PERFORMANCE OF EASTERN ELECTRICITY'S DISTRIBUTION
NETWORK— CHRISTMAS 1998
Thank you for your letter of 8 March 1999. I
am certainly pleased to assist your enquiry by providing the following
information.
We have 3.3 million electricity customers within
our region, of which the following were without supply as a direct
result of the Christmas storms (the figure in brackets is for
all customers off supply and includes non-storm related faults).
| Storm | Total
|
| | |
| | |
| Friday 25 December | - |
(3,544) |
| Saturday 26 December | 6,402
| (9,952) |
| Sunday 27 December | 598 |
(4,735) |
| Monday 28 December | 161 |
(619) |
| Tuesday 29 December | 2,917
| (5,977) |
| Wednesday 30 December | 1,897
| (7,140) |
| Thursday 31 December | 1,453
| (4,239) |
| | |
| | |
| 13,428 | (36,206)
|
At the peak, 0.2 per cent of customers were without supply
due to the storms and 0.3 per cent when non-storm related faults
are included.
During this period our restoration of supply performance
was as follows:
| Duration | Number of Customers
|
|
| |
| 0-3 hours | 32,797 (90.5 per cent)
|
| 3-12 hours | 3,317 (9.2 per cent)
|
| 12-24 hours | 92 (0.3 per cent)
|
| 24-48 hours | Nil |
| 48-72 hours | Nil |
| 72 hours+ | Nil |
As none of our customers were off supply for more than 24
hours no Guaranteed Standard, or any other form of compensation
payment, was made.
It may help in your comparisons with NIE, and other electricity
companies, to know that the maximum wind speed we experienced
during this period was 59 miles per hour at 2100 hours on Saturday,
26 December 1998.
