Proposed Layout
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
Trusthorpe
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
