The Electricity Storage Network, managed by Regen, is an industry group and voice for grid-scale electricity storage in GB.

It includes a broad range of electricity storage technologies and members, such as electricity storage manufacturers and suppliers, project developers, optimisers, users, electricity network operators, consultants, academic institutions, and research organisations.

The Electricity Storage Network’s five key priorities

 

 

1. Creating a fair policy and regulatory framework for storage to enable a high renewables system.

2. Electricity markets, investment, and business models for storage.

3. Supporting emerging storage technology (and supporting technology) sectors, including removing barriers to the development of long duration storage.

4. Delivering the future energy infrastructure and network investment.

5. Building a mature and responsible industry and supply chain.

The ESN is committed to creating an environment in which storage can flourish, ensuring that regulations and markets work for all types of storage, without favouring one particular technology.


We want to ensure our membership is a dynamic force that can spark change at the cutting edge of the energy system.

Get in touch to find out more about the innovation projects, thought leadership reports and policy work that we are planning and let Olly Frankland know which of the areas you’d like to be involved in.

Ofgem have proposed to adopt the ESN’s definition of storage in the electricity generation licence:

“Electricity storage 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”

As a result of the ESN’s positive and influential relationships with decision makers over a number of years, we have succeeded in achieving a comprehensive, technology neutral and future-proof definition for storage.

ESN working groups

As a network, we hold regular working group meetings where we discuss sector developments and how industry and government can improve and adapt to increase the uptake of storage. We work closely with government and regulators to create a sector that allows storage to flourish.

See our events page for a list of upcoming sessions.


Icons 160 160 Financial Modelling 1Markets and Revenues Working Group

The markets and revenues working group looks at key market opportunities and new business models for storage, including future plans from the system operator and distribution system operators, existing and emerging markets and network charging reforms.


ElectricitySustainability, Safety and Supply Chain Working Group

This working group is a space to discuss many important aspects of the investment, development and operation of storage sites in the UK. The focus is on creating a sustainable industry that can aid the transition to net zero, with the  core principle of adhering to environmental, social and corporate governance (ESG) criteria.


LightbulbInnovation and Technology Working Group

The focus of this working group is to understand the role of new, emerging and enabling storage technologies. The group is seeking to highlight the roles new technologies can provide to the electricity system, removing barriers to new technology development and to enable the ESN and its members to engage with research and innovation.


Grid ConnectionsGrid Connections Working Group

The remit of the Grid Connections Working Group is to address key issues related to accessing the electricity network, in the context of reducing barriers preventing renewable generation and low carbon technologies from connecting at the speed and scale needed to meet net zero.


ESO ESN Strategic Logo 5ESO Strategic Liaison Meeting

The ESN/ESO strategic liaison meeting is our regular meeting with the ESO to discuss how storage can best participate in markets. Topics include dispatch rates in the control room and the ESO’s forward plan for their markets.


Planning IconPlanning Working Group

This working group provides an opportunity for members to discuss issues faced in the planning process and how we can influence planning reform, in the context of a planning system that members have identified as not fit for purpose, creating delays that impact the deployment of storage projects.

Policy priority areas

We have ambitious plans for the coming year, our areas of focus will include:

Creating a fair regulatory framework for low carbon generation and technologies: A regulatory and market framework that has net zero at its core. Ofgem and the network operators must have clearly defined statutory remits to prioritise decarbonisation.

Electricity markets for a net zero electricity system: Markets that function effectively in a net zero system, incentivising the right kind of assets in the right places. This should include recognising the full value of low carbon assets, transparent reporting on carbon intensity of all markets, and ensuring markets are fully accessible.

Sustainability and ethics of the mineral supply chain: Increased awareness and a position in the industry on the concerns with the mineral supply chain. This could include further research and working towards a standard for the industry.

Creating a legal framework for storage: Including storage formally in the electricity licence framework. This would include a constructive industry debate on options available, including defining storage as a subset of generation or creating a new licence.

Local energy planning and investment: We need a new model for local governance of energy which allows local bodies to plan for and invest in energy policies which can deliver their ambitious climate goals.
