Smart metering will play a key role in the creation of a new smart grid that will enable the energy system to better predict what electricity is needed, and when and where it is needed. Data from smart meters allow for power systems’ operations to be planned in accordance with accurate evaluation on demand, and maintaining carbon-heavy extra capacity may no longer be required. Data, and its analysis, will change the way we think about energy and we can all play a part in creating a cleaner, greener, lower carbon network. Smart metering will be the cornerstone of our smart grid and drive the uptake of low carbon technologies.
