UKPN Substation Design
• Substation Locations
~ Drivers behind the current policy
~ Minimum requirements for a basement location
~ Mandatory elements of a basement location
~ UKPN’s preferred basement solution
~ Alternative basement solutions

UKPN Substation Locations
Since 2011; UKPN’s stance regarding ‘new build’ developments has been: “The normal location for a substation, whether in a separate building or integral to a customer owned building, is at ground level”. This is a similar stance to all other DNOs.
The documentation goes on to offer a limited list of exemptions (i.e. ‘listed’ buildings); where a basement location might be considered and a process for justifying that location.
2011 – review of policies and standards by UKPN.

Substation locations ~ Key Drivers• 24hr unrestricted access
~ OFGEM ‘KPI’: Customer Minutes Lost (CML).
• Manual Handling
~ ‘Design-out’ MH of heavy plant wherever possible.
• Working at Height
~ ‘Design-out’ WAH wherever possible (e.g. cable entry).
CDM – Designing out risk – installation, maintenance and de-commissioning
19
UK Power Networks acknowledge that many sites in central London are not ‘normal’ and proposals for basement
locations are often considered and agreed.Join the Conversation@UKPNnews #Connections
Requirements enabling basement location to be considered:
• Maximum one level below ground floor
• 24hr unrestricted UKPN staff access; via a stairway that meets UK Building Regulations (e.g. no ‘companionway’ ladders)
– Without recourse to a third party (i.e. Security Guard).
– Dedicated stairway.
– Dual-locking arrangements (if necessary).
• ‘Direct’ UKPN Plant Access
– Ideally 24hr unrestricted.
– Manual Handling kept to a minimum
• Natural Ventilation Scheme
– Open to ‘free air’.
– Passive ‘Stack’ principle employed.
– Maintenance free.

UKPN’s preferred basement solution is a ‘Lightwell’ substation
< Personnel access without
3rd party involvement
Via dedicated stairway >
21
Join the Conversation@UKPNnews #Connections
‘Lightwell’ substation cont’d:
22
< Direct plant access via HIAB crane
Direct plant access with minimal manual handling >
< Open to ‘free air’< Utilises the passive ‘stack’ system< Maintenance free
Alternative basement locations:
Obviously not all projects will be able to accommodate a ‘lightwell’ scenario; in these cases meeting our requirements can be more challenging, but the complications are by no means insurmountable.
The LPN Substation Design Team can work with the customer’s design team to ensure the final result is acceptable to both parties.

In conclusion:We will work with customers to install basement substations, all examples used here are recently installed basement locations.
We will always look for a ground level location in the first instance;
A number of aspects need to be considered if we are to meet our own requirements in terms of Health & Safety and network security.
Each project requiring a substation will be assessed on its individual circumstances; providing the mandatory elements can be achieved, a basement location may well be viable.

1.5mva Transformers and Installation of Risers and
Laterals

Context
• UK Power Networks charged with stimulating and supporting a competitive market
• Market share has reduced significantly in majority of relevant market sectors
• Service delivery has demonstrably improved in recent years
• Appetite for more competitive offering is increasing
• Customers want UK Power Networks to be more flexible in offering
28

Transformers• 11kV transformer specification has typically been limited to 1MVA
– Reduced unit diversity leads to lower unit cost and simpler maintenance schedule
• Automatic loss of Connections market share to IDNOs, particularly in high land-value / physically constrained locations
• We have reviewed specification options with a number of customers to determine most useful offering
• 1.5MVA unit with 2500A LV circuit breakers being sourced
• P2/6 Compliance
29

1.5MVA sub-station
30
• UKPN are progressing this as a pilot until sourcing and G81 updates are complete
• Integral sub-station design to be progressed
– Plinth
– Layout
– Ventilation
– Fitting
• This can then be offered more widely; anticipated c. December
Join the Conversation@UKPNnews #Connections
Risers and Laterals
• 2012 decision to cease installation of Risers and Laterals in South-East and Eastern DNOs
– Has not been offered in London DNO for some time
• Recent review concluded offering new installation service
– Not to include on-going ownership
– Liability for future maintenance remains with building owner (or BNO)
• Trial basis with existing contractor
• Possible expansion if uptake is positive
