 Increased use of electric cars will place huge demand on our network

Smart Street: creating efficient distribution networks

The company is running a number of major technology trials in the North West region all designed to respond to changes in customer’s usage of electricity – such as the use of electric vehicles, heat pumps or solar generation.

Electricity North West believes that to keep bills down for customers it's essential to look at innovative ways of maximising the use of the existing electricity network for which customers have already paid. The key to this is the adoption of advanced energy network technologies such as those being trialled in Smart Street.

In November 2013, Electricity North West, the company who operates the electricity network in the North West of England, was granted funding from Ofgem’s Low Carbon Networks (LCN) Fund for the £11.5 million 'Smart Street' project. Smart Street builds on the learning from the company’s two previous major research and development projects – Capacity to Customers and CLASS.

By combining innovative technology with existing assets, Smart Street aims to make networks and customers’ appliances perform more efficiently and make it easier to adopt low carbon technologies (solar panels, electric vehicles and heat pumps) onto the electricity network.

This innovative approach will keep costs down for customers, reduce carbon emissions and help get the most from the existing network.

 

Background

It is estimated that the cost of upgrading the electricity network to meet future demand could be as much as £1.8 billion by 2025 in the North West alone and £15 billion across Great Britain. That's the equivalent of almost £600 for every household. To minimise potential cost, disruption and carbon emissions, distribution network operators like Electricity North West need to develop smarter and more flexible ways of managing electricity networks.


What will Smart Street deliver?

Smart Street will trial the use of innovative voltage control techniques to optimise the voltage on the network, make customers appliances more efficient and allow more low carbon technologies to be connected without expensive reinforcement work.
New controllable switching devices, called the WEEZAP and LYNX, developed in collaboration with Kelvatek, will be integrated into the network management system. This will be the first demonstration in Great Britain of a fully centralised low voltage network management and automation system.

The project involves a series of trials to test the technology on six major substations and 40 related local substations, serving around 62,000 customers in Wigton, Egremont, Manchester and Wigan. These sites were chosen as they are representative of the company’s geographic area and different customer types.

The new equipment will be installed and the system configured between late 2014 and mid 2015, with live trials due to begin in late 2015. The trials will be carried out on a one-week-on and one-week-off basis until the latter part of 2017.

Understanding whether customers are affected by the trials is crucial to the viability of the solution. The company will use an ‘engaged customer panel’ to help decide the best way to communicate information about the project. A series of focus groups will be held during the trials to collect qualitative information from customers. The aim of the research is to test if customers notice any changes in their electricity supply. A leaflet explaining the project to the 62,000 customers in the trial areas will be sent out in October.


Smart Street partners

Throughout the Smart Street project Electricity North West will work with a number of partners and key suppliers who are leading experts in their fields, either in research, technology or customer engagement. The partners working on the project are Kelvatek, Siemens and Impact Research. Key suppliers include TNEI, the University of Manchester, Queen's University Belfast and the Tyndall Centre.

Smart Street will deliver:

  • Increased network capacity
  • Easier connection of low carbon technologies
  • Reduced reinforcement costs
  • Improved carbon efficiency
  • Reduced overall energy consumption
  • Lower bills for customers
  • Shorter interruptions to customers’ supplies
  • Improved service to customers
  • The project will run from January 2014 until December 2017.
