Hyderabad Metro MD outlines Power requirement for Metro Rail

Hyderabad: Each Metro train will consume as many as 450 kilowatt hours Kwhrs/units) per trip in Corridor-I (Miyapur-L B Nagar) and Corridor-III (Nagole-Shilparamam), whereas it will consume about 300 Kwhrs (units) per trip for Corridor-II (JBS-Falaknuma) due to less distance.

The maximum power demand requirement works out to 125 mega watts (MW).

Giving details about power requirements for the Metro Rail project, HMR Managing Director N V S Reddy said that power consumption by the Metro Rail system will have two major components ie, for train services (traction purpose) and for auxiliary services (at stations, depots, OCC etc).

The total consumption per day for both these services is estimated to be 7.63 lakhKwhrs (units). The estimated annual consumption for the Hyderabad Metro Rail system for the next 10 years is as under:

For 2014-15 it will be 520 annual consumption in lakh Kwhrs/units, 2015-16 (914), 2016-17 (1,856), 2017-18 (1,897), 2018-19 (1,982) 2019-20 (1,981) 2020-21 (1,981) 2021-22 (1,982), 2022-23 (1,982) and 2023-24 (2,865).

This energy consumption has been arrived at after taking about 30 per cent saving in power consumption due to incorporation of sophisticated “regenerative” braking system in Metro trains and other energy conservation measures adopted, he added.

This apart, power consumption required for the malls, multiplexes, restaurants, offices and other facilities which are expected to come up in the real estate being developed at select Metro stations and depots is also projected by the concessionaire LTMRHL for the next 10 years.

Power supply to the Metro Rail network is directly received from Telangana Transco at four dedicated 132 KV receiving sub-stations located at Uppal and Miyapur Metro depots, Yusufguda and MGBS. Enough redundancies have been built into the metro power supply network for ensuring reliable power supply in case of failure of equipment and also for extension of feed from one RSS zone to another RSS zone in case of any problem.

The maximum power demand requirement works out to 125 mega watts and this will be supplied to these four receiving sub-stations. Uppal RSS has already been energised, Reddy added.
