Precision-engineered electrical layouts and system designs that ensure safety, regulatory compliance, and operational efficiency from day one — for industrial, commercial, and infrastructure projects.
Electrical design is the foundation on which every safe, efficient, and scalable electrical installation is built. At Enervia Engineering Services, we provide end-to-end electrical design consultancy for new constructions, retrofits, and capacity expansions across industrial plants, commercial buildings, warehouses, hospitals, and infrastructure facilities.
Our design process is rooted in a thorough understanding of your load requirements, operational priorities, and statutory obligations under the Central Electricity Authority (CEA) regulations and IS standards. We produce detailed, construction-ready drawings and documentation that allow your project to move from approval to commissioning without costly rework or compliance delays.
Whether you are an architect coordinating MEP services, a facility owner planning a greenfield factory, or an electrical contractor seeking technical design support, Enervia delivers precise, practically executable designs tailored to your project's budget and timeline.
A comprehensive scope of electrical engineering design deliverables for every project type and scale.
Detailed HT/LT SLD showing power distribution from the incoming supply point to all distribution boards and sub-panels, including protection and metering details.
Floor-plan-based electrical layout drawings covering lighting, power sockets, earthing terminals, conduit routing, and cable tray/trunking paths.
Panel-wise and feeder-wise load schedules, demand factor analysis, and connected/maximum demand calculations to right-size equipment and avoid overloads.
Technical specification and sizing of transformers, switchgear, capacitor banks, UPS, DG sets, MCBs, MCCBs, and ACBs based on load analysis and fault level studies.
Comprehensive earthing and lightning protection design to IS 3043 and IEC standards, including fault current analysis and protection relay coordination.
Preparation of drawings and documentation in the specific format required for TANGEDCO or EB service connection and load sanction approval processes.
A correctly engineered design prevents expensive site-level changes during construction and commissioning — saving time and budget.
All designs are prepared in full accordance with IS standards, CEA regulations, and local electricity board requirements for legal and safe operation.
Right-sized equipment, optimised cable sizing, and power factor correction provisions reduce energy losses and long-term operating costs.
Designs account for planned expansions, additional machinery, and evolving load requirements — giving your facility the flexibility to grow.
Professionally prepared drawings and documentation significantly reduce objections and revision cycles during statutory approval processes.
Our electrical design services are suited for a wide range of project owners and stakeholders.
Factory and plant owners setting up new manufacturing units, expanding production capacity, or relocating facilities across Tamil Nadu.
Real estate developers and builders constructing commercial complexes, malls, office blocks, and mixed-use developments.
Licensed contractors needing engineering drawings and calculations to support project execution and statutory submissions.
Facility managers handling upgrades, additions, or refurbishments who require as-built documentation and updated design support.
Complete HT/LT distribution diagram in PDF and AutoCAD-compatible format.
Floor-plan-based layout for all levels — lighting, power, earthing, and cable routing.
Panel-wise load schedules and a detailed bill of materials to support procurement and costing.
Technical datasheets and sizing justification for all major electrical equipment proposed.
Drawings formatted specifically for TANGEDCO / EB submission, stamped and signed by a licensed electrical engineer.
Documented fault level, short circuit, and protection coordination calculations for technical reference.
