Overview of Current Issues Interconnectors ‘Wind’ Charging Offshore Update HVDC Links Open Governance Embedded Generation

Embedded Generation Both embedded and transmission generators compete to sell energy to suppliers Suppliers charged for use of system on basis of net off-take from the network (i.e. demand minus embedded generation) Charges comprised of locational + residual elements Net charging introduces a GB wide benefit for EG over T-connected due to the residual element of charges (~£20kW) Two possible solutions include: Continue to charge net but implement nodal explicit access rights – i.e. remove competition between EG and T-connected Implement a gross charging regime, maintaining full competition but levelling the playing field between the two The Issue

Embedded Generation Original TADG Working Group (2007 – Chaired by Ofgem) Interaction with ‘Small Generator Discount’ – April 2011 (SLC C13) NGET pre-consultation January 2010; followed by working group meetings Maintaining competition between EG and T-connected is likely to present a more attractive proposal for consumers Charging suppliers on a gross basis removes the benefit caused by the residual; three options for how this could be implemented are: (i)Gross G+D G MW Triad and D MW Triad (ii)Gross G+D G installed MW and D MW Triad (iii)Net G+D locational and Gross D locational + residual Progress
