Core Responsibilities

Primary Functions

Develop and execute short-term, medium-term, and long-term hydro generation schedules to optimize portfolio value while respecting operational, environmental, and contractual constraints.
Create, validate, and run complex hydro-optimization models (e.g., using Plexos, GAMS, or proprietary software) to determine the most profitable dispatch of hydro resources in day-ahead and real-time energy markets.
Generate and analyze short-term and long-range hydrological forecasts for streamflow and reservoir inflows, utilizing statistical models, meteorological data, and snowpack information.
Formulate and communicate bidding strategies for hydro assets in wholesale electricity markets, considering ancillary services, capacity, and energy market products.
Monitor and manage reservoir elevations, river flows, and spill requirements to ensure strict compliance with federal operating licenses, water rights, and environmental regulations.
Conduct detailed post-analysis of hydro system performance, comparing planned versus actual operations to identify opportunities for model refinement and strategy improvement.
Perform stochastic analysis to understand and quantify the financial risks and opportunities associated with hydrological variability and market price volatility.
Develop and maintain comprehensive datasets related to hydrology, plant operations, market prices, and weather, ensuring data integrity and accessibility.
Collaborate closely with real-time traders and system operators to provide generation guidance and adjust plans based on evolving grid conditions and market dynamics.
Prepare and present clear, concise reports and visualizations on hydro system status, planned operations, and financial performance to senior management and commercial teams.
Model and evaluate the impacts of potential outages, maintenance schedules, and capital projects on hydro generation capacity and overall portfolio value.
Support long-term resource planning by providing expert analysis on future hydro capabilities, climate change impacts, and potential new asset integrations.
Analyze and interpret complex environmental regulations, such as those related to fish passage, water temperature, and dissolved gas, translating them into operational model constraints.
Conduct fundamental analysis of power and gas markets to inform hydro scheduling decisions and hedging strategies.
Develop and maintain shadow models and analytical tools (often in Python or R) to validate primary optimization software and perform specialized "what-if" scenarios.
Serve as the subject matter expert on the company's hydro system capabilities and constraints during cross-functional projects and regulatory discussions.
Evaluate the economic trade-offs between competing water uses, such as power generation, flood control, recreation, and irrigation.
Continuously research and implement new modeling techniques, forecasting methods, and optimization algorithms to enhance the sophistication of the planning process.
Act as a key liaison between the commercial trading floor, plant engineering staff, and environmental compliance teams to ensure aligned and informed decision-making.
Provide analytical support for contract negotiations and settlements related to water or power sales agreements.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis for various internal stakeholders, including risk management and corporate strategy.
Contribute to the organization's broader data strategy and roadmap by identifying needs for new data sources or analytical platforms.
Collaborate with IT and data engineering teams to translate evolving business needs into technical requirements for data pipelines and modeling environments.
Participate in sprint planning, retrospectives, and other agile ceremonies as part of a data-driven commercial team.
Mentor junior analysts and interns, providing guidance on analytical techniques and business context.
Document modeling methodologies, data sources, and business processes to ensure continuity and knowledge transfer.
