Abstract:

This document is an Evidence Report for the same trial that produced the New Thames Valley Vision - EMMA Thermal Energy Storage Dataset.

The New Thames Valley Vision (NTVV) project requires, under SDRC 9.4b, the installation of 30 thermal energy storage devices (known as EMMA devices), to include photographic evidence and where required an arranged site visit.

SSEPD confirms that this criterion has been met through the installation of 30 energy storage devices (EMMAs) within domestic properties around Bracknell.

This document provides details of the completion of the installation of 30 EMMAs, and presents the findings identified in line with the evidence criteria specified for the Successful Delivery Reward Criteria (SDRC).

The installation of these devices will help Scottish and Southern Energy Power Distribution (SSEPD) and all other GB DNOs understand the benefits to network operation that these units could bring and also quantify the installation rates, data needs and method of analysis. Under this project, EMMA units are being installed to limit the peak export of Photo Voltaic (PV) Micro Generation on to the low voltage (LV) network whilst allowing customers to consistently store and benefit from the energy their PV systems have produced by using it to heat hot water for normal use in their properties.

The EMMA units configured for this project adjust the amount of PV energy exported onto the network by diverting excess amounts to a conventional hot water storage tank via the customer's existing immersion heater. The EMMA units, adjusted for this project:

Use a learning model of the maximum output from the PV system to calculate a generation profile for the site. The control algorithm takes into account the time of year, the size of the PV system and the time of peak output.

Consider the customer's expected thermal storage needs (hot water tank), which are expected to be between 3kwh to 6kwh per day, subject to PV generation and daily usage.
