Regen Powertech

What Regen Powertech does

Regen Powertech Pvt Ltd is an Indian renewable energy equipment manufacturer headquartered in Chennai, Tamil Nadu, founded in 2006 (manufacturing operations commenced in 2008 at Tada, Andhra Pradesh). The company designs, manufactures and supplies multi-megawatt gearless direct-drive Permanent Magnet Generator (PMG) wind turbines — primarily under a license from Germany's Vensys Energy AG — across the 1.5 MW Vensys 77/82/87/89 platform and its own proprietary 2.8 MW and 3.0 MW wd-class turbines. It provides full turnkey wind power project solutions covering manufacturing, supply, erection, commissioning and long-term operations and maintenance, alongside an in-house SCADA system and water-cooled central solar inverters (1 MW / 1.5 MW / 2.0 MW). It also pioneered MW-scale wind-solar hybrid systems integrating both generation sources at the inverter level, and operates a transformer products and rental business.

Manufacturing is conducted at two fully integrated ISO 9001/14001/50001 and OHSAS 18001 certified facilities — Tada in Andhra Pradesh (capacity scaled from 25 MW to 750 MW per annum) and Udaipur in Rajasthan (30 MW to 300 MW per annum) — with an additional office in Mumbai and New Delhi for sales coverage. The company claims the largest market share among Indian Independent Power Producers (IPPs) and had reached a cumulative installed base of over 1.8 GW across India and Sri Lanka by October 2015, with named enterprise customers including SembCorp Green Infra, ReNew Power, Greenko, Hero Future Energies, Bhilwara Energy and Malpani Group, as well as corporate energy buyers from textiles (RSPL/Ghari, Sulochana Cotton Mills, Royal Classic Mills) and other sectors.

ReGen is privately held and was historically PE/VC-backed (a 2012 funding round drew IDFC Private Equity, Mac Fund and TVS Capital Funds). Since 9 December 2019 the operating company has been in Corporate Insolvency Resolution Process under NCLT; the NCLT-approved February 2022 resolution plan was set aside by NCLAT in August 2023, the CIRP was re-run by NCLT in April 2026 and that re-run was stayed by NCLAT in May 2026. The firm nonetheless continues to publish news, take orders and file audited financials through FY 2024-25, indicating ongoing operations under interim resolution-professional oversight rather than liquidation.
