Puerto Rico’s Isolated Electric System
• No access to a multi-state transmission system (no access to wholesale power from other regions)
• No access to interstate gas pipelines
• Implications for MATS compliance planning:
• Some of PREPA’s units are “reliability critical”
• Challenges in obtaining access to natural gas
• Challenges in integrating intermittent renewable resources

Compliance: Units 7,8 April 16, 2015; Units 9,10 at least 1st Year Extension Needed • Units 7,8 (200 MW): Limited-Use Status, April 2015 • Units, 9,10 (200 MW): Analyzing options
• Testing to determine possible compliance through operational adjustments • New projects or significant modifications to the existing units (Both require capital
investment and several lengthy approvals) • Siemens System Reliability Study concluded that SJ Units 9 & 10 can be designated as
Limited Use or be retired only if the assumptions regarding the availability of additional generation become true. These assumptions are not expected to be met within the next two years .
