Turbine rated power in megawatts
Tooltip The rated power of a gas turbine is its maximum continuous output in standard conditions*,​ measured in MW.
At temperatures above 15 °C, power output may drop by 15 – 30%.
For example: Turbine rated power = 23 MW
Adjusted power = 23MW x 0.7 = 16 MV​
*Standard conditions per ISO 2314:2009: 15 °C (59° F), 101.3 kPa (14.7 psi), and 60% relative humidity at sea level.

Turbine rated power should be in the range of 0-100 and equal or greater than the value of Compressor/Pump max shaft power

23 MW
Compressor/Pump max shaft power in megawatts
Tooltip The maximum shaft power of a compressor or pump is the highest mechanical power delivered to the shaft, defining its capacity to compress gases or pump fluids, measured in MW.

Electricity CO2 emission rate in gCO2eq/kWh
Tooltip Typical combined cycle gas power plant: Uses gas and steam turbines, utilizing waste heat for improved efficiency, with a default value of 350 gCO2eq/kWh.
Combined cycle gas power plant with carbon capture: Uses gas and steam turbines while capturing CO2 emissions to reduce environmental impact, with a default value of 98 gCO2eq/kWh.
Renewable energy sources (e.g., solar, wind, hydro): produces very low or zero direct CO2 emissions.

Potential results of upgrading gas turbine with electric solutions

Tooltip
Technical assumptions and sources:
  • Assumes a gas turbine open cycle is used.
  • Applies to one turbine at a time.
  • Applies variable speed drive system’s standard efficiency at 96%*​.
  • CO2 emissions savings and CO2 emissions tax savings are calculated based on both direct emission reductions and indirect carbon impact of electricity power generation.​
*Average value of transformers, drives, motors and gearbox.​

≈ yearly CO2 emissions of electric car in Europe

Tooltip
This calculation assumes an average EU car emits 1.3 tons of CO2 per year, based on 2022 European Union (EU) new cars and vans fleet averages (108.2 gCO2/km and 12,000 km/year). Actual emissions may vary by vehicle type, fuel efficiency, driving habits, location and other variables.
