This presentation gives an overview about energy efficiency in cold storage industry in Nepal based on a GIZ study conducted in 200 industries in 2012.

1. Cold Storage Sector

2. Sector Highlight
Being an agricultural country, Nepal
produces variety of agricultural products and
these also need to be stored at low
temperature for extending their useful life.
Cold storage association has 23 members in
their list and it has reported that there are 35
cold storages in the country with an average
capacity of 3,000 MT each.

3. Observations
 Potatoes and fruits are the main products stored
 They consume only electrical energy for cooling
process
 The rate of electricity charge is subsidized 50% by
NEA
 All units have DG set to supplement the power
during power failure
 Motor loadings are not checked
 Power factor is low – none used capacitor banks
 Many incandescent lamps are used
 Air curtains are not used

5 Energy Cost NPR 31,985,995 1,476.15
Energy cost is around 37.91% of the turnover

6. Saving Potentials
Regional energy intensity could not be obtained.
The specific energy consumption has been found to be
283.53 kWh/MT of product stored
Annual storage quantity = 21,669 MT
saving potentials from ESPS audits,
= 5.93% of electrical energy
The electrical energy saving potential will be
= 0.0593*283.53 *21669 kWh
= 364,328 kWh
= 364.328 MWh

7. Areas of Potential Savings
 Compressor motor loading
 Efficient motors
 Power factor improvement
 Improvement in insulation of the cold pipelines,
storage room walls and ceiling
 More efficient belt and pulleys
 Partition of cooling areas, installation and effective
use of air curtains
 Regular cleaning and maintenance of condenser
pipes
 Replacement of incandescent lamps
 Minimization of leakages of compressed ammonia
gas
