IGT165 Rejected - Independent Shrinkage Expert and Independent Shrinkage Charge
Summary
Ofgem has rejected modification proposal IGT165, which would have introduced an Independent Shrinkage Expert and Independent Shrinkage Charge to the IGT Uniform Network Code. The proposal was submitted by OVO Energy in September 2025 to incentivise emissions reductions on Independent Gas Transporter networks. Ofgem's decision concludes the modification assessment process without adopting the proposed changes.
What changed
Ofgem has rejected modification proposal IGT165, which sought to establish an Independent Shrinkage Expert and Independent Shrinkage Charge within the IGT Uniform Network Code. The proposal, submitted by OVO Energy in September 2025, aimed to create financial incentives for reducing gas shrinkage (unaccounted-for gas losses) on Independent Gas Transporter networks.
Affected parties including IGT network operators and gas shippers will not face new obligations under this proposal. The rejection means the current UNC arrangements remain unchanged. Industry participants should note Ofgem's preference for maintaining existing shrinkage management frameworks rather than introducing new expert-based mechanisms or separate charge structures at this time.
