Get Energy Efficiency In The Power Grid

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.

A simple cycle natural gas power plant efficiency rate tends to be the lower, ranging from 33% to 43%. On the other hand, a combined cycle power plant's efficiency can reach upwards of 60% because it captures and uses the plant's hot exhaust gases to spin a secondary turbine, which generates more electricity.

In a coal-fired power generator only 40% of coal's thermal energy is converted to electricity. There is 2,460 kWh of electricity generated per ton of coal. A standard 500 megawatt coal power plant produces 3.5 billion kWh per year, which is enough energy to power 4 million light bulbs all year.

Power supply efficiency is the amount of the actual power delivered to the components divided by the electrical power drawn from the mains supply socket. If a power supply with 50% efficiency is required to provide a 50W power to a load, it will draw 100 W from the wall.

The efficiency of a large electrical generator is typically 99%. From the gross output without electrical power consumed by the station auxiliaries and the losses in “generator transformers” it is possible to obtain the net value.

Reliable operation – A reliable power grid has the ability to withstand sudden electric system disturbances that can lead to blackouts. Resource adequacy - Generally speaking, resource adequacy is the ability of the electric system to meet the energy needs of electricity consumers.

The overall efficiency from primary energy to delivered work is about 33% for energy in the US. Almost 2/3 of the energy that is consumed as primary energy is released as waste.

Energy efficiency is the use of less energy to perform the same task or produce the same result. Energy-efficient homes and buildings use less energy to heat, cool, and run appliances and electronics, and energy-efficient manufacturing facilities use less energy to produce goods.

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%.

Some modern nuclear plants may be able to achieve 45% efficiency. Coal power plant efficiency is very similar to nuclear, with a typical U.S. coal plant operating at 32% to 33% efficiency. There are two different types of natural gas power plants — simple cycle and combined cycle.

The U.S. Energy Information Administration (EIA) estimates that annual electricity transmission and distribution (T&D) losses averaged about 5% of the electricity transmitted and distributed in the United States in 2018 through 2022. EIA has estimates for total annual T&D losses in the State Electricity Profiles.
