The importance of distribution businesses conducting Demand Side Response (DRS) has been recognised in the regulation of energy networks. The NTVV project seeks to better understand the needs of business customers, with particular focus on the role DSR can play in managing distribution network constraints.
This document outlines the steps that were taken to establish the necessary tools related to SDRC 9.8a 2&3 – namely “Demand Side Response evaluation” and “Network Controlled Demand Side Response evaluation & energy efficiency”.

The NTVV project has proved that we can engage commercial customers in demand response conversations, encourage them to take part is DSR and in many occasions, we have learnt that there are other benefits and offerings to customers other than purely financial incentives that attract interest. The NTVV project has signed 30 buildings on to our DSR programme without any direct financial incentive however; examining the on-going incentive structure is a key learning for the project over the next two years. Historic learning from the project has told us to simplify the commercial offering into a single document to reduce legal review.

This learning report analyses 83 events in all from 11 customers and during this testing phase, 2 events were held that aggregate all customers at the same time. The average ADR load reduction achieved was 11.3% and of the 83 events held, 73% were successful.

Installation of ADR has proved to run very smoothly and the learning from US experience of established installations has proved invaluable however, obtaining a communications link in the customers building proved difficult. Following these difficulties, Honeywell have decided to install GPRS wireless communications into 2 buildings to date, the key learning from this to ensure install does not get slowed in any way is to make the decision to switch to GPRS as soon as it appears a fixed communications link may be problematic to obtain.

With regards to the wider industry, it is recognised that industry parties would benefit from increased visibility for DSR actions led by the DNO, mainly if the notification can happen prior to Gate Closure in the Balancing Market. However, the market would have to evolve to permit these notifications to be done in an automated way, via standard industry flows for instance, to allow for better optimisation of resources from all parties
This document meets the New Thames Valley Vision (NTVV) project deliverable in relation to SDRC 9.8a 2&3, and outlines the next stages of development that will provide further information and learning from the project.
