APL O&M Mundra Send Mail to SLDC Gujarat / WRLDC at 17:39 hours on Dt.03.05.2014 Requesting to take Emergency Outage of Mundra - Sami Ckt-2 from 06:00 to 09:00 hours.
At 18:23 hours on Dt.03.05.2014 SLDC Gujarat replied if required all STOA and collective / bilateral transactions from APL shall be curtailed. It is requested that during this outage period power flow on HVDC shall be maintain 2000 MW.
At 04:16 hours on Dt.04.05.2014 APL O&M replied if system constraint is there APL will be ready to curtail its STOA / MTOA transaction.
With respect to above SLDC SIC Curtail APL STOA & MTOA to 0 MW from 09:00 hours to 12:00 hours for the Dt. 04.05.2014.
From 07:00 hors to 13:00 hours SLDC Haryana changed HVPNL requisition and back down 500 MW from APL-3 to HVPNL DC (i.e. 1470.39MW). In APL-3 TNEB & BSEB curtail to 0 MW from 09:00 hours to 12:00 hours Dt. 04.05.2014, due to this Curtailment APL-3 total schedule goes below technical minimum so APL request to SLDC SIC to restore MTOA TNEB 200 MW but SLDC SIC refused to restore TNEB as HVPNL might restore its LTOA during specific period of time.
At 08:36 hours APL RMDC sent mail to HVPNL requesting that APL will surrender 300 MW only due to curtailment its STOA & MTOA stating reason APL-3 total schedule goes below technical minimum for the time period 09:00 to 12:00 hours.
In reply HVPNL accept our request & revive 200 MW from total back down of 500MW in APL-3 w.e f 09:15 hours .But SLDC SIC denied to revive 200 MW from APL-3 due to line constrain & also threaten APL that your outage will be cancel if the above quantum will be revive for the specific time period.
