Problems Cold Storage Operators Face
Interrupted electricity supply is a common concern in many countries, including India. While poor availability is one concern, the supply is highly intermittent. Besides, the quality also is miserable with harmonic distortions common in many places.
Running cold storage becomes highly challenging in such situations. The grid connection is 1.5 times more than normal, resulting in high costs and a higher price per unit. Since electricity supply isn’t as reliable, companies use diesel generators at a lower operating power, which refers to unit cost rising to up to Rs. 18-25.
Let’s look at the operating expenses for cold storage.
Electricity Costs
- Through grid: 50%
- Through diesel genset: 20%
- Minimum electricity charges + administrative costs: 10%
Grid Connection Charges
- DG set maintenance: 2%
- Salaries and wages: 5%
Miscellaneous running expenses: 13%
Thus, the electricity cost contributes to 62% of the cold storage’s total operating cost.
So, here, the solution is distributed generation of electricity, which refers to becoming self-sufficient in electricity. Can a solar grid tie inverter serve the need? Let’s see.
Challenges in Using Solar Grid Tie Inverter
The answer to the above question is a potential no. Why? Here are some reasons.
- Inverter Shutdown during Grid Outages: This issue arises from the anti-islanding feature inherent in all grid-tied inverters. In a power-deficient country like India, where the grid is unreliable and power interruptions are frequent, a Grid-Tie Inverter fails to provide electricity even when the sun is shining.
- Inability to Ensure 24×7 Electricity: With no storage capacity, the Grid-Tie Inverter is only functional during daylight hours. Consumers are left without power during brownouts unless a DG Set is available.
- Absence of Diesel Cost Savings: Daily operation of DG sets remains unchanged, resulting in no reduction in diesel costs and associated pollution. Additionally, the manual handling of Ammonia valves becomes necessary, as there is no provision for guaranteed uninterrupted power.
- Inefficient DG Utilization: Running DG sets on lower loads leads to carbon buildup and internal glazing, significantly reducing their lifespan and performance.
How Can a Solar Hybrid Inverter Help?
If a solar grid tie inverter cannot work or prove adequate, can a solar hybrid inverter work? Let’s see it through the following.
- Solar hybrid inverters combine grid tie and storage. That eliminates the loss of solar energy even during grid failures. Thus, there’s a guarantee of 24/7 electricity.
- The ‘Export to grid’ feature under net metering allows the transfer of excess solar power.
- No loss of energy or hassles of opening and closing of the ammonia valve.
- Assurance of quality power.
- No mechanical stress on the motor.
- Enhanced mechanical maintenance.
- Minimal to no need to run the cold storage on a DG Genset.
- ROI is estimated to be received in 3-5 years.
