The vast majority of battery projects set to compete in Britain’s upcoming Capacity Market (CM) auctions will face significantly decreased de-rating factors after it emerged that most projects are still set to use either 30 minute or one hour duration batteries.

Energy storage provider Connected Energy has secured £3 million (US$4.13 million) of investment from Macquarie Group and ENGIE to fuel its growth plans in the UK and abroad.

AES Energy Storage and Siemens, which between them have delivered 500MW of energy storage worldwide already, will target 160 different countries and build a 400MWh battery system in California through new joint venture Fluence.

Fresh details have emerged surrounding UK-headquartered utility Centrica’s rumoured 100MW battery after a planning application was submitted to Kilkenny County Council in Ireland through a joint venture formed in part by local subsidiary Bord Gáis Energy.

VLC Energy has become the latest firm to finish its Enhanced Frequency Response (EFR) battery projects following the completion of two projects totalling 50MW.

A “hybrid power plant”, controlling the grid for an entire island and its inhabitants, has been created with the addition of a management and control platform from energy storage system integrator Greensmith.

Developer INRG Solar is plotting a 120MW solar array near Scunthorpe, northern England, in what could be the country’s second proposed solar farm of “significant infrastructure” status.

Well, we seem to say it at the end of every year, but 2017 seemed a lot busier than 2016, 2016 was busier and more exciting than the year before that, and so on! There have been some hints already on what the industry and its observers expect to see in 2018 and we do not doubt energy storage will continue in its rise to become a flexible cornerstone of the world’s electricity infrastructure. In the meantime, let’s reflect on the top news stories of last year, as reported by Energy-Storage.News and based on readership statistics from you:

While acknowledging that the economics “vary significantly” by region and application, Navigant Research has forecast that energy storage for integration of renewables and co-located with solar or wind could be worth more than US$20 billion by 2026.

With the release of the most recent Capacity Market pre-qualification register, the UK’s utility-scale battery storage pipeline has now reached nearly 8GW. Solar Media market research analyst Lauren Cook takes a deep dive into the projects that made it through pre-qualification, and what these results mean for the projects likely to get built in 2018.
