Join Our Team as a Power Modeling Engineer Intern!

Are you fascinated by how the electric grid works? Do you enjoy solving complex engineering problems, analyzing data, and building models that influence real-world decisions? If you're looking for an internship where you'll do more than observe—you'll contribute to meaningful work that impacts energy markets across the country—this opportunity is for you.

At The Energy Authority (TEA), our interns are treated as valued members of the team. As a Power Modeling Engineer Intern, you'll work alongside industry experts to develop and enhance power system models, analyze transmission networks, forecast energy prices, and explore the rapidly evolving energy landscape. From renewable generation and battery storage to transmission planning and market optimization, you'll gain hands-on experience solving the kinds of challenges that shape the future of the electric grid.

To maximize your learning and project ownership, interns must be available for a minimum commitment of two semesters (up to one year).

• Work on real projects that directly influence energy market forecasting and decision-making.
• Gain hands-on experience with power system modeling, production cost models, and optimal power flow (OPF).
• Collaborate with experienced engineers and analysts who are passionate about mentoring the next generation of talent.
• Develop highly sought-after technical skills in programming, analytics, and power system simulation.
• Build solutions that improve forecasting accuracy and support strategic decisions for utilities across North America.
• Be part of a collaborative team where curiosity, innovation, and continuous learning are encouraged every day.

• Assist in refining and maintaining network models across multiple energy markets.
• Research and integrate datasets used in optimal power flow (OPF) and production cost modeling.
• Develop and maintain a repository of transmission upgrades to improve network model accuracy.
• Automate simulation schedules and workflows to evaluate system sensitivities more efficiently.

• Evaluate how new generation, battery storage, transmission projects, and large electrical loads influence future energy prices.
• Support the development of standardized reporting for impact studies and modeling results.

• Partner with engineers, analysts, and stakeholders to improve model quality and analytical processes.
• Present findings and technical insights in a clear and meaningful way to both technical and non-technical audiences.

• Pursuing a Bachelor's degree in Electrical Engineering (Power/Energy Systems) or Operations Research.
• Candidates pursuing a Master's degree are strongly encouraged to apply.
• Coursework focused on power systems, optimal power flow, production cost modeling, or energy markets is preferred.

• Experience programming in at least one language such as Python or R.
• Strong analytical and problem-solving abilities.
• Interest in power system modeling, optimization, or energy market analysis.

• PLEXOS
• Dayzer
• PSS®E
• PowerWorld
• PSCAD
• Electric utility internships
• Power system analysis or planning
• Energy market modeling

We're looking for someone who is:

• Naturally curious and eager to learn.
• Analytical with strong attention to detail.
• Comfortable taking ownership of projects from start to finish.
• Able to balance independent work with collaboration.
• An effective communicator who can explain technical concepts clearly.
• Organized, proactive, and committed to delivering high-quality work.

At TEA, you'll gain experience that goes far beyond a typical internship. You'll work on meaningful projects, learn from industry leaders, and develop technical skills that will prepare you for a successful career in the power and energy industry.

If you're excited about solving complex engineering challenges, working with cutting-edge modeling tools, and making a real impact on the future of energy, we'd love to hear from you.

Join us and help model the future of energy.
