Uniform Network Code (UNC) 504: Demand Side Response (DSR) Methodology Implementation

UNC504 introduces a gas demand-side response (DSR) mechanism into the UNC. This mechanism allows large consumers to make gas available to National Grid at times of system stress. This follows Ofgem's approval of National Grid’s DSR methodology on 21 September 2015.

The Authority approved this modification on 2 February 2016.
