Chennai: To ensure a reliable, round-the-clock power supply, meet the state’s projected peak demand growth, and renewable energy integration requirements, the Tamil Nadu Power Distribution Corporation Ltd (TNPDCL) is set to procure 270MW of green power through the Solar Energy Corporation of India (SECI) for 25 years.The cost of power would be between 5.06 and 5.07 a unit, and the supply is expected to start in two years. TNPDCL will also pay 7 paise a unit as a trader margin to SECI. As per the project, SECI will enter into a power purchase agreement (PPA) with private green power generators and supply to TNPDCL.TNPDCL (as erstwhile Tangedco) in 2024 signed deals with SECI to procure solar power for 500MW—200MW at the rate of 2.72 a unit and 300MW at the rate of 2.73 a unit—and the supply is yet to begin. Tangedco already bought 3,000MW from SECI. TNERC approved TNPDCL’s power procurement plan with SECI, stating that it aligns with both state and central govts’ aim to increase the installed capacity of non-fossil fuel energy sources to 50% of overall capacity by 2030. TNPDCL chairman J Radhakrishnan said the remaining tenders will be finalised when firms offer power at a favourable price. “We have 2,198 MW of medium-term power available this year, unlike previous year. The 800 MW Stage III NCTPS plant also started generation. While they are an advantage, we may have to buy short-term power to be on the safer side,” said the official.
