Conclusions and future work
The trial has demonstrated the functionality of a DDSM system and
provided an initial indication of the network and customer benefits.
The next step required for progression towards Business As Usual (BAU)
deployment is to trial dynamic scheduling and control.
A large-scale roll out to 750 homes in Shetland through SHEPD’s NINES
project will enable this.
Allow SHEPD to determine the value of DDSM to DNO’s.

Honeywell Automated Demand Response
Overview
• Pilot demonstration of Honeywell's Automated Demand Response (ADR)
solution
– Enable DNO to reduce non-domestic demand at strategic points on the network
– Load shed triggered via signal to existing building management systems
• Benefits
– Match electrical distribution needs to changing customer demand profiles
– Provide visibility of customer usage
– Re-engage with customers to enhance future planning
Trialling method
• Deployed at 3 customer sites:
– Bracknell & Wokingham College
– Bracknell Forest Council
– Honeywell House
• Sites: >200kW use, DR programming change to BMS, individual load
shed event participation or opt out
• Test capability of ADR to:
– Produce an aggregated figure of despatchable demand
– Reduce/shift peak loads
Trial load shed event – single site
Aggregated load shed eventSite Average kW shed
Honeywell House 70 kW
Bracknell & Wokingham College 56 kW
Bracknell Forest Council 11 kW
Aggregated load shed eventHoneywell House 75 kW
Aggregated load shed eventBracknell & Wokingham College 81 kW
Aggregated load shed eventBracknell Forest Council 11 kW
Using the information regarding the steps and time taken to acquire
customers we have calculated the cost it took to get to sign up
stage
Although a limited sample, it provides a valid indicative cost to a
DNO associated with recruitment for this type and scale of trial.

• Modelling was performed to extrapolate results in more detail.
• Began to understand how
ADR can improve network
observability on the distribution
network
Value to a DNO
• Capable of shedding load in commercial properties by
communicating with the existing BMS
• Load shed can be triggered simultaneously to perform an
aggregated load shed
• maximum aggregated load shed of 137kW
• Streamlined Customer Engagement is Key
