Electric vehicles and infrastructure

Published Friday, June 28, 2019

This paper explains what electric vehicles are and how successive governments have planned for infrastructure and provided vehicle grants and incentives to encourage and accommodate their growth. It also sets out how the electricity grid is preparing to accommodate any increased demand from EV charging and looks at comparative emissions from EVs and conventional vehicles.

About EVs

Past and current governments have supported measures to encourage uptake of Electric Vehicles (EVs, sometimes referred to as Ultra Low Emission Vehicles or ULEVs) as they can contribute to a wide range of transport policy goals. These include improving air quality and reducing noise pollution. They may also have an important role in the ‘least cost pathway’ to the 2050 net zero greenhouse gas emission target. However, batteries for EVs can require rare elements such as lithium and cobalt, which has raised environmental and ethical issues in countries where these elements are mined. There are also some concerns over ‘peak lithium’ and future shortages constraining growth in the EV market.

Government policy and grants

The Government’s 2018 Road to Zero Strategy outlines how it will support the transition to zero emission road transport and reduce emissions from conventional vehicles during the transition. It sets out several new measures, including an “ambition” for at least 50% — and as many as 70% — of new car sales to be ultra-low emission by 2030, alongside up to 40% of new vans. There have been widespread calls for the Government to accelerate the uptake of EVs and to phase out conventional petrol and diesel engine vehicles earlier.

To achieve the aims in the Strategy, the Government is (amongst other things) providing grants to make electric vehicle ownership more affordable and to offset the costs of installing chargepoints in the home, workplace and on-street. Eligibility and guidance for these grants is available on for vehicle purchases here and for chargepoint infrastructure here.

So, how many EVs are on UK roads?

Despite the rise in the number of licensed ULEV cars on UK roads – 200,000 ULEVs were registered in Q4 2018 - ULEVs only represent 0.5% of the total number of cars licensed.

According to the International Energy Agency’s 2017 EV outlook, these figures place the UK fourth worldwide by market share, and seventh by volume. Going forward, projections by National Grid suggest that the UK stock of EVs could reach between 2.7 and 10.6 million by 2030 and could rise as high as 36 million by 2040.

Where are the EV chargepoints?

Data available from the European Alternative Fuels Observatory shows that the number of EV charge points per 100km of road in the United Kingdom has increased from 42 in 2011 to 570 in 2019. The Committee on Climate Change (CCC) says this figure will need to increase further to match the rising number of EVs on the road. The Government however envisages most charging to take place at home describing it as a “key attraction” of EV ownership. Through the Road to Zero Strategy, the Government has committed £400m to the public-private Charging Infrastructure Investment Fund and says it plans to consult on proposals that would require chargepoint infrastructure for new dwellings in England.

How will increasing numbers of EVs impact the electric grid?

Concerns have been raised that increased EV ownership will create a shortfall in grid capacity, meaning 10 new power stations may need to be built. National Grid responded to these concerns in a myth-buster. It explained that policies and incentives should be able to incentivise charging at non-peak times, therefore resulting in a less significant increase to peak demand.
