Norton Rose Fulbright E-Storage Matters

Since the publication of our first E-Storage Updater we have seen a multitude of interesting e-storage developments. New alliances aimed at the promotion of grid-scale storage have been formed, for example between ENGIE and SUSI Partners AG. We expect that the acquisition by the French oil and gas company Total S.A. of Saft Group, a leading designer and manufacturer of advanced technology batteries, marks the start of increased M&A activity of e-storage technology development companies.

Meanwhile, around the world, the contours of new regulatory frameworks are emerging which we expect to enhance the business case and drive down costs of e-storage technologies. Even in jurisdictions that do not (yet) have the proper regulatory framework or market design in place to boost energy storage developments, we note increased activity by early adopters to gain familiarity with various technologies at different levels in the energy system, mainly in anticipation of ‘the next big thing’ in the energy landscape.

At an energy storage event hosted by our Amsterdam office we saw great interest in e-storage from a variety of players active in the energy sector, ranging from technology developers to utilities and financiers. From the knowhow and experience of e-storage projects gained through our international energy practice, we have compiled some of the global trends, key (legal) considerations and opportunities for e-storage in an article located below in our In Focus section that was first published by Project Finance International and is available on our website here. 

We hope the article and the second edition of our E-Storage Updater are of interest to you too, and look forward to receiving any comments, suggestions or queries you may have.

Policy and regulatory news


GTM released a report in January 2016 predicting that energy storage costs are expected to decrease by 41% by 2020 as key components get cheaper and the balance-of-system costs, including hardware, labour and customer acquisition fall below US$400 p/kW from a current average of US$670 p/kW.

The International Energy Agency (IEA) have released their first publication that focuses on the electricity market framework for low-carbon power systems. The publication discusses the relevant dimensions of electricity market design, the balance that policy makers must strike between supporting innovation and competition while mobilising capital for the deployment of low carbon sources.

Storage has been titled as being the 'game-changer' which has the potential to contribute to solving the challenge of wind and solar electricyit generation. The World Energy Council has published a report which analyses what the cost base of an array of storage technologies actually means, considering the importance of defining the business model and how the storage plant is being operated. The report further identifies a number of insights on the value of storage from which certain recommendations can be made by policymakers including:

  • "focusing less on an investment cost only approach for storage technology assessment;
  • examining storage through holistic case studies within a specific context;
  • accelerating the development of flexible markets, working with transmission and distribution system operators and regulators to help quantify and realise the true potential value of increasing system flexibility;
  • establish policy support and an enabling regulatory framework to facilitate further commercial deployment of storage technologies; and
  • consider storage as a key component when planning for grid expansion of extension."

The Renewable Energy Association have predicted 2016 as a 'breakthrough year' for energy storage; a technology not only seen as vital to the large-scale rollout of renewable energy, but also offering the prospect of lowering customer's energy bills across the UK. KPMG have released a report which assesses the trends relating to the development of decentralised energy and storage, the key benefits and the barriers to its introduction.  

The UK government announced in the Budget 2016 that it will allocate at least £50 million for innovation in energy storage, demand-side response and other smart technologies over the next five years to help new technologies and business models access the market. Ofgem also will consult later this year on the future of the £100 million Network Innovation Competition to maximise the delivery of genuinely innovative projects and technologies.  

In March 2016, Carbon Trust and Imperial College London published a report on the significant changes the United Kingdom's electricity system is undergoing to provide electricity that is secure, affordable and ultimately low carbon. The report focuses on energy storage, distinguishing the different types of storage and the services a storage solution can provide, alongside other flexible options such as demand response and interconnectors as a way of providing the flexibility required by a future system that is likely to see an increasing share of intermittent renewables and more distruibution generation.  

According to a newly released report from the eStorage Project, development ready sites for new pumped hydro energy storage plants  will offer generation potential of 2,291 GWh. These sites are in the EU-15, Norway and Switzerland.

On 4 May 2016 the EU Member States gave a favourable opinion on the Draft Regulation establishing a guideline on electricity transmission system operation – the System Operation Guideline. Part of the SO Guideline includes the Load-Frequency Control and Reserves Network Code which will help ensure coherent and coordinated operation of transmission networks to achieve a satisfactory level of frequency quality. It will do this by focusing on frequency quality criteria, frequency control structure, frequency containment reserves, frequency restoration reserves, replacement reserves, exchange of reserves and synchronous time control and as such is of importance for all storage systems who want to participate in the reserve control market.

The National Infrastructure Commission (NIC) has called for a raft of regulatory changes to create a level playing field that would allow energy storage and demand flexibility to ensure security in the UK's future low-carbon energy system. The NIC published a report on the challenges facing the energy sector in the UK and focused on the benefits that can be achieved through building more flexible electricity systems and steps that will enable the country to get there. The Commission believes a future UK system principally built on interconnection, [energy] storage and demand flexibility could save businesses and domestic consumers as much as £8 billion a year by 2030 whilst helping the UK meet its 2050 carbon targets and achieving security of supply.

Trade groups representing Europe's solar power, heat pump and battery energy storage sectors have come together to call for new policies designed to promote the combination of solar and storage technologies.
