TERC Approves ₹12.75 Billion Tariff Recovery: TSECL Revenue Gap Reduced and Separate Surcharge Avoided

Executive Summary of the Regulatory Ruling

On May 4, 2026, the Tripura Electricity Regulatory Commission (TERC) issued a comprehensive tariff order for the financial year (FY) 2026–27. Following a rigorous prudence check of the Multi-Year Tariff (MYT) petition submitted by the Tripura State Electricity Corporation Limited (TSECL), the Commission approved a total tariff recovery of ₹12.75 billion. The revised rates are effective from May 1, 2026. In a move to prioritize consumer protection, TERC explicitly rejected the 43% tariff hike originally proposed by the utility. The ruling seeks to stabilize the utility’s financial health while avoiding the “tariff shock” associated with the full recovery of accumulated regulatory assets in a single fiscal cycle.

Financial Analysis: Requested vs. Approved Revenue

The Commission’s determination follows a detailed synthesis of TSECL’s Aggregate Revenue Requirement (ARR). While the utility sought to bridge a cumulative revenue gap of ₹17.09 billion, the Commission identified a significant discrepancy between the utility’s claimed Average Cost of Supply (ACoS) of ₹18.13/kWh and the determined ACoS of ₹8.90/kWh.

The financial determination includes ₹1.50 billion in carrying costs on approved gaps and approves TSECL’s own generation costs at ₹1.78 billion. The following table contextualizes the requested revenue against the Commission’s final determination:

Phased Recovery Strategy and Surcharge Rejection

To address the liquidation of regulatory assets, TERC adopted a phased recovery mechanism aligned with the legal precedent established by the Supreme Court in BSES Rajdhani Power Ltd. vs. Union of India. This ruling mandates the liquidation of past regulatory gaps within seven years and current gaps within three years. Consequently, the Commission did not allow the entire truing-up gap to be passed through immediately.

The phased recovery fractions integrated into the current ARR are:

• Recovery of one-fifth (1/5) of the approved true-up gap for FY 2023–24.
• Recovery of one-third (1/3) of the approved true-up gap for FY 2024–25.

TERC rejected TSECL’s proposals for both a “One-Time Regulatory Surcharge” and a standard “Regulatory Surcharge.” The Commission directed that all approved costs be recovered through rationalized base tariffs to ensure transparency and predictability in consumer billing.

Breakdown of Revised Tariff Rates

The revised energy charges reflect a tiered structure designed to mitigate impact on low-consumption households while moving tariffs closer to the cost of supply.

• Domestic Consumers:
  • 0-50 and 51-150 unit slabs: Increase of 15 paise per unit.
  • >150 unit slabs: Increase of 20 paise per unit.
• Special Categories:
  • Irrigation, Public Water Works, and Public Lighting: Increase of 20 paise per unit.
• All Other Categories:
  • Increase of 35 paise per unit.

For domestic single-phase and commercial consumers, the Commission upheld the reform of billing fixed charges based on connected load (Rs/kW) rather than a flat connection rate.

Renewable Energy and Operational Directives

The order emphasizes grid modernization and renewable energy adoption through specific technical mandates:

• Green Tariff: Retained at ₹0.75 per kWh for voluntary procurement of renewable energy.
• Time of Day (ToD) Billing: A mandatory framework for most categories (excluding small domestic and irrigation) to optimize load factors:
  • Solar Hours (9 AM–5 PM): Billed at 80% of the normal tariff.
  • Peak Hours (5 PM–10 PM): Subject to higher differentiated rates to discourage peak-load stress.
• Efficiency and Technical Mandates: TSECL must implement several directives to improve operational accountability:
  • Completion of feeder energy audits within six months.
  • Full financial segregation of the generation and transmission business units.
  • Implementation of boundary metering and voltage-wise loss measurement.
  • Mandatory rollout of smart meters as a prerequisite for effective ToD implementation.
• Load Management: An automatic load restatement mechanism is now active. If maximum demand exceeds the contracted limit for three consecutive months, the load is revised upward. Conversely, consumers may seek a downward revision if their actual demand remains consistently below the contracted load for three consecutive months.

Sectoral Rebates and Continued Incentives

TERC has maintained a 10% rebate on energy charges to support critical sectors and remote infrastructure:

• Homestays and hospitals in remote areas.
• Mobile towers in remote locations.
• IT and ITES (Information Technology Enabled Services) industries.
• Commercial and industrial activities operated by registered Women Self-Help Groups (SHGs).

A critical component of this framework is the Conditional Subsidy Trigger: the ₹0.77 billion government subsidy must be paid to TSECL in advance on a monthly basis. Should the government fail to provide this subsidy for two consecutive months, the utility is authorized to recover the full, non-subsidized tariff from consumers.

Utility Performance and Distribution Targets

The Commission has set aggressive efficiency benchmarks to reduce the financial burden of distribution losses. For FY 2026–27, the distribution loss target is 18.30%, a significant reduction mandate given the actual loss of 27.56% in FY 2024–25.

The approved power purchase costs total ₹16.18 billion. The transmission cost component is specifically approved at ₹1.14 billion for interstate transmission and ₹392.4 million for intrastate transmission. To ensure compliance with grid modernization goals, TSECL is required to submit quarterly reports regarding the progress and deployment of smart meters.
