Adequate, reliable power is the lifeblood of any manufacturing operation. In Tamil Nadu, industrial power is supplied by TANGEDCO (Tamil Nadu Generation and Distribution Corporation). Understanding the types of connections available, the tariff implications, and the application process will help you plan your factory setup more effectively.
All industrial power in Tamil Nadu falls into two broad categories based on the connected load:
For most small factories up to about 100–150 HP of machinery, LT supply is adequate and involves lower upfront costs. Moving to HT is necessary for larger operations but adds ₹10–30 lakhs in substation equipment costs.
TANGEDCO classifies LT consumers into several categories. Industrial units typically fall under:
The higher the load category, the higher the fixed demand charge per month (charged regardless of consumption) and the per-unit energy charge. Always match your sanctioned connected load to your actual machinery needs — over-sanctioning means higher fixed charges, while under-sanctioning leads to overload tripping and potential penalties.
LTCT stands for Low Tension Current Transformer metering. For industrial loads above 75 HP (approximately 55 kW), TANGEDCO requires CT-operated (current transformer) meters rather than direct meters. This is because direct meters cannot safely handle the high currents involved.
LTCT meters measure actual consumption more accurately and are also used for demand measurement (recording peak power demand, which is billed separately). At Vedanth Industrial Zone, LTCT power is available at the site, making it suitable for medium-scale industrial operations without requiring HT conversion.
The process for a new industrial LT connection from TANGEDCO involves:
Timeline: 2–6 months depending on the load and distance from the nearest feeder.
For factories located near existing HD power transmission lines (like those at Vedanth Industrial Zone), TANGEDCO can typically provide a new connection faster since the main line infrastructure is already in proximity.
Industrial units in Tamil Nadu are billed on both energy consumed (kWh) and maximum demand (kVA). Poor power factor increases your kVA demand without increasing useful work output — leading to higher bills. Always install automatic power factor correction (APFC) panels to maintain power factor above 0.90. TANGEDCO offers incentives for units maintaining high power factor.
Our site near Annur, Coimbatore has HD power transmission lines directly overhead and LTCT metering available — making new industrial connections faster to establish. This infrastructure advantage translates to less waiting time and lower connection costs compared to remote rural industrial sites.
Vedanth Industrial Zone offers Red Zone land and factory buildings for rent near Annur, Coimbatore. Competitive rates, flexible leases.
