Introduction
In a significant judgment protecting consumer interests, the Supreme Court has held that electricity consumers cannot be burdened with depreciation costs of a power plant for the period during which they did not receive electricity supply from that plant.
Background of the Case
The dispute arose over the Rithala Combined Cycle Power Plant in Delhi, which was established to meet increased electricity demand during the 2010 Commonwealth Games.
The plant was originally intended to operate for a limited period of around six years. However, the power distribution company later sought to recover depreciation costs for the plant’s entire technical life of 15 years, even after it stopped supplying electricity to consumers in March 2018.
Regulatory History
The Delhi Electricity Regulatory Commission (DERC) had approved recovery of depreciation only for the period during which electricity was actually supplied to consumers.
However, the Appellate Tribunal for Electricity (APTEL) later permitted the company to recover depreciation over the plant’s full 15-year useful life, despite cessation of supply.
This decision was challenged before the Supreme Court.
Supreme Court’s Key Observation
The Supreme Court set aside the APTEL order and ruled that:
- Consumers cannot be required to pay for a service they no longer receive
- Power companies do not have an unconditional right to recover the full capital cost of a plant from consumers after supply has stopped
- Tariff determination must balance cost recovery with protection of consumer interests
The Court emphasized that consumer welfare is a core principle under the Electricity Act, 2003.
Court’s Legal Reasoning
The Bench observed that:
- Under the Power Purchase Agreement (PPA), electricity supply from the plant was intended only for a fixed six-year period
- After that period, the company was free to sell electricity elsewhere as a merchant generator
- Since consumers did not receive electricity after March 2018, they could not be made to bear further tariff burdens linked to the plant
The Court also clarified that the technical life of a power plant does not automatically entitle a company to recover depreciation costs for the entire duration from consumers.
Importance of the Ruling
This judgment is significant because it:
- Strengthens consumer protection in electricity tariff matters
- Clarifies limits on recovery of infrastructure costs
- Reinforces that tariff decisions must remain fair and reasonable
- Prevents consumers from paying for unused or discontinued services
Conclusion
The Supreme Court has reaffirmed that electricity consumers cannot be treated as perpetual sources of cost recovery once supply has ceased. The ruling highlights that regulatory decisions must prioritize fairness and ensure that consumers pay only for services they actually receive.
