Question 1

How accurate is this GUVNL bill calculator?

Accepted Answer

Our GUVNL bill calculator uses the latest 2025 tariff rates published by Gujarat Urja Vikas Nigam Limited. The calculations include energy charges, fixed charges, FAC (Fuel Adjustment Charges), electricity duty, and meter rent. However, actual bills may vary slightly due to monthly FAC adjustments, rebates, or additional charges not covered in standard calculations.

Question 2

What is FAC in GUVNL bills and how is it calculated?

Accepted Answer

FAC (Fuel Adjustment Charges) is a variable component in GUVNL bills that adjusts monthly based on fuel costs for power generation. The FAC rate varies between ₹0.50-1.20 per unit depending on market fuel prices. Our calculator uses the average FAC rate of ₹0.85 per unit for estimation purposes.

Question 3

How do GUVNL tariff slabs work for residential consumers?

Accepted Answer

GUVNL uses a progressive slab system for residential consumers: 0-100 units at ₹3.20, 101-200 units at ₹4.10, 201-300 units at ₹5.40, 301-500 units at ₹6.30, and 501+ units at ₹7.20 per unit. Fixed charges range from ₹25-85 based on sanctioned load, plus meter rent of ₹25 and electricity duty of 7%.

Question 4

What are the benefits of solar net metering in Gujarat?

Accepted Answer

Gujarat offers attractive net metering benefits where excess solar power generated is fed back to the grid and credited to your GUVNL account. You get credit at the same rate you pay for electricity consumption. The net metering policy allows systems up to 1 MW capacity for residential consumers, making solar highly viable in Gujarat's sunny climate.

Question 5

How can I reduce my GUVNL electricity bill effectively?

Accepted Answer

Key strategies include: 1) Installing LED lights (80% savings), 2) Using 5-star rated appliances, 3) Setting AC to 24-26°C, 4) Installing rooftop solar panels, 5) Using BLDC fans instead of regular fans, 6) Unplugging devices when not in use, and 7) Using time-of-day meters for industrial consumers to benefit from off-peak rates.

Question 6

What is the difference between sanctioned load and contract demand?

Accepted Answer

Sanctioned load is the maximum power (in kW) that your electrical installation is designed to handle, applicable to all consumer categories. Contract demand is specifically for industrial consumers and represents the agreed maximum power that the consumer will draw from the grid, used for calculating demand charges at ₹160 per kW.

Question 7

How does Time of Day (TOD) tariff work in Gujarat?

Accepted Answer

TOD tariff is applicable for consumers with sanctioned load above 20 kW. Peak hours (6-10 AM & 6-10 PM) have higher rates, normal hours (10 AM-6 PM) have standard rates, and off-peak hours (10 PM-6 AM) have lower rates. This helps consumers save by shifting non-critical loads to off-peak hours.

Question 8

What additional charges are included in GUVNL bills?

Accepted Answer

Apart from energy charges, GUVNL bills include: Fixed charges (based on load/demand), FAC charges (monthly variable), Electricity duty (7% of total), Meter rent (₹20-50), and category-specific surcharges. Late payment attracts additional charges as per GUVNL tariff schedule.

Question 9

How do I calculate my potential solar savings in Gujarat?

Accepted Answer

For Gujarat conditions: 1kW solar system generates approximately 4.5-5 units daily (1,600-1,800 units annually). With average GUVNL rates of ₹5-7 per unit, a 1kW system can save ₹8,000-12,000 annually. Installation cost is around ₹60,000-70,000 per kW, giving a payback period of 5-6 years with 25-year system life.

Question 10

Can I use this calculator for commercial and industrial connections?

Accepted Answer

Yes, our calculator supports all GUVNL connection types including residential, commercial, industrial, and agricultural. For industrial connections, you can enter contract demand separately. The calculator automatically applies appropriate tariff rates, demand charges, and surcharges based on your selected connection category and consumption pattern.
