The state of the sector, in plain English
India is in the middle of a demand-led power upcycle, and for once nearly every part of the chain is moving at the same time. Electricity demand keeps setting records — peak demand hit 270.8 GW in May 2026 — and the country is meeting it with almost no deficit. To keep up, India is doing two things that sound contradictory: building renewables at a furious pace (non-fossil capacity has crossed 50% of the ~533 GW installed base, about five years ahead of schedule) and sanctioning a fresh wave of coal plants (~80 GW in the pipeline) to cover the evening peak when the sun is down. Underneath that, a transmission super-cycle worth over ₹9 lakh crore is being built to move clean power from the deserts of Rajasthan and Gujarat to where people actually live, and the lenders who fund all of it are having a boom.
The genuinely new thing is that the sector’s chronic weak link — the distribution companies that sell power to your home and have lost money for decades — turned a collective profit in FY25 for the first time in over ten years, and the dues they owed generators collapsed from ₹1.4 lakh crore to under ₹5,000 crore. That doesn’t mean the discoms are fixed, but it means the cash is, for now, flowing through the system instead of clogging in the middle. The risks are real and specific: renewables are being switched off (~300 GWh curtailed in Q1 2026) because the wires aren’t ready; a regulatory change called “market coupling” could hollow out the power exchange’s business; coal faces a long-term transition clock; and several of the fashionable growth names are priced for a future that has to arrive on time.
The value chain, mapped
Electrons flow left to right; money flows right to left — the consumer’s bill, collected by the discom, pays everyone upstream. The discom is both the cash register and the historical bottleneck.
Fuel → Generation → Transmission → Distribution → Consumer, with Equipment & EPC supplying the whole chain, Financing (PFC/REC/IREDA) funding it, and Markets & institutions (IEX, Grid-India, the regulators) setting the rules.
- Fuel / upstream. Coal India is a near-monopoly that still feeds ~70% of generation; it missed its FY26 volume target and faces a slow transition question, but throws off enormous cash. Gas is a small swing fuel.
- Generation. NTPC anchors the sector (~89 GW, pivoting into renewables and now nuclear); Adani Power is the largest private coal fleet; JSW Energy is racing from thermal into storage; hydro (NHPC, SJVN) is slow and low-return in its build phase. The SHANTI Act (Dec 2025) opened nuclear to private players for the first time.
- Transmission. Power Grid Corporation is the regulated backbone (~85% of inter-state lines), now inflecting from annuity to growth as the RE-evacuation build ramps; Adani Energy Solutions leads the private TBCB pipeline.
- Distribution. Mostly loss-making state discoms, being reformed via the ₹3 lakh-crore RDSS scheme and smart metering. The well-run exceptions are private/integrated: Torrent Power, CESC, Tata Power and Adani Electricity.
- Equipment & EPC. The picks-and-shovels, riding an order-book super-cycle: BHEL (record ₹2.4 lakh-cr backlog), transformers and cables (Polycab, KEI, Apar), Suzlon Energy in wind, and Waaree Energies in solar modules.
- Financing. Power Finance Corporation, REC and IREDA — quasi-sovereign lenders funding the capex wave. PFC and REC are in the middle of a merger (Presidential approval came in June 2026).
- Markets. IEX dominates the power exchange (record May-2026 volumes) but faces a market-coupling overhang that could erode its moat.

Tailwinds & headwinds
Tailwinds
- Structural demand growth — AC penetration, EVs, data centres, manufacturing; CEA projects ~1,121 GW capacity by FY36 (from ~533 GW now).
- A multi-year capex super-cycle across generation, a >₹9 lakh-crore transmission build, and equipment order books.
- Discom finances mending (first FY25 profit in a decade; genco dues down to ~₹4,927 cr) — cash is flowing again.
- Policy push: 500 GW non-fossil by 2030, RDSS, PM Surya Ghar, solar/battery PLI, ALMM import substitution.
- Collapsing storage costs (BESS tenders ~$0.068/kWh) making renewables dispatchable.
Headwinds
- RE curtailment — ~300 GWh switched off in Q1 2026 because transmission lags generation; land and right-of-way delays.
- Market coupling — CERC’s proposed change threatens IEX’s price-discovery business.
- Soft thermal PLF (~65%) and a long-term transition clock over coal.
- Tariff compression in RE auctions; financing-cost sensitivity for developers.
- Rich valuations in pockets — several growth names price in years of flawless execution.
- Discom reform is real but unfinished; AT&C losses still ~15%.
Policy & regulatory landscape
The rules are set by the Ministry of Power (the grid, discoms, thermal), MNRE (renewables), CEA (planning), and CERC + state SERCs (tariffs). The live items that move companies:
- RDSS — ₹3 lakh-cr reform-linked discom scheme; ₹2.83 lakh-cr invested, driving smart metering.
- PM Surya Ghar — rooftop solar subsidy; ~9.57 GW installed since Feb 2024.
- PLI — solar cells/modules and batteries; the solar PLI is working (import substitution), the battery PLI is badly behind (~2.8% of target).
- ALMM List-II + DCR (live 1 June 2026) — forces Indian-made solar cells in most project categories; a wall around domestic OEMs.
- Market coupling — CERC’s draft to pool exchange bids for a single clearing price; the key risk to IEX.
- SHANTI Act (Dec 2025) — opens nuclear build/operate to private players, ending NPCIL’s monopoly.
- FGD norms — emission-control retrofits for thermal plants; a capex tailwind for equipment makers.
- The 500 GW non-fossil by 2030 target — India crossed 50% non-fossil early, but still needs to add ~426 GW of RE this decade.

What we don’t yet know
- Market coupling — will CERC implement it, and how much of IEX’s economics does it actually take? The single biggest binary in the sector.
- The PFC–REC swap ratio — unset; it’s the decisive number for REC minority holders and the merged entity’s float.
- Whether the transmission build catches up to RE — curtailment is the tax on getting this wrong; the FY27 commissioning pace matters.
- The coal transition clock — how long does Coal India’s cash machine run, and does demand peak this decade or next?
- Execution on the priced-for-perfection names — Adani Green’s 50 GW, NTPC Green’s 60 GW, JSW’s 30 GW: the multiples assume on-time delivery.
- Discom durability — is the FY25 profit a turn or a blip? Smart-metering has already slipped to March 2028.
