Grid Stor is seeking a Portfolio Manager, Power Markets to own the commercial performance of our operating battery energy storage fleet. This role sits at the nexus between market execution, settlements, and asset performance: ensuring our assets are scheduled and optimized effectively, our revenues are measured and reconciled accurately, and our hedges and bilateral positions are implemented and tracked correctly. The successful candidate will manage execution and optimization of a defined portfolio, coordinating with third-party optimization, our QSE/scheduling counter parties, and internal Operations and Asset Management teams, while building the settlements, performance measurement, and hedge-tracking infrastructure that a growing commercial platform requires.

The role works daily alongside our forecasting, risk, structuring and data teams within the Commercial organization. Must be Central Time-located, preferably Houston or Chicago. Expected time allocation is approximately 40% trading and markets, 20% performance measurement, 20% pricing and structuring, 10% operations coordination, and 10% other commercial support.

• Help develop and enable hedging strategies for the portfolio as markets and capabilities mature, from cash and balance-of-month products out to two-year term horizons, consistent with company risk policies.
• Implement, track, and maintain hedges and bilateral structures in our systems of record, ensuring positions, terms, and exposures are represented accurately.
• Monitor market fundamentals, ISO rule changes, and BESS participation model developments (e.g., real-time co-optimization) and assess commercial impact to the fleet.
• Recommend refinements to bidding parameters and operating strategies based on observed performance, market design knowledge, and BESS technology constraints.
• Establish and maintain the fleet's commercial performance measurement process: realized revenue vs. forecast, performance vs. third-party optimizer benchmarks, and variance attribution.
• Deliver recurring performance reporting to Commercial, Asset Management, and leadership, and drive the continuous-improvement loop back into bidding and dispatch.
• Support Finance in revenue recognition, accrual accuracy, and month-end close for market activities.
• Support evaluation of new hedging, tolling, and bilateral opportunities with pricing analysis, settlement modeling, and exposure quantification, including structuring views on tenor, product, and venue.
• Coordinate hedge settlement mechanics, counter party invoicing inputs, and delivery obligations with Finance and Mid-Office.
• Work with Analytics and the Risk Committee to improve risk metrics and the representation of assets and hedges in management systems.
