SPML Infra partnerships and signals
Strategic signalPartnerships
Five partnerships are on record, tiered core and flagship.
- Energy VaultcoreSPML Infra entered an exclusive agreement with US-based Energy Vault, a global leader in sustainable energy storage solutions, to bring cutting-edge battery energy storage system technology to India. This partnership enables SPML Infra to deliver grid-scale BESS projects (such as the 250 MW/1,000 MWh NTPC Barauni project) and provides technology support for system optimization and grid reliability, marking SPML Infra's strategic entry into India's growing energy storage sector.
- NTPC LimitedflagshipSPML Infra secured a ₹1,128 crore contract from NTPC Limited — one of the largest single BESS orders awarded in India — to develop a 250 MW/1,000 MWh Battery Energy Storage System at NTPC's Barauni Thermal Power Station in Bihar. The project involves complete design, engineering, supply, construction, installation, testing, and commissioning over 18 months, followed by 15 years of O&M. This marks SPML Infra's first large-scale grid BESS project and entry into the utility-scale energy storage segment.
- JWIL Infra and Vishnusurya Projects & InfracoreSPML Infra, as part of a consortium with JWIL Infra and Vishnusurya Projects & Infra, was awarded a ₹344.64 crore contract by the Chennai Metropolitan Water Supply and Sewerage Board for implementing continuous water supply systems at Pallipatu and Thiruvanmiyur water distribution stations under the Hybrid Annuity Model.

SPML Infra competitors and assessment
Company assessmentDirect peers
- VA Tech Wabag: India-listed pure-play water EPC company focused on municipal water and wastewater treatment plants globally. Most directly comparable to SPML's water infrastructure segment in terms of customer base (government utilities), technology (treatment plants) and project execution model.
- KEC International: India-based EPC company with significant exposure to power transmission (substations, towers) and cables. Highly comparable to SPML's power infrastructure business (e.g., RRVPNL 400 kV grid substation) in terms of customer profile (state electricity boards) and project type.
- Kalpataru Projects International: Diversified Indian EPC group operating across power transmission, water, oil & gas, and buildings. Comparable business mix to SPML, particularly in power T&D and water pipeline/treatment execution, with similar reliance on government and utility clients.
- Tata Projects: Large Indian EPC company covering power transmission, water, and emerging clean energy infrastructure. Competes with SPML on government tenders for substations, water supply systems, and increasingly BESS projects, but at materially larger scale.
- NCC Limited: Indian infrastructure construction company with significant water supply, irrigation, and urban infrastructure exposure. Comparable to SPML in tender-driven water EPC business, particularly under Jal Jeevan Mission and AMRUT schemes.
- HG Infra Engineering: Indian EPC contractor executing highways, water supply, and irrigation projects under government schemes. Comparable mid-cap infrastructure peer to SPML with similar dependence on central/state government contracts and HAM/EPC models.
- Ion Exchange (India): India-based water and environment management company providing treatment plants, desalination, and zero liquid discharge systems. Comparable to SPML's advanced water treatment and ZLD offerings, with strong overlap in industrial and municipal water customers.
Broad incumbents
- Larsen & Toubro (L&T): India's largest EPC conglomerate with dominant positions in power T&D, water, hydrocarbons, and increasingly BESS. Competes head-to-head with SPML on government tenders but operates at vastly larger scale and broader portfolio depth.
Emerging players
- Engineers India Limited: Government-owned engineering consultancy and EPC contractor with strong water and infrastructure credentials. Partially overlaps SPML in design engineering and EPC project execution for public sector clients.
- Thermax Limited: Indian energy and environment solutions provider with water and wastewater treatment business. Partial overlap with SPML's wastewater treatment and ZLD systems, though Thermax skews more toward industrial clients than municipal utilities.
