific group of customers with special energy demands.
Characteristics of Group A Customers
- Supply provided through a dedicated substation
- Supply voltage higher than common consumers
- High electricity consumption
- Typical profile: industries, large businesses, and large condominiums
How Peak Time Pricing Works
Rates vary according to:
- Time of day: Periods of higher demand have differentiated pricing
- Seasonality: Annual variation based on rainy and dry periods
Peak Hours
Usually understood between 5 PM and 8 PM, a period when energy demand reaches its peaks. During this period, the rate can be significantly higher.
Impact of Energy Generation
The Brazilian system has unique characteristics:
- Large participation of hydroelectric plants
- Variation in generation capacity according to reservoir levels
- Activation of thermoelectric plants during dry periods, with higher operational costs
Seasonal Hourly Rate Modalities
1. SHR-Blue
Main characteristics:
- Specific demand for peak hours
- Differentiated rate for off-peak consumption
- Recommended for companies with stable consumption throughout the day
2. SHR-Green
Main characteristics:
- Single demand for the entire period
- Ideal for those with distributed generation
- Allows integration with own generators
Advantages of Using Generators During Peak Hours
Cost Reduction
- Own generation can be more economical than peak rates
- Possibility of operation at strategic times
Energy Efficiency
- Better use of energy resources
- Reduction of losses in the distribution system
Sustainability
- Lower environmental impact by reducing the need to activate thermoelectric plants
- Optimization of energy resource use
