- Current generating unit operating status
- Constraints on the minimum up and down time of the generators
- Generation and start up bid prices
- Plant-related startup and shutdown constraints
- Minimum and maximum generation constraints
- Generation and reserve requirements
- Transmission facility maintenance schedules
- Transmission constraints
- Phase angle regulator settings
- Transaction bids
- Minimum and Maximum Energy Level constraints (for Energy Storage Resources (ESR) only)
- Bid Beginning Energy Level for ESR (for ISO Managed ESR only)
- Co-located Storage Resources (CSR) Scheduling Limits (Only for solar/wind Intermittent Power Resource (IPR) and ESR Generators that participate in a CSR). Aggregations comprised of ESR, Wind, or Solar only are not eligible to participate in a CSR.
