Chennai: After repeated attempts to secure low-cost power through short-term tenders failed, Tamil Nadu Power Distribution Corporation (TNPDCL) plans to invite bids only from coal-based plants for round-the-clock supply to bridge the state’s power deficit until July 2027.The last three tenders drew the lowest quotes of 37, 41.50 and 35 per unit from gas-based plants, and TNPDCL faced criticism for failing to secure cheaper power. Electricity and law minister C T R Nirmal Kumar said the contracts were not signed because the quoted prices were too high.The state’s power demand is expected to cross 23,000MW in summer of 2027, with the deficit estimated at 3,000MW to 7,500MW.TNPDCL officials told TOI that cheaper power was available in the third tender, but the bidders insisted that the utility also buy higher-priced power as part of the deal.“In subsequent tenders, we will invite bids from coal-based power plants for round-the-clock supply,” an official said.Officials said coal-based power would be substantially cheaper than gas-based electricity, though it would have to be purchased for all 24 hours.“With demand expected to be high, we can opt for round-the-clock supply,” the official further said.
