1. State aid requirements

3. Introduction to State aid
3
• State aid is triggered if the use of public resources favours certain ‘undertakings’
which distorts competition and affects trade between Member States
• State aid can take a wide range of forms, including: grants, loans, benefits in
kind - or even an announcement of intention to grant aid.
• Projects must comply with the European Commission’s ‘Broadband Guidelines
2013’ which outline their policy for applying State aid rules to broadband
projects
• UK has secured an ‘umbrella scheme’ from the European Commission
• Decision sets out the criteria for compatible projects under a
scheme
• BDUK’s National Competence Centre assures individual projects

4. • Broadband Guidelines and NBS 2016 define NGA qualifying
technologies
– FTTP, HFC (DOCSIS 3.0), FTTC, and Fixed Wireless Access (configured
appropriately)
– Must be capable of delivering access speeds over 30Mbps
• Where part of a subsidised intervention a “step-change” in
capability must provided and this includes
– At least a doubling of speeds to a significant proportion of the
uplifted premises
– Provision of wholesale access to the passive and active network must
be made available to third parties

5. BDUK Role in NGA Assessment
5
Suppliers/Bidders
BDUK
Before ITT Launch
• Approving release of OMR and Public
Consultation responses
• Supporting NGA Technical Assessment
of supplier responses to Local Bodies
Approval of the Intervention Area to
enable release of the ITT
After Bid Submission
• Assisting Local Body with solution NGA
compliance assessment
• Ensuring wholesale access
requirements are met including
acceptable pricing
• State aid approval

8. Topic Evidence OMR BID
30Mbps capability For example:
a. Evidence that physical/technological constraints are
accounted for the planned coverage area (e.g. transmission
line characteristics, radio propagation etc.); and
a. Description of the network design’s upgradeability to support
30Mbps in future; and
a. Manufacturers’ product descriptions and configuration
manuals; and
a. Evidence of a commercially offered NGA-compliant 30Mbps
product (e.g. on a web-site).

• Statements supported established theory and practice
– consideration of likely realistic real-world performance
– including critical evaluation of any marketing or manufacturer claims
• Actual performance measurements from existing or comparative
networks
– where possible
• Analysis with supporting calculations and diagrams
