Guinness World Records has named the Chubu Electric Nishi-Nagoya power plant Block-1 in Japan – powered by GE’s 7HA gas turbine – the world’s most efficient combined-cycle power plant, based on achieving 63.08 percent gross efficiency.
What is the most efficient type of power plant?
And when it comes to efficient natural gas-fired plants, there are none better than EDF Bouchain. The 605-MW unit has been recognized by Guinness World Records as the most-efficient combined cycle power plant in the world, with a third-party verified net efficiency of 62.22%.
How efficient are power stations?
The efficiency of electricity and heat production from conventional thermal power plants improved between 1990 and 2009 by 5.5 percentage points (from 45.4% in 1990 to 50.9% in 2009). Between 1990 and 2005, the improvement was even greater at 7.0 percentage points (from 45.4% in 1990 to 52.4% in 2005).
Which power plant has lowest running cost?
Explanation: Hydroelectric power plant has lowest running cost because it does not needs any fuel and can be operated by few number of persons. Nuclear gas and thermal power plant requires fuels also the handling cost of fuels is added with the total cost.
Which is more efficient gas turbine or steam turbine?
Steam turbine
Turbines produce direct rotary motion and are far more compact and weigh far less than reciprocating engines and can be controlled to within a very constant speed. As is the case with the gas turbine, the steam turbine works most efficiently at full power, and poorly at slower speeds.
What is the first power station in the world called?
In 1882 the world’s first coal-fired public power station, the Edison Electric Light Station, was built in London, a project of Thomas Edison organized by Edward Johnson. A Babcock & Wilcox boiler powered a 93 kW (125 horsepower) steam engine that drove a 27 tonnes (27 long tons) generator.
What are the 4 types of electricity?
- Static Electricity. Static Electricity is nothing but the contact between equal amount of protons and electrons (positively and negatively charged subatomic particles). …
- Current Electricity. Current Electricity is a flow of electric charge across an electrical field. …
- Hydro Electricity. …
- Solar Electricity.

Why are power plants more efficient in the winter?
Here’s why winter’s colder temperatures make energy production at nuclear and fossil plants more efficient. “To run a plant at maximum efficiency you have to generate a lot of heat and then you have to remove it quickly so the steam cycle can start all over again.” …
How efficient is wind energy?
Wind energy, also known as wind power, is the means of harnessing wind and turning it into electricity. The average wind efficiency of turbines is between 35-45%.
How efficient are coal fired power stations?
With coal-fired power plants achieving an average 33 percent efficiency, it’s crucial to build advanced HELE plants to reduce global carbon emissions. With low carbon a priority in energy generation, it is imperative to develop a more efficient, lower-emissions technology for coal.
Which power plant has longest life?
Currently, the longest serving reactor ever is located in the United States, at the Oyster Creek Nuclear Power Plant in New Jersey, which started operations in 1969, which like it’s cousin on the Kola Peninsula, is operating on an engineered lifespan extension until 2018.
Which power plant is most reliable Mcq?
Explanation: Nuclear Power Plant is most reliable of all energy sources due to the following facts: The Powerful nuclear fuel: One kg on nuclear fuel can generate electric power as much as a 1000 kg or even 5 times more coal can generate.
How efficient is fossil fuel power plant?
Typical thermal efficiency for utility-scale electrical generators is around 37% for coal and oil-fired plants, and 56 – 60% (LEV) for combined-cycle gas-fired plants. Plants designed to achieve peak efficiency while operating at capacity will be less efficient when operating off-design (i.e. temperatures too low.)
What is the most efficient car engine?
To date, the most thermally efficient automotive internal combustion engine belongs to Mercedes-AMG’s Formula 1 team, with an efficiency of 50 percent; AMG hopes the F1-derived engine in the Project One street-legal supercar will achieve 41-percent thermal efficiency, which would make it the most thermally efficient …
What is the most efficient turbine?
Today we announced that the Chubu Electric Nishi-Nagoya power plant Block-1 – powered by GE’s 7HA gas turbine – has been recognized by GUINNESS WORLD RECORDS™ as the world’s Most efficient combined-cycle power plant, based on achieving 63.08 percent gross efficiency.
Why is steam turbine efficiency so low?
A decrease of the steam pressure pt in the condenser causes a decrease of the steam condensation temperature and consequently increases the temperature difference in the cycle. The efficiency of steam-turbine units increases when regenerative extraction of steam from the turbine is used.
