AES Clean Energy (AES) is seeking a Transmission Strategy SR Manager for the ERCOT region, and possibly additional markets, to join our Transmission Strategy team. This role is responsible for both transmission planning and nodal production cost modeling.

AES is at the forefront of technical and strategic innovation. This team is central to continuing our industry leadership as one of the largest U.S. Independent Clean Power Producers, across Solar, Wind, and Storage.

This ERCOT SR Manager, Transmission Strategy role, will serve as the principal Transmission Strategy lead for ERCOT, and possibly additional continental US energy markets.

The Transmission Strategy team is responsible for setting a transmission focused market-wide strategy in all Continental U.S. energy markets, and integrating that strategy across AES teams, including Development, Commercial, and Execution teams, partnering with Development, Commercial, and Execution teams to apply transmission strategy at the project level. This strategy will be applied to prioritizing our greenfield efforts, prioritizing our project acquisition efforts, and prioritizing our existing project pipeline. The Transmission Strategy team is also responsible for facilitating transmission strategies in certain RTOs and with particular projects, project specific assessment of network impacts, and deliverability risks and opportunities.

This function is critical through all stages of development, from greenfield prospecting through late-stage interconnection studies and agreement execution.

• Familiarity with basic concepts in short circuit and stability analysis is beneficial.
• Demonstrated experience personally running nodal production cost models with at least one of the industry-accepted tools (i.e., PROMOD, UPLAN, GE MAPS, Aurora) is required. Strong knowledge of power system economics including dispatch trends, curtailment trends, and locational marginal pricing trends is preferred.
• Experience with FERC/ISO/RTO/TO Transmission Planning and Generation Interconnection processes required. Experience with reviewing and negotiating Transmission Services Agreements (TSAs) preferred. Experience with assessing strategies for wheeling across balancing authorities is beneficial.
• Experience with renewable energy development is beneficial.
• Ability to create a positive and productive teamwork environment.
• Ability to communicate effectively in both commercial and technical venues. Ability to present complex technical content in a simplified and useful manner for a non-technical audience.
• Ability to innovate and resolve complex challenges.
• Willingness to travel as needed, which is not expected to exceed 10% of the time.
