2016 was the year when energy storage came of age globally. Cost reductions, particularly in lithium-ion batteries, together with an emerging ambition by governments and regulators to design flexible, resilient future electricity systems, drove storage towards the mainstream. The year was also characterised by new partnerships, mergers and acquisitions as utilities, oil majors and the automotive industry developed their storage strategy. Our global Energy team reflects on some of the highlights:
 |
Simon Currie, Global Head of Energy (Sydney, Australia): In 2016 we closed the first hybrid grid-connected solar/storage project - the Lakeland project in the far north of Queensland, Australia. The Pacific region is likely to be one of the markets which is an early adopter of storage technology due to the combination of thousands of islands and low population density - especially in Australia. There are already dozens of microgrids across Australia. At this stage it is all about sharing the learnings from each project with our global teams and other stakeholders. |

Jeremy Hushon, Partner (Washington DC, USA): Energy storage will be key to helping the nations of Latin America achieve higher penetrations of renewable energy. For Costa Rica, with rich hydro resources capable of delivering 100% of the country’s power needs during certain seasons, storage could offer an opportunity for the country to achieve secure year-round reliance on renewables. Already, businesses are pursuing the benefits of commercial storage solutions. Demand Energy recently announced the commissioning of a battery storage and solar PV installation to be attached to a medical manufacturing plant in Costa Rica which will allow the plant to undertake power-sensitive manufacturing without systemic outage risk. |
 |
Rob Marsh, Partner (London, UK): In the UK, we saw grid-scale storage emerge as a big winner in both the Enhanced Frequency Response and Capacity Market auctions, as well as the first co-located storage projects being developed alongside existing solar PV schemes. The UK government, in its proposals for an Industrial Strategy, is considering how to become a global leader in battery technology. In 2017, we expect to see proposals for the removal of regulatory barriers to storage once the conclusions of the UK government’s call for evidence on a Smart, Flexible Energy System are published in the Spring. It promises to be an exciting year. |
 |
Matthijs van Leeuwen, Of Counsel (Amsterdam, the Netherlands): Last year we saw a significant focus on new energy technologies that enable an accelerated integration of renewable energy sources. For the EU, this resulted in the proposed Winter Package, a comprehensive legislative package that should facilitate energy storage for households and at grid-scale. New energy storage related business models, contract structures and cross-sector initiatives in the EU that are currently being piloted should benefit from the reforms. 2017 will be a fascinating year and we look forward to further shaping ‘enabling’ regulation through our EU-wide participation in regulatory reform and pilot projects. |

Energy storage trends and opportunities in emerging markets
The International Finance Corporation (IFC) and the Energy Sector Management Assistance Program have published a report which provides an overview of energy storage developments in emerging markets. The report discusses the services that energy storage systems (ESSs) can provide, as well as the key trends and barriers in emerging markets. Although most activity in the energy storage market has centred on developed economies with favourable regulatory frameworks, energy storage deployments in emerging markets are expected to grow over 40% annually in the coming decade. The report concludes that perhaps the most important factor in a successful energy storage market is the availability of low-cost financing. To unlock low-cost financing, the report finds that it is important to utilize technology from reputable and established vendors that can offer warranties and performance guarantees on their products, to rely on experienced and capable system integrators and for industry participants to educate relevant stakeholders on the benefits of energy storage. These factors can reduce the perceived investment risk, and greatly increase interest and trust in energy storage as a beneficial technology for emerging markets, reducing the cost to finance and develop such projects.
New “Hydrogen Council” launches in Davos
13 global industry leaders join together in promoting hydrogen to help meet climate goals and calling on governments to support the hydrogen ecosystem. Members of the ‘Hydrogen Council’ confirmed their ambition to accelerate their significant investment in the development and commercialization of the hydrogen and fuel cell sectors. These investments currently amount to an estimated total value of €1.4 billion per year. This acceleration will be possible if the key stakeholders increase their backing of hydrogen as part of the future energy mix with appropriate policies and supporting schemes.

The project will eliminate fossil fuel based generation on three outer islands and reduce it by more than a third on a fourth island.
EU Winter Package: energy for all Europeans
For the first time, energy storage is proposed to be taken into account in the updated EU regulatory package. The draft electricity directive includes a definition of energy storage, which may support the emergence of a new asset class and encourages system operators to integrate storage into the European energy landscape in a non-discriminatory fashion. The proposals will need to be accepted or amended by national governments before they can proceed towards implementation.
EASE and EERA Energy Storage Roadmap
The European Association for Storage of Energy (EASE) and the Joint Programme on Energy Storage under the European Energy Research Alliance (EERA) have collaborated to draft an updated Energy Storage Technology Development Roadmap.

Germany removes regulatory barrier to storage (email here for details)
E-storage systems in Germany were previously faced with regulatory uncertainty in respect of the taxes and charges which might be applied to either electricity imports into the storage system, exports from the storage system or even double-charged on both charge and discharge. The revised German Renewables Act (EEG) which became effective in January 2017 has now brought a substantial improvement regarding the regulation of e-storage systems. New section 61k EEG ensures that electricity which is temporarily stored in a physical or mechanical storage system will not be subject to the EEG surcharge, provided that the electricity is charged with the EEG surcharge when it is exported onto the public grid. Even if the electricity is used for self-consumption, there is relief of the EEG-surcharge to the extent the self-consumption does not exceed 500 kWh. This regulatory change now supports several business models for storage systems which are based on a multi-use approach such as the combination of reserve control electricity and self-consumption.
A silver bullet? Inside FERC's landmark energy storage rulemaking
To open wholesale markets to energy storage, the Federal Energy Regulatory Commission (FERC) is proposing to amend its regulations “to remove barriers to the participation of electric storage resources and distributed energy resource aggregations in the capacity, energy, and ancillary service markets”.
What energy storage policy could look like under President Trump
It is unclear what Trump thinks about energy storage. Even under Obama, noting his efforts to expand clean energy and reduce greenhouse gas emissions, federal energy storage policy had not crystallised. It is expected that the cities and states that have largely driven the expansion of distributed energy resources through strong policy and regulatory action will continue to do so. However, the industry would be remiss if it did not seek greater representation in the policy agenda of an incoming administration.
