Policy and Issues


ESN responds to BEIS and Ofgem's Call for Evidence on 'A Smart and Flexible Energy System'. 

The ESN response can be found here, and you will see that our key request is to press on, with a sense of urgency, with removing the range of regulatory and commercial barriers currently faced by storage providers.

Regulating Electricity Storage

The UK is behind many other countries in its adoption of modern electricity storage. We are involved in responding to a consultation by BEIS and Ofgem to promote 'A Smart, Flexible Energy System'. Our intention is to promote electricity storage whilst highlighting the existing regulatory barriers to its implementation in the UK.

Questions that need answering are:

  1. Should electricity storage be classed as generation or storage?
  2. Does electricity storage need to licensed?
  3. How should electricity storage be defined?

In addition to activities in the UK we are working in Europe, through the European Association for the Storage of Energy, and the Commission are busily assessing their approach to storage.

If you have any comments on these proposals please contact us:

Electricity Storage in the National Interest

We propose that the UK power system should have a minimum of 2,000 MW of new network connected electricity storage by the year 2020. This represents just less than 10% of the predicted increase in renewable generation capacity over the same time period.

You can download our proposals in "Development of Electricity Storage in the National Interest".

We will press government to include support for new storage in the electricity market reform process - whether as targeted actions within the capacity market or contracts for differences, or in a specific targeted action.

 


Our definition for Electricity Storage

The Electricity Storage Network has an agreed definition for electricity storage:

Electricity Storage” in the electricity system is the conversion of electrical energy into a form of energy which can be stored, the storing of that energy, and the subsequent reconversion of that energy back into electrical energy.

Electricity Storage Facility” in the electricity system means a facility where Electricity Storage occurs.

Principles:

Any definition should not include terms that refer to other asset classes or licensed activities, such as supply or generation (or demand).

The definition in the DECC Consultation: Consultation on amending the CfD contract and regulations (page 21, section 47) is not appropriate as it also includes "generating unit".

This definition is published in the BEIS / OFGEM call for evidence (November 2016) on page 34, paragraph 32.


Investing in Electricity Storage

Use Cases

The Electricity Storage Network has been working with Innovate UK to develop a series of Use Cases to help potential investors and those new to electricity storage understand the opportunities.  We are asking our members and other stakeholders to help complete these use cases with meaningful costs and benefits.

Our first template Use Case is for behind the meter domestic scale storage:

1a: Domestic Behind-the-Meter Storage

This use case can be downloaded above and used for the initial five use cases:

  1. Behind the meter domestic
  2. Industrial and commercial customer owned
  3. Merchant model bulk storage
  4. Storage used principally to defer low voltage network upgrade
  5. Storage used to directly support intermittent generation at medium voltage

If you want to be involved please get in touch.

For more information see this article.


First Use Case Available

The first use case has been produced by TNEI and covers the use of storage when co-located with intermittent renewable generation. The use case details potential income now and in the future, and any barriers or hurdles that need to be resolved to access that income.
