- £4m battery facility launches today at Willenhall substation near Wolverhampton, UK.
- The facility will be the fastest and one of the largest battery energy storage systems in the UK.
- E.ON and Uniper will use battery for testing storage technology
One of the UK’s largest battery-based energy storage facilities has been connected to the grid as part of new research led by the University of Sheffield on the growing area of energy storage.
The £4m facility was officially launched today (Thursday 17 March 2016) with the announcement of a new innovation project with energy companies E.ON and Uniper looking at future possibilities for large-scale energy storage and how to overcome the challenges associated with connecting such technologies to the grid.
The facility is one of three of the largest batteries currently operational in the UK – and the first to use an innovative lithium titanate battery, supplied by Toshiba. One of the facility’s unique capabilities is how quickly it can respond to demands from National Grid to import or export electricity at short notice – at 4/10ths of a second, it is the fastest of any battery energy storage system in the UK.
The lithium titanate battery was chosen because it is fast to charge and discharge, has a long lifetime and is arguably safer than alternatives such as lithium ion.
The UK Government’s Department of Energy and Climate Change has identified energy storage as a key priority and is expected to launch a new policy later this year. Many countries will need energy storage technologies to balance the sometimes unpredictable supply of renewable energy and demand.
A recent report by the National Infrastructure Commission has suggested that energy storage could contribute to innovations that could save consumers £8 billion a year by 2030 as well as securing the UK’s energy supply for generations.
Based at the Willenhall substation near Wolverhampton in the West Midlands, part of the Western Power Distribution Network, the facility is owned and operated by the energy storage research team at the University of Sheffield as part of the Energy2050 initiative, in conjunction with partners at Aston University and the University of Southampton.
Professor David Stone, Director of the Willenhall Facility and the Centre for Electrical Energy Storage at the University of Sheffield said: “As the demand for energy increases in the UK, storage systems are needed to balance supply. The first commercial projects are coming on line, but there are still many technical issues to be explored in order to maximise the potential of these technologies and to reduce costs.
“This dedicated national research facility has been designed to offer enhanced frequency response to peaks in demand and is available to be used by other academic and industrial projects for their research and to test new technologies.
“I am also delighted to announce a new innovation project with E.ON and Uniper, in which we will be using the facility to help develop their understanding of operating a lithium titanate battery”.
Arne Hauner, Head of Innovation Economics from Uniper said: “E.ON and Uniper will use the Willenhall battery system to provide ancillary services to the electricity network. The reason for doing this is to test the operation of a battery in a new market and to gain operational experience of a different battery storage technology compared to those which we currently operate.”
The University of Sheffield team, with their partners from Aston and Southampton, are already planning the next stage of research including looking at how used electric vehicle battery packs could test the viability for domestic or industrial electricity storage. This ‘second life’ system is due to go online later this year, aiming to combine the energy from the battery packs so that it functions together as a single larger battery unit.
The Willenhall battery had its official launch today, Thursday 17 March, with over 70 stakeholders from government and industry attending, including representatives from the Department of Energy and Climate Change, National Grid, Distribution Network Operators, and electricity suppliers.
The research is being funded by the Engineering and Physical Sciences Research Council (EPSRC) and involves both industrial and academic partners: the University of Sheffield, Aston University and the University of Southampton, Toshiba, grid operators Western Power Distribution, and power and automation technology company ABB.
Feasibility studies for this project were funded by both the Innovate UK and Department of Energy and Climate Change(DECC) and additional partner organisations include Portastor, Sterling Power Utilities, Converter Technologies, G&P batteries, Energy Cost Advisors Ltd, Renault and TMETC.
