Demand Response

Find out our how clients are earning significant revenues annually.

Frequency Response

The UK’s TSO (National Grid) has a requirement to maintain grid frequency within a narrow band around 50Hz. However, in reality the grid frequency typically fluctuates slightly from 50Hz as supply and demand are balanced. To help keep frequency as close to 50Hz as possible we provide balancing services to National Grid using the portfolio of assets under our management. Frequency response is the first demand response programme that is used to keep the grid in balance and is typically a high-value service generating a strong revenue.

The Benefits to You

The benefits of enrolling in one of the demand side response  programs in the UK are large financial returns. Frequency Response programmes are the highest paid demand response programs. Implementation of these UK demand response programs comes at no risk to site operations. KiWi Power ensure, through diligent site surveys and constant communication with on site contacts, that there is never any risk to production, comfort, or any business process.

The Programme

Frequency Response is a premium grid service and is offered to commercial and industrial clients who are able to rebalance sudden changes in supply and demand which have a negative impact on grid frequency.
There are two types of Frequency Response programme: Static and Dynamic. Static Frequency Response refers to activating a fixed capacity (for example: 2MW) for a fixed duration when the frequency reaches a threshold. On the other hand, Dynamic Frequency Response refers to measuring frequency at all times and activating capacity (MW) that is proportional to any frequency deviation, positive or negative, from 50Hz.

Static Frequency Response

Any client with assets that can react to an automatic call from National Grid, through KiWi Power, within 30 seconds and hold that drop for 30 minutes can participate in this programme. Please see table below for some of the proven assets for this demand response program broken out by industry:
Assets are called to react when nationwide grid frequency drops to 49.7 Hz or raises to 50.3 Hz. Tenders with National Grid are held on a monthly basis in an enduring market allowing KiWi to tender your capacity at the earliest possible opportunity.

Dynamic Frequency Response

National Grid’s most lucrative demand response program in the UK, Dynamic Firm Frequency Response, is more niche than its static counterpart (fewer assets are suited to the programme) but will pay the client significantly higher revenues. To participate, a client’s asset must be able to respond to fluctuations in Grid Frequency in real time. Without the set trigger points of Static FFR this Demand Response Programme is almost continuous with your assets reacting around 80% of the time, ensuring UK Grid Frequency remains stable. While Static FFR requires full delivery for a small number of events, Dynamic FFR requires a small response for a large portion of the year.

Case Study

Commercial property manager CBRE introduced one of the world’s largest financial institutions to KiWi Power. The bank serves individual consumers and corporations with a full range of banking, investing, asset management and other financial and risk management products and services. Their on-site diesel rotary uninterruptable power supply (DRUPS) system made them a perfect candidate for the National Grid’s frequency response programs. Read more here.
