The energy sector is categorized as a regulated sector under the Cost Audit Rules. This includes power generation and distribution, oil refining, coal mining, and gas production.
Why is cost audit mandatory here? Because energy pricing affects national infrastructure, public utility services, and inflation control.
Power Sector: Mandatory Cost Audit Applies
All companies engaged in:
- Electricity generation (thermal, hydro, solar, wind)
- Electricity transmission and distribution
- Power trading and bulk supply
are required to maintain cost records and, if they meet turnover thresholds, file cost audit reports under CRA-3.
Thresholds for Cost Audit in Power Companies
| Criteria | Threshold |
| Overall turnover | > Rs. 50 crore |
| Revenue from regulated activity | > Rs. 25 crore |
So, if your solar plant earns Rs. 30 crore out of a total Rs. 60 crore turnover, you must comply with cost audit norms.
Power distribution companies (DISCOMs), independent power producers (IPPs), and renewable energy players are not exempt from cost audit if criteria are met.
Oil & Gas Sector: CRA Applicability in 2025
Companies involved in:
- Oil refining and petrochemicals
- Natural gas extraction
- Coal mining and processing
- LPG and CNG bottling
- Crude oil import and refining
are also included in the regulated category for cost records and audit.
Many PSUs and private oil majors in India like IOCL, BPCL, ONGC, and Reliance must file CRA reports annually for their refineries and gas infrastructure.
Turnover Thresholds for Oil & Gas Cost Audit
Same as other regulated sectors:
| Criteria | Threshold |
| Total turnover | > Rs. 50 crore |
| Revenue from regulated product | > Rs. 25 crore |
Companies like city gas distributors, pipeline operators, and energy traders must also analyze if their revenue mix meets audit criteria.
Cost Records & CRA Templates for Energy Sector
Energy companies must prepare cost records in CRA-1 format, which includes:
- Fuel usage & energy efficiency metrics
- Depreciation on plant and equipment
- Production capacity vs. actual utilization
- Operating margins by energy product
Power and energy sectors often have huge capex and regulatory oversight, making cost audits crucial for tariff planning and government reporting.
Pro Tip for Compliance:
Energy companies often face regulatory scrutiny from CERC, DERC, and PNGRB. Cost audit reports under CRA-3 add credibility and
