Job description

About us

TAaKA Engineering is a Tokyo-based engineering consulting company that specializes in prime power, dispatchable power, gas, data centers, and commercial and industrial energy projects in the U.S. Our current portfolio predominantly consists of solar projects, but we are expanding our expertise to include microgrids and data center infrastructure. With a focus on innovation and sustainability, we aim to revolutionize the energy engineering landscape. 

Role Overview:

The Power Plant Lead Electrical Engineer will be responsible for conceptual design, system architecture, and feasibility studies for the electrical infrastructure of power generation systems that integrate gas turbines, PV solar, BESS, and other technologies to meet the unique energy demands of large industrial facilities and data centers.

The role balances FEED-level conceptual design with hands-on electrical system simulation (ETAP, DIgSILENT, CYME, PSS, SKM, or equivalent) to validate performance, reliability, and availability. The engineer will work closely with mechanical, civil, and controls teams to deliver fully integrated, reliable, and cost-optimized power solutions.

 

Key Responsibilities:

Conceptual Electrical System Design:

  • Develop preliminary single-line diagrams (SLDs), electrical layouts, and system architectures for gas turbines, solar PV, and battery energy storage systems (BESS).

  • Define HV/MV power distribution strategies, interconnection schemes, and redundancy concepts.

  • Perform detailed simulations including load flow, short-circuit, stability, motor starting, arc-flash, and harmonic studies using ETAP, DIgSILENT, CYME, PSS, SKM, or equivalent.

  • Model and assess system reliability and power availability (N-1/N-2 contingency, redundancy analysis) using reliability block diagrams and probabilistic methods.

Grid Connection & Compliance:

  • Evaluate grid interconnection requirements and compliance with international electrical standards.

  • Assess reactive power compensation, harmonics, and stability impacts for seamless system integration.

  • Define protective relays and power system protection strategies for reliability and safety.

Equipment Selection & Preliminary Specifications:

  • Identify key electrical components, including circuit breakers, relays, inverters, transformers, cables, and grounding systems.

  • Develop preliminary equipment specifications and define procurement strategies for major electrical assets.

Reliability & Availability Analysis

  • Quantify system uptime and availability targets (e.g., 99.999% for data centers).

  • Compare alternative configurations (radial, ring bus, dual-bus, UPS/BESS) for reliability and cost.

Interdisciplinary Coordination & Documentation:

  • Work closely with civil, mechanical, and control engineers to integrate electrical systems with plant infrastructure.

  • Manage external engineering consultants to produce technical studies and design deliverables

  • Coordinate with other engineering teams (USA, South Korea, Vietnam) and provide necessary technical support in electrical design and engineering tasks.

  • Provide technical input for CAPEX/OPEX estimation and feasibility studies.

  • Prepare FEED-level reports, electrical schematics, and technical documentation for the next project phase.
