Frequently Asked Questions
Aggregator – OakTree Power is a DSR Aggregator. We are a new type of energy service provider, providing Demand Side Response (DSR) to the grid operators such as National Grid, when needed to manage electricity supply issues. As National Grid is managing the supply network on a national basis, it has a minimum DSR provision threshold of 3MW. However, this 3MW can be aggregated. Our digital technology enables us to adjust the electricity consumption of our customers’ facilities across the country in concert to meet National Grid’s minimum thresholds, thereby monetising each customer’s Flexible Load which on an individual facility basis would be worthless.
BMS – Building Management System: is a computer-based control system installed in buildings that controls and monitors the building’s mechanical and electrical equipment which may include ventilation, lighting, power systems, fire systems, and security systems. The OakTree Power box-on-the-wall interfaces with the BMS to deliver DSR events.
Carbon Neutral – this refers to achieving Net Zero carbon dioxide emissions. This can be done by balancing emissions of carbon dioxide with its removal or by simply eliminating emissions from society. Going beyond this, it is possible to become carbon negative, where an entity’s carbon footprint is less than neutral. This can be achieved through processes that have a net effect of removing carbon dioxide from the atmosphere such as carbon capture but more typically is achieved through carbon offsetting projects, such as tree planting. OakTree Power’s Green DSR solution provides carbon emission reductions unobtainable elsewhere and additional to those obtained from energy efficiency measures. In this way it can reduce the number of offsets your organisation needs to purchase to get to Net Zero.
Decarbonisation – the reduction of carbon dioxide emissions through moving away from carbon emitting sources and achieving a lower output of greenhouse gasses into the atmosphere. The UK strategy to decarbonise the economy has resulted in the move to renewable energy generation in place of coal-fired power stations and a switch from petrol and diesel cars to EVs.
DUoS – DUoS is part of your overall electricity bill and includes both a fixed charge (mainly based on your contracted connection capacity) and a variable charge that applies to every kWh of consumption. DUoS covers the cost of installing and maintaining local electricity distribution networks, which transport electricity from the National Grid to your business.
Flexible Load – The degree of adjustment we can achieve from your facility’s electricity consumption.
Load Adjustment Strategy – this is the pre-agreed plan for consumption reduction, programmed into the Building Management System and initiated by the box-on-the-wall when the signal is received to implement a DSR event.
Net Zero – Means achieving a balance between the greenhouse gases put into the atmosphere and those taken out. This state is also referred to as carbon neutral; although zero emissions and zero carbon are slightly different, as they usually mean that no emissions were produced in the first place. The UK has a legal commitment to be carbon neutral by 2050 and many organisations are following this lead by setting their own Net Zero targets
NGESO – National Grid ESO is the electricity system operator for Great Britain. It moves electricity around the country second by second to ensure that the right amount of electricity is where it’s needed, when it’s needed – always keeping supply and demand in perfect balance.
TNUoS – charges applied to recover the cost of installing and maintaining the transmission system in England, Wales, Scotland and Offshore. Depending on your tariff, OakTree Power can help reduce some of these costs as part of the DSR management process.
