A case study in a 2016 review
This is a case study in a review. The publication page gives 19 Jan 2016. It describes possible uses. It does not describe a system that was running in Britain, and it does not say a regulator had adopted one.
The report is by the UK Government Chief Scientific Adviser. The case study is credited to Igor Nai Fovino and Jean-Pierre Nordvik, of the Joint Research Centre of the European Commission. That centre was investigating practical uses of distributed ledgers in the retail energy market. It gives two.
The first is people producing energy at home or in a local community, and trading it. Combined with smart meters and batteries, a distributed ledger could open that market to people who both produce and use energy. Smart meters could record the energy they generate on a distributed ledger. The case study calls that the equivalent of an energy-coin system. Electricity produced that way could be used in the house, stored in a battery, or given back to the grid. Because of the ledger, it could also be used somewhere else, for example when charging an electric vehicle abroad, or sold through the ledger.
The second is a ledger of energy contracts. A person who wants to change supplier has to close one contract, open another, and revisit the contracts for related services. Recording those contracts on distributed ledgers would make the change simpler, including on a computer or a phone. Questions remained about whether these uses can grow, stay secure, and stay stable.

Technical detail
The case study calls the first use micro-generation, and the second an energy contracts ledger. Its last sentence says the benefits merit further investigation. That is the authors' view of the idea. The sale through the ledger is compared to a stock exchange. A column of text beside the case study, on the same pages of the file, is about digital identity and organisational registers. It was not used. The report's sentences about land registries are on the public records page. “Scalability, security and stability” is the case study's list.
