Strategic Petroleum Reserve: DOE Needs to Strengthen Its Approach to Planning the Future of the Emergency Stockpile, Report to Congressional Requesters   [open pdf - 6MB]

"More than 4 decades ago, Congress authorized the creation of the SPR [Strategic Petroleum Reserve] to reduce the impact of disruptions in supplies of petroleum products. DOE [Department of Energy] manages the SPR. As a member of the International Energy Agency, the United States is obligated to maintain reserves equivalent to at least 90 days of the previous year's net imports (imports minus exports). The SPR's storage and related infrastructure is aging, and DOE has plans to modernize these facilities. Since 2015, Congress has mandated crude oil sales. As of March 2018, the SPR held about 665 million barrels of crude oil. GAO [Government Accountability Office] was asked to examine the SPR's ability to meet U.S. energy security needs. This report examines, among other things, the extent to which (1) DOE has identified the optimal size of the SPR, and (2) DOE's plans for modernizing the SPR take into account the effects of congressionally mandated crude oil sales. GAO reviewed DOE's plans and studies, and interviewed agency officials and nine experts selected based on prior work, referrals, and a literature review."
