Engineering, Procurement
& Construction

Complete project execution from concept to commissioning — delivered efficiently, safely, and exactly to specification.

Services

Core Services

Our EPC services span the full BESS lifecycle — from site survey to energisation. We take single-point responsibility for engineering, procurement, construction, and commissioning, so you deal with one team, one contract, and one accountable partner.

Engineering Design

Comprehensive system design and technical planning, optimised for performance, safety, and long-term reliability — every system sized around your specific load profile, site constraints, and duty cycle.

Procurement Management

Strategic vendor coordination and material sourcing that secures quality components at competitive prices, delivered on time — with core battery systems built in-house at our cell-to-pack facility in Pune.

Construction & Installation

On-site build-out managed under strict quality-assurance protocols, safety compliance, and schedule discipline, with documented inspections and progress reporting at every milestone.

Testing & Commissioning

Rigorous system validation, performance testing, and formal handover procedures that guarantee operational readiness from the moment the asset is declared live.

Our Approach

Built to Specification.
Delivered on Schedule.

Our construction teams work to rigorous quality-management frameworks, so every installation meets international standards and client specifications without compromise. The result is infrastructure that is delivered on time, performs to its rated specification on day one, and is engineered to keep doing so for decades.

Our Approach

From Concept to Commissioning

Every EPC engagement follows a disciplined six-stage path that takes the project from an idea to a fully operational, warranty-backed asset.

01

Feasibility & Site Assessment

Technical and commercial evaluation of project viability — including site surveys, grid-interconnection studies, load analysis, and regulatory-compliance review — so the project starts on solid ground.

02

Detailed Engineering

System architecture, electrical design, civil engineering, and construction-ready documentation prepared to international standards and approved before a single component is ordered.

03

Procurement & Logistics

Vendor qualification, in-house battery manufacturing, component sourcing, contract negotiation, and coordinated logistics planning to keep the schedule on track.

04

Construction & Installation

On-site execution with dedicated project management, safety oversight, quality inspections, and transparent progress reporting at every stage.

05

Testing & Commissioning

Systematic validation of all systems, performance verification against design specifications, and formal handover to operations.

06

Post-Commissioning Support

Warranty management, defect-liability-period support, and a smooth transition into long-term Operations & Maintenance programmes.

Why ST Energy

Why ST Energy for EPC

Three decades of HT/LT substation and grid-infrastructure experience sit behind every project. That heritage means we understand not just the battery, but the switchgear, protection, civil works, and grid interconnection that determine whether a storage plant actually performs once it is live.
