Guide for the Geo smart meter display 

Helpful information

Your electricity usage is measured by your electricity meter, and appears on your electricity bill in kilowatt hour (kWh) units. The appliances in your home use various amounts of energy. A typical kettle will be rated at about 2kW which means while in use it consumes 2kW of power per hour. If the kettle were to be used for a total time of one hour it would consume 2kWh or 2 units of electricity. Through switching the individual appliances on and off, your smart meter display will allow you to start to see how much individual appliances use as well as the cost of running them. 

Useful tip

Why not start by turning off all appliances you can do without for a few minutes. This would include lights, TVs and digi boxes but not fridges or boilers. Then check your smart meter display to see how many kilowatts you’re using. This figure is your ‘base load’. Knowing your base load can help you see how much energy your appliances use; simply deduct it from the total number of kilowatts displayed. Overtime, you should gain a better understanding of your day-to-day energy use and can look for ways to reduce this by using energy more consciously.

You may use this information to help you identify what energy saving behaviours have been effective and also what events resulted in higher energy use over the different periods of time displayed.

The electricity screens will show any savings achieved by turning lights off when not needed, or taking appliances off standby. You may find the longer time periods shown on these screens particularly useful if you have taken energy-saving steps such as a change to energy saving light bulbs. In the same way, the information displayed on the gas screens should prove particularly useful for optimising the way your gas central heating is set to operate as it will reflect any savings made by turning room thermostats down by even a very small amount.

Carbon dioxide (CO2) emissions – your carbon footprint

The smart meter display shows the tree logo whenever the information on view represents CO2 emissions that may be attributed to your household’s energy usage. This information is accessed by pressing the tree button. You can switch between gas, (if applicable) electricity and total CO2 emissions for both gas and electricity by pressing the select button.
