Business need

The UK government are mandating energy companies to offer smart meters to all 26 million homes across the UK by 2020. For npower, the challenge is to have the capacity to potentially install smart meters in more than one million homes a year, nearly 19,000 each week. These meters must be secure, easy to deploy and super-reliable.


Providing secure connectivity through a Vodafone Global SIM allows npower to install a smart meter anywhere in Britain. The smart meter can send a monthly or daily reading and 48 half-hourly profile readings where consent is given. All updates, along with a map of the daily usage, can be seen via the customers’ In Home Display.
