CMP472: Large Embedded Generators Original Red Line Boundary Sharing Without Customer Consent

This proposal seeks to introduce a new clause in Section 17 of the CUSC to permit NESO to share the Original Red Line Boundary (ORLB) submitted by Large Embedded Generators (LEGs) with the relevant DNOs without requiring explicit customer consent. This change enables DNOs to independently and consistently verify distribution contract validity for LEGs applying for Gate 2 offers, ensuring that only projects with compliant and valid distribution arrangements progress through the gated connections process.
