Policy and Action plans

Energy policy

Guidelines on energy conservation are being received from time to time from the

Railway Board. These are advised to the divisions and monitored. Energy

Conservation week is celebrated from 14th December to 21st December of every

year by conducting seminars, distributing booklets on energy conservation

measures.

Objectives:

216

• To have lowest specific energy consumption. • To maximize the use of renewable energy resources wherever feasible. • To identify the areas of excessive energy consumption and avoidable loss of

energy and to initiate measures to arrest the same.

Major Projects Implemented during the year 2013-14

(A) Traction power

The following major activities including energy conservation measures have been

implemented to reduce energy consumption and achieve economy in energy

expenditure during the year 2013-14.

a) Tariff containing measures

Energy tariff plays a vital role in economic and efficiency of traction system. Dual

purpose initiative has been taken to avail the incentive available on power factor as

well as reduction in demand and minimization of loss.

b) Demand side management to conserve energy

Central railway continuously monitors demand of the sub-stations with the demand

approaching/overshooting buzzers to alert the traction power controller to control

the maximum demand by way of extension of feed.

By effective energy management, the demand has been restricted to save demand

charges for Railway and thereby helping the supply authorities in managing the

system without extra burden of exceeding demand or losses.

Central Railway has issued instructions to switch off the standby transformers at the

traction sub-stations. This has resulted in minimization of losses. Central Railway

has provided capacitor bank in 17 traction sub-stations.

c) Provision of energy saving devices

Central Railway draws power from 25 kV AC traction sub-stations for traction.

Capacitor banks have been provided at 15 traction sub-stations. Since the

installation of capacitor banks, power factor has improved in the order of 0.90 to

0.99 resulting into handsome savings in restricting the power consumption. The

benefits achieved are as under:-

i) Saving in restricting the demand. ii) Saving on account of avoided losses due to improved power factor (kWh*(1-(pf1-

pf2)^2).

d) Improvement in operational efficiency by training the locomotive operation staff resulting in improvement in Specific Energy Consumption (SEC).

217

Central Railway has taken initiatives on energy efficiency in operation of electric

locomotives by –

i) Regular counselling of operation staff/drivers. ii) Provision of Coasting Boards. iii) Installation of Energy Meters on electric locomotives/EMU’s to monitor the

energy consumption. iv) Comparing the unit wise SECs and take corrective measures. V) Switching off of trailing locomotive when empty rake is hauled by MU. VI) Switching off of auxiliaries. VII) Panto lowering.

e) Introduction of 3-phase technology

Central Railway has adopted 3-phase technology resulting in reduction of about

10% to 13% energy consumption due to regeneration on AC and DC EMUs &

locomotives.

f) As per guidelines of Railway Board, Central Railway has proposed procurement of Cheaper Power through Bi-Lateral Mechanism in Maharashtra through GUVNL by open access.

g) Conversion from 1500 V DC to 25 kV AC traction

The section, Igatpuri-Kalyan, Lonavala-Kalyan, Kalyan-Thane has been converted

from age old 1500 V DC to 25 kV AC traction to improve operational efficiency and

energy savings. Work in Thane to Mumbai CST section has also been completed and

WEST CENTRAL RAILWAY

Jabalpur (Madhya Pradesh)

Unit Profile

West Central Railway (WCR) with its headquarters at JABALPUR came in to

existence on 1st April, 2003. The territorial jurisdiction of West Central Railway

stretches from Khandwa (excluding) to Manikpur (excluding) on the Mumbai-Howrah

route via Itarsi- Jabalpur and from Mathura (excluding) to Nagda (excluding) on

Delhi-Mumbai route via Ratlam forming a part of one of the important diagonal and

side of golden quadrilateral of Indian Railways. Other than this GWALIOR-GUNA-

MAKSI, BINA-KATNI-SINGRAULI, KOTA-CHHITORGHAR AND SATNA-REWA sections

are also part of WCR.

It consists of three divisions by including Jabalpur & Bhopal divisions of the erstwhile

Central Railway and Kota division of Western Railway. Along with three divisions, all

activity centers in their jurisdiction i.e. two workshops, three Loco sheds, and

Training institutes have also been made integral parts of the new Zonal set up.

The railway moves varied mix of traffic like cement , power house coal, lime stone,

fertilizers, petroleum products, steel and food grains under public distribution
