Market Products are not used consistently in the CIM because market products are not really consistent across markets...

Energy is the universal commodity; however, even when considering universal grid support products the names vary. In the North America, they call the load frequency control the Regulation product, but in Europe is is Secondary Reserve. Standby/emergency reserve products are more varied. Tertiary Reserve in Europe is split into Synchronous and Non-Synchronous Reserve in the North America. But in even in North America, there is inconsistent usage. PJM calls it Synchronized/Non-Synchronized, MISO and SPP have Spinning and Supplemental, NYISO/ISO-NE/CAISO use Spinning and Non-Spinning, and finally ERCOT has Responsive and Non-Spinning.

One of the oldest market enumerations, MarketProductType does not follow the typical format. We have: EN, RU, RD, SR, NR, RC, LFU, LFD, REG, RPU, CO2e, RMU, and RMD. Changing to Energy, RegulationUp, RegulationDown, SynchronousReserve or SpinningReserve, NonSynchronousReserve or NonSpinningReserve, ReliabibilityUnitCommitment, LoadFollowingUp, LoadFollowingDown, CarbonDioxideEquivalent, RegulationMileageUp, and RegulationMileageDown would break things.

Then we have a similar enumeration: ResourceCapacityType. RU, RD, SR, NR, MO, FO, RA, RMR which map to RegulationUp, RegulationDown, SynchronousReserve or SpinningReserve, NonSynchronousReserve or NonSpinningReserve, MustOffer, FlexibleOffer, ResourceAdequacy, and ReliabilityMustRun. Clearly a different use, but some of the concepts here overlap.

Finally, the most recent is ResourceCertificationKind which allows us to flag when a resource is certified to provide a service. Here the enumeration is properly formatted (all but one entry, that is) and again have a strong correlation to products: RegulationUp, RegulationDown, SpinningReserve, NonSpinningReserve, ReliabilityMustRun, BLACKSTART, DemandSideResponse, SynchronousCondenser, ReliabilityUnitCommittment, Energy, Capacity.
