- You may be underestimating the next megatrend in steel and batteries.
- HEG controls a 3,000°C moat that fuels the fast‑growing electric‑arc‑furnace market.
- Its demerged greentech arm adds a $5‑billion revenue runway by 2030.
- Volume growth alone doubled earnings in the last nine months.
- Key risks: steel demand cycles, hydrogen‑based steel, and Chinese competition.
You missed the fine print on graphite electrodes and the green‑steel boom—now is the time to act.
Why HEG's Graphite Electrode Dominance Aligns with the Global Green Steel Surge
The steel sector contributes roughly 8% of worldwide CO₂ emissions, largely because traditional blast‑furnace‑basic‑oxygen‑furnace (BF‑BOF) plants spew about 2.33 tonnes of CO₂ per tonne of steel. Governments are tightening carbon‑tax regimes to meet Paris Agreement targets, prompting a rapid shift to electric‑arc‑furnace (EAF) technology. EAFs melt scrap steel using ultra‑high‑power (UHP) graphite electrodes that can reach 3,000 °C, delivering up to four times less carbon per tonne of steel.
From 2015 to 2024, the share of EAF‑produced steel in the West rose from 44% to 51%, and the trend is accelerating. HEG sits at the heart of this transition. As the world’s largest single‑site graphite electrode maker, it supplies 70‑75% of its output as UHP electrodes—exactly what EAFs need. For every million tonnes of steel melted in an EAF, 1,500‑2,000 tonnes of graphite electrodes are consumed. By 2030, the industry expects roughly 110 million tonnes of new EAF capacity (excluding China), translating into an additional 190,000‑200,000 tonnes of global electrode demand.
How the EAF Transition Reshapes the Steel Value Chain and Boosts HEG
HEG’s competitive edge stems from three hard‑to‑replicate factors:
- Scale: 100,000 TPA under one roof, with a planned expansion to 115,000 TPA by early 2028.
- Technical Moat: Graphitisation cycles last 5‑6 months per batch, requiring precise temperature control and high‑purity needle coke.
- Supply Flexibility: Short‑term contracts for petroleum‑based needle coke let HEG hedge price volatility.
These pillars enable HEG to operate at an 89% capacity utilisation— the highest among global graphite producers—driving the lowest per‑tonne cost structure in the sector.
HEG Greentech: The Four‑Pillar Play That Funds Its Ambitious Growth
HEG is not relying solely on electrodes. A strategic demerger will split the business into:
- HEG Graphite: The pure‑play graphite electrode company (future “HEG Ltd”).
- HEG Greentech: A clean‑tech platform housing four verticals—TACC (synthetic‑graphite anodes), REPlus (battery‑energy‑storage solutions), renewable IPP (solar‑plus‑BESS), and hydro power.
TACC leverages HEG’s graphitisation know‑how to produce synthetic graphite anodes for lithium‑ion cells. A 20,000 TPA greenfield plant near Indore will start in April 2027, with a long‑term goal of 60,000 TPA by FY32. Early pilot output already supplies 20+ cell manufacturers, and R&D is targeting silicon‑doped and graphene‑based anodes that could lift energy density by 30%‑40%.
REPlus offers end‑to‑end battery‑energy‑storage systems, currently at 1 GWh of cell‑to‑pack capacity. The target is 6 GWh by Q2 FY27, which could generate roughly ₹6,000 crore of revenue at projected EBITDA margins of 20‑25%.
Renewable IPP & Hybrid Solar‑BESS aims for a 2.3 GWp solar portfolio and 5.9 GWh BESS by FY30. The “build‑and‑flip” model—construct‑operate‑sell within 12 months—targets an IRR of 16‑20% while preserving capital for other growth arms.
Hydro Power provides the financial backbone. HEG fully owns the 86 MW Malana and 192 MW AD Hydro plants in Himachal Pradesh, delivering >80% EBITDA margins and >₹300 crore free cash flow annually. A pending 76 MW acquisition in Uttarakhand will deepen this cash engine.
Financial Snapshot: 20% Volume Growth Doubles HEG's Bottom Line
In the nine months to FY26, HEG’s revenue jumped 21.6% to ₹1,965 crore, driven entirely by a 20% lift in electrode volumes—pricing remained flat. EBITDA surged 58.5% to ₹623 crore, with margins expanding 740 bps to 31.7%. Net profit more than doubled to ₹344 crore, reflecting the highest utilisation rate in the industry.
These results validate the “volume‑first” thesis: as EAF adoption accelerates, electrode demand will scale faster than price, allowing HEG to capture incremental earnings without commodity‑price risk.
Investor Playbook: Bull vs. Bear Cases for HEG
Bull Case
- Continued global carbon‑tax pressure forces steelmakers to convert legacy BF‑BOF plants to EAFs, expanding electrode demand beyond the projected 190‑200 kt by 2030.
- Successful demerger unlocks a clean‑tech valuation premium; HEG Greentech could achieve ₹5,000 crore revenue and 20‑25% EBITDA margin by FY30.
- Hydro cash flow funds capex without diluting shareholders, supporting a sustainable 30:70 equity‑to‑debt financing mix.
- Strategic TACC rollout captures a growing share of the synthetic‑graphite anode market, which today accounts for ~85% of lithium‑ion demand.
Bear Case
- Steel demand slowdown or a rapid shift to hydrogen‑based steelmaking could reduce EAF‑driven electrode consumption.
- Chinese manufacturers adding 200 kt of UHP capacity could pressure global pricing and erode HEG’s cost advantage.
- Volatility in lithium‑ion cell prices and a potential pivot to sodium‑ion or solid‑state batteries may curtail TACC’s upside.
- GrafTech investment loss signals exposure to US‑based competitors struggling with high production costs.
At a current EV/EBITDA of 16.5×—near the 10‑year median of 18× and below peers like Graphite India (25.6×)—HEG trades at a modest discount, leaving room for re‑rating if the growth narrative materialises.
