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
