TNPDCL Summer Power Purchase 2027: Electricity Rates Fixed at ₹9.50 - ₹13

The Tamil Nadu Power Distribution Corporation Limited (TNPDCL) has decided to procure short-term electricity for the January to June 2027 period at rates ranging from ₹9.50 to ₹13 per unit. The decision comes as Tamil Nadu prepares to meet rising electricity demand during the summer months.

Electricity Resources Minister R Nirmalkumar announced the results of the fifth short-term power procurement tender on Friday. He said TNPDCL would purchase electricity at the lowest quoted rates available for each month.

The latest procurement plan aims to strengthen the state`s power supply during a period when electricity consumption and peak demand are expected to increase significantly.

TNPDCL Short-Term Power Purchase Rates for 2027

TNPDCL floated the latest tender on November 1, inviting bids for round-the-clock (RTC) electricity supply between January 18 and June 15, 2027.

The tender attracted offers ranging from ₹9.50 to ₹20 per unit. After evaluating the bids, the utility selected the lowest available rates for each month.

The approved power procurement rates are:

February recorded the lowest procurement rate at ₹9.50 per unit, while January and June recorded the highest selected rate of ₹13 per unit.

Power Supply Offers Fall Short of TNPDCL Requirements

Despite receiving bids from electricity generators, the total power offered was significantly lower than TNPDCL`s requirements.

For the second half of January, the utility received offers for only 81 MW against its requirement of 2,000 MW, meeting just 4.1% of the demand.

February recorded the highest response, with 1,381 MW offered against 3,000 MW sought, covering 46% of the requirement.

The response for other months was also belolow expectations:

March: 42.8% of the requirement was met.

April: 37.7% of the requirement was met.

May: 36.8% of the requirement was met.

First half of June: Only 181 MW was offered against 2,500 MW sought, meeting 7.2% of the requirement.

Tamil Nadu`s Summer Power Deficit Expected to Increase

The shortage in power procurement comes at a time when Tamil Nadu is expected to face a significant electricity deficit during the summer of 2027.

According to projections, the state`s evening peak power deficit is expected to increase from 1,388 MW in January to 5,544 MW in April 2027.

The projected deficit stands at 3,987 MW in May and 4,796 MW in June. These figures highlight the growing challenge for TNPDCL in securing sufficient electricity to meet the state`s demand.
