2017-02-25 08:44From : Power System Manager - National Grid Electricity Control Centre. NATIONAL ELECTRICITY TRANSMISSION SYSTEM WARNING: Inadequate Localised Negative Reserve Active Power Margin. In accordance with Grid Code BC1.5.5, National Grid hereby gives notification of Inadequate Localised Negative Reserve Active Power Margin (NRAPM) in the following regions: Kendoon/Glenlee/Tongland (Galloway Export) . This Inadequate Localised NRAPM is valid for the period from 08:30 hrs on 25/02/2017 to 15:00 hrs on 25/02/2017. The margin by which the anticipated active power output of generation connected to the transmission network in the region(s) highlighted above (or to distribution networks so connected) can be reduced in respect of the declared inflexibility of such generating plant is considered to be insufficient for the specified period. The Bid Volume Shortfall is 22 MW. Would all Generators, in respect of Power Stations connected to the transmission network in the region(s) highlighted above (or to distribution networks so connected), please revisit Balancing Mechanism submissions to ensure that any implied inflexibility is accurate and in line with intended operating plans during these times. Should the forecast conditions continue to exist then National Grid may be forced to invoke the provisions of Grid Code BC2 with regard to the desynchronising of inflexible plant. The situation will be reviewed again by National Grid at 14:30 on 25/02/2017 and an update issued. Notification Issued at 08:40 hrs on 25/02/2017 Issued by Natasa Dinic National Grid Electricity Control Centre.
