Automated Demand Response (ADR) : Pearlstone Energy uses Honeywell’s proven and trusted ADR technology to enable your buildings to participate in a variety of Demand Management programmes. We install the necessary technology and management system at zero cost for our clients. ADR allows electricity consumers to temporarily switch off or turn down the non essential electricity, or turn on standby generators, and get paid to do so.

Balancing Service: National Grid procures Balancing Services in order to balance demand and supply and to ensure the security and quality of electricity supply across the GB Transmission System.

Building Management Systems (BMS) : A BMS refers to a computer-based control system installed in buildings to help monitor and control the vital functions of the building. These can range from the ventilation and lighting systems to security and power.

Capacity Market Auction : is a bit like an energy guarantee. It works by making sure that there is enough capacity available to meet peak electricity demand in the future. The first stage of this process has been to estimate how much capacity will be needed in 2018/19. Electricity providers have then bid into this capacity auction, promising if they win a contract that they will be available to provide electricity when needed. In return, they will receive a steady payment on top of the electricity that they sell.

Corporate Social Responsibility (CSR) : CSR is defined by the European Commission as “the responsibility of enterprises for their impacts on society”. The Commission encourages that enterprises “should have in place a process to integrate social, environmental, ethical human rights and consumer concerns into their business operations and core strategy in close collaboration with their stakeholders”.

Demand Response : Electricity cannot be stored on a large scale. Traditionally to meet periods of  increased demand, utilities generate more electricity, putting greater pressure on resources. But with Demand response, users are paid for reducing their consumption and allowing the supply to be utilised elsewhere. It is typically cheaper and easier to procure electricity supply via Demand Response management than traditional generation.

Demand Side Response (DSR): is the scheme where customers are incentivised financially to lower or shift their electricity use at peak times. This will help manage load and voltage profiles on the electricity network.

Demand Side Balancing Reserve (DSBR) : is a new service designed to support National Grid in balancing the system in the unlikely event that there is insufficient capacity in the market to meet demand. The service is targeted commercial and industrial energy consumers who volunteer to reduce demand between 4 and 8 pm on winter weekday evening in return for a payment.

Distribution Network Operator (DNO) : Own and operate the distribution network of towers and cables that bring electricity from our national transmission network to homes and businesses. They don’t sell electricity to consumers. This is done by the electricity suppliers.

Distribution Use of System (DUoS) Charge : This charge covers cost of receiving electricity from national transmission system & feeding it directly into homes & businesses through regional distribution DNOs.

Electricity Market Reform (EMR) : The reformed electricity market is designed to deliver the greener energy and reliable supplies that the country needs, while minimising costs for consumers in the long term, and, to ensure we build a cleaner, more sustainable energy mix. EMR is designed to i) decarbonise electricity generation, ii) keep the lights on and iii) minimise the cost of electricity to consumers.

Energy Savings Opportunity Scheme (ESOS) : This is a mandatory energy assessment and energy savings identification scheme for large organisations in the UK.  For the first stage of the scheme, participants must notify the Environment Agency that they have complied with ESOS by the 5th December 2015.

Flexible Load : Buildings and some facilities are able to reduce or turn off the electricity to various devices for short periods of time without negatively affecting the building’s performance or comfort conditions for its occupants. This is known as the building’s “Flexible Load”.

Industrial Emissions Directive (IED): is a EU directive which commits European Union member states to control and reduce the impact of industrial emissions on the environment.

Large Combustion Plant Directive (LCPD) : A European Union directive that applies to fossil-fuel power stations within member states and specifies emission limits for sulphur dioxide, nitrogen oxides, and dust. The result is a reduction in energy produced by these power stations.

National Grid (NG) : is the high-voltage electric power transmission network in Great Britain, connecting power stations and major substations and ensuring that electricity generated anywhere in England, Scotland and Wales can be used to satisfy demand elsewhere.

OpenADR Gateway : Honeywell’s technology developed to standardize fast and reliable automated demand response.

Transmission System Operator (TSO) : is an entity entrusted with transporting energy in the form of natural gas or electrical power on a national or regional level, using fixed infrastructure.

Triad Charge The “triad” system is the means by which industrial & commercial consumers pay for the electricity transmission network in GB;  typically from Nov to Feb. These peak demand times are known as ‘Tri­ads’.

Short Term Operating Reserve (STOR) : is a service for the provision of additional active power from generation and/or demand reduction. STOR is needed because at certain times of the day National Grid needs reserve power in the form of either generation or demand reduction to be able to  deal with actual demand being greater than forecast demand and/or plant unavailability.

Sustainable Development : is the kind of development that meets the needs of the present without compromising the ability of future generations to meet their own needs.

System Frequency: is a continuously changing variable that is determined and controlled by the second-by-second (real time) balance between system demand and total generation. If demand is greater than generation, the frequency falls while if generation is greater than demand, the frequency rises.

Virtual Power Plant (VPP) : A VPP can be defined as a system that relies upon software systems to remotely and automatically dispatch and optimise generation, demand-side, or storage resources (including plug-in electric vehicles and bi-directional inverters) in a single, secure web-connected system.
