The Tamil Nadu Generation and Distribution Company (Tangedco) fixed the tariffs for solar power at INR 4.40 for each unit on Sat. Through this, the costs dropped from INR 7.10 to INR 4.40 within twelve months.
The electricity distributor of the state Tangedco opened the bids initially for 300 Megawatts of solar power and to be set-up in the year 2017-18. The tariff fixed by Tangedco was INR 4.50, and the bid for 100 Megawatt came to be around INR 4.40 for a single unit.
The officials at Tangedco said, “This is the lowest bid out of 22 proposals which we received for 300MW. There are other bids at INR 4.48 or higher, but they will have to reduce their bids and match the lowest tariff of INR 4.40.”
The TNERC (Tamil Nadu Electricity Regulatory Commission) allowed Tangedco to set up photovoltaic projects for a maximum capacity of only 500 MW for the coming fiscal year. Out of this 500 MW, Tangedco instilled bids for 300 MW. During the month of Nov last year, Tangedco received some 20 bids for 116 Megawatts of energy. Now, with all the bids, Tangedco has overall 416 Megawatts out of 500 Megawatts.
The lowest price obtained so far for a single unit of solar power is INR 4.34 in Rajasthan. The reverse e-auction tender conducted by the state of Rajasthan enabled the tariff to drop down. Solar power is even cheaper than coal. The country’s Energy Minister, Piyush Goyal revealed that the low tariffs would help India achieve their dream of producing 100 Gigawatts of energy by the year 2023.
In the Rewa city of Madhya Pradesh, they received a bid of a small tariff of INR 3.3 per kWh, setting a record in the solar-based tariff. The solar power is said to come down even more and soon level with the tariffs of conventional energy. With advancements in technology and increased efficiency, the solar power sector is deemed to boom even further in coming days.
Although the solar tariff is much less in other states when compared with Tamil Nadu, the extreme land prices inhibit the solar tariff to go further down. An official of solar manufacturers of Tamil Nadu said, “In Tamil Nadu, the land price is exorbitant. Most of the capital cost is invested in the land. Once we say that the ground is for the solar power project, the price is jacked up further.”
