Intelligent energy use made simple

Haven Power helps you cut through the complexity of Demand Side Response (DSR) to work out how and where your business can benefit.

Traditionally, generators provided the market with its flexibility because they could turn production down or up to balance the network and help meet peaks in demand. For example, during the recent England vs Columbia football match, National Grid reported a peak in demand of 1200MW – which is the same as 400,000 kettles being turned on! However, thanks to Demand Side Response (DSR) schemes large businesses can also now earn revenue through flexible usage.

There are multiple options available when it comes to choosing a Demand Side Response (DSR) scheme for your business. To help simplify the complexity, David Mvula – Energy Services Solutions Manager at Haven Power – explains the two main types:

1. Avoiding peak-time costs

“The first thing to understand is that there are two main ways to benefit from DSR. The first – and easiest to implement – is simply to avoid peak-time electricity costs.”

“Businesses might be able to achieve this on their own by switching production times around. Alternatively, you can turn off your energy-hungry equipment during the usual peak period between 4pm and 7pm on weekdays. Over time, these simple changes to how you work could reduce your electricity costs by up to 15%. It doesn’t require commitment or contracts – just communication across the business.”

2. Schemes administered by National Grid

“As well as avoiding peak-time costs, businesses can take part formally in a range of DSR schemes run by the system operator National Grid. These generally reward participants for changing the ways – or the times of day – they use electricity; usually to help balance the network. They tend to break down into Frequency Response services, and Reserve services.

Frequency Response services typically require businesses to commit to switching their electricity usage in less than a second to help balance the network. Because of this need for immediacy, Frequency Response requires automation.

Reserve services provide extra power to the Grid at times of peak demand, either in the form of demand reduction or increased generation. Reserve services include the Fast Reserve and the Short Term Operating Reserve (STOR).

The Fast Reserve is a 24/7 commitment, usually requiring providers to be ready to contribute extra generation for periods of five minutes at a time, ten times a day.

STOR gives businesses the opportunity to profit from supporting the power network. It is typically used in two daily ‘windows’ – morning and evening. It gives participants up to several hours’ notice that they might need to turn on more generating capacity. This makes it very attractive for businesses that self generate, because they can turn the power over to the Grid through STOR at times when demand – and prices – are at a peak.

Other Reserve services include Demand Turn Up, which requires businesses to commit to turning up their electricity usage when renewable output is high and demand low – such as summer afternoons or overnight.

Used wisely, DSR has the potential to help businesses of all sizes benefit financially from changing the ways they use power.”
