The NREL Standard Scenarios product is a suite of forward-looking power sector scenarios that NREL projects use in its long-term capacity expansion model (ReEDS) and its market penetration model (dGen).
The scenarios encompass earth system feedbacks, electricity demand growth, electricity generation, existing fleet retirements, fuel prices, the policy and regulatory environment, resource and system constraints, and technology costs. Together, they make possible the transparent and quantitative examination of how various inputs impact the development of the power sector. Moreover, they provide the context and data to not only understand changes in the U.S. power sector but also inform stakeholder decision making regarding its future direction.
The scenarios, which are updated each year along with the ATB, include technology cost and performance assumptions from the ATB.
Scenario analyses are an integral part of any integrated technology analysis portfolio and are used to inform long-term R&D strategies. Transparent, harmonized assumptions are required for scenario analysis to inform these strategies. Technology cost and performance data-both current and future-are critical drivers of future deployment of electricity generation technologies.
With the increasing reliance of so much energy analysis on its data and modeling tools, NREL developed its Standard Scenarios and ATB products to be the consistent underlying data and assumptions on which such analysis can be based. Together, NREL's Standard Scenarios and ATB are specifically intended to:
The seminal analyses reported in the following publications, which all required technology cost and performance assumptions, motivated NREL to create the ATB to lend consistency to the analyses.
In 2017, when NREL released an ensemble of standard modeling scenarios for the future, it published a second report summarizing an analysis based on the scenario results. Specifically, the 2017 Standard Scenarios Report: A U.S. Electricity Sector Outlookexplores four key themes in the U.S. power sector:
Scenario results from the Standard Scenarios are accessible via the Standard Scenarios Results Viewer.
