Job description

Overview

Transmission & Interconnection Engineer - Battery Storage. Remote

Plus Power is an energy storage market leader with a 10+ GW portfolio across more than 25 states. Standalone energy storage is transforming North American electric grids, enabling high-penetration renewable energy and balancing intra-hour supply and demand. We seek a data-driven, collaborative professional to help develop, build, and operate assets safely and reliably to decarbonize power markets.

The T&I Engineer will perform interconnection modeling analyses and studies, participate in interconnection scoping meetings and negotiations with third parties and grid authorities, and identify tools to manage costs. The role requires a thorough understanding of requirements to integrate a battery energy storage system (BESS) utility-scale plant into the power grid and its implications on day-to-day grid operations and resource planning.

Responsibilities

• Conduct steady-state power transmission system analysis on TARA or related software to predict network upgrades and mitigation options in various US markets.
• Prepare, submit, and manage generator interconnection processes across ISOs/RTOs.
• Conduct IBR modeling and performance tuning studies using PSCAD and PSSE.
• Develop and validate PSLF, PSS/E, and PSCAD models for BESS generation plants and interconnections, including load flow, dynamic simulations, and reporting.
• Ensure storage resource projects interconnecting to the transmission system meet grid requirements.
• Develop local system EMT models, perform disturbance ride-through simulations, and benchmark PSCAD/PSSE models for system stability and compliance with grid standards.
• Maintain understanding of generation interconnection processes across ISOs/RTOs.
• Provide assistance to other teams on interconnection processes and reactive deficiency analysis.
• Participate in interconnection scoping meetings and negotiations with third parties and grid authorities.
• Perform technical due diligence to determine integration capabilities of electrical grids.
• Provide technical advice on transmission and distribution interconnection issues for various markets.
• Determine cost-effective options for expanding integration capabilities of proposed projects.
• Research utilities and power pools to analyze how their actions affect interconnection processes.
• Assess transmission reliability issues and develop action plans to mitigate interconnection shortfalls.
• Coordinate plans with ISOs to respond to Bulk Power System requirements.

Qualifications

• Minimum BA/BS in electrical engineering; a master's degree and specialization in Power and Energy Systems preferred.
• 2–5 years of professional experience in power and energy industry with focus on electrical systems; renewable energy experience preferred.
• Strong background in power systems, analytical and modeling skills; experience with complex electrical system simulations preferred.
• Proficiency in power system modeling software: PSCAD, PSLF, PSSE.
• Subject matter expertise in one or more organized markets outside ERCOT (e.g., CAISO, SPP, MISO, PJM).
• Experience with inverter-based plant modeling.
• Ability to perform power flow analyses and review models and studies.
• Experience influencing cross-functional teams and strong presentation and writing skills; capable of communicating across regions and languages.
• Ability to engage with customers and stakeholders at all organizational levels.
• Proficiency with Microsoft Office (Word, Excel, PowerPoint).

Compensation, Location, and Benefits

Highly competitive total compensation. Flexible work arrangements (remote or hybrid) from Plus Power’s offices in San Francisco, Houston, Chicago, Seattle, and Palm Beach.

The expected salary range for this position begins at $120,000. Final compensation may be higher or lower based on experience, skills, and other factors. Eligible to participate in annual bonus program.
