Energy transition explained

The process of capturing carbon dioxide before it enters the atmosphere, transporting it and storing it.

The process of removing, capturing and storing carbon dioxide from chemical processes, combustion emissions or directly from the atmosphere in order to tackle climate change. Carbon sequestration can be natural (e.g. carbon sequestration through forestry) or artificial (e.g. carbon capture technology).

Large scale production of electricity usually from fossil fuels, nuclear or hydro, at centralised locations reaching the consumers through a high voltage transmission network.

Production of heat energy and electrical or mechanical power from the same fuel in the same facility. A typical cogeneration facility produces electricity and steam for industrial process use.

A term which means all of the residents in a building, neighbourhood or local area collaborate together to ensure that locally generated renewable electricity is consumed within the collective.

Also known as cogeneration. The concurrent production of electricity and useful thermal energy (which can be used for heating or cooling) from a single source of energy. CHP can be located at an individual facility or building, such as hospitals, universities or commercial centres, and in district heating schemes.

Capacity for the interconnection of platforms, systems and applications.

The flow of energy between difference sectors that were previously separate as they used discrete fuel sources. For example, the shift to EVs is a cross vector of the transport sector and the electricity sector.

The average total downtime per customer-interruption.

The average number of interruptions per customer interrupted per year.

The average number of minutes that a customer has their supply interrupted.

This is a technique to break down electricity consumption to the level of individual appliances. For example, if the consumption in a given period of a home was 1000kWh, demand disaggregation might enable the homeowner to see that 200kWh was used for recharging their EV, 500kWh by their heat pump, 100kWh by their dishwasher, 50 kWh by the washing machine, and the rest by lighting & electronic appliances etc. The disaggregation enables consumers to better understand their energy consumption and energy bills, and energy suppliers to forecast energy demand and provide advice their customers.
