In a recent consultation on options for forward-looking charges, Ofgem proposed to introduce the concept of Generation and Demand Dominated Areas (GDAs and DDAs) in the Common Distribution Charging Methodology (CDCM).
The CDCM governs the distribution charges that low- and higher-voltage (up to 22kV) connected users see and currently applies the same charge or credit to all users of a certain type in that network. It assumes that distribution-connected generators offset network reinforcement, which has traditionally been demand-led.
The chart this week focuses on Pixie Energy’s home city, outlining current load and generation for primary substations served by the Norwich grid supply point.
