Tamil Nadu Faces Power Shortage as Electricity Costs Surge to ₹37 per Unit, Sparking Political Row

Tamil Nadu is facing mounting pressure on its electricity supply system as unusually hot October weather pushes demand higher and shortages force the state to purchase power at record prices. The emergency procurement plan, which includes electricity costing as much as ₹37 per unit, has triggered a political dispute over whether the crisis could have been prevented through better planning.

The state government says expensive short-term purchases are necessary to avoid prolonged power cuts. Opposition parties, however, have questioned the administration’s preparedness and raised concerns about the financial impact on the state’s electricity distribution utility.

Rising Demand and Supply Shortfalls

Tamil Nadu’s electricity demand has remained unusually high despite the arrival of October. State data showed evening peak demand reaching approximately 20,527 megawatts, while the Electricity Minister, C.T.R. Nirmal Kumar, said demand had climbed to around 21,700 MW.

At the same time, the state faced a shortfall in expected electricity supplies from central generating stations. Wind power generation also fell sharply, with output reported at about 500 MW against an expected 3,500 MW.

The combination of high consumption and lower-than-anticipated generation left the state seeking additional electricity through short-term market purchases.

The distribution utility arranged emergency procurement for the period from October 12 to October 31. The plan covers different time windows, including overnight demand and the evening peak, when household consumption and commercial activity place additional pressure on the grid.

Why Is Electricity Costing So Much?

The highest price in the procurement arrangement is ₹37 per unit, significantly above the rates available under many conventional electricity supply agreements.

Gas-based power plants are among the sources being used to address the shortage. Although they can provide flexible electricity when demand rises, their generation costs can be substantially higher than those of some other sources.

Under the arrangement, the utility can adjust how much electricity it actually draws according to demand. This flexibility may help limit expenditure if the state requires less power than anticipated.

The government has indicated that it expects to purchase around 1,500 MW of higher-cost electricity during evening peak periods, rather than necessarily drawing the full capacity covered by the tender.

The minister has estimated that emergency procurement could add approximately ₹5 crore to daily costs. He argues that the expense must be weighed against the possibility of power cuts lasting two to three hours.

DMK and AIADMK Question the Government

The procurement decision has become a major political issue, with both the DMK and AIADMK criticising the government’s handling of electricity supply.

Opposition leaders argue that the administration should have anticipated the demand increase and secured cheaper electricity in advance. They have also questioned why Tamil Nadu is paying substantially more than prices reported in some neighbouring states.

AIADMK general secretary Edappadi K. Palaniswami has demanded that the procurement decision be withdrawn, alleging serious mismanagement. DMK leaders have also questioned whether the shortage could have been avoided.

The government rejects allegations that the crisis was deliberately created or that cheaper existing agreements were arbitrarily cancelled. It maintains that the emergency purchases are intended to protect consumers from widespread interruptions.

The allegations of corruption and deliberate mismanagement remain political claims and have not been established as facts.

Long-Term Planning Becomes Central to the Debate

The controversy has renewed attention on Tamil Nadu’s longer-term electricity requirements. The government says it plans to invite tenders for additional long-term power purchase agreements and expand available generation capacity.

Officials are also examining ways to improve thermal power generation and strengthen renewable energy infrastructure, including battery storage. Energy storage could help make surplus solar electricity available later in the day, when demand remains high but solar generation declines.

Earlier regulatory warnings had highlighted the financial risks of depending heavily on expensive short-term electricity purchases.

What the Crisis Means for Consumers

The immediate priority is maintaining reliable electricity supplies while controlling procurement costs. Although the government says the emergency arrangement is temporary, sustained reliance on high-priced power could deepen the distribution utility’s financial burden.

Whether consumers eventually face higher costs will depend on the duration of the shortage, the amount of expensive electricity actually purchased and how the utility manages its finances.

Tamil Nadu’s current predicament highlights the importance of matching electricity demand with dependable generation and planning for weather-related fluctuations. The political dispute may continue, but the longer-term challenge remains ensuring affordable, reliable power without repeated emergency purchases.
