Maximising interoperability for first generation (SMETS1) smart meters
We're seeking views on proposals to require energy suppliers to maintain smart services when consumers with SMETS1 smart meters switch energy supplier.
A number of energy suppliers are installing SMETS1 smart meters, using their own data and communications systems to provide smart services. While SMETS1 meters support accurate bills and near real-time energy consumption which enable consumers to realise the benefit of smart metering, consumers may lose smart services on switching to another energy supplier.
The government’s long-standing policy for resolving this issue is for all significant populations of SMETS1 meters to eventually be operated via the national data and communications provider, the Data Communications Company (DCC). However, as energy suppliers are not required to make use of a DCC SMETS1 service there is a risk that the benefits to consumers of an interoperable SMETS1 service are not delivered in a timely manner.
In recognition of this, we are consulting on proposals to require energy suppliers to enrol SMETS1 meters in the DCC, or failing that to replace them with SMETS2 meters, within a specified timeframe. In addition, a proposed new back-stop obligation would require energy suppliers to replace any SMETS1 meter that is not enrolled with a SMETS2 meter by the end of 2020.
