Adapting to the new reality

Ofgem’s justification of the move to block DNOs from owning and operating storage was that it sees network operators increasingly in the role of buyers of flexibility services, and as such, does not want them to operate their own storage. It believes that as DNOs transition to becoming distribution system operators (DSOs), their impartiality must be guaranteed, and that this will not be possible if they have an interest in a particular option.

Accelerating innovation

Substation monitoring has been an area of interest amongst distribution network operators (DNOs) for some time, as the way consumers use and interact with the network changes due to the relatively rapid growth of photovoltaic installations, electric vehicles, domestic-level battery storage and so on. Before these relatively new technologies were widely adopted, it was sufficient to manually record a reading from an analogue maximum demand indicator during a physical inspection once or twice a year, but this is no longer considered sufficient by many in the industry who are now interested in annual and diurnal patterns, harmonics and more.

A platform-based approach to distribution operations

The energy landscape today is undergoing significant transformation as distribution network operators (DNOs) continue making the transition towards distribution system operators (DSOs). Led by widespread growth of distributed generation – including 27.0GW of installed rooftop solar capacity globally in 2017(1) – along with battery storage, electric vehicles (EVs), and other forms of distributed energy resources (DERs), DSOs face significant changes to the traditional energy delivery model. Coupled with an evolving regulatory framework, in order to continue to provide safe, reliable, and affordable grid services, DSOs are looking at new, modern approaches to safely connect, model, manage and optimise customer DERs within the overall network.

A whole new world

Whether you agree with its conclusions or not, the Cost of Energy Review lays out a clear, and at times sobering, review of the development of the electricity sector over the last 50 years and its present complicated structure. For those of us who have been arguing that we need radical change it certainly offers that. It covers all aspects of electricity supply but I’m going to look at the proposals for networks which are probably more far reaching than for other areas, even if they have received less attention.
