The UK’s first large-scale lithium-ion battery has been connected to the electrical grid on the island of Orkney – in the Scottish Isles in the UK – as part of a trial by Scottish Hydro Electric Power Distribution (SHEPD).

The installation of the 2MW battery at Kirkwall Power Station on the island is to store excess energy produced from renewable sources. The island group has more producing ability than capacity for storage in the grid, resulting in wasted energy.

Mark Rough, Head of commercial activity for SHEPD said the installation will not provide an immediate solution to the current constraints of the Orkney distribution network, however he hopes the study will show batteries to be a cost-effective way of freeing up capacity on the network to help facilitate new connections of low carbon generation.

The battery, made by Mitsubishi, has been part of a two-year test in Nagasaki, Japan. The Low Carbon Networks Fund is funding the project. 

Younicos and Samsung collaborate for multi-MW battery parks

Renewable energy systems specialists Younicos, and Samsung SDI have announced a strategic partnership to build megawatt scale grid-tied battery parks. Younicos has specialist control strategies that will be combined with Samsung’s expertise in lithium-ion cells in the fully-automated battery parks.

These parks will play a crucial role in enabling the use of up to 100% wind and solar energy in existing grids and making renewable energy sources competitive. The battery parks will offer frequency regulation, voltage control, black starts, and short circuit power and have a construction time of 12 months.

Samsung has guaranteed the performance of the cells for 20 years.??

German-based Younicos has been trialing its first MW-scale battery system since December 2012, with success to prove the technical and commercial viability. Younicos focuses heavily upon using batteries as a means to store energy from renewable sources. It will partner with Samsung SDI for system integration and lithium-based systems in European markets including Germany, Austria and Switzerland. 

Clemens Triebel, Founder and speaker of the board of Younicos explained the pairing with Samsung: “We’ve tested all industrially available lithium cells since 2007. Samsung provides the commercially most suitable cell technology for balancing short-term fluctuations in the grid. With Samsung’s unique 20-year guarantee, we are setting a new benchmark in this emerging market. Our battery parks will provide crucial grid stability functions much faster, more efficiently and cheaply than conventional fossil plants, allowing us to switch off coal and other thermal power plants when sufficient wind and solar power is available. Even though current market design does not yet reward these advantages, our battery parks can already compete in markets for frequency regulation and also provide additional system services.”??

The partnership will be extended to use Samsung’s lithium battery technology for Younicos’s current energy storage hybrid battery systems for off-grid renewable energy storage.
