Scope and Objectives
Please describe the scope and objectives of the Project should be clearly defined including the benefits which should directly
accrue to the Distribution System.
Please give details of how the DNO will evaluate whether the Project has been successful.
This section should set out the Method or Methods that will be trialled in order to solve the Problem. The type of Method
should be identified where possible e.g. technical or commercial.
There is also little data available as to what appliances this can be applied to and which devices
will deliver the best demand reduction when an event is instigated.
Consumer engagement will be key to the acceptance of DDSR, however it is currently unclear as
to what attitudes are to direct load control, and levels of incentives required to change behaviours
In the future, in is envisaged that smart meters will facilitate DDSR, although a full deployment is
not expected till 2020. Subsequently this trial will take place without utilising smart metering
infrastructure to allow learning to be attained quicker.
The Energy Saving Trust (EST) has been approached as a project partner to deliver the consumer
recruitment and engagement aspects. The project will look to utilise their data base of customers
who have registered an interesting in taking part in trials, as well as links to housing associations.
Two hundred customers will be recruited by EST to participate in the trial allowing several
statistically representative groups to be created, and a number of incentive scenarios trialled.
Greenlet have been selected by EST as the technology supplier due to their experience in this
area, and the applicability of the products. Each property will receive a number of plugin Greenlet
devices which sit between the plug socket and the appliance to be controlled. Each unit can be
installed by the customer, and will collect data on the appliances whilst allowing load control
signals to be actioned. The Greenlet plugs create a communications link with a gateway device
connected to a domestic broadband service. A head-end software system will be used to schedule
the load control events and send signals to the Greenlet plugs to control the loads. A web portal is
available to customers to monitor energy usage and help manage appliances remotely.
To incentivise customers to participate, a range of financiall incentives will be developed and
trialled. Data will be collected through the Greenlet devices and analysed allowing changes to be
made to the trial conditions and incentives. Tests will be repeated to see how results are altered.
The project will recruit 200 domestic premises to trial a number of DDSR scenarios and meet the
- To understand the scale and structure of payments required to ensure behavioural change.
- To quantify the potential changes in peak load through domestic demand response
- To identify the scope for long term enduring demand response services
- To evaluate which domestic devices offer the greatest potential load reduction / deferment.
- To ascertain customer appetite in relation to deferment of load
The benefits of the scheme will be a report updating the assumptions in the WS3 Transform Model
associated with domestic demand response.
- Recruitment and installation of devices at 200 properties
- Quantification of the amount of peak load reduction possible through such techniques.
- Update WS3 Transform Model parameters
- Deliver the project to time, cost and quality
- Deliver a technology solutions that works out of the box
- To achieve high levels of customer satisfaction
