Company Overview

Plus Power is an energy storage market leader, with a market-leading 10+ GW portfolio across more than 25 US states and Canadian provinces that will transform North American electric grids into cleaner and more versatile critical infrastructure.

Standalone energy storage is rapidly transforming the North American energy markets, because it is cheaper than new natural gas plants, faster to build than fossil peakers or transmission, and able to perform diverse energy services. Plus Power partners with electricity system operators, utilities, and investors to originate, develop, finance, own and operate standalone energy storage projects that provide critical services to the wholesale electric market. Plus Power’s team applies an intentional mindset to energy storage development by using a data-driven approach to development and operations.

At Plus Power, we are focused on solving hard climate problems, profitably. We are growing fast, and value candidates who, like us, share a focus on setting high expectations, owning and learning from mistakes in the spirit of radical transparency, and are committed to internal partnering as a key element of our ideas meritocracy.

The T&I Engineer will also identify and develop tools for managing and reducing costs and p rovide technical solutions to address specific transmission and distribution grid requirements for various markets .

Responsibilities

• Conduct steady state power transmission system analysis on TARA or related software to predict network upgrades and find ways to mitigate them in various US markets.
• Prepare, submit, and manage generator interconnection process across ISOs/RTOs.
• Conduct IBR modeling and performance tuning studies using both 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 that storage resource projects interconnecting to the transmission system meet grid requirements.
• Develop local system EMT models, perform disturbance ride-through simulations, and conduct PSCAD/PSSE model benchmarking to ensure system stability and compliance with grid performance standards.
• Maintain a thorough understanding of the generation interconnection process across ISOs/RTOs
• Provide assistance to other functional teams on various project activities related to interconnection process and reactive deficiency analysis
