Energy Generation and Distribution
Energy generation and distribution is a sub-theme of resource management
Energy generation and distribution is the process through which power, generally electricity and gas, is produced by utility companies and delivered through a transmission grid by distribution network operators (DNOs) to end users (industrial and domestic consumers). Generation can be from 'conventional' sources (coal, gas and nuclear power stations) and from renewable sources (water, wind, biofuels, PV and solar).
Generation is conventionally large scale, but is becoming more localized through small industrial and domestic installations. Distribution is predominantly through the National Grid (gas and electricity).
Management of the generation and distribution, particularly of electricity, will be strongly influenced by the emerging development of smart grids.
Standards in energy generation and distribution ensure the provision of a consistent, flexible and reliable power supply to the consumer with appropriate safety measures and accurate, timely customer billing.
Standards within energy generation and distribution can be divided into three main categories – grid and infrastructure, conventional energy generation and renewable energy.
Grid and Infrastructure
Grid and infrastructure covers:
- The quality specification of the power supply (gas quality and electricity) at all stages
- The structures, materials and components used for the distribution grid for overhead electrical lines, towers and gas pipelines
- Allowable variations of the distributed and delivered end product.
Standards for grid and infrastructure provide:
- Guidance to enable connection of generating plants to the UK's electricity distribution networks
- Power line communication systems for carrier systems operating over electricity grids which provide a platform for commercial interoperability for all types of residential, commercial and industrial networks
- Consistent requirements and testing of electric metering equipment and communications systems for network

Conventional Energy Generation
Energy that has been used historically is known as conventional energy. Conventional energy is essentially produced from fossil fuels — coal, natural gas and oil — and nuclear energy.
Standards for conventional energy generation provide specifications and testing on received raw materials and products and the safety of supply, operation and distribution.

Renewable energy represents a huge opportunity to channel naturally occurring, inexhaustible resources - wind, solar, geothermal, hydroelectric, and biomass – to meet our energy demands. Technological innovation, supported by standards, has increased the reliability of infrastructures and installations, enabling the production of clean, safe, sustainable energy.
Standards for renewable energy:
- Provide design requirements
- Guidance on planning and installation of energy generation systems and larger infrastructure projects such as power grid connection
- Test methods to measure power performance
- Safety requirements
Renewable energy standards are developed by experts for industry, reflecting stakeholder needs to provide requirements and guidance that enable the development of more efficient renewable energy projects, driving down costs.

Electrical Energy Storage Systems
Electrical energy storage (EES) is one of the key technologies to cut peak energy demand, maintain reliability and improve power quality. EES technologies have proved their unique capabilities in coping with these critical characteristics of electricity, and will become indispensable in emerging markets with the integration of renewable energy, to achieve CO2 reduction and provide a vital component of Smart Grids.
Standards are currently in development for 2017 publication to provide planning and installation requirements for electrical properties of grid operation and energy and power supply security. Also in development are standards on specifying unit parameters and test methods for EES systems, guidance on environmental issues, and safety considerations.
