Asset classification and cost to cure in a captive gas-engine power plant
A 24 MW captive gas-engine power plant supports a chemical unit. The plant comprises two 12 MW natural gas engines, 11 kV switchgear, a 3 km dedicated 33 kV transmission line on private right of way, a 45 m reinforced-concrete exhaust chimney, and a 1,500 kVA standby DG set. Replacement cost new is: engines ₹72 crore (both), switchgear ₹9 crore, transmission line ₹6.5 crore, chimney ₹4.2 crore, and DG set ₹1.8 crore. Average age is nine years and the technical life is 25 years. The plant does not meet the new NOx limit; a selective catalytic reduction system costing ₹7.5 crore must be installed. The consent to operate expires in eight months. A bank is considering the plant as collateral and asks whether the chimney and transmission line are plant and machinery.
1. Classify each component as plant and machinery or land and building, and compute the P&M replacement cost new.

Classification.
- Gas engines: plant and machinery. They are the process asset.
- 11 kV switchgear: plant and machinery; electrical installation integral to generation and evacuation.
- Dedicated 33 kV transmission line: plant and machinery if it is owned by the plant and used solely to evacuate its power. The right of way is an easement, not land owned by the plant, so no land value is included. If the line is a public utility asset or the right of way has independent value, reclassify.
- 45 m reinforced-concrete exhaust chimney: land and building. It is a civil structure, even though it serves the engines. If it were a steel exhaust stack supplied as part of the engine package and removable with the engines, it would be plant and machinery.
- 1,500 kVA standby DG set: plant and machinery; it is required for safe shutdown and emergency supply.
P&M replacement cost new.
Engines ₹72.0 crore + switchgear ₹9.0 crore + transmission line ₹6.5 crore + DG set ₹1.8 crore = ₹89.3 crore.
The chimney’s ₹4.2 crore is excluded from P&M and dealt with under land and building.
2. Compute the RCNLD after the NOx compliance cost, and explain why the cure cost is deducted after depreciation of the compliant asset.

Compliant benchmark.
RCN of P&M as-is = ₹89.3 crore.
Add SCR cost = ₹7.5 crore.
RCN of compliant P&M = ₹96.8 crore.
Physical deterioration.
Age-life = 9 ÷ 25 = 36%.
RCNLD of compliant P&M = ₹96.8 crore × (1 − 0.36) = ₹61.95 crore.
Deduct cost to cure.
The buyer of the nine-year-old plant must install a new SCR now. The compliant benchmark assumes a nine-year-old SCR, but the actual cure is at current cost. Therefore deduct the full ₹7.5 crore:
₹61.95 crore − ₹7.5 crore = ₹54.45 crore.
Why not deduct from ₹57.15 crore?
Using the as-is RCN of ₹89.3 crore gives ₹57.15 crore. Deducting the full ₹7.5 crore from that figure gives ₹49.65 crore, which treats the missing SCR as having no value while also charging for it. The compliant-benchmark method is internally consistent: the buyer pays ₹54.45 crore for the plant and spends ₹7.5 crore, resulting in a compliant asset worth ₹61.95 crore. The valuer should disclose that the cure cost excludes shutdown, permit delay, and any penalty.
3. How should the expiring consent to operate affect the valuation and the bank’s collateral position?
Read the worked answer
Effect on value. After expiry, the plant cannot legally operate. A going-concern value is therefore conditional on renewal. The valuer should not present an unconditional going-concern figure. The report should state a “subject to renewal” assumption, obtain the renewal status or a credible timeline, and consider a risk adjustment for the period of possible shutdown.
Collateral position. A bank should not rely on going-concern value if the consent is not renewed. The lender should treat the asset as having a liquidation or as-is value until the consent is in hand. The compliance cost of ₹7.5 crore is only the equipment cost; the lender should also consider the time to procure and install the SCR, the shutdown required, and the possibility that the consent is refused.
Practical recommendation. Structure the valuation with two scenarios:
- Cured going-concern value of ₹54.45 crore, assuming renewal and SCR installation.
- Uncured as-is value, which may be substantially lower and should be based on the plant’s realisable value without a valid consent.
The bank should withhold reliance on the higher figure until the consent is renewed or an escrow is funded for the cure and shutdown costs.
