State-Level Net Metering Policy Revisions and Solar Rate Impact Analysis

This dataset supports an analysis of the correlation between state-level net metering policy revisions and potential electricity rate impacts from residential solar PV. It covers 44 U.S. states that have offered net metering, with findings indicating estimated rate impacts were below 1% of typical bills in 37 states as of late 2023. The data was produced by the Department of Energy.

Use Cases

• Analyze the relationship between the timing of state net metering policy revisions and the estimated potential rate impacts on customer bills.
• Compare the average and median estimated rate impacts between states that have and have not revised their net metering policies.
• Identify states, such as California and Hawaii, that retained net metering beyond estimated rate impacts of 5% and subsequently revised their policies.
• Examine the deployment levels of residential solar PV in states that have retained net metering despite increased risk of potential rate impacts.

Strengths

• Analysis covers 44 U.S. states that have offered net metering, providing a broad national scope.
• Includes specific findings such as estimated rate impacts being less than 1% of typical bills in 37 states as of late 2023.
• Data is associated with a peer-reviewed article from the Department of Energy, indicating a research foundation.

Limitations

• The specific data columns, row counts, and sample data are unavailable, limiting understanding of the dataset's granular structure.
• The analysis is based on estimates and policy statuses up to the end of 2023, which may not reflect more recent changes.
• The dataset's focus is on correlation analysis, not providing raw underlying time-series or granular state-level data points.

Data was compiled to support a specific research article analyzing state net metering policies and estimated rate impacts.

Time Range

Analysis references data and policy statuses through the end of 2023.

Freshness

The dataset metadata was last updated in March 2026, but the underlying analysis references data through the end of 2023.
