NEC to supply 18MW energy storage system to major Swiss utility

Published 07 September 2017

NEC Energy Solutions, a wholly-owned subsidiary of NEC Corporation, is supplying Elektrizitätswerke des Kantons Zürich, Switzerland (EKZ) with an 18 MW, 7.5 MWh GSS Grid Storage Solution.

Once completed in early 2018, this project will be the largest battery energy storage system in Switzerland. It will be owned and operated by EKZ, one of Switzerland’s largest power distribution companies.

“We strongly believe that battery storage will play a key role in tomorrow’s power networks. With this first large-scale commercial battery storage project performing primary reserve in Switzerland, we’re taking an important step towards a reliable and sustainable energy future,” said Marina González Vayá, project manager for EKZ. “NEC ES’s fast, flexible energy storage product proved to be the best solution to complement conventional power production assets such as pumped hydro storage and thermal generation resources in the primary reserve control market.

EKZ has an excellent track record with energy storage since 2012 with their 1 MW energy storage project in Dietikon, which became the first active battery energy storage system in Europe in the primary reserve control market without the backup of a conventional power plant. The new 18 MW battery energy storage system will be built at an existing substation in Volketswil, near Zurich, and will have the capacity equivalent to the daily electricity consumption of 600 average four-person households.

“We are very pleased that EKZ has chosen NEC for Switzerland’s largest energy storage project,” said Adam Briggs, Chief Commercial Officer for NEC Energy Solutions. “EKZ, like other customers around the world, is putting their trust in NEC to deliver superior, end-toend energy storage solutions from concept to design, installation, commissioning and servicing to ensure the maximum return on investment for the life of their system.”
