PGRR 18

• PURPOSE
• Increase the credibility of new generation
  capacity additions considered in the ERCOT models
  used for planning assessments and in the
  calculation of the CDR report.
• Under the present process, counting on proposed
  Generation Resources with only a signed IA can
  negatively impact the planning studies which
  could lead to future reliability problems.
