GC0090 – HVDC Implementation Workgroup 1
Headline Report
Meeting: 1
Date: 18/09/2015
Location: National Grid House, Warwick
Attendees: See below
Agenda:
• Introductions
• Terms of Reference
• DECC/Ofgem Update
• ENC and HVDC code overview
• Project Plan
DECC/Ofgem update
DF confirmed the status of the three connections codes.
RfG was accepted by EU member states in July 2015;
HVDC was approved on 11/09/15; DCC will follow,
probably in October 2015. The counter point to HVDC, the
SO code, was also flagged for attention. This code will be
considered at Cross-Border Committee in November.
DF flagged the need to progress implementation in a timely
manner to assist understanding of compliance for HVDC
provisions new vs. existing. This was endorsed by the
whole workgroup.
Introductions
JR explained that the ‘final’ HVDC code was being
AT welcomed the group to the meeting, and queried in
advance who had been part of the ENC work and/or a Grid translated and tidied. He requested any spelling or
grammatical errors spotted by members could be flagged
Code working group in the past.
directly to him for submission [ACTION – All/JR].
The group has a broad range of experience and interest,
but the absence of OFTO stakeholders was noted
particularly. The workgroup members agreed to approach
any contacts they knew in this area [ACTION – All].
Terms of Reference
AT reviewed the GC0090 ToR. RJW flagged that the link
between the three Grid Connections codes was already
captured, following GCRP request. In reality, this link will
be managed by National Grid in their co-ordination of all
the ENC workgroups. Any resulting modifications will be
similarly co-ordinated, though the approach on this will be
confirmed formally by NGET [ACTION – AT/RJW/AJ].
GG requested that the ToR consider removal of Grid Code
text which exceeds the requirements of HVDC for new
parties. There was some hesitancy from NGET on this
point, given the Grid Code applies to existing users. This
will therefore be reconsidered during code mapping and
further implementation workgroups.
On the ToR, JN sought to clarify how any STC
consequential changes would be managed. RJW stated
that NGET would also co-ordinate this, given its Code
Administrator responsibility for that code as well as Grid
Code. It would not be in the scope of GC0090 given its
Grid Code focus, but it could advise on any STC
modification. RJW/AT have an existing action to advise the
STC Panel of the HVDC code [ACTION – AT/RJW]. AJ
clarified which GB code would be applicable to HVDC’s
‘affected parties’.
ToR would be recirculated after the meeting, and the
workgroup were invited to provide any adjustments via
tracked changes. [ACTION – RJW/ALL]

ENC Overview/Workgroup Lessons Learnt
RJW explained the evolution of the ENCs, and the path for
implementation favoured in GB. The key lessons learned
from RfG workgroup GC0048 and MODIS implementation
were outlined – particularly timeliness and transparency.
RJW flagged particularly the need for collaboration at
workgroup, and an equitable split of owning actions
RJW agreed to circulate the web page link for GC0048
documents for information (see below).
HVDC code overview
AJ clarified the intent and scope of the HVDC code. There
was considerable discussion on the applicability to
Embedded DC-Connected PPM modules (as per Article
XYZ), and the supporting process for TSOs to apply this
via CBA and NRA approval.
YA offered to provide a response paper SSE had issued to
ENTSO-E on the application of the code; RJW would
circulate to the workgroup [ACTION – YA]. The group were
also aware of a presentation from Darren Chan to JESG in
2014 which provided some clarity on the scope of the
code. RJW agreed to find this and circulate [ACTION –
RJW].

One member made reference to the IOTPE, which was felt
could overlap with the requirements of HVDC. AJ was
aware of this and agreed to seek further information and
present back to the workgroup. [ACTION – AJ]
GC0090 – HVDC Implementation Workgroup 1
Headline Report
The workgroup agreed that processes for
compliance/derogations/Cost Benefit Analysis (CBA) etc.
are likely to be consistent for all three connection codes
(reiterating the need for cross-code coordination).
The workgroup agreed a Code Mapping workshop should
happen sooner rather than later to assist implementation
work. AJ took an action to construct this, flagging
dependencies on existing GC work and consistencies with
other ENCs [ACTION – AJ].
GG raised the concept of multiple TOs (a GB issue), and
DF confirmed the approach on this would become clear in
the next month or so. It would be considered at JESG in
September.

In order to provide clarity to users, the workgroup agreed
that compiling HVDC requirements in the Grid Code in a
dedicated section would help, with limited references to
other sections where necessary.
GG was particularly keen that, as with RfG, that new
processes were explained full in the Grid Code too (e.g.
CBAs/derogations etc).
Again, there was clear intent amongst the workgroup to
progress implementation work as much as was possible
(legally) in good time to provide clarity to
users/manufacturers.
Project Plan
CR explained the basic template for the GC0090 project
plan, which evolved from RfG and her role in co-ordinating
implementation planning for NGET.
The key milestone was two and three years after entry into
force. The two year date, which again the workgroup
expressed as a worst case scenario, was for clarifying
compliance requirements on new vs. existing users. Three
years is when the Member State as a whole needs to be
compliant with the legislation.
The workgroup then discussed setting meeting dates for
the remainder of the year. It was agreed to schedule a two
day meeting to combine a workgroup meeting and a full
code mapping. RJW to circulate proposed dates ASAP on
this. [ACTION – RJW]
