3. Customer-led changes to energy use
Driven by decentralisation and decarbonisation
Customers with more flexible distributed assets – generation and electrification of transport and heat
New markets for customers to access

4. Driving electric: challenges & opportunities
Electric vehicles (EVs) offer an opportunity to sequester renewable generation and reduce air pollution in cities, however..
..electrifying heat and transport to meet the 2050 decarbonisation target could change the current peak demand on the networks:
An EV electricity demand is of the same order of magnitude as an average UK household
A huge uncertainty exists in EV and charging point growth projections
If charged at a time of relatively low demand (e.g. overnight), the impact may be minimal
We are in process of gradually introducing EVs into our fleet, installing EV charging infrastructure on our sites, and running a number of trials of bi-directional charging.

5. What we are doing now Improving our forecasting capability.
Rolling out low voltage monitoring at substations.
Facilitating smart metering rollout.
Platform for future network flexibility solutions - £83m smart grid enablers programme.
Updating our design policies as new information arises.
National level activity:
Electricity Networks Association (ENA) Open Networks project;
ENA Low Carbon Technology group – notification processes, knowledge sharing;
Ofgem’s Network charging reform.
Innovation projects to explore the opportunities of EVs

6. Vehicle-to-grid (V2G)
Bi-directional charging could enabled by vehicle-to-grid technology – a game-changer?
Battery on wheels: an EV becomes a dispatchable, mobile source of electricity
Potential for customers to use the batteries in their vehicles as a means to:
Balance their domestic or commercial load
Supply partially connected (reduced capacity post fault) systems or microgrids
Earn revenue from exporting electricity back to the grid.
We have started early trials to explore the customer use, technical standards and barriers to the adoption of V2G technology.
