8. Progress To Date

9. FACTS Specification complete FACTS ITT Issued and being scored Wayleaves for OHL rebuild well underway Harmonisation with works at Trusthorpe Progress to Date Trusthorpe

11. New 4.5km Overhead Line Local opposition Unintended Consequences Investment ahead of need Vs business need Compulsory wayleaves a last resort Not appropriate in this scenario
