Turnkey Power System EPC Services
Designing safe and reliable power systems from concept to commissioning
At Elliot Engineering, our Turnkey Power System EPC Services prioritize customer success through rigorous safety standards and proven industry methodologies. As specialists in High-Voltage (HV) transmission and Medium-Voltage (MV) unit substation engineering, we handle every aspect of your power system project, from initial conceptual design to final utility interconnection, with technical precision.
Our process begins by defining the substation design based on form, fit, function, and specific grid requirements. We collaborate with your team to develop protection single-line diagrams, physical layouts, and elevations that ensure site compatibility and future scalability. We provide comprehensive power system analysis, including load flow, short circuit, grounding, and arc flash studies, to establish a detailed engineering foundation. This data-driven approach ensures that all design concepts are actionable and tailored to meet both your operational goals and NERC/utility compliance mandates.
Substation Design and Engineering Services
We provide full-spectrum design for power generation, transmission, and distribution networks, including main power infrastructure and critical ancillaries. Our expertise extends to renewable energy applications, such as BESS (Battery Energy Storage Systems), wind, and solar integration, where we optimize layouts for maximum efficiency.
Every design-build project benefits from our advanced substation design and engineering services, which include the development of detailed Equipment Specifications, Bills of Material (BOM), and Protection & Control (P&C) schematics. We utilize state-of-the-art modeling tools to simulate system performance, ensuring seamless integration of communication, automation, and smart grid systems. Whether managing a greenfield installation or a complex brownfield retrofit, we adhere to IEEE, ANSI, and NEC standards to guarantee long-term reliability.

Our Process
Delivering safe, reliable substations starts with a disciplined process grounded in power system analysis and real-world field experience. We combine rigorous engineering standards with practical constructability reviews so owners get designs that perform as expected in service, not just on paper.
Our Substation Design and Engineering Services follow a structured lifecycle:
- Power System Studies and Feasibility: We perform load flow, short circuit, and arc flash studies to define project scope and ensure safety compliance with NFPA 70E.
- Concept Development: Preliminary layouts and 3D models evaluate site constraints, phasing options, and future expansion needs.
- Strategic Procurement: Managed by our PMO, we identify long-lead items like transformers and switchgear early. We utilize a pre-qualified vendor database to ensure all equipment meets ISO 9001 and utility standards.
- Detailed Engineering: This includes physical, civil, and structural design, including foundations, rigid/flexible bus arrangements, and cable routing.
- Protection, Control, and Grounding: We design lightning protection and grounding grids to meet IEEE 80 standards, integrating modern SCADA and automation protocols.
- Project Management Oversight: We use tools like Primavera P6 for scheduling and Earned Value Management (EVM) to keep projects on track and within budget.
- Construction and Safety: We enforce strict adherence to OSHA 1910 and NESC requirements. Our partners follow a Quality Control Plan (QCP) featuring daily safety briefings and Job Hazard Analyses (JHAs).
- Testing and Commissioning: Before handover, we conduct NETA ATS compliant testing, including insulation resistance, transformer turns ratio (TTR), and protective relay verification.
- Project Closeout: We provide a comprehensive handover package including as-built drawings, NETA test reports, and equipment manuals to ensure total operational readiness.
From greenfield high-voltage yards to brownfield upgrades in live facilities, we support you from planning through energization. Our turnkey Power System EPC Services allow you to work with a single, accountable partner for the full life of your project.
