Progress To Date

• FACTS Specification complete• FACTS ITT Issued and being scored• Wayleaves for OHL rebuild well underway• Harmonisation with works at Trusthorpe

Progress to Date

• Local opposition

• Unintended Consequences

• Investment ahead of need Vs business need

• Compulsory wayleaves a last resort

• Not appropriate in this scenario
