2.7 SIN transmission lines extension (km)

The transmission lines accounted for are those belonging to the ONS basic network.

2.8 Peak Demands (MW)

The data comes from the ONS Technical Database and reflects the load served by plants supervised and scheduled by ONS, including the estimated value of Micro and Mini Distributed Generation (MMDG) based on forecast meteorological data.

2.9 Energy Load by Subsystem (MW average)

Until December/2014, the data represent the load served by plants dispatched and/or scheduled by ONS, based on data received by the ONS Supervision and Control System.

Between January/2015 and February/2021, the data represent the load served by plants dispatched and/or scheduled by ONS, as well as plants not dispatched by ONS. All data are verified and come from the Measurement System for Billing, which are sent by CCEE to ONS.

From 04/29/2023: in addition to the previously considered data, the estimated value of micro and mini distributed generation (MMDG) based on verified meteorological data was incorporated.

2.10 Hourly Load (MW average) and Dispatchable Generation (MW average) for the Peak Load Day

Initially, the day of highest load for each subsystem and for the SIN as a whole for a given year was determined, based on the sum of the hourly load throughout the day. This procedure resulted in five days of highest load, one for each of the four subsystems and one for the SIN. After that, the hourly load and dispatchable generation data were obtained for these days.

The dispatchable generation data considered hydraulic and thermal generation.

2.12 Average Tariffs by Region and End-Use Sector (R$/MWh)

Without taxes.

2.13 Average Tariffs by Supply Voltage (R$/MWh)

Without taxes.

The average tariff value by supply voltage is calculated by dividing the total supply revenue by the total electricity consumption in a given year.

2.14 Electricity Supply Quality Indicators by Region and by Type of Authorization - DEC (average number of hours) and FEC (average number of interruptions) and 2.15 Electricity Supply Quality Indicators by State and by Type of Authorization - DEC (average number of hours) and FEC (average number of interruptions)

The DEC indicator corresponds to the “Equivalent Duration of Interruption per Consumer Unit”, measuring the average time a consumer is without electricity during a given year.

The FEC indicator corresponds to the “Equivalent Frequency of Interruption per Consumer Unit”, measuring the average number of times the electricity supply is interrupted for a consumer.

2.17 Consumption (GWh) - Top Ten Distribution Agents 2025

Consumption only considers energy consumed from the grid, i.e., it does not include the portion of self-consumption from MMDG (Micro and Mini Distributed Generation) or self-production consumed and not transported.

2.20 LpT Program (“Rural”) - households attended by region and Brazil

Households served with Distributor Resources are also counted here.

The accumulated data correspond to households served since 2004.

2.22 Sales of light electrified vehicles in Brazil by technology (units)

Does not consider hybrid vehicles (HEV), hybrid flex (HEV Flex), or micro-hybrids (MHEV), as these do not consume electricity from the grid.

Chapter 3

3.1 Consumption by region (GWh) until 3.8 Consumption by end-use sector and region (GWh)

Consumption only considers energy consumed from the grid, i.e., it does not include the portion of self-consumption from MMDG (Micro and Mini Distributed Generation) or self-production consumed and not transported.

3.9 Average consumption per consumer by subsystem (kWh/month), 3.10 Average consumption per consumer by region (kWh/month) and 3.11 Average consumption per consumer by state (kWh/month)

The average consumption per consumer is obtained by dividing the average monthly consumption value for a given year by the average monthly number of consumers for the same year

The consumption used for calculating the average consumption per consumer only considers the energy drawn from the grid; that is, it does not include the portion of self-consumption from Micro and Mini Distributed Generation (MMDG) sources or self-production consumed and not transported.

3.12 Average annual per capita consumption by region (kWh/person) and 3.13 Average annual per capita consumption by state (kWh/person)

The average annual per capita consumption is obtained by dividing the total consumption value over the year by the total number of inhabitants for that same year.

The consumption used for calculating the average annual per capita consumption only considers the energy drawn from the grid; that is, it does not include the portion of self-consumption from Micro and Mini Distributed Generation (MMDG) sources or self-production consumed and not transported.

Chapter 4

4.1 Consumption by end-use sector, region and state (GWh) and 4.3 Consumption by Segment - top ten (GWh)
