Over a one-year period, Nidec designed, procured and installed a 10 MW EFR system at the Blackburn Meadows site. Nidec’s services began with site preparation, soil analysis and drainage improvements, before moving to metal construction, assembling, testing and commissioning the battery systems.
The new BESS – the first of its kind in the United Kingdom – consists of four lithium-ion battery modules – two 1.5 MVA active front end AC/DC converters and two 900kWh battery banks. Housed in shipping containers for easy transportation and “plug-and-play” installation at Blackburn Meadows, each unit came complete with power converters, transformers, batteries and a control system. The 10 MW battery has the same power as approximately 100 automobiles. Located next to an existing biomass combined heat and power plant, it holds the same amount of energy as 500,000 mobile phone batteries.
In addition to the EFR solution, Nidec also provided HVAC, fire protection, power and energy management systems for the project, as well as a SCADA system that integrates with the national UK grid for performance and billing.
Commissioned in 2017, the battery storage allows E.On to make the best use of its renewable energy sources by harnessing the energy and having it ready for use whenever it is needed. Nidec’s innovative battery storage technology not only increases the share of renewable energy on the grid and improves the security of supply, it paved the way for other EFR projects in the UK.
