ENERGY SAVINGS THROUGH
SUPPLY TRANSFORMERS
How to save £50,000 with a
single infrastructure decision

2. • 70yrs old family run SME in
3rd generation
• Transformer & switchgear
suppliers to industry
• Pioneers of super low loss
amorphous technology
(Wilson e2)

3. 3
Energy Efficiency Savings – Only inside the
building?

4. 2.9%
Energy generated
wasted through
transformer losses*
4
*EU27 (2008) losses amounted to 93.4 TWh
Transformers are silent energy guzzlers

5. 5
Supply transformers – time and again overlooked

6. Tougher design specifications for
transformer losses
• Tier 1: Effective since 1st July 2015
• Tier 2: Effective from 1st July 2021*
Applies to transformers “placed into the
market or put into service” anywhere
within the European Union.
*Wilson e2 exceeds 2021 loss requirements
6
EU Eco Design Directive Transformers

7. UK’s first super low loss amorphous
transformer
• Amorphous metal core
• Low current density conductors
• Lowest combined losses
• Exceeding Tier 2 (2021) Eco
Design Specifications today

12. Can you afford to burn over £3,700 a year?
1x infrastructure
replacement
= Energy Savings
+ Network Resilience

13. 6.4% voltage reduction
Reduced transformer losses
• 6% electricity reduction
• “Install & forget solution”
• Annual savings: £31k
Wilson e2 transformer replacement – UHSM

14. WILSON E2 TRANSFORMER REPLACEMENT
– UNIVERSITY OF WARWICK
“It appealed to us to select the product with the best
energy efficiency onto our estate, further given the
availability of 2021 compliant transformers for what
was in effect only a modest increase in capital cost
over that of a 2015 compliant version, it was in
reality a “no brainer” to select the e2 for two
recently completed substation upgrade
projects.”

successfullyintegrated in an efficient way?”

21. UEA Building Design Guide
PhilHuntMSc CEng MCIBSE
Head of Sustainability, Utilities and Engineering
Estates and Facilities Division

22. Format
• The Design Guide is published in multiple Parts,with each part
covering a specific discipline or area of design responsibility
• It describes the UEA’s strategicand specialist requirements
• It sets out the ‘gold standard’
• Structuredto accord with RIBA plan of works – earlier parts set
out design philosophies and principles – latter parts for detailed
design
• Includes very little process so it can be used by different project
delivery teams, e.g. major works, minor works or to inform
maintenance activity, etc.
• Updated annually

23. Application
• Our framework consultantsand contractorsare contractually
obligatedto read and understandthe Guide – before
attendingStage 0 project meetings
• Used to developbriefs and then specifications/employers’
requirements, with the assistance of the UEA Engineering
Team
• Deviationmust be approvedby the UEA Engineering Team
• Design risk remainsexternal
