In last two OCCM, ISP informed that the case for purchasing new RTUs has been initiated by

ISP & it will be completed by 4-5 months in response to which ISP was requested to expedite the progress. The present status along with schedule for rectification of telemetry may please be provided by ISP.

In last OCC, MPPTCL informed that there is some problem in RTU at 400 KV Kirnapur.

MPPTCL (T&C) is pursuing the matter with BHEL but no significant response/action has been taken by BHEL. MPPTCL is requested to provide the current status in the matter.


It has been observed that in substations telemetered through DFE RTUs, the transformer voltage output is used for telemetry of bus voltage. This results in wrong bus voltage in case of transformer outage. MPPTCL is requested to arrange for separate MFM for telemetry of bus voltage.

Further, It has also been observed that some times the bay no. of the charged element is changed without intimation of change in the physical address of RTU elements to SLDC. This results in the wrong telemetered values to SLDC. Recently at 220 KV Nepanagar S/s, telemetry of 132 KV Pipalpani feeder was charged though existing bay of 132 KV Bahadurpur feeder without intimation to SLDC thus resulting in wrong telemetered values of both the feeders. MPPTCL is thus requested to ensure prior intimation of any change in bay or physical address of RTU elements to SLDC.

CERC has recently implemented new DSM regulation w.e.f. 1st January, 2019 and in

this regulation change of sign of deviation by the entity is made mandatory after every six time blocks or else additional charges shall be levied for each violation. Thus the accurate computation of MP as well as Discoms’ demand is essential to avoid additional charges on daily DSM charges. Any discrepancy in real time data of Generation Station /Sub stations may lead to financial burden on Discoms’ in terms of additional DSM charges. MPPTCL, MPPGCL & NHDC are thus requested to ensure the continuity of real time data to SLDC SCADA all the time and fault if any, in the telemetry system should be attended promptly. [ACTION: T&C, MPPTCL , O&M: GEN, MPPGCL, NHDC]

9.3 EXTENSION OF RGMO/FGMO SIGNAL TO SLDC/WRLDC :-The RGMO signal of Pench HPS has integrated in SLDC SCADA system & extension of RGMO/FGMO signal of following generating units is still pending:-

S.No. Name of Generating Station

Unit.No. MPPGCL response in last OCC

1 Satpura TPS 6,7,8,9 MPPGCL informed that they will explore the possibility of providing FGMO signal status & will inform SLDC within one week. However no response in the matter has been observed.

2 SGTPS 1,2,3,4 MPPGCL informed in last two OCC meetings that it is under tendering process & shall be completed within 3-4 months. However no progress in the matter has been observed even after lapse of 4 month period.

3 BARGI HPS 1,2 MPPGCL informed that equipments from BHEL have been received & commissioning shall be done during AOH of Units in 2019.

4 Singhaji TPS Phase II 3,4 MPPGCL informed that as discussed with M/s L&T, RGMO/FGMO is not required. SLDC requested MPPGCL to confirm the same in written so that the matter may be placed before WRPC. The matter has been constantly pursued by SLDC vide letter dtd. 14.02.19, 17.10.18 & 21.08.18. However no response in the matter has been provided by MPPGCL.


MPPGCL is thus requested to kindly arrange for integration of telemetry of RGMO/FGMO in RTU installed at power stations on topmost priority.
