What happened
On 11 September 2026, Waaree Green Data Centers incorporated Sunstar Data Centers — and on 14 September added Aurovault — to build AI-ready hyperscale and edge data centres in India and abroad.
Waaree Renewable Technologies via Waaree Green Data Centers incorporated Sunstar Data Centers on 11 September 2026 and Aurovault Data Centers on 14 September 2026 to build AI-ready hyperscale and edge data centres in India and abroad.
Both units are newly incorporated with nil turnover and yet to start operations, and Waaree had disclosed no firm data-centre orders as of July 2026 despite a broad mandate spanning colocation, cloud infra and GPU hosting.
The push coincides with JLL's forecast of India DC capacity rising from 1.6 GW to 6 GW by 2029 and WRTL's view that AI facilities need 10x power of conventional sites, leveraging the group's solar + BESS + T&D stack after the 55% buy of Associated Power Structures.
Q1FY27 revenue grew 53% YoY to Rs 925 crore and profit 38% to Rs 120 crore on a 10 GWh BESS and Rs 20,000 crore T&D pipeline, but the wider Rs 31,500 crore Waaree Energies pipeline and 8.6x FY28E EV/Ebitda valuation keep capex discipline in focus.
Timeline — from EPC to AI infra
- June 2026 — WRTL acquires 55% in Associated Power Structures, adding T&D capabilities.
- Aug 2026 — Waaree Green Data Centers moved under Waaree Energies (holding co.) restructuring.
- 11 Sep 2026 — Sunstar Data Centers incorporated as step-down subsidiary for AI-ready DCs.
- 14 Sep 2026 — Aurovault Data Centers incorporated as second step-down DC subsidiary.
What to watch next
Incorporation is step zero. Real catalysts are land/power procurement, anchor tenant MoUs, and capex funding clarity on top of the existing Rs 31,500 cr pipeline. No approvals needed per filing, but execution bandwidth is the constraint.
What is confirmed vs unclear
Confirmed: incorporation dates, nil turnover, broad DC mandate, non-RPT cash subscription. Unclear: capex amount, location, power sourcing, first client and timeline to revenue.
Why it matters for me
Investors now price a broader capex story beyond EPC, balancing a 6 GW India DC runway against WRTL's Rs 31,500 crore pipeline and stretched execution bandwidth.

Investors · Traders
New data-centre subsidiaries add capex and execution risk on top of Rs 31,500 crore Waaree Energies pipeline — stock already down ~25% YoY at 8.6x FY28E EV/Ebitda.

Business Executives · Investors
If WRTL secures power, land and anchor tenants, AI-ready DCs could open a high-value annuity stream leveraging solar + BESS + T&D stack.
Daily Life
Business Executives
India's DC capacity set to grow 1.6 GW to 6 GW by 2029; 10x power needs for AI DCs put energy-efficient infra in focus for enterprises and consumers.
What to remember
Optionality is real, but track land, power and anchor client wins — not just incorporation headlines.
Waaree Renewable's AI-ready data centre push via Sunstar & Aurovault adds optionality — and execution risk — as India heads to 6 GW capacity.

7 claimsWaaree Renewable Technologies via Waaree Green Data Centers incorporated Sunstar Data Centers Private Limited on 11 September 2026, disclosed to exchanges on 12-13 September 2026.
Sunstar's mandate is to establish, develop, design, finance, construct, own, lease, operate and commercialise data centres including hyperscale, AI-ready, edge, disaster recovery, cloud infra, digital parks and colocation, plus managed hosting, GPU hosting and HPC services.
Sunstar is newly incorporated with nil turnover and yet to commence business operations, with no firm data-centre orders disclosed as of July 2026.
India's data-centre capacity is expected to grow from 1.6 GW in mid-2026 to 6 GW by 2029 per JLL, and WRTL estimates AI-driven facilities need at least 10x power vs conventional centres.
In Q1FY27, WRTL's bidding pipeline included 10+ GWh BESS and Rs 20,000 crore T&D opportunities; revenue Rs 925 crore (+53% YoY) and net profit Rs 120 crore (+38% YoY).
Waaree Green Data Centers incorporated a second step-down subsidiary Aurovault Data Centers on 14 September 2026 with the same data-centre mandate, per CNBC TV18.
Sunstar incorporation is not a related-party transaction, no promoter interest, no governmental approvals required, and consideration is cash subscription to MoA by Waaree Green Data Centers.
