The largest energy storage system in the Nordic countries, supplied by Landis+Gyr and Toshiba, has arrived in the Suvilahti area of Helsinki. The battery system weighs about 28 tons and includes over 13 000 lithium-ion SCiB™ battery cells. It was installed in mid-May, in readiness for implementation in early June.
The battery energy storage system was transported through Europe, passing through cities like Verona, Munich and Lübeck to Travemünde, from where it was shipped to Helsinki. Once the battery container had been hoisted from a truck onto its foundations, mechanics from Toshiba’s European Center of Excellence, part of the Toshiba Group for Storage and Smart Grid systems, prepared the technology for use. Now the battery is ready for the next phase: it will be connected to a transformer, together with the solar panel located in Suvilahti. In early June the solution will be connected to the electricity network in the Suvilahti area. Landis+Gyr and Toshiba are heavily involved in the installation and implementation work, and are also responsible for user, service and maintenance training.
The output of the BESS is 1.2 MW and the energy capacity is 677kWh. As well as the battery system, the scope of the Landis+Gyr and Toshiba delivery also includes a master control system, two power inverters, a transformer and a service and maintenance contract covering four years. Helen Electricity Network and the Finnish grid operator, Fingrid, will exploit the technology in a pilot project to investigate the new opportunities provided by megawatt-scale energy storage systems. The aim of the project is to study and test the optimal timing for loading and unloading the stored energy back to the grid, and to investigate the market-based pricing and business models for stored energy.
Energy storage systems play a significant role when realizing smart grids. They help in sustaining grid stability whenever distributed energy resources from renewable generation are integrated into existing distribution networks. Energy storage systems enable the fluctuations in the network caused by the renewable generation to be compensated quickly: the agile battery energy storage system can balance the fluctuations in a fraction of seconds. By these means, it safeguards the electricity supply in all kinds of conditions.
