## Which power plant has the maximum efficiency?

Renewables Hydro turbinesRenewables.

Hydro turbines, the oldest and the most commonly used renewable energy source, have the highest efficient of all power conversion process..

## What is meant by efficiency of a power station?

The thermal efficiency of the electrical power generation is defined as the electrical energy produced divided by the total energy released by the fuel consumed. The waste heat of the power cycle goes into cooling water and the exhaust gases that exit from the power plant stacks.

## What is the approximate percentage of efficiency in thermal power plant?

The energy efficiency of a conventional thermal power station is defined as saleable energy produced as a percent of the heating value of the fuel consumed. A simple cycle gas turbine achieves energy conversion efficiencies from 20 to 35%.

## What is the efficiency of a power plant?

To express the efficiency of a generator or power plant as a percentage, divide the equivalent Btu content of a kWh of electricity (3,412 Btu) by the heat rate. For example, if the heat rate is 10,500 Btu, the efficiency is 33%. If the heat rate is 7,500 Btu, the efficiency is 45%.
