In
eMKT there is a calculator tab that can be used to estimate two types of opportunity costs:
Energy Market Opportunity Cost (EMOC) and Non-Regulatory Opportunity Cost (NROC). A generating unit may be eligible to add opportunity cost to the cost-based incremental energy offer if it falls into one of three categories:
- The unit has an externally imposed environmental limit on run hours within a certain compliance period (EMOC)
- The unit has a force majeure fuel limitation and is limited in run hours for a particular definable period (NROC)
- The unit has a physical equipment limitation on run hours due to Original Equipment Manufacturing (OEM) recommendations or insurance carrier restrictions (NROC)
For further information on whether a unit is eligible for EMOC or NROC please see the
PJM Open Access Transmission Tariff (OATT) and
PJM Manual 15: Cost Development Guidelines.
The
eMKT Opportunity Cost Calculator was updated on January 24, 2012 from version 1 to version 2 which expanded the capabilities of the calculator. Using the calculator does NOT affect unit offers into PJM in any way; the results can be reviewed by unit owners for estimation and (if they meet all criteria) in the incremental energy offer. For more information about the changes, please see issue tracking for
Energy Market Opportunity Cost and
Non-Regulatory Opportunity Cost.
