Aggregators
Aggregators allow smaller storage or generation asset owners to collectively access grid balancing services

Knowledge Base
Agreed Supply Capacity
Your agreed supply capacity, or ASC, is the amount of electricity that your DNO must provide you with at all times. It is also referred to as Supply capacity or Authorised Supply Capacity.
Air and Ground Source Heat Pumps
Air and ground source heat pumps are a low carbon heating technology that draws latent heat from a building's surroundings
Base Load & Peak Load
Demand for electrical power varies throughout the day. Base load refers to the minimum level of power required across a set 24-hour period, primarily from equipment and appliances that require consume power at a consistent rate.
Battery Energy Storage
A battery energy storage system (BESS) is a device that allows energy to be stored and released when needed
Behind The Meter
Behind the Meter refers to energy equipment and systems that are located on-site, in that they are behind the meter that is used by your utility provider to calculate the amount of energy you have drawn from the grid.
BEIS
The Department for Business, Energy and Industrial Strategy (BEIS), is the department of government responsible for business, industrial strategy, science, research, innovation, energy & clean growth and climate change.
Biomass
Biomass boilers use wood pellets or other organic material as a replacement for fossil fuels, but its green credentials have been called into question
Blackouts and Brownouts
A blackout is generally the most significant form of power disruption, a large-scale service interruption that seems your grid supply cut off. Blackouts can be caused by a variety of outside factors, such as severe weathers or unexpected spikes in demand.
BREEAM
Building Research Establishment Environmental Assessment Method (BREEAM) is the world’s most established method of assessing, rating and certifying the sustainability of buildings.
Building Energy Management System (BEMS)
Building Energy Management Systems (BEMS) are integrated systems for monitoring and controlling energy-related infrastructure and equipment within a building, such as heating, ventilation and air conditioning, lighting, on-site generation and other technologies.
Capacity Market
The Capacity Market is a mechanism used by National Grid to ensure that additional generation capacity is available to meet peak demand
Carbon Capture and Storage
Carbon Capture and Storage allows carbon emissions from heavy industry to be captured and stored rather than being released to the atmosphere
Climate Change Agreement (CCA)
A CCA is a voluntary agreement that allows businesses in high energy industries to receive a discount on the Climate Change Levy (CCL), an energy tax to non-domestic consumers in the UK, chargeable to both electricity and gas supplies.
Climate Change Levy
The Climate Change Levy (CCL) is an environmental tax on business energy. Introduced in April 2001, the CCL is designed to incentivise businesses to be more energy efficient in how they operate and reduce their overall emissions.
Combined Heat and Power
Combined Heat and Power (CHP), also known as co-generation refers to the process of capturing the heat generated as a by-product of electricity generation for use elsewhere
Commodity and Non-Commodity Costs
Energy bills for end users are broadly split into two elements; commodity and non-commodity costs
Corporate Power Purchase Agreement (CPPA)
Corporate Power Purchase Agreements allow an end user to purchase renewable energy directly from a generator over an extended period
Demand Side Response
The rapid change in how the UK generates and uses electricity has made balancing generation with demand an increasingly complex challenge.
Digital Twins
Digital twins are digital representations of real-world systems that can be used to test, diagnose and optimise those systems in real time
Distributed Generation
Historically, the UK’s National Grid was designed with central dispatch in mind. This meant that electricity was centrally generated using large, typically coal-fired power stations, then dispatched to end users. The UK’s development of this model was replicated worldwide, and for decades it provided us with an extremely reliable energy system.
Distribution Network Operators
Distribution Network Operators (DNOs) own and operate the energy distribution networks that connect a site to the national grid. Each holds a licence to distribute energy in the UK
DUoS and TNUoS
The Targeted Charging (TCR) Review was announced in 2017 by Ofgem as a review of how customers are charged to cover the cost of distribution and transmission network operators.
