1. Last Updated

The Last Updated section of the page tells you when Transelectrica has last updated the status of the grid.

2. Last Connected

The Last Connected section of the page tells you when our backend server has last pinged Transelectrica for any new updates.

3. Connection Status

The Connection Status section of the page tells you if our backend server has an active connection to Transelectrica.

This section can display either Active or Inactive depending on the current status.

The connection might be inactive for various reasons, but usually this is temporary and resolves automatically.

4. Consumption

The Consumption section of the page displays the total amount of power transmitted through the Transelectrica electrical grid, including energy imports and exports. To calculate total power consumption, we add cross-border electricity transfers to the internal production.

5. Production

The Production section of the page displays the total amount of power generated within the country. To determine electricity production, we subtract energy imports from the total power consumption.

The pie chart provides a visual representation of this data. The outer ring displays the percentage contribution of each production source—such as coal, gas, and hydro—to the total electricity generated. The inner ring categorizes these sources into three groups: fossil fuels, renewables, and other. At the center of the chart, you'll find the total electricity being generated along with a percentage indicating how much the generated power meets consumption demand. This percentage may exceed 100% if energy exports occur due to a surplus relative to national demand.

6. Transfers

The Transfers section of the page displays the total amount of cross-border electricity exchanges. This value is always positive, regardless of whether power is being imported or exported.

Additionally, you will find a detailed breakdown of energy imports and exports for each country directly interconnected with Romania, along with the total transferred amount.

7. Production Sources

A) Fossil Fuels   - This section displays the total percentage of electricity generated from fossil fuels (coal and gas), along with a breakdown of contributions from each source.

B) Renewables   - This section displays the total percentage of electricity generated from renewable sources (hydro, wind, solar, biomass), along with a breakdown of contributions from each source.

C) Other   - This section displays the total percentage of electricity generated from other sources (nuclear, battery storage), along with a breakdown of contributions from each source.

8. Estimated Emissions

The Estimated Emissions section provides an approximation of CO₂ emissions from each relevant electricity production source—coal, gas, and biomass—measured both per hour and per kWh.

To estimate emissions, the following average values have been assumed:

 • Coal: 1000 g/kWh
 • Gas: 600 g/kWh
 • Biomass: 50 g/kWh
 • Renewables & Nuclear: 0 g/kWh

Hourly emissions (in tons) are calculated by multiplying the power output in megawatts (MW) by the emission factor, then converting grams to tons.

Per kWh emissions are determined by dividing the total CO₂ emitted (in grams) by the total energy produced, resulting in a grid-wide CO₂ intensity in g/kWh.
