We help utilities target and serve their customers more effectively, enhance and optimize their grid, and leverage operating best practices and technologies to manage their business more effectively. Headquartered in Texas, we have 450+ employees across the US and Canada. Learn more at www.esource.com

As a Transmission Planning and Interconnection Study Engineer, you’ll join our grid solutions team as we strengthen reliability, support renewable integration, and advance grid modernization for our clients. You’ll support all aspects of transmission studies, including power flow, voltage stability, transient stability, and other power system analyses. This role is ideal for someone early in their power systems career who has some hands-on experience with tools such as PSS/E, PSLF, or TARA, is eager to learn the interconnection study process, and wants to contribute to work that shapes real-world decisions in the energy industry.

In this role, you will

Perform power system analysis and network modeling to meet client specifications for reliability, regulation, and quality

Conduct studies in areas such as generator connections, voltage stability, arc-flash energy, insulation coordination, and power station design

Prepare detailed technical reports and contribute to technical work products

Collaborate with a global team to execute studies and deliver high-quality solutions

Manage client relationships and expectations, ensuring on-time and within-budget delivery

Contribute to business development activities and identify new client opportunities

You’re likely a great fit if you

Are eager to learn the independent system operator (ISO) cluster interconnection process and transmission stability analysis

Are excited to learn about substation layout, protection, and control

Demonstrate excellent oral and written communication skills

And even better if you

Hold a master’s degree or Ph.D. in power systems engineering

Have PSS/E model development experience and IPLAN and/or Python programming skills

Have PSCAD model development experience

Experience and Skills to Qualify Include

Bachelor’s degree in electrical engineering

Some experience with stability studies using PSS/E, congestion analysis and cost modeling studies, or cluster feasibility studies across one or more independent system operators (ISOs), such as MISO, CAISO, PJM, or SPP

Working knowledge of electric power systems, synchronous generators, motors, power electronic inverters, wind turbines, and solar

Experience with transmission studies on power flow, voltage stability, and other power system analyses

Proficiency with the PSS/E software package, including modules for load-flow, short-circuit, and transient stability analysis; experience with alternative planning software such as TARA, PSLF, DIgSILENT, or DSA Tools is highly desirable

Familiarity with PSCAD and electromagnetic transient (EMT) modeling and simulation

Background in static and dynamic modeling of power system components in PSS/E or DSA Tools, including high-voltage direct current (HVDC), voltage source converters (VSC), static var compensators (SVC), static synchronous compensators (STATCOM), and thyristor-controlled series capacitors (TCSC)

Working knowledge of reliability standards and transmission system interconnection

At E Source, you’ll work alongside people who are thoughtful, curious, and deeply knowledgeable about utility and energy systems. We value clarity over jargon, substance over flash, and collaboration over ego. You’ll have the opportunity to grow your skills, contribute to meaningful work, and help shape a company that plays a real role in how the energy future unfolds.
