Executive Summary

▪     The FSA price is the base case, not the whole case. A Fuel Supply Agreement with Coal India Limited (CIL) or Singareni fixes a low-volatility, notified-price fuel cost that lenders treat as bankable — but delivered cost is driven as much by statutory levies and rail freight as by the coal itself.

▪     Levies plus logistics are the real swing factor. Royalty, DMF and NMET, GST, sizing charges and freight commonly account for 45–55% of the landed cost at the plant gate, so sensitivity work must model the stack, not a single ₹/tonne number.

▪     The tax base has shifted. From September 2025 the GST Council scrapped the flat ₹400/tonne compensation cess and moved coal to 18% GST, cutting power-sector cost by roughly ₹260/tonne and 17–18 paise/kWh and levelling tax incidence to a uniform 39.81%.

▪     Policy has widened optionality. The Revised SHAKTI Policy 2025 collapses eight linkage windows into two, and the new CoalSETU window opens long-term linkages to any industrial user — reshaping how much coal a project can secure and at what premium.

▪     Recommendation: model three sourcing scenarios. Anchor the base case on secured FSA volumes, then stress-test partial deviation to e-auction and index-linked imports to size the true risk-adjusted return.

1.  Problem & Context

For any coal-linked asset in India — a thermal generator, a captive cement or aluminium plant, or a downstream buyer benchmarking against thermal grids — the single most consequential assumption in the financial model is the delivered price of coal. Get it wrong and the error compounds through EBITDA, debt service and equity IRR. The FSA price sits at the centre of that assumption because it is the most defensible long-term domestic benchmark available: a contractual, notified-price arrangement that behaves very differently from spot or imported coal.

The difficulty is that the FSA “price” is not one number. It is a built-up cost — a base notified price layered with quality adjustments, statutory levies, taxes and logistics — governed by a policy framework that has moved materially in the last eighteen months. A model built on the pre-2025 tax and linkage regime is now out of date. This brief sets out how a strategy consultant should read, build and stress-test the FSA coal price today.

2.  Technology & Market Overview

What an FSA actually guarantees

An FSA is a long-term contract — typically up to 15 years for non-regulated buyers — that fixes five things: a quantity assurance expressed as a percentage of the plant's normative (annual contracted) requirement; the price-determination mechanism; grade and quality specifications; the frequency of price revision; and the escalation and pass-through rules. Because CIL is a state-owned near-monopoly, its prices are administered rather than market-cleared, which is precisely why lenders discount FSA supplies less heavily than merchant coal.

From grades to GCV

CIL prices non-coking coal against 17 grades defined by Gross Calorific Value (GCV) bands, with separate notified-price schedules for the regulated (power) sector and the non-regulated sector. The direction of travel is toward billing on actual GCV consumed rather than on a grade mid-point, aligning Indian practice with international norms. For the analyst this matters because price cannot be divorced from quality: GCV drives station heat rate, auxiliary power consumption and variable O&M, so a lower-grade coal at a lower notified price can still raise the effective cost per unit of electricity generated.

The market context is one of assured but tightening domestic supply. India crossed one billion tonnes of coal production in FY2024–25, growing output roughly 5% year on year, even as the policy objective of import substitution intensifies. Where a buyer cannot secure 100% of its requirement under FSA, the balance is met from CIL e-auctions (which clear at a premium to notified price) or from imported coal benchmarked to indices such as Newcastle or the Indonesian references — introducing exactly the volatility the FSA was meant to avoid.

3.  Economics & Cost Trajectories

Anatomy of the delivered cost

The effective landed cost of FSA coal is best modelled as a waterfall: base notified price, plus grade/sizing adjustments, plus statutory levies, plus GST, plus evacuation and transport (rail, road or a merry-go-round system), equals delivered cost to the plant. Two features dominate. First, the notified price is administered and revised periodically, so its volatility is low but its direction is upward. Second, levies and freight together frequently form 45–55% of the delivered number — meaning a project's fuel economics are as exposed to railway freight revisions and levy changes as to the coal price itself.

Escalation and sensitivity

For the base case, the FSA notified price is the core fuel input, escalated on a conservative, defensible basis — commonly a fixed real escalation of 2–4% per annum, or a pass-through assumption for regulated assets, cross-checked against CIL's historical revision cadence. The value of the analysis, however, lives in the downside cases: partial or full loss of FSA supplies, heavier reliance on e-auction or imports, faster escalation in notified prices, and increases in rail freight or levies. Each of these flows directly into EBITDA margin, operating cash flow, IRR and payback, and each should be quantified rather than asserted.

4.  Regulatory & Policy Landscape (India)

The levy stack

Delivered cost carries a layer of statutory charges levied under the Mines and Minerals (Development and Regulation) Act. Royalty on coal is charged at 14% ad valorem on the notified price; on top of that sit a contribution to the District Mineral Foundation (DMF) — up to 30% of royalty for older leases — and 2% of royalty to the National Mineral Exploration Trust (NMET). These are not rounding errors: together with sizing charges they can move the delivered number by a few hundred rupees a tonne.

The September-2025 GST reform

The most important recent change is fiscal. At its 56th meeting the GST Council removed the flat ₹400/tonne compensation cess on coal and raised the GST rate from 5% to 18%. Because the old cess was a fixed per-tonne charge, it fell hardest on low-GCV, low-price Indian coal and effectively handicapped domestic grades against high-GCV imports. Removing it aligned tax incidence across grades to a uniform 39.81% and, according to the Ministry of Coal, reduced the power sector's coal cost by around ₹260/tonne — a cut of roughly 17–18 paise per kWh — while releasing blocked input-tax credit by correcting the earlier inverted-duty anomaly.

Figure 3 — Before the reform, the flat cess pushed the most-produced grade (G11) to a 65.8% tax incidence; the reform levelled all grades to 39.81%. Source: Ministry of Coal.

The modelling implication is direct: any feasibility study or fuel cost sheet built before this reform overstates the cess line and understates GST, and should be rebuilt on the new base. This is the single most common error in coal cost models circulating today.

SHAKTI 2025 and CoalSETU

On the allocation side, the Revised SHAKTI Policy 2025 simplified eight erstwhile linkage windows into two: Window I supplies central and state generators at notified price; Window II offers coal to all generators at a premium above notified price, with the flexibility to sell power in the market rather than only under a power purchase agreement. In December 2025 the government added the CoalSETU window to the non-regulated-sector auction framework, letting any domestic industrial buyer secure long-term linkages — for own use, coal washing or export of up to half the quantity. For a project developer, this widens the menu of secured supply beyond the classic FSA and changes the premium a buyer might rationally pay for certainty.

Pass-through vs. margin risk

In regulated assets the FSA price is usually a pass-through, subject to regulatory approval and normative consumption limits, so fuel-cost risk sits largely with the off-taker. In merchant or industrial setups the FSA price is a direct margin driver, so fuel security and cost certainty carry a premium. Robust models therefore present with-pass-through and without-pass-through cases side by side.

5.  System Integration & Infrastructure

Two infrastructure realities decide whether the modelled FSA price is achievable. The first is evacuation. Rail freight is frequently the largest single line in the delivered cost, so first-mile connectivity, dedicated freight corridors and pit-head location can matter more to project economics than a grade's notified price. Locating capacity near the mine to maximise effective FSA utilisation is a legitimate strategic lever, not a detail.

The second is quality assurance. As billing shifts toward actual GCV, third-party sampling, weighbridge integrity and grade-slippage disputes become material commercial risks. A GCV shortfall against specification quietly raises the effective ₹/kWh even when the notified price is unchanged. Diligence should test the counterparty's historical grade conformance, not just the contracted grade on paper.

6.  Risks & Constraints

The principal risks cluster into four buckets, each with a corresponding mitigation that belongs in the investment case.

Risk	What it does to the model	Mitigation / model treatment
FSA quantity shortfall	Forces a shift to e-auction / imports; raises blended fuel cost and volatility	Model FSA at 65–85% of normative need; run moderate and severe sourcing cases
Notified-price / levy escalation	Erodes margin faster than assumed fixed escalation	Cross-check CIL revision history; sensitise royalty, DMF, freight independently
Freight & evacuation	Largest swing line; rail tariff hikes hit delivered cost directly	Prioritise pit-head / first-mile connectivity; test rail-tariff scenarios
GCV / quality slippage	Raises effective ₹/kWh even at a constant notified price	Third-party sampling; diligence on counterparty grade-conformance record

 

India in a global frame

India's administered FSA model is not unique. Indonesia operates a Domestic Market Obligation with a capped domestic reference price to shield local buyers from export benchmarks; China blends long-term contract prices with a market range; and merchant markets price wholly against seaborne indices. The FSA's comparative advantage is stability and bankability; its comparative weakness is exposure to policy-driven revisions and evacuation bottlenecks. Any cross-border cost benchmarking should compare like-for-like on a GCV-adjusted, delivered basis rather than headline ₹ or $/tonne.

7.  Strategic Options & Roadmap

Horizon	Objective	Actions
Near-term (0–12 mo)	Rebase the model	Rebuild fuel cost on the post-Sept-2025 GST base (18%, no cess); lock the FSA base case at 65–85% of normative need; run the three-scenario sourcing ladder.
Mid-term (1–3 yr)	Secure & diversify supply	Evaluate SHAKTI Window II and CoalSETU linkages to top up or replace FSA volumes; quantify the premium worth paying for certainty; firm up first-mile / rail evacuation.
Long-term (3–7 yr)	Hedge structural exposure	Position for GCV-based billing and tightening domestic supply; benchmark against storage and RE-plus-firming alternatives where coal is a customer-economics reference rather than a direct input.

Conclusion

The FSA coal price remains the most defensible anchor for coal-linked project economics in India, but it is an anchor, not the whole vessel. Its bankability comes from administered stability; its risk comes from the levy-and-freight stack around it and from a policy frame that has just moved. A credible 2026 analysis rebuilds the fuel cost on the post-reform GST base, prices in the widened optionality of SHAKTI 2025 and CoalSETU, and quantifies — rather than assumes — the cost of deviating from secured FSA volumes. Do that, and the FSA price stops being a static input and becomes a genuine lever of risk-adjusted return.
