A bill to require the Secretary of Energy to conduct a study and submit a report on national resource adequacy, and for other purposes.

AI-Generated Summary

Updated January 20, 2026 at 3:43 PM UTC

The bill directs the Secretary of Energy to conduct a comprehensive study of the nation’s electricity resource adequacy and to submit a report to Congress. The study must examine how recent and planned retirements of baseload generation, the need for peaking capacity, the variability of renewable sources, and future demand scenarios—including climate change, decarbonization, and economic factors—affect the ability to meet electricity demand. The Secretary must deliver the findings and recommendations within 180 days of enactment. The goal is to give policymakers data to ensure sufficient reliable power supply.

Key Provisions

Define “resource adequacy” as the ability of supply‑side and demand‑side resources to meet total electricity demand, including losses.
Require the Secretary of Energy to study how recent baseload retirements have changed firm capacity across regional grids.
Require analysis of planned baseload retirements, peaking capacity needs, and potential energy shortfalls.
Require assessment of how variable generation and forecasting errors affect capacity accreditation.
Require projection of a range of future electricity demand trajectories considering climate change, decarbonization, and economic factors, and evaluate whether additional firm capacity or interregional transmission is needed.
Require evaluation of whether variable generation combined with technical and non‑technical solutions can meet future demand.
Mandate submission of a report with study results and congressional recommendations no later than 180 days after enactment, to the Senate Energy and Natural Resources Committee and the House Energy and Commerce Committee.

Mr. Speaker, today I rise to thank President Joseph R. Biden, Jr. for his proclamation pursuant to the Antiquities Act of 1906 expanding the Berryessa Snow Mountain National Monument. I also thank Secretary of the Interior Deb Haaland, U.S. Senator Alex Padilla (D- CA), Congressman Mike Thompson (D-CA04), and the Yocha Dehe Wintun Nation for their support in conserving this special place forever.

President Biden's proclamation expands the Berryessa Snow Mountain National Monument to include approximately 13,696 additional acres of federally owned public land in Lake and Colusa Counties, California, encompassing the entirety of the Molok Luyuk region within the Monument. Second, it directs the federal Bureau of Land Management and the U.S. Forest Service to improve tribal co-management of the Berryessa Snow Mountain National Monument. Third, it renames the former Walker Ridge tract to ``Molok Luyuk,'' meaning Condor Ridge in the Patwin language of the Yocha Dehe and other Native American tribes indigenous to the area.

I am thrilled that President Biden issued this presidential proclamation to preserve the tribal wisdom, heritage, and cultural traditions that Molok Luyuk has been home to for over 11,000 years. This expansion follows years of advocacy by me, Congressman Thompson, Senator Padilla; federal, tribal, and local officials representing Northern California; and nongovernmental organizations, including environmental conservation, public access, outdoor recreation, and off- highway vehicle groups.

In July 2015, President Obama issued Presidential Proclamation 9298, establishing the Berryessa Snow Mountain National Monument. This set the boundary as federal land surrounding the Lake Berryessa reservoir but omitted Molok Luyuk in Lake and Colusa Counties. My legislation (H.R.761/S.393) in the 114th Congress with then-U.S. Senator Barbara Boxer (D-CA) and Congressman Thompson to establish the National Monument would have included Molok Luyuk within the boundary.

In the 117th Congress, at the behest of Woodland, California-based Tuleyome, a nonprofit conservation advocacy organization co-founded by my former constituent Bob Schneider in 2002, I introduced the ``Berryessa Snow Mountain National Monument Expansion Act'' (H.R.6366/ S.4080) with Senator Padilla and Congressman Thompson. I and other members of California's Congressional delegation then called on President Biden to use his authority under the Antiquities Act of 1906 to expand the Berryessa Snow Mountain National Monument and provide opportunities for federally recognized tribes like the Yocha Dehe to engage in voluntary co-management with the relevant federal land management agencies. We also called on Secretary Deb Haaland to order the U.S. Board on Geographic Names to officially rename Walker Ridge to Molok Luyuk. On May 2, 2024, I joined the President in the Oval Office with Secretary Haaland for a signing ceremony granting our requests.

Conserving California's special places has been a lifelong passion throughout my tenure in the state legislature, as Deputy Secretary of the Interior during the Clinton Administration, and now as a Member of Congress. Molok Luyuk is one of those special places. It was a privilege to represent Lake and Colusa Counties as the U.S. Representative for California's Third Congressional District from 2013 to 2023, and I am honored to have played a leading role in expanding the Berryessa Snow Mountain National Monument to preserve Molok Luyuk's ecological diversity and tribal heritage for future generations.

Lastly, I want to thank my former Legislative Assistant, Mr. Tigran Agdaian, and my former Knauss Fellows, Mr. Sean Mullin and Mr. Jeffrey Beauvais, for their important role in developing this legislation while on my staff.

President Biden's expansion of the Berryessa Snow Mountain National Monument honors the Patwin Tribes who walked this land long before our country was founded. On behalf of California's Congressional delegation, I thank the President.

2d Session

S. 4080

IN THE SENATE OF THE UNITED STATES

April 9, 2024

Mr. Braun (for himself and Mr. Scott of Florida) introduced the following bill; which was read twice and referred to the Committee on Energy and Natural Resources

A BILL

To require the Secretary of Energy to conduct a study and submit a report on national resource adequacy, and for other purposes.

Study and report on national resource adequacy

(a)

Definitions

In this section:

(1)

Resource adequacy

The term resource adequacy means the ability of supply-side and demand-side resources to meet aggregate electricity demand (including losses).

(2)

Secretary

The term Secretary means the Secretary of Energy.

(b)

Study

The Secretary shall conduct a comprehensive study on national resource adequacy to determine—

(1)

how recent retirements of baseload electric generation have affected the regional firm capacity available for all regional electric grids;

(2)

the effects that planned retirements of baseload electric generation and the increased need for peaking capacity have or would have on energy shortfalls;

(3)

how the variable nature of certain sources of energy production and forecasting errors may impact resource adequacy and capacity accreditation;

(4)

(A)

a range of potential future electricity demand trajectories that captures the uncertainty represented by a changing climate, decarbonization, and macroeconomic factors; and

(B)

whether that future electricity demand requires increasing firm capacity or interregional transmission to load match with regional peak power demand during all hours of the year; and

(5)

the extent to which variable generation technologies in concert with other technical and nontechnical solutions can provide adequate capacity to meet a range of potential future electricity demand trajectories.

(c)

Report

Not later than 180 days after the date of enactment of this Act, the Secretary shall submit to the Committee on Energy and Natural Resources of the Senate and the Committee on Energy and Commerce of the House of Representatives a report describing the results of the study conducted under subsection (b), including recommendations for Congress to ensure that the United States maintains necessary resource adequacy to meet forecasted demand.
