Limejump’s ‘big data’ systems help clients become involved with the Demand Side Balancing Reserve (DSBR) which was piloted over the winter months of 2014 and 2015.


A data-driven revolution is taking place in the energy market. Companies across the UK are switching to the innovative Demand Side Balancing Reserve (DSBR) service, where National Grid pays businesses to use less energy at peak times. Meet Limejump, pioneers in this dynamic new marketplace.

Limejump’s mission is to transform energy with data. From its offices in central London, this pioneering start-up uses cutting edge software and technology to help businesses across the country take part in balancing the National Grid.

A perfect match

Limejump’s partnership with National Grid is a perfect match for this cloud-based platform, which was created to help businesses drive electricity savings and generate new revenue streams by taking part in demand response programmes through ‘a virtual power plant’.

Piloted last winter, DSBR is National Grid’s innovative new emergency back-up scheme. It will be active between 4pm and 8pm on weekday evenings between November and February.

Erik Nygard, who co-founded Limejump in January 2014, said: “DSBR is the most flexible demand response product that National Grid offers. Even small businesses can participate in the programme as long as they have a half-hourly smart meter.”

Making a difference

“Limejump works with organisations across all sectors, from schools to large manufacturing facilities. Individually, many of these customers use smaller amounts of energy which do not have much of an impact compared to large industrial sites. However, by coming together and joining the Limejump ‘virtual power plant’, companies are able to make a difference in helping to balance the electricity grid – competing directly against large power plants.”

Limejump’s software and technology connects to customers’ smart meters and control devices. The intuitive platform is powered by ‘big data’ – from live and forecast weather data, to relevant market prices, to customer tariff information – helping businesses proactively manage their power demand or switch to their own on-site generators at peak times.

As well as helping to balance the National Grid, Limejump is confident that being part of DSBR brings clear commercial benefits to companies who sign up.

Commercial benefits

Erik Nygard said: “This is an easy way for companies to generate new revenue. We know the extra income generated from participating in DSBR has a positive impact on the businesses taking part. And because this is an exciting new way to be clever and agile with your energy demand, being part of DSBR is compelling for customer engagement. It’s a great story to tell to your customers about what you are doing as a modern, progressive and greener business.”

National Grid worked with 12 companies during the pilot. Many were large consumers of energy. It now wants more companies, large and small, to get on board.

When called on by National Grid at peak times, the Limejump platform sends out a signal via email, text or a voice call, informing customers what steps they need to take; either managing their power demand or switching to their own on-site generators. In many cases Limejump will automatically control equipment based on National Grid signals, making it even easier for customers to take part.

Erik Nygard said: “The general feedback from our customers is that they are given enough time to plan their processes in time for participation, and considering the financial incentives, it is worth the effort. This is not the case with many other programmes that require fast responses, often within minutes.”

A real understanding

“Also, Limejump allows each customer to validate their participation and keep track of all demand response events. Through these analytics customers can build up a real understanding of their energy usage – something many customers have never experienced before.”

“The DSBR initiative enables businesses of all sizes to take a proactive role in creating the electricity system of the future, by playing alongside power stations to help balance the UK electricity system. It is all about transforming energy with data – using our software and technology to deliver cutting edge solutions that enable customers to manage their energy usage or generation with total flexibility.”
