About this meeting:

Leading up to the 2021 Power Plan Council staff attempted to vet the GENESYS model and the underlying assumptions with stakeholders. Many of the assumptions were locked in early in the planning time period with not enough time to revisit them during the plan. As staff learned more about the actual system operations it became clear that some of those planning assumptions would need to be refined to better represent the hydro system operations on a project-by-project basis. During the late stages 2021 Power Plan, there was limited capability and time to make drastic assumption changes in the model. However, it was deemed valuable during the plan to hold a technical workshop to walk through hydro system on a project-by-project basis with regional stakeholders. Almost all the feedback from stakeholders that could be improved within a short time frame was incorporated before the model was used to check the plan resource strategy. After the plan, an effort was made set aside time to revisit feedback from stakeholders and assumptions in the model on a more holistic basis to better understand limitations and capabilities of the regional hydro system.

On November 3rd 2022, Council staff will be holding a technical conference to update stakeholders on the changes with the underlying assumptions on the hydropower system as represented in the GENESYS model and resulting operational changes.  Since the 2021 Power Plan, staff has focused on improving the simulated hydropower operations by revisiting past assumptions and enhancing the model’s capability. The first part of this project was to document in detail all the known operating limitations and capabilities on the system represented in the GENESYS on a project-by-project basis. The second part was to holistically validate and interpret of the constraints within the context of the GENESYS model. The third part is to vet the revised limitations and capabilities and review the simulated operations from GENESYS with operators, stakeholders and regional experts to prepare the model for the upcoming adequacy assessment and further work.

In addition to comparing simulated and actual operations and high level comparisons to past work, this conference will be an opportunity for a broad group of stakeholders to ask questions of staff, explore model results, assumptions and functionalities and understand more about the GENESYS model before this year’s adequacy assessment.
