Coronavirus Pandemic Response – Update 17 June 2020
According to Government and industry guidance concerning
the coronavirus pandemic the Accelerated Loss of Mains Change Programme
(ALoMCP) is considered necessary for the short to medium term security of
supply and ensuring network resilience. Therefore, programme delivery
continues, with the following additional guidance:
approved in Windows 1 & 2 that had a Latest Valid LoM Change Date before or
within September 2020, but had yet to complete the required works, have had
their deadline extended by three months. A further extension to 4th August has
been granted to any application that had an initial deadline of 24th March.
requirements to witness certain works and complete Sample Site Visits are
unchanged. Where DNO/IDNOs are unable to attend sites in person they have
agreed to support trials to complete witness testing and Sample Site Visits
virtually, for example by means of video calling. Contractors should engage
with the relevant DNO/IDNO for details of how to do this.
due to applicants who have already completed their work, and had a Sample Site
Visit conducted where applicable, will be processed as soon as is practicable
under current working arrangements.
Programme portal remains open for applications. We ask that the lead time
provided in new applications accommodates any estimated delay due to Covid-19
During these extraordinary COVID-19 conditions we understand
that you may be unwilling or unable to progress your ALoMCP works within the
allotted timeframe. It is our intention that the 3-month extension given should
mean that no applicant is penalised if they are unable to work within the
Government guidance or decides that the risk to them of undertaking works is
The ALoMCP will keep the situation under review and update
this response as the situation changes and as more information becomes
The purpose of the ALoMCP is to improve resilience of the
national electricity network in order to maintain security of supply across the
country. In an open letter to Network Operators, Ofgem has categorised what
activities are to be considered High Priority and Lower Priority Works and
Services to enable Network Companies to prioritise works. As the protection
modifications proposed under the ALoMCP can be considered “Planned Works
necessary for the short to medium term security of supply and ensuring network
resilience” they can be considered High Priority. Therefore, further to the
recent decision to suspend delivery of the programme, and after careful
consideration of the current government guidance, the ALoMCP workgroup
recognises that it is possible to continue with the programme whilst remaining
compliant with these guidelines.

Recognised contractor status will allow “self-certification”
(supported by evidence) works to be undertaken in the SSEN network areas as
part of the ALoMCP, without the requirement of witness testing attendance by an
SSEN engineer for sites where the existing protection device is to be replaced
by a new device or loss of mains protection function, or an existing protection
device is to be disabled.
Note: Loss of Mains settings change works will be covered
under “self-certification” supported by evidence.
To become a Recognised Contractor an individual must
complete three successful relay replacement-commissioning tests, witnessed by
an SSEN engineer and completed to a satisfactory competence level in terms of
skill, processes and procedures. If an individual believes they have already
met this requirement they may provide evidence of this, i.e. dates of 3
previous commission tests witnessed by an SSEN engineer, giving the name of the
site and SSEN engineer who was present, for SSEN to consider. SSEN reserves the
right to require further witnessing of testing.
Recognised contractor status will be granted to individual
engineers only, not to a company or other entity. Where a company has several
engineers, they will each be required to gain individual approval via the above
Once recognised contractor status is achieved, e-mail
notification will be sent from SSEN to the contractor.
Where works are carried out under the self-certification
process, a sample site visit by SSEN may be required following receipt of
evidence of completed works.
If you wish to be considered for Recognised Contractor
Status please inform the SSEN engineer present at a Commissioning Test. They
will begin a record of visits and confirm when the criteria for recognised
status has been met. If you believe you have already met this criteria please
email details of your evidence to G59ProtectionSettings@sse.com.
What is Loss of Mains
Scottish and Southern Electricity Networks is working with
National Grid ESO, the other Distribution Network Operators and Independent
Distribution Network Operators, to make sure all generators connected to our
network are aware of new requirements and are able to apply for funding to make
the necessary changes before the requirement come into force. This is called
the Accelerated Loss of Mains Change Programme (ALoMCP) and our aim is to help
generators understand the changes they must make to their equipment, to ensure
safe balancing of the grid and security of supplies.
By taking action, generators will be reducing the risk of
their generation tripping out unnecessarily. That will contribute to making
this country’s secure, reliable power supply even more resilient.
Generators are able to apply for funding if the following all
apply to their installation:
What support is there?
There is funding available to support making these changes.
But if the installation qualifies under the points above and the generator does
not make the changes by September 2022, they will be considered non-compliant
with the Distribution Code and may face enforcement action. Details of the
funding available can be found in the Payment
