UK LDES Cap & Floor to Open in April

Technical Decision Document published by Ofgem ahead of first application
window opening

 

Invinity Energy Systems plc (AIM: IES) (AQSE: IES) (OTCQX: IESVF) a leading
global manufacturer of utility-grade energy storage, welcomes the release of a
Technical Decision Document
(https://www.ofgem.gov.uk/decision/long-duration-electricity-storage-technical-document)
("TDD") by Ofgem, confirming key final details of the UK LDES Cap & Floor
scheme.

 

The Company is extremely pleased with this development, as it reinforces the
critical role long duration storage solutions like Invinity's could have in a
future low-cost, highly reliable UK electric grid.

 

As anticipated, eligible technologies have been split into two application
routes: Stream 1, which will focus on most-mature technologies (specifically
Pumped Hydro Storage ("PHS")), and Stream 2, which will be dedicated to
proven, innovative technologies such as flow batteries.

 

The TDD contains a number of important confirmations which underline the
suitability of Invinity's technology and an appropriate development pathway
for the scheme, including:

 

·    A two-month application window which will open in April 2025;

·    An indicative total capacity of between 2.7 and 7.7 GW;

·    A minimum 8-hour storage duration, (increased from 6 hours under the
previous guidance);

·    A minimum project size requirement of 400 MWh (increased from 300 MWh
under the previous guidance);

·    A 25 year project life target with no degradation of asset
performance; and

·    A programme floor that is intended to support returns on invested
capital, including both debt and equity.

 

The TDD has further confirmed the Company's expectations regarding
eligibility, including the exclusion of projects that can already be deployed
without support, and flow batteries being one of only three technologies
currently expected to participate within Stream 2.

 

Finally, the TDD has confirmed that there will be two delivery tracks with
entry into service required by 2030 and 2035. The Company expects that its
established manufacturing capability in the UK will enhance its ability to
deliver as part of the first delivery track, giving it an advantage over
solutions with a longer delivery timeline.

 

With the TDD published, the Company is looking forward to continuing to engage
with numerous developers looking to submit bids within the first application
window. This news follows the announcement in February that Invinity and
Frontier Power have partnered
(https://polaris.brighterir.com/public/invinity/news/rns/story/rynkd7w) to
submit up to 2 GWh of bids into the scheme.

 

Jonathan Marren, Chief Executive Officer at Invinity said:

 

"Yesterday's announcement firmly underlines the importance of longer duration
energy storage for the UK's future energy system. Our vanadium flow batteries,
if deployed at the scale envisaged by the LDES cap and floor scheme, will
enhance UK energy security while helping to lower costs for consumers and
bring a host of wider economic benefits including the creation of new 'green'
jobs in the UK.

 

"We are delighted that we continue to engage deeply with the teams at DESNZ
and Ofgem in respect of the vital role LDES has to play in the UK's energy
future and look forward to our proven, Made in Britain vanadium flow batteries
playing a significant role in the country's future, clean, low-cost electric
grid."
