Cambium

Cambium datasets contain modeled hourly data for a range of possible futures of the U.S. electricity sector through 2050, with metrics designed to be useful for forward-looking analysis and decision support.

Cambium is annually updated and expands on the metrics reported in NREL's Standard Scenarios—another annually released set of projections of how the U.S. electric sector could evolve across a suite of potential futures.

In its fifth annual edition, the 2024 Cambium datasets have been updated to reflect changes in technology, market, and policy as well as improvements to the underlying models.

The 2024 Cambium release includes three products:

• The full 2024 Cambium datasets available for viewing and downloading through NREL's Scenario Viewer
• A workbook (forthcoming) with a subset of Cambium's cost and emissions data, meant to facilitate use by assisting users with levelizing values for their application's timeframe
• An NREL report describing the scenarios, defining metrics and methods, describing major changes since the last release, and discussing intended uses and limitations of the dataset.

Access the Full Datasets

Cambium datasets can be viewed and downloaded via the Cambium projects within NREL's Scenario Viewer.

The Cambium datasets are a companion product to NREL's Standard Scenarios, which contains a broader suite of scenarios with fewer metrics and only at annual temporal resolution. Both products project the possible evolution of the U.S. electricity sector using NREL's publicly available Regional Energy Deployment System (ReEDS) long-term capacity expansion model.
