Bringing Energy System thinking out of the Dark Ages

To make the majority of our energy clean, we need more than just clean energy generation — the other elements of the energy system must change too. A multi-phase transformation of the energy system will enable renewables to dominate the generation mix in the future.

Centralised vs decentralised

It is important to point out that neither a centralised or decentralised system is necessarily better. Each system better supports certain operational and economic principles, in combination with energy type and location attributes. For example, the general view is that a more decentralised system will better suit a high renewables penetration in the UK. However, massive scale solar renewable energy in deserts, as promoted by the DESERTEC Foundation, will better suit nationally centralised and highly interconnected systems. The DESERTEC idea, however, faces significant feasibility challenges due to the political and security instability of many of the regions where the generation would take place.

Transformation to a clean energy system

The changing role of the consumer is of primary importance on a domestic (new service propositions and smart appliances) and industrial/commercial level (new manufacturing processes and operational arrangements). The model is particularly appealing since the responsibilities and benefits of the energy system can be more evenly shared.

The devolution of responsibilities is likely to result in a conceptually more complex system, thereby requiring various components to work together in concert, much like an orchestra. Somewhat counter-intuitively, however, such a system is in fact more resilient and stable due to its greater diversity. Of course, a conductor is required to ensure harmony. This need not be a single entity, as is currently the case for the UK’s centralised system, and the role can be created by a framework that defines roles and responsibilities (to be covered in a later discussion).

Such a system would require far more information around coordination and augmentation in the capabilities of certain parties. For example, frequency response actions to voltage issues would be devolved to a larger number of distributed devices that can collectively address fluctuations. Related concerns around the impacts on system inertia, for instance from non-synchronous components such as the power electronics for solar PV, can similarly be solved through the same devolution principles. More specifically system inertia (and other system services) can be added by storage or certain types of distributed generation assets.

Re-energising the UK’s clean energy sector

Furthermore, the change will act as a manifesto for the ESC which will hopefully re-energise the UK’s clean energy sector.
