More than a career - a chance to make a difference in people's lives.

Build an exciting, rewarding career with us – help us make a difference for millions of people every day. Consider joining the Duke Energy team, where you'll find a friendly work environment, opportunities for growth and development, recognition for your work, and competitive pay and benefits.

The Engineer I position is the entry level of the Engineering classification hierarchy. Employees in the Engineer I position solve problems in engineering areas of specialization with close supervision. An Engineer I is expected to develop skills and the ability to work with greater independence. An Engineer I is expected to have knowledge of fundamental concepts of electric power systems.

This position will develop engineering and technical skills to support various Duke Energy internal groups in pursuit of self-developing battery energy storage and microgrid projects. Applicants are expected to have engineering skills related to power system modeling and analysis of distribution and/or transmission electric systems and understand inverter-based resources (IBR) such as battery energy storage systems (BESS) and microgrids but also have familiarity with other renewable technology such as solar.

This position will:

· Provide engineering support to technical matters throughout the development process with a heavy focus on BESS and microgrid siting analysis and design, power system modeling, and integration of distributed energy technologies in Duke Energy regulated jurisdictions.

· Utilize knowledge of BESS and microgrid project engineering, electric generating facilities, utility interconnection requirements, inverter/plant control, metering schemes, and power system steady state analysis to evaluate, identify, and mitigate technical risks associated with proposed project designs.

· Provide engineering support through detailed design, construction, and commissioning of distribution-connected and transmission-connected battery energy storage projects.

· Develop performance testing criteria and evaluate test results during site commissioning.

· Provide IBR site model support that includes but is not limited to: transmission and distribution steady state analysis, dynamic studies, and EMT analysis for all BESS sites.

This position must work collaboratively with key internal stakeholders, including Project Management and Construction (PMC), Supply Chain, Transmission, Distribution, Generation, IT, Interconnection, and Health & Safety among others. The position will also require working with third-party consultants, equipment vendors, system integrators, and Engineering Procurement and Construction (EPC) firms.

Responsibilities

Responsibilities and duties include, but are not limited to:

· Support greenfield and brownfield development through site screening and selection, system feasibility studies, preliminary design, cost estimates, and overall technical due diligence.

· Perform power system modeling and analysis utilizing tools such as PSSE/TARA, CYME, CYMCAP, PSCAD, ETAP, and MATLAB.

· Perform battery facility design including but not limited to power and energy sizing, electrical single-line diagrams, and equipment selection. Also, design preliminary physical site layout and site access, while adhering to jurisdictional guidelines, industry best practices, and internal company standards.

· Create and submit interconnection requests for distribution and transmission connected projects and analyze study results.

· Provide technical support and analysis of studies such as conductor ampacity, capacity testing, reactive power studies, harmonic analysis, and system protection studies.

· Work with Supply Chain on developing technical packages and requirements for issuing Requests for Proposals (RFP) for EPC and key equipment.

· Support efforts to optimize BESS systems design and output.

· Analyze degradation impacts for future BESS, in-service BESS, and for future expected dispatch.

· Prepare thorough and accurate technical reports, correspondence, documentation, calculations, and design plans related to projects and analysis of increasing scope and complexity.

· Stay informed of technology advancements, market trends, best practices, and relevant guidelines and standards related to energy storage technology.

· Maintain equipment supplier relationships and advise Supply Chain and PMC on energy storage technology trends.

· Travel required for supporting projects (approximately 10%).

Key skills and experience:

· Power system modeling utilizing tools such as PSSE/TARA, CYME, PSCAD, ETAP, and MATLAB.

· Coursework in power systems analysis, power electronics, drive/converter controls, and/or fault analysis.

Minimum Qualifications

· Must have obtained Bachelor of Science in Electrical Engineering with power system, controls, or power electronics focus from an ABET accredited program.

· A master’s degree in Electrical Engineering will be considered in lieu of the B.S. Electrical Engineering degree.

Desired Qualifications

· Master’s and/or PhD in engineering.

· Knowledge of generation interconnection requirements.

· Knowledge of power system analysis.

· Experience in the electric utility industry.

· Experience with transient stability studies, dynamic modeling, power electronics, or converter controls.

· Working experience with software and programming such as Python, Simulink, SQL, and Pi Historian.

· Ability to deal with a variety of individuals from various socio-economic, cultural, and ethnic backgrounds.

· Strong project management, organizational, and problem-solving skills.

· Ability to work with diverse teams with different backgrounds and personalities.

· Ability to collect and organize data, and apply procedures, read and comprehend technical drawings, graphs, maps, and other technical documents.
