Enviro Infra Engineers Limited Achieves Order Book Milestone and Segment Diversification

Summary of Recent Developments

Enviro Infra Engineers Limited (EIEL) has reached a current total order book valuation exceeding ₹4,600 Crore, marking a significant expansion in its domestic infrastructure portfolio. This growth is underpinned by the company’s strategic entry into the Battery Energy Storage Systems (BESS) segment, a move designed to capitalize on India’s evolving renewable energy requirements.

Order Book Valuation and Growth Metrics

The company’s recent financial milestones indicate an accelerated scaling of operations:

• Total Order Book Valuation: The current aggregate value exceeds ₹4,600 Crore.
• Recent Order Inflow: Since March 2024, the company has secured more than ₹2,240 Crore in new orders.
• Historical Context: This trajectory builds upon a 42% year-over-year growth in the order book recorded as of FY24, according to SMIFS data.
• Strategic Growth: The current scale reflects the successful conversion of bids in both the traditional water sector and the emerging power storage market.

Strategic Expansion into Battery Energy Storage Systems (BESS)

EIEL has diversified into the renewable energy storage sector through a contract with NTPC Limited. The agreement carries an immediate Engineering, Procurement, and Construction (EPC) value of ₹664.33 Crore, with a total lifecycle contract value estimated at ₹1,070 Crore. The project covers a total capacity of 930 MWh.

The BESS rollout involves the following NTPC station locations:

Technical and Economic Context Technically, these systems manage steep evening ramp-up rates—which fluctuate from 25GW/hour to over 40GW/hour under stress—and mitigate renewable energy curtailment by storing surplus midday generation. From a financial perspective, BESS diversification is strategic; standalone projects under the Central Electricity Regulatory Commission (CERC) cost-plus framework can deliver equity IRRs exceeding 30%, compared to single-digit returns in tariff-based competitive bidding. While headline tariffs appear low, the effective cost of delivered energy from BESS is estimated at ₹6.5–₹7.5/kWh after adjusting for degradation and efficiency losses.

Operations Update: Core Water and Wastewater EPC Projects

The company continues to execute its primary business in water infrastructure, leveraging both EPC and Hybrid Annuity Model (HAM) structures.

• AMRUT 2.0 Initiatives: Ongoing projects in Bihar are focused on universal sewerage and urban water supply strengthening.
• Regional Activity: Significant project execution is currently concentrated in Maharashtra and Uttar Pradesh.
• HAM Project Specifics: Key ongoing HAM projects include the 63 MLD facility in Bareilly and the 60 MLD facility in Mathura. These projects require the company to manage 60% of capital costs and long-term O&M, providing stable, recurring revenue.
• Core Project Types: EIEL specializes in Sewage Treatment Plants (STPs), Common Effluent Treatment Plants (CETPs), and Water Supply Scheme Projects (WSSPs).
• Technological Standards: Most facilities are Zero Liquid Discharge (ZLD) compliant, facilitating the reuse of treated water for industrial and refrigeration processes.

Sustainable Development and Waste-to-Energy Initiatives

EIEL is integrating green energy components into its infrastructure to enhance the circular economy of water and improve margins.

• Sustainable Project Integration: Currently, 7 of 21 active projects incorporate solar and Compressed Bio Gas (CBG) components.
• Solar Power Implementation: Operational solar sites include Kota (1 MW), Bareilly (800 kW), and Bikaner (3 MW). Additional installations are progressing in Jodhpur, Bhiwadi, Jaipur, and Varanasi.
• Revenue Enhancement: The company intends to sell purified CBG to Oil Marketing Companies (OMCs). This strategy is designed to generate supplementary revenue to offset Operation and Maintenance (O&M) costs.

Revenue Outlook for Fiscal Year 2027

The revenue outlook for the 2027 fiscal year is based on the current order inflow and the phased deployment timeline of the NTPC BESS contract. While a specific numerical target has not been established, the growth trajectory is extrapolated from a historical Compound Annual Growth Rate (CAGR) of 82.1% recorded between FY22 and FY24. Future revenue stability is expected to be supported by the shift toward high-capacity STPs (up to 200 MLD) and the higher-margin BESS segment.

Corporate Profile and Market Positioning

Enviro Infra Engineers Limited (EIEL) is a specialist in the design, construction, and operation of water infrastructure for government authorities. Its growth is supported by several central government mandates:

• Jal Jeevan Mission (JJM): Rural water supply schemes.
• AMRUT 2.0: Urban water and septage management.
• National Mission for Clean Ganga (NMCG): Pollution abatement in the Ganga basin.

The company is currently expanding its geographical footprint beyond its established presence in North and West India, submitting active bids for new projects in Odisha, West Bengal, and Goa.
