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.

Responsibilities

• 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.

Requirements

• 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.

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.

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%).

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
