Overview
India's largest manufacturers are building their own power plants. ArcelorMittal just committed $900 million to 1 GW of solar and wind. Tata Steel locked in 379 MW through a group captive deal. UltraTech Cement plans to push its green energy mix from 22% to 85% by 2030. Across steel, cement, and aluminum, companies have installed 1.8 GW of renewable capacity since 2023 and announced plans for another 5+ GW.
The trigger is economics and existential threat. Captive solar delivers 30% cost savings versus grid power with 3-4 year payback periods. But the EU's carbon border tax adds €60-80 per tonne to high-emission steel exports starting 2026. India exports significant steel to Europe. Companies that don't decarbonize lose market access. So manufacturers are racing to build massive solar-wind-battery systems to power furnaces directly, bypassing utilities entirely.

Scenarios
Industrial Captive Renewables Hit 50 GW by 2030, Redefine India's Energy Mix
Discussed by: Ember, IEEFA, industry analysts tracking India's energy transition
If current momentum continues, Indian manufacturers could install 50+ GW of captive renewable capacity by 2030, fundamentally reshaping the country's power sector. This scenario assumes economics remain favorable with 3-4 year payback periods, government policies continue supporting open access and group captive models, and battery storage costs keep falling. Heavy industries would increasingly bypass utilities, building dedicated solar-wind-battery systems directly connected to factories. This would accelerate India's 500 GW renewable target while making manufacturing more competitive globally through lower energy costs and carbon emissions.
Grid Constraints and Policy Backlash Slow Buildout to 30 GW
Discussed by: Utility sector stakeholders and state electricity regulators
State utilities lose revenue as large industrial consumers defect to captive power. Some states respond by raising cross-subsidy charges or restricting open access permits. Transmission infrastructure struggles to handle distributed generation from industrial sites. Land acquisition delays solar projects in key states. These friction points slow but don't stop the transition, with captive renewables reaching 30 GW by 2030 instead of 50 GW. Industries still pursue renewable energy for carbon compliance but face higher costs and longer development timelines.
Green Hydrogen Breakthrough Transforms Heavy Industry by 2028
Discussed by: Ministry of Steel, WEF analysis of hydrogen pilot projects
Government green hydrogen pilots succeed beyond expectations, with costs dropping from $4-7/kg to below $2/kg by 2027 through domestic electrolyzer manufacturing and scale. Steel producers shift investment focus from renewable electricity to hydrogen-based direct reduced iron, which offers deeper decarbonization. ArcelorMittal, Tata Steel, and JSW accelerate hydrogen adoption after successful pilot demonstrations. By 2028, India has multiple commercial-scale green hydrogen steel plants operating, positioning the country as a global leader in zero-carbon heavy industry ahead of Europe.
EU Carbon Tax Triggers Trade Conflict, India Retreats on Climate Goals
Discussed by: Trade policy analysts, WTO dispute observers
Indian government escalates opposition to EU's CBAM at WTO, arguing it violates trade rules and discriminates against developing countries. India implements retaliatory measures on European imports. EU refuses to back down. Trade tensions force Indian manufacturers to choose between European market access and domestic political pressures against perceived climate colonialism. Some companies build separate low-carbon production lines for exports while maintaining coal-powered operations for domestic sales. Industrial renewable buildout continues but at slower pace focused on cost savings rather than carbon reduction.
Historical Context
China's Industrial Solar Boom (2015-2020)
2015-2020What Happened
Chinese manufacturers installed over 15 GW of rooftop and captive solar between 2015-2020 as costs plummeted and air pollution regulations tightened. Electronics, textile, and chemical companies led adoption, driven by electricity cost savings of 20-30% versus grid tariffs. Provincial governments offered subsidies and streamlined permitting for industrial solar.
Outcome
Short term: Captive solar became standard practice for energy-intensive Chinese manufacturers, reducing electricity costs and emissions
Long term: China's dominance in solar manufacturing accelerated as domestic demand surged; industrial users became testing ground for advanced technologies
Why It's Relevant
India follows similar trajectory but larger scale—targeting 50+ GW industrial renewables versus China's 15 GW, driven by carbon border taxes China didn't face
U.S. Steel Industry Collapse (1970s-1980s)
1970-1990What Happened
American steelmakers failed to modernize production technology while energy costs soared following oil shocks. Companies continued operating inefficient blast furnaces powered by expensive fossil fuels rather than investing in electric arc furnaces and energy efficiency. Japanese and Korean competitors with modern facilities captured global market share.
Outcome
Short term: Thousands of steel plants closed across the U.S. Rust Belt; employment dropped from 400,000 to 140,000 workers
Long term: U.S. lost position as global steel leader; industry never fully recovered despite later modernization efforts
Why It's Relevant
Indian manufacturers remember this lesson—companies that don't adapt to energy transition risk losing competitiveness permanently, especially with EU carbon border tax changing economics
Germany's Energiewende Industrial Impact (2010-2020)
2010-2020What Happened
Germany's aggressive renewable energy push drove electricity prices 50% above EU average by 2013. Energy-intensive industries—chemicals, steel, aluminum—received exemptions to prevent offshoring but still struggled with competitive disadvantage. Some companies relocated production to countries with cheaper power.
Outcome
Short term: Industrial electricity consumption declined 15%; Germany lost market share in energy-intensive exports
Long term: Policy adjustments provided relief but highlighted risk of poorly designed energy transitions hurting manufacturing competitiveness
Why It's Relevant
India's captive model avoids Germany's mistake by letting manufacturers control their own clean energy rather than depending on expensive grid-supplied renewables
