Iranian Gasoline Imports • In 2001, Iran was importing 8.5 million liters of gasoline per day • Gasoline represented more than 85.5% of total petroleum imports • In 2004, Iran was importing 40% of their daily gasoline needs, or 22 million liters of gasoline per day1 • EIA estimates Iran importing 160,000 bpd in 2004 or approximately 25 million liters per day2 • Government paid 2800 rials per liter ($1.19/gal) in 20041 • Approximately $2.5 – $3.0 billion for 20042 • Annual demand increasing at around 9% per year2 • Gasoline imports could potentially cost Iran $4.5 billion for 20053 1- Iran Daily News – 9/28/04, 12/16/04, 2- EIA Country Analysis, 3 - Iran News – 5/10/05 PNNL SA-48454 Iran_Altenergy_PNWCGS_Feb1306.ppt
Iranian Refinery Capacity • Current Iranian refining capacity is 1.47 million BPD • Nine refineries • 240,000 BPD gasoline capacity • Consuming 400,000 BPD gasoline • At current gasoline refining yields (Iran ~ 16% per barrel), a nearly 1,000,000 BPD capacity is required to eliminate 160,000 BPD of gasoline imports. • With 46.7% (Feb. ‘05 U.S. refinery average) yield of gasoline per barrel of oil, require approximately 350,000 BPD additional refinery capacity PNNL SA-48454 Iran_Altenergy_PNWCGS_Feb1306.ppt

Section VI Conclusions of Analysis PNNL SA-48454 Iran_Altenergy_PNWCGS_Feb1306.ppt
Conclusions of Analysis • Iran’s uranium resource is not commensurate with the scale of its declared nuclear program. • Cost of indigenous uranium and fuel production appear substantially greater than market sources. • Front-end (uranium and fuel facilities) do not provide independence. • Indigenous non-nuclear energy resources represent centuries of potential energy supply at current R/P ratios. • Cost of selected front-end nuclear facilities is at least $600 million dollars. PNNL SA-48454 Iran_Altenergy_PNWCGS_Feb1306.ppt
Conclusions of Analysis (2) • Several plausible gas sector projects could be pursued for the cost of the front–end nuclear facility investment. • Gas sector projects involving natural gas treatment plants, CCGT power plants, and supporting pipeline show very attractive rates of return at 18% (23%) over 30 years and a 4.6 (3.2) year payback periods. • Projects which add refinery capacity increase refined product exports, generating billion dollars per year in net revenue. • Approximating the gasoline yield fraction of Iran results in a more attractive refinery project assuming all additional refined products can be exported.
