Representative of POWERGRID informed that POWERGRID was installing PMUs at various sub-stations of central and state sector utilities under URTDSM Project. There was space problem in NTPC- Dadri for installation of PMUs at control centre. Matter was pending since long back as supply of PMUs was made in Jan’2016 and installation was pending due to space issue, earlier NTPC informed that works for extension of existing control centre will be taken up and then PMUs can be installed, however space is yet to be provided by NTPC for installation of PMUs. Representative of NTPC informed that extension work of building at Dadri was going on and work would be completed by end of Feb’ 2018, then POWERGRID can install PMUs in Dadri NTPC control centre.

( Action: NTPC, POWERGRID; Time line: Feb,2018)

5.1.2. URTDSM Status: Representative of POWERGRID informed that materials for PDC had been supplied in all control centres. Installation has been completed except NLDC, Jammu & Dehradun SLDCs which would be completed by end of Dec, 2017. SAT at some of the constituents was going on. Latest status is enclosed at Annexure-V. All constituents were requested to nominate and post at least 2 nos. of officials for WAMS system who had taken training on the PDC system. The sub-committee expressed concern over inordinate delay in implementation of the URTDSM project and advised POWERGRID as well as other concerned utilities to take necessary action for completion of the project in all respect by March,2018.
