Swiss utility selects NEC Energy for energy storage development


According to a statement, the two will develop a 18MW/7.5MWh battery energy storage plant to help the utility expand its portfolio of renewable energy resources, store electricity during times when generation is high and integrate it into the main grid to meet demand during peak periods.

The energy storage system is expected to be operational by the first quarter of 2018 and will provide electricity adequate to power 400 households for a day.

The project falls under efforts by EKZ to embrace innovative energy technologies and to modernise and prepare its grid network for future business models and customer demands.

Over the past five years, the energy provider has been operating a 1MW battery energy storage system sited at Dietikon developed in partnership with ABB.

Marina González Vayá, smart grid specialist at EKZ, commented: “The store will provide regulatory power to the Swissgrid national network and thus contribute to the stabilisation of the electricity grid from Lisbon to Istanbul.”

The development of the battery energy storage plant has been approved by the municipality of Volketswil and the Swiss Federal Electric Power Inspectorate.

Michael Koller, head of Technology at EKZ, added: “More and more renewable sources of energy are fed into the grid unpredictably.

“In order to ensure grid stability, such decentralized storage facilities are gaining in importance.”

The 18MW/7.5MWh storage system is claimed to be the largest battery energy storage project in Switzerland.

Battery energy storage plant development

In early March, NEC Energy Solutions announced its partnership with VLC Energy to build two energy storage plants for UK utility, National Grid.

In a combined statement, NEC Energy Solutions said it will be assisted by VLC Energy to develop and operate 50MW energy storage plants to help National Grid sustain the stability of its grid network during peak periods. National Grid selected to have 40MW battery energy storage plant built in Glassenbury and 10MW energy storage system sited in Cleator [Read more…]
