North American Electric Reliability<br />
Corporation (NERC)<br />
Eastern Interconnect<br />
• ~700,000 MWs interconnected and<br />
operated synchronously.<br />
• Operations and transactions must<br />
be closely coordinated.<br />
• Ability to “lean” on others aids the<br />
reliability of all participants.<br />
• However, distant events can have<br />
widespread impacts.
