The two nearest fire stations to us are retained firefighters only (
so ~40 minute response time) and the nearest hydrant to the proposed
BESS site is on a 3" pipe private pumped well water with a 6' head of
water.
Firefighters are expected to put these things out when/if they catch
fire but are not even a statutory planning consultee at present.
They can respond anyway, as can any member of the public regarding this issue. I wonder if the site would have its own fire-fighting capability anyway?
The modules have built in Novec fire suppression using a fluoro ketone.
(next best thing to Halon but much less damaging to the ozone layer)

However, it doesn't always work and the resulting conflagrations are
very spectacular once a container full of Lithium ion batteries goes
into thermal runaway - pre-ignition dense white toxic fumes or fire
(only happened once in the UK so far to my knowledge - in Liverpool).
The vapour explosion from that one fortunately occurred before the fire
brigade arrived on site. Luckily no-one injured.

(BBC exaggerate the time taken to actually put it out)
Once a Lithium battery module is on fire there is no way at present to
put it out - only option is to cool its neighbours with copious amounts
of water and wait for the ferocious fire to burn itself out in ~5 hours.
Then about 2-3 days of babysitting the remains in case it restarts.
The cute 3D fly by shows a US style toytown water tower that would last
all of 10 minutes with a high volume pump attached to it. The 2D plans
from the original "consultation" show no water supplies on site at all.
We know that the planning applications for Rounton and Thirsk 1GW BESS
have been submitted to the County Council and are awaiting validation.
Both are on rural agricultural heavy boulder clay fit only for grazing
(not protected green belt).
Each will be a rural remote monitored site with roughly 900 standard
shipping container sized modules full of batteries plus a 1GW substation
to link into one of the 400kV lines nearby. A similar proposal is also
in play near Thirsk and encountering similar levels of opposition.
Security will be the typical combination of CCTV, razorwire heavy
industrial fence and electric fence (like any other GW sub station).
