Power generation

The term 'power generation' describes the process of generating electrical power. Types of power generation include:

• Fossil fuel thermal energy such as coal or natural gas.
• Biogas energy.
• Geothermal energy.
• Hydroelectricity.
• Wind energy.
• Solar thermal energy.
• Tidal energy.
• Photovoltaics.
• Nuclear energy.
• Chemical energy generated from fuel cells, batteries, and so on.

Power stations are normally located away from centres of population where fossil fuels are abundant or good transport links exist. Many of these locations are well away from the towns and cities where the electricity is used and hence there is a need for electricity transmission and distribution.

The national power supply network is managed by four types of organisation:

• Generators - responsible for producing the electricity.
• Suppliers - responsible for supply and selling electricity to consumers.
• Transmission network - responsible for the transmission of electricity across the country.
• Distributors - those who own and operate the local distribution network from the national transmission network to homes and businesses.

Microgeneration is the local production of power on a very small scale in comparison to the typical output of a power station.

Consumers can qualify for an ‘export tariff’ by selling surplus electricity back to their supplier. Allowable technologies are:

• Solar photovoltaic panels.
• Wind turbines.
• Water turbines.
• Anaerobic digestion (biogas energy).
• Micro combined heat and power (micro-CHP).

NB Net Zero by 2050, A Roadmap for the Global Energy Sector, published by the International Energy Agency in May 2021, suggests that power generation: ‘Refers to fuel use in electricity plants, heat plants and combined heat and power (CHP) plants. Both main activity producer plants and small plants that produce fuel for their own use (auto-producers) are included.’
