Substations - Design Engineer

Urban Ridge Supplies

Key Responsibilities:

• Prepare and review engineering deliverables for HV/MV substations associated with large-scale solar PV plants, including single line diagrams, general arrangement layouts, sections, elevations, grounding drawings, and lightning protection layouts.

• Perform and check key electrical design calculations, including grounding/earthing studies, lightning protection, cable sizing, voltage drop, short-circuit calculations, auxiliary load calculations, and equipment sizing.

• Prepare and review technical specifications, equipment datasheets, BOQs, and material requisitions for substation systems.

• Support the design and selection of major substation equipment such as power transformers, GIS/AIS switchgear, circuit breakers, disconnectors, CTs, VTs, surge arresters, harmonic filters, shunt reactors/capacitor banks, and reactive power compensation equipment.

• Review vendor drawings, calculations, and technical submittals to ensure compliance with project requirements, grid code obligations, utility standards, and applicable international standards.

• Coordinate closely with solar plant design, grid interconnection, civil, structural, mechanical, protection, control, SCADA, and construction teams to ensure smooth interface management and integrated design delivery.

• Ensure designs comply with IEC, IEEE, ANSI, utility requirements, local regulations, and client specifications.

• Support project execution through design reviews, technical meetings, procurement support, site queries, construction clarifications, factory acceptance support, and commissioning assistance.

• Review or support secondary engineering deliverables such as control schematics, cable schedules, interconnection diagrams, panel layouts, and interface drawings to ensure full alignment between primary and secondary systems.

• Contribute to the standardization of substation design approaches across multiple giga-scale PV projects to improve quality, constructability, repeatability, and delivery efficiency.

Required Qualifications:

• Bachelor s degree in Electrical Engineering.

• 4 8 years of experience in substation design engineering.

• Proven experience in HV/MV substation projects within utility, renewable energy, EPC, industrial, or consulting environments.

• Experience supporting substations for utility-scale solar PV, renewable interconnection, or power infrastructure projects is strongly preferred.

• Familiarity with grid interconnection requirements and utility coordination for large renewable projects is an advantage.

• Good working knowledge of relevant standards including IEC, IEEE, ANSI, and utility-specific requirements.

• Strong coordination, communication, and technical review skills.

Preferred Profile:

• Experience working on multiple substations across large renewable portfolios.

• Exposure to reactive power compensation, collector substations, and transmission interconnection design.

• Ability to work in multidisciplinary teams and manage parallel deliverables across fast-track projects.

• Detail-oriented, practical, and focused on delivering high-quality designs that are both technically robust and constructible.
