Calorific value is the biggest lever
Coal is, fundamentally, sold as energy — so GCV is the single largest driver of price. A higher-GCV tonne costs more because it carries more usable heat. Comparing prices without comparing GCV is meaningless; see the grade-wise GCV ranges for context.
Ash and moisture — you pay to haul and dispose of both
High ash and moisture pull usable energy down and add handling and disposal cost, so two tonnes at the same GCV aren't equal if their ash differs. Cleaner coal commands a premium for good reason.
Source and command area
Where the coal comes from shapes both grade and freight. Proximity to the WCL, SECL or SCCL command area nearest your plant shortens the haul; imported coal carries port handling and a longer chain.
Logistics: mode and distance
Freight is often half the delivered cost. Rail rake vs road economics, distance from the yard, and siding access all move the final number — which is why a nearby yard network matters to price, not just convenience.
Market and seasonality
Domestic availability, monsoon-season logistics, port congestion and global seaborne prices all flex coal pricing through the year. Locking grade and cadence early helps insulate a plant from the swings.
Compare quotes fairly
Reduce every quote to delivered cost per useful kilocalorie — GCV net of ash and moisture, plus freight to your gate. Ask us to quote on that basis and the genuinely cheaper option becomes obvious.
Frequently asked
- Why does coal price vary so much?
- Because price tracks usable energy and delivery cost, not tonnage alone. Calorific value, ash and moisture, source/command area, logistics mode and distance, and market conditions all move it.
- What is the most important factor in coal price?
- Calorific value (GCV) — coal is sold as energy, so higher GCV means more usable heat per tonne and a higher price. Ash, moisture and freight then adjust the real delivered cost.
- How do I compare two coal quotes fairly?
- Convert both to delivered cost per useful kilocalorie: GCV adjusted for ash and moisture, plus freight to your plant gate. Comparing rupees per tonne alone is misleading.
