- Techno Electric & Engineering Company began building power stations when India’s grid was still taking shape - it wired NTPC’s very first plant - and over six decades it has quietly constructed more than half of PGCIL’s substations. Today it is a zero-debt, cash-rich infrastructure house that uses the steady profits of its high-voltage electrical contracting to build long-term annuity assets in digital infrastructure: data centres and smart meters. The recurring pattern is simple - win technically difficult work that few others can bid for, execute it without penalties, and then recycle the cash into owning and operating assets that pay out for decades.
Business segments
Three engines at different stages - a high-voltage EPC cash cow, a national digital-infrastructure platform under construction, and a smart-metering annuity book - each funded by the cash flows of the one before.
1. EPC: building the hardest parts of India’s power grid
The company wins complex, high-voltage substation and power-plant contracts that carry technical barriers to entry, delivering them on time and without penalties - that is how it earns margins roughly twice the industry norm.
- Only the difficult work - it focuses on Extra High Voltage (EHV) substations of 765 kV and 400 kV, the most technically demanding segments, and deliberately avoids low-margin transmission-line jobs where competition is fierce. It has built over 50% of Power Grid Corporation’s substations - 160 out of 276 - and has been involved in nearly every NTPC power-station installation.
- Margins protected by know-how - the EPC business consistently delivers EBITDA margins of 13-15%, while industry peers struggle in single digits, because the EHV segment’s technical complexity keeps out casual bidders. The business has a Return on Capital Employed of 64.1% as of March 2025.
- Forty-year supply relationships - long-standing ties with global OEMs such as Schneider, Vertiv, GE and Siemens give it supply-chain advantages over new entrants who cannot replicate those procurement terms quickly.
- Zero-penalty track record - across more than 500 projects since inception, it has never paid a penalty for late or faulty delivery, which makes it a preferred bidder for repeat clients; 70% of orders in the past three years came from customers who came back. It once delivered a 765/400 kV, 3 GW substation at Sikar in just nine months, a national record.
- A deep order book - as of December 2025 the EPC order book stood at INR 10,200 crores, with roughly INR 2,500 crores in new confirmed orders secured between April 2025 and February 2026, plus another INR 750 crores where it is the lowest bidder. The largest client, Power Grid Corporation, accounts for 21-22% of the book, but the company is actively diluting concentration as data-centre and smart-metering verticals scale up.
2. Data centres: a national digital-infrastructure platform under construction
The company is building and owning a network of hyperscale and edge data centres across India, using its in-house electrical-engineering muscle to construct them faster and cheaper than pure-play operators can.
- Built, not just bought - because 70% of data-centre capital expenditure is electromechanical work, the company’s 40-year EPC capability saves up to 18% in construction costs and compresses deployment to 18 months versus the industry’s 24-36 months. It runs seven simultaneous projects across emerging hubs rather than building sequentially, which speeds up market capture.
- Edge network riding national fibre - through a 20-year exclusive revenue-sharing partnership with RailTel, a government-owned enterprise with 61,000+ km of fibre, the company is deploying over 100 edge data centres across 23 states. The first facility in Gurugram is already live and fully occupied; Mumbai goes live shortly after, and locations in Indore, Bhubaneswar, Ahmedabad and Lucknow are next.
- Selling services, not just space - in edge facilities the company uses about 60% of capacity itself and monetises the rest by selling managed cloud services, not merely colocation; it has already onboarded its first cloud customer. It targets INR 100 crores-plus in edge revenue for FY27, with 50-60% EBITDA margins - nearly four times EPC margins.
- Green power built in - the Chennai data centre was chosen partly because the company already owns renewable-energy assets in Tamil Nadu that can supply it, and the facility runs at a Power Usage Effectiveness of roughly 1.35 with 75% lower water use than conventional designs. Energy cost is a pass-through to the customer, so the revenue per MW - INR 8-10 crore per annum - excludes power.
3. Smart metering: a long-dated annuity book from the government’s grid upgrade
The company installs and operates smart meters under decade-long contracts where it earns a fee per meter per month, creating a steady income stream that smooths out the lumpiness of EPC.
- Paid per meter, per month - revenue is recognised only after each meter is commissioned with its communication module and software, and then it flows monthly for the 93-month operations-and-maintenance phase that follows the 27-month installation window.
- A 2.24-million-meter order book - the company holds four AMI projects across Madhya Pradesh, Jammu & Kashmir, Jharkhand and Tripura, worth INR 2,612 crores under the government’s Revamped Distribution Sector Scheme. As of December 2025, roughly half the order book had been executed, with the Indore facility targeted for completion by March end and Ranchi projects by June '26 and the rest by December 2026.
- Profit over volume - the company is seeing margin pressure in some new tenders and has turned selective, bidding only where returns make sense, and it has taken no debt to fund the AMI rollout.
Group structure and partners
The listed parent holds the EPC business directly, while each new infrastructure vertical - data centres, smart meters, transmission assets - sits in its own wholly-owned subsidiary, keeping the balance sheet clean and the cash flows ring-fenced.
- The core EPC business resides in the standalone parent company, Techno Electric & Engineering Company Ltd.
- The data-centre business is housed under Techno Digital Infra Private Limited and related entities, while the smart-metering business operates through a series of five AMI Solutions SPVs.
- TBCB transmission projects are held in NERES XVI Power Transmission Limited and NERGS-I Power Transmission Limited, both acquired in 2024.
- The 20-year exclusive edge-data-centre concession is with RailTel Corporation of India, a government Navratna CPSE that provides access to its 61,000+ km national fibre network.
- The company has 40-year supply relationships with global OEMs - Schneider, Vertiv, GE and Siemens - and has previously partnered with firms from China, South Korea and Canada to jointly deliver US$500 million worth of projects.
