Further to the announcement on 12 March 2025
(https://irtools.co.uk/88/story/03585594-b169-4c81-852f-37764fd389bd) ,
Invinity Energy Systems plc (AIM: IES) (OTCQX: IESVF), a leading global
manufacturer of utility-grade energy storage, is pleased to confirm it has
received a formal Notice to Proceed ("NTP") from STS Group in respect of a
10.8 MWh ENDURIUM battery system for delivery to a project in Hungary.

 

10.8 MWh of ENDURIUM batteries will be installed alongside a large-scale solar
PV array as part of a large scale solar plus storage project in western
Hungary. The project is supported by the European Union and is expected to
receive debt funding from a major European bank. With Notice to Proceed now
issued, Invinity is due a downpayment, allowing the manufacturing and order
fulfilment process to commence ahead of shipment later this year.

 

STS Group (https://stsgroup.hu/en) is an engineering, procurement and
construction (EPC) company based in Hungary, specialising in the design,
development, commissioning and operation of renewable energy-based power
plants, hybrid power plants, substations, switching stations and transmission
lines. STS has worked with Invinity since 2023 and is considered a pioneer of
non-lithium energy storage solutions in the region. The company, which was
founded in 2002 and has completed over 100 projects across Hungary, previously
purchased and installed a 1.5 MWh VS3 battery in March 2023.

 

Jonathan Marren, Chief Executive Officer at Invinity said:

 

"Receiving NTP on this project is the final milestone and now allows us to
progress to manufacturing and ultimately delivery of the batteries, confirming
the first commercial deployment of ENDURIUM in Europe.

 

"This is an important event for Invinity both from a commercial perspective
but also financially in providing a material portion of anticipated 2025
revenues."
