KiWi Power Unveils Smart Battery Storage System


UK energy storage
developer Kiwi Power has unveiled its largest behind the meter battery to date
with the completion of the 4MW / 4.8MWh Tesla battery at Cenin Renewables in
south Wales.

The multi-million-pound
smart battery system took three months to build in order to provide
firm frequency response (FFR) to National Grid after winning a two year
contract offering 24 hour availability at £19/MW per hour beginning on 1

The size of three
shipping containers, the 4 MW system took three months to build and will
provide balancing services to National Grid to regulate the frequency of
Britain’s electricity network.

KiWi Power said it
“marks a significant milestone in the application of ‘behind-the-meter’ smart
battery technology in the UK, with capacity to store enough energy to power
thousands of Welsh homes when needed, helping to build a low carbon economy in

The system is located
at Cenin Renewables at Parc Stormy near Bridgend, a 20-acre cluster of
integrated clean energy technologies that includes a solar farm, an anaerobic
digestion plant and a wind turbine.

“This is all about
having green energy in reserve and we are delighted to play our part delivering
a reliable, sustainable power source whilst providing local economic
development and helping Wales reach its low emissions targets," said Martyn
Popham, Cenin managing director.

He added: “Smart
batteries are both green and cost-effective, reducing the need for inefficient
backup power stations by allowing excess energy to be stored and used when the
sun isn’t shining and the wind has stopped blowing".

Yoav Zingher, chief
executive of KiWi Power, said the facility “is an exciting addition to KiWi Power’s
battery portfolio, and a key part of our strategy to develop, finance, build
and monetise the highest value battery systems on customer sites across

“Our state-of-the-art
technology enables large power users like Cenin to reap the rewards from
battery energy storage, with no upfront investment or risk to them, reducing
their bills and their carbon footprint".
