G9 coal shortage at Singareni raises Yadadri plant cost concerns
The 5x800 MW Yadadri Thermal Power Station at Dameracherla in Nalgonda district, taken up by the previous BRS government, needs 14 million tonnes of G9 grade coal annually, but Singareni supplies only 4 million tonnes of G9 out of 60 million tonnes produced, government sources said. Located 270 km from the mines, transport over 40 years would add ₹40,000 crore, doubling generation cost from ₹5 per unit. Coal is now being sought from Mahanadi Coalfields or Coal India.

Analysts’ view opinion
Yadadri's core problem is not construction — it is fuel economics and siting. With the plant reportedly needing 14 million tonnes of G9 coal a year against Singareni's 4 million tonnes, the state must buy the balance from Mahanadi Coalfields or Coal India, which weakens its bargaining position on fuel cost. Government sources put the 270 km distance from the mines at ₹40,000 crore of extra transport cost over a 40-year life, and say generation cost could double from ₹5 a unit — and someone, whether consumers through tariffs or the budget through subsidy, ultimately pays that.
- Coal and its freight dominate thermal generation cost, so building away from the pithead locks in a lifetime structural cost penalty.
- If per-unit cost doubles, the burden passes to discoms and from there to consumer tariffs or state subsidy — it does not disappear.
- Costlier plants slip down the merit-order dispatch queue, meaning fixed costs may still be paid even if the plant runs below capacity.
- Lacking a captive G9 supply base, dependence on outside suppliers adds both price risk and supply-security risk.
- On the other side, an ultra-supercritical plant and added state-owned baseload capacity are real benefits — but that gain is limited if fuel costs stay high.
What to watch — Watch the price and tenure of any Mahanadi Coalfields or Coal India supply deal, and how the regulator treats the higher fuel cost in tariffs.

Context
The Yadadri Thermal Power Station (YTPS), a 5x800 MW ultra-supercritical coal plant at Dameracherla in Nalgonda district, was taken up by the previous BRS government in Telangana in 2015 with BHEL as contractor on a nomination basis. The plant is designed to run on G9 grade coal, but Singareni Collieries, the State-linked coal producer, cannot supply the volumes required. With the plant located 270 km from the Singareni mines, government sources say transport costs over its life will sharply raise the cost of generation, and the State is now looking to Mahanadi Coalfields or Coal India for supply.
Key facts
- YTPS at Dameracherla, Nalgonda district, is a 5x800 MW ultra-supercritical thermal power station taken up by the previous BRS government.
- The plant needs 14 million tonnes of G9 grade coal annually to run at rated capacity.
- Singareni produces only 4 million tonnes of G9 grade coal out of an average annual output of 60 million tonnes.
- The BRS government signed the coal supply agreement with Singareni Collieries in 2022, but Singareni cannot supply the required quantities.
- The plant site is 270 km away from the Singareni coal mines.
- Coal transportation over the plant's lifetime of about 40 years would add ₹40,000 crore to generation cost, doubling it from the normal ₹5 per unit.
- The project was taken up in 2015 with a three-year completion plan and the construction contract given to BHEL on a nomination basis.
- Initial plan: first two units to be commissioned by October 2020 and remaining three by October 2021; one unit is yet to be completed.
Timeline
- 2015YTPS taken up, with construction contract handed to BHEL on a nomination basis and a three-year completion plan.
- October 2020First two units were supposed to be commissioned as per the initial plan.
- October 2021Remaining three units were supposed to be commissioned as per the initial plan.
- 2022BRS government entered into the coal supply agreement with Singareni Collieries.
- As of September 24, 2026 (report date)One unit is yet to be completed; government/Genco plans to source coal from Mahanadi Coalfields or Coal India on the Chief Minister's instructions.
Who has a stake
- Telangana government / Genco — Bears the cost burden of the plant and is now planning to source quality coal from Mahanadi Coalfields or Coal India.
- Singareni Collieries — Signed the 2022 supply agreement but produces only 4 mt of G9 coal; was not allowed by the previous government to bid in coal block auctions.
- Previous BRS government — Faulted by government sources for ignoring the coal linkage and the plant's distance from mines while setting up YTPS.
- BHEL — Got the construction contract on a nomination basis in 2015; the project remains incomplete beyond the planned schedule.
- Chief Minister A. Revanth Reddy — Has instructed that the required quality and quantity of coal be sourced from Mahanadi Coalfields or Coal India.
- Electricity consumers in Telangana — Face the prospect of generation cost doubling from ₹5 per unit due to long-distance coal transport.
Why it matters
A 4,000 MW plant without an assured fuel linkage of the right grade shows how siting and coal-linkage decisions, not just capital cost, determine whether power is affordable. If transport adds ₹40,000 crore over 40 years and doubles the ₹5 per unit cost, the burden ultimately flows to the State's finances and consumers. It also highlights the cost of delays: units planned for 2020-21 are still incomplete.
UPSC angle
Prelims pointers
- YTPS at Dameracherla, Nalgonda district: 5x800 MW ultra-supercritical thermal power station.
- G9 is a grade of coal; YTPS needs 14 million tonnes of G9 annually at rated capacity.
- Singareni Collieries produces 4 million tonnes of G9 out of about 60 million tonnes average annual output.
- YTPS is located 270 km from Singareni coal mines; transport cost over 40 years estimated at ₹40,000 crore.
- BHEL received the YTPS construction contract in 2015 on a nomination basis.
- Alternative coal sources being considered: Mahanadi Coalfields and Coal India.
Mains framing
The YTPS case illustrates a classic failure of fuel-linkage planning in thermal power: a 5x800 MW ultra-supercritical station was taken up in 2015 and a coal supply agreement signed with Singareni only in 2022, yet the miner produces just 4 million tonnes of the G9 grade the plant needs 14 million tonnes of annually. Compounding this, the plant sits 270 km from the mines, whereas pit-head siting is the economical option; government sources estimate ₹40,000 crore of transport cost over a 40-year life, doubling generation cost from ₹5 per unit. Institutional choices worsened the outcome: the contract went to BHEL on a nomination basis, commissioning slipped from the October 2020-2021 targets with one unit still incomplete, and Singareni was reportedly not permitted to bid for coal blocks that could have secured greenfield supply. The way forward, as indicated in the source, lies in tying up assured quality and quantity of coal from Mahanadi Coalfields or Coal India, and more broadly in ensuring that fuel grade, linkage and transport logistics are settled before capacity is sanctioned, so that tariff impact on consumers and State finances is contained.

- Nomination basis contract
- Award of work directly to a party without competitive bidding; BHEL got the YTPS construction contract this way in 2015.
- Singareni Collieries
- The coal producer with an average annual output of about 60 million tonnes that signed the 2022 supply pact with YTPS.
- Mahanadi Coalfields / Coal India

Practice questions
- Discuss how coal linkage and plant siting decisions affect the cost of thermal power generation, using the Yadadri Thermal Power Station as an illustration.
- Examine the fiscal and consumer implications when a State-owned generation project is commissioned without an assured fuel supply of the required grade.
- What are the risks of awarding large power project contracts on a nomination basis rather than through competitive bidding?
