Smart Meters

What are smart meters?

The smart meter is a relatively new technology that records real time electricity and gas usage and delivers this information back to the utility companies wirelessly, without the need for manual readings.

Smart meters keep the consumer informed and updated on their actual energy use. By having a smart meter it can give you a lot more control over when you choose to increase or decrease your energy usage. The idea is that smart meters will result in lower levels of energy consumption, which means this will reduce the carbon emissions from each household.

It is fair to say that smart meters have attracted some level of controversy, but some of the concerns we hear about seem to be influenced more by conspiracy theories than by facts. They are governed by strict security regulations and there is no evidence to suggest that they are hazardous to health.

Why have smart meters been introduced?

Smart meters could be good news for householders, because they put a stop to estimated bills and they mean that consumers can sign up for ‘time of use’ tariffs, allowing them to benefit from cheap rates.

UK energy network infrastructure could be put under less strain as a result of time of use tariffs. They pave the way for the National Grid to better manage power supply by reducing peaks in demand. This could have a role to play in avoiding an approaching energy deficit in the UK.

In the UK, the population is increasing and energy demand is high. This is coupled with the decommissioning of many of our existing nuclear and coal power plants, which will decrease the amount of electricity we are producing. Also, renewables such as solar PV and wind produce power intermittently, so we need a grid that is more flexible to meet these supply and demand issues.

Smart meters should allow utility companies to better match demand with supply, by encouraging people to use energy at different points in the day other than traditionally ‘peak’ times; thereby making a more efficient electrical grid.

How do smart meters work?

Smart meters send gas and electricity readings directly to your energy supplier via a purpose-built secure national network (DNN), using radio waves. As well as new gas and electricity monitors, you also get an in-home display. This shows you your energy consumption in the last day, week or month. It also tells you how much you have spent. Smart gas meters are battery-powered and send readings every half hour. Smart electricity meters run off mains electricity and give moment-to-moment readings. The in-home display is also wired into the mains. It costs less than £1 a year to run.

How can I get a smart meter?

They are provided and installed by energy providers, in place of the ones you have now. If you do not already have a smart meter, you will be contacted in the next few years to arrange (free) installation. If you have different suppliers for gas and electricity, the person installing the second meter will link it to the first, and to your in-home display.

Do I have to have a smart meter installed?

The Government has ordered a national rollout of smart meters by 2020. Energy providers are expected to take ‘all reasonable steps’ to install smart meters in every home. However, they cannot force you to have one.

If you decide to opt out, your supplier will probably still swap your meter for a new model, but they can put it into ‘dumb’ mode. This means the meter’s ‘smart’ functionality is turned off so it will not transmit readings automatically and will need to be read in the old way.

There is some speculation that energy companies might not be happy about some people doing things differently, as installing smart meters could cut their admin costs in the long run. They could raise energy prices for those with ‘dumb’ meters as an incentive to cooperate.

If you have any questions about the installation process, or your options, you should contact your energy supplier.

What do smart meters mean for the future?

As we mentioned above, smart meters could mean big savings for bill payers and help the UK to balance energy supply and demand.

If you have a smart meter, you can benefit from cheap rates on time of use tariffs. The lowest of these at the moment is 4p per hour, so if you can get used to using your energy at off-peak times, you could potentially save a lot of money.

As the energy mix becomes more complex in terms of supply and demand continues to grow, smart meters will become a powerful tool to allow utility companies to continue to supply customers with uninterrupted electricity supply as and when it is needed.
