Introduction Design and Commissioning Workshop:
• Improve design submission content
• Better communication with ICP on design submissions
• Obtain a clearer understanding of design submission requirements
Main objective is to meet our ICE incentive 23.18 to help improve EHV design submissions at 33kV and 132kV

Beige input cells:
Standard Review sheets guide Customer's of UK Power Networks are invited to follow the order in this list when developing a Q.A review sheet: 1. Starting a new file Start by either copying in or filling in the drawing name and drawing numbers in the Index sheet. Please enter this data into the beige input cells (as shown to the right) on the Index page. When you have done this the spreadsheet should resemble the following figure: Once you have populated the beige cells press the 'Add New Sheets' button. This will automatically generate the appropriate number of sheets. 2. Adding new drawings to an existing file When new drawings become available these can be added to the end of the existing set of drawings . To do this either copy in or fill in the new drawing names and numbers and then click 'Add New Sheets' button. It would be preferable if the numbers and titles of all drawings were filled in in advance irrespective of whether that are included in a particular submission. Once the Index sheet completed and working as it should, the UK Power Networks Design Assurer will proceed with the comments in the corresponding sheet. Customer's are invited to respond to comments in the relevant sections of the relevant drawing sheet. 3. Checklist Although NOT AN EXHAUSTIVE LIST, this checklist can be utilised to assist designers in ensuring all salient items are considered within the design, and what UK Power Networks consider form part of the contestable design. F.A.Q Passwords a.- Modifying the structure of the file As a protection measure to keep the standard presentation of this file, in order to delete/modifiy columns/rows it is necesary to introduce a password, which initially is set as: bpi Tom James UK Power Netwoks

• UK Power Networks harmonised civil layout:
• EDS 07-0020 provides typical building size and foundation design
• Can be of masonry, GRP, elevated composite cladding or steel containerised construction – TBC following Asset Management approval
• Looped connections to be of masonry construction
Examples of good workmanship • Elevated containerised GRP buildings….
Benefits…..
• Minimises sub structure excavations / off site disposal • Raises building above any known flood level • Removes water ingress into any basement areas • Removes Type B confined space • Easier terminations into switchgear/greater working
area/benefit of natural light • Containerised building constructed and fitted out in
controlled environment, and delivered as a ‘plug and play’ unit
• Minimises on-site trades
Steel Containerised Building
• Currently under going prolonged trial with a view to gain Asset Management approval. Benefits as GRP building seen previously
• Install Video
Duct Sealing Systems
Sealing of duct penetrations has been a historic concern with these buildings. We have seen a number of contestable installs utilising a cast-in duct system (Hauff Technik) which has proved to be one of the better duct installs we have seen. Although more expensive than UK Power Networks approved ‘Rayflate’ system, it is installed with the concrete base and guarantees a prolonged seal.
Door Locks
UK Power Networks approved GRP supplier is Morgan Marine. The door/lock furniture used is Mico Tindall, which historically proves difficult to retro fit UK Power Networks approved Locken lock. A local ICP has modified a Locken barrel which fits into the Mico Tindall door furniture. This therefore avoids lock-out boxes.
Design Kits
UK Power Networks have been approached by an ICP to pre-approve a typical 2-panel t’eed connection. Work upfront approving a typical “design kit” saves programme time and rejections on future schemes. This pre-approval covers all aspects from building, foundation, electrical, cable etc., with only site specific elements requiring design assurance (geotechnical, FRA etc.).
Drones
Other areas of improvement
Over the past 12 months we have seen a significant improvement in the following areas • Landing platforms/access paths • Access roads/turning circles • LV supplies/change over socket • Satellite install • General workmanship
Innovation
UK Power Networks pride themselves on innovation and are keen to obtain any innovative ideas which could assist in reducing cost, programme time, Health and Safety etc.
What can you offer…………
EHV Electrical Design Submission
• A typical EHV Design submission is:
• 33 or 132kV connection via tee or loop to overhead or underground network
• Predominately generation or storage but can be demand
Can include more complex 11kV connections comprising metered switch panels (not RMUs)
Position of CT’s
Useful Site Information
• Cable/multi core sheets are required to be produced and provided in .pdf as well as excel format.
What issues do you have with the design submissions?
UK Power Networks EHV New Demand and Customer Connection Commissioning Requirements
Why Test and Commission assets on site?
• Ensure integrity and safe operation of assets Which in turn: Protects staff and third parties from undue exposure to
harm Protects customers from un-planned network events Maintains supply to customers upstream of network
faults Meets the operational needs and philosophies of the
asset owner Electrical Safety, Quality, Continuity regulations 2002

26
Inspection and Test Plan (ITP)
• Formal plan detailing the Inspection and Testing regime required for the project
• Thought should be given to key elements of the build stage to capture all inspection points prior to DNO formal Inspection oThis should include: oICP Civil signoff, building entry waterproofing etc. oElectrical signoff, equipment DNO approved, DSR
compliant etc. oTest / Commissioning plan approval, full design

Test / Commissioning Engineer Assurance
knowledge for relevant system voltage • Familiarity of programming / test equipment • Provision of sufficient time and resources to carry out the
commissioning works safely, accurately and completely • Risk of prolongation of testing, jeopardising connection
dates.
28
ECP 11-0001 Grid and Primary Installation and Commissioning Requirements
• 4 Design Consultation • The design shall be subject to peer review during
development and verification on completion. • All designs shall allow for full functional testing before
schemes are energised and for future maintenance testing
29
• 5 Commissioning Plan • A commissioning plan detailing the commissioning works
shall be submitted to UK Power Networks Project Manager before starting the site commissioning activity. The plan shall be developed by the appointed Commissioning Engineer responsible for the project.
• UK Power Networks Project Manager and the UK Power Networks appointed Witness Engineer shall review the plan before the commissioning works begin.
30
Commissioning Plan
To Include: • Scope of works – details of systems and plant items to be tested. • List of engineers involved in the commissioning works • Programme showing logical sequence of tests and a description of
these tests • Configuration of relay settings and files – including who will install
them • Agreed list of tests to be omitted and the justification for this (e.g.
factory timing tests or tests that may be impractical). • References – list of drawings and documents • Test results format – UK Power Networks in-house style or
contractor style. • Instrument calibration – assurance that all instruments and test
equipment are calibrated, in date and fit for purpose.
31
• 9 Test Results • The cost and effort of carrying out commissioning can be
wasted if the results are not recorded in a consistent and usable manner. As a minimum requirement all recorded results shall be stored securely on site.
• The test results shall be those directly recorded during testing and not transcribed at a later stage. A paper copy shall remain on-site at all times.
32
• 9.3 As-built Drawings and Commissioning Records • Two copies of the drawings and a full drawing schedule
are required during on-site commissioning work. 1. The first copy shall be marked up as changes take
place and along with the commissioning test records shall remain on site at all times.
2. The second copy shall be marked up to enable the as-built drawings to be created and stored electronically.
• Once the paper copies of the as-built drawings are returned to site all earlier versions shall be removed.
