This work was completed successfully last night.
All customers fed from this core mast now have protection against power cuts by a massive 7 KWh of batteries - enough to run the average home for around a day! - as well as an auto start diesel generator with a 100 litre tank of fuel.
We were keen to get this work completed before the Christmas break
**DUE TO FACTORS OUTSIDE OF OUR CONTROL, THIS WORK HAS BEEN POSTPONED FOR NOW AND IS PROJECTED TO TAKE PLACE NOW ON THE EVENING OF MONDAY THE 19TH**
IMPORTANT INFORMATION FOR ALL CUSTOMERS SERVED BY OUR CAIRN MON EARN / DURRIS MAST:
Last week we suffered a couple of faults impacting customers whose connection goes via our mast at Cairn Mon Earn near Durris.
In order to get everyone back online as quickly as possible we had to bypass our battery backup system at this site as this was the root cause of the issue.
We have since then purchased upgraded battery backup hardware and had it air freighted to us from the USA in order to minimize the time that this critical site was on reduced redundancy
Those parts have now arrived and we are keen to get them fitted as quick as possible to avoid any potential unplanned outages.
To do this we intent to go to the site this evening at around 9pm to install the new battery hardware and have the site fully protected against power cuts.
This site also has an automatic starting diesel generator however the batteries are critical for two reasons:
To keep everything running whilst the generator starts and reached operating speeds
To keep things online in the event the generator either does not start OR runs out of fuel
For this reason we have taken the decision to install the battery hardware tonight as the next available slot for us would be monday evening and we want to avoid the possibility of any unplanned outages over the weekend.
We do appreciate that this may cause some inconvenience as the outage will happen at short notice however we believe the the potential for an unexpected outage with no notice, that could last for many hours in a worst case scenario, is worse and for that reason we have decided to press on with the work tonight.
Downtime for most customers is expect to be in the region of 15-30 minutes
Thank you all for your understanding and patience during these essential works
