JSW Energy commissions 51 MW SECI-IX wind phase in Tamil Nadu

What JSW Energy announced

JSW Renew Energy Ltd, a wholly owned step-down subsidiary of JSW Energy, has begun phase-wise commissioning of an 810 MW ISTS-connected wind power project in Tamil Nadu awarded under SECI tranche IX. The company said the first commissioned phase is 51 MW. The project is backed by a 25-year power purchase agreement (PPA) with the Solar Energy Corporation of India (SECI).

The commissioning update matters because it marks the start of deliveries from what JSW Energy described as its first and largest greenfield wind capacity bagged by the company under SECI-IX. The announcement also came with an updated snapshot of the group’s installed and under-construction generation capacity.

SECI tranche IX project: size, connectivity, and commissioning approach

The 810 MW project is connected to the Inter State Transmission System (ISTS), which enables power evacuation beyond a single state and is typical for large renewable awards under SECI tenders. JSW Renew Energy said the commissioning will happen in phases, beginning with 51 MW already commissioned.

The company did not provide a date-wise schedule for each phase in the provided statement, but it did say the remaining capacity would be commissioned in phases. The PPA tenure of 25 years with SECI provides a long-term offtake framework for the project.

Management commentary and near-term capacity target

Prashant Jain, Joint Managing Director and CEO of JSW Energy, said the company has started commissioning the SECI-IX wind project and called it the first and largest greenfield wind capacity bagged by the company. He added that the company is well placed to achieve a targeted 10 GW generation capacity by the end of CY2024.

In a separate update referenced in the provided material, Sharad Mahendra, Joint Managing Director and CEO, also linked the company’s greenfield wind commissioning milestone to the 10 GW installed capacity target by FY2025. Both statements underscore that management is tracking progress against a 10 GW milestone, albeit with different timelines cited across updates.

Installed capacity and under-construction pipeline after SECI-IX phase 1

Alongside the 51 MW commissioning, JSW Renew Energy said the total current installed capacity increased to 6,822 MW, while under-construction capacity stood at 2,969 MW, likely to be commissioned in phases over the next 12 months.

A separate line in the provided material described current installed capacity as 6,821 MW with the same under-construction figure of 2,969 MW. The company communication in the supplied text therefore reflects two closely reported installed capacity numbers around this update, while the under-construction pipeline remained consistent at 2,969 MW.

SECI tranche X update: 300 MW commissioned at Tuticorin

JSW Energy later informed exchanges that another step-down subsidiary, JSW Renew Energy Two Ltd, completed commissioning of a 300 MW ISTS-connected wind power project awarded by SECI under tranche X and located at Tuticorin, Tamil Nadu. The company described this as its first-ever greenfield wind power plant commissioned for SECI.

The same exchange filing and related reports in the provided text also noted that an additional 150 MW of wind capacity awarded under SECI tranche X at Dharapuram, Tamil Nadu was nearing completion, with 138 MW already commissioned.

Updated capacity figures after the tranche X commissioning

Following the 300 MW commissioning announcement, the company reported total current installed capacity of 7,726 MW and under-construction capacity of 2,114 MW. It said the under-construction capacity is expected to be commissioned by the end of FY2025.

The company also disclosed that its current installed wind capacity stands at 2,152 MW. In addition, it reported total locked-in generation capacity, including wind, solar, hydro, and thermal plants, of 18.2 GW, and a renewable pipeline of 8.3 GW, of which 2.3 GW have signed PPAs.

What the disclosures imply for JSW Energy’s renewable buildout

Across the SECI-IX and SECI-X updates, the company has highlighted two separate wind project streams in Tamil Nadu that are ISTS-connected and tied to SECI offtake structures. The tranche IX project is 810 MW with commissioning underway, while tranche X includes at least 300 MW commissioned at Tuticorin and progress reported for the additional 150 MW award at Dharapuram with 138 MW commissioned.

The combination of phased commissioning and disclosed under-construction capacity indicates a buildout plan that is being measured against stated capacity targets, including 10 GW, and longer-term goals referenced in the provided text such as 20 GW before 2030.

Key facts at a glance

Longer-term targets and storage additions mentioned

The supplied material also referenced JSW Energy’s targets to reach 20 GW generation capacity and 40 GWh of energy storage capacity by 2030. It further said the company has locked in 3.4 GWh of energy storage capacity through a battery energy storage system and a hydro-pumped storage project.

Separately, the text stated that with a total capacity of 9.8 GW, the company is well placed to achieve its near-term target of 10 GW by 2025. These disclosures frame the wind project commissioning updates within a broader expansion plan spanning renewable generation and storage.

Conclusion

JSW Energy’s recent disclosures show phased commissioning has started for the 810 MW SECI tranche IX wind project in Tamil Nadu with 51 MW commissioned, and that a separate SECI tranche X wind project has seen 300 MW commissioned at Tuticorin with additional capacity at Dharapuram nearing completion. The company has paired these updates with installed and under-construction capacity figures and reiterated its 10 GW milestone, while pointing to a wider renewable and storage pipeline with commissioning expected to continue in phases over the stated timelines.
