JSW Energy commissions 300 MW SECI-X wind in 2024

What JSW Energy announced

JSW Energy said its step-down subsidiary, JSW Renew Energy Two Limited, has completed the commissioning of 300 MW of wind power capacity at Tuticorin, Tamil Nadu. The capacity is part of an ISTS-connected wind power project awarded under Solar Energy Corporation of India (SECI) Tranche X. The company disclosed the development through a stock exchange filing and a press release dated September 15, 2024. JSW Energy described this milestone as its first greenfield wind power plant commissioned for SECI. The company also linked the development to its broader renewable energy expansion plans.

Project structure: Tuticorin and Dharapuram

The SECI Tranche X wind project is described in the company material as a 450 MW ISTS-connected wind power project spread across Tamil Nadu. JSW Energy said 300 MW has been commissioned at Tuticorin. It also stated that the additional capacity at Dharapuram is nearing completion, with 138 MW already commissioned there. That makes at least 438 MW commissioned across the two locations, based on the figures cited in the press release.

Separately, the provided note also mentions: “Currently 518 MW is commissioned across Tuticorin and Dharapuram region.” And another section describes “SECI X (454 MW)” as fully commissioned in FY2025, split as 302 MW in Tuticorin and 152 MW in Dharapuram. These disclosures present different totals for the same SECI-X label in the material provided. JSW Energy’s exchange filing and press release specifically highlight the 300 MW commissioning at Tuticorin and 138 MW commissioned at Dharapuram, along with an overall SECI-X project size of 450 MW.

Why the commissioning matters for JSW Energy

JSW Energy positioned the commissioning as a marker of execution capability, as it brings a greenfield wind project online under a central government-backed procurement programme. The company also underlined that the project is backed by a 25-year Power Purchase Agreement (PPA) with SECI, which it said supports stable cash flows over the contract period. The commissioning announcement is also relevant because it changes the company’s reported operational scale. After this commissioning, JSW Energy said its total installed capacity stands at 7,726 MW.

Updated capacity numbers shared by the company

Following the commissioning of the 300 MW phase, JSW Energy disclosed updated portfolio figures. The company said its under-construction capacity stands at 2,114 MW, which is expected to be commissioned by the end of FY2025. It also disclosed that its current installed wind capacity stands at 2,152 MW. These figures were reiterated across the filing and the market report included in the text.

Management comment in the filing

In the provided material, Sharad Mahendra, Joint Managing Director and CEO of JSW Energy, is cited as saying the company has commissioned its first greenfield wind power plant for SECI. The statement frames the commissioning as a reaffirmation of execution capability and the company’s emphasis on expanding renewable capacity. The filing and release do not provide tariff details, capex, or project cost, but they do specify the project is ISTS-connected and tied to SECI under a long-term offtake arrangement.

Stock market reaction: shares hit a life high

JSW Energy shares rose to a record high after the commissioning update. According to the provided market report, the stock rose as much as 1.56% to Rs 780.30 per share, described as the highest level since its listing on Jan 1, 2010. At 09:38 a.m., the stock was trading 0.49% higher at Rs 772 per share. Over the same time window, the NSE Nifty 50 index was up 0.23%.

Project progress: phase-wise commissioning and earlier milestones

The material also notes that JSW Renew Energy Two had started phase-wise commissioning of the SECI-X project earlier, with the first phase commissioning of 27 MW. It said this initial step was ahead of schedule and part of progressive commissioning of the greenfield 450 MW wind project. In the September 15, 2024 release, JSW Energy also said the remaining capacity at Dharapuram was nearing completion, and that 138 MW had already been commissioned there.

Pipeline disclosures: SECI-linked wind and fresh LoA

Beyond SECI Tranche X, the text includes a pipeline snapshot. It says around 2.63 GW of renewable energy projects are currently under construction or in the pipeline. Within this, it references wind projects of 1.26 GW tied with SECI, expected to be fully commissioned in the next 12-18 months. It also says the company has received a Letter of Award (LoA) for a 300 MW wind project from SECI under its Tranche XII auction.

Market impact and what to watch next

The immediate market impact, based on the provided report, was a move to a fresh record high in JSW Energy shares alongside modest broader index gains. Operationally, the commissioning adds to the company’s renewable portfolio and advances SECI-linked capacity that has long-term offtake coverage through a 25-year PPA.
