Oman (Main Interconnected System). Status: operational.
Wholesale design: A half-hourly day-ahead spot market has operated in the MIS since 1 January 2022 alongside long-term power purchase agreements and the single-buyer procurement model.
Oman Main Interconnected System spot market has 5 ancillary-service products, across 5 families — frequency containment, automatic frequency restoration, replacement reserve, reactive power & voltage and black start & restoration: Black Start, Primary Response, Reactive Power / Voltage Control, Secondary Response, Tertiary Reserve. Response timing, direction and eligibility for each are in the table below; a product's full record lists the official sources behind it.
Every value below comes from the official sources listed in that product's full record. Most products cite more than one, and the published sources do not say which of them states each individual value, so the binding is to the product's record rather than to a single document. A missing line means the source does not state that value — never that the value is zero.

| Service | How it activates | Response | Sustained delivery | Procurement |
|---|---|---|---|---|
| Frequency containment | ||||
| Primary Response symmetric operational | Response type post-fault; automatic local Trigger Frequency deviation; normal system frequency band is not treated as the product activation threshold. | Full activation 5 s | As the source describes it Full by t=5 seconds and sustainable until at least t=30 seconds from the event; t=30 is an event-time endpoint, not an additional 30-second duration | Varies System-operator determined Bought Operational availability under Grid Code/PPA obligations Through mandatory provision; bilateral contract Pricing design Grid Code and contract terms |

What the source says about timing Fully available within 5 seconds Who can provide it Generating units and other facilities meeting Grid Code requirements. Checkpoint recap Full activation 5 s Sources | ||||
| Automatic frequency restoration | ||||
| Secondary Response symmetric operational | Response type post-fault; automatic central Trigger System-control signal following frequency deviation. | Full activation 30 s | As the source describes it Full by t=30 seconds and sustainable until t=30 minutes from the Grid Code event/activation origin; not an additional 1,800-second duration | Varies System-operator determined Bought Operational availability under Grid Code/PPA obligations Through mandatory provision; bilateral contract Pricing design Grid Code and contract terms |
Full record for Secondary Response — document bound, page for these figures not recorded What it is for Restore frequency and replace primary response following an imbalance. What the source says about timing Fully available within 30 seconds Who can provide it Generating units and other facilities meeting Grid Code requirements. Checkpoint recap Full activation 30 s Sources | ||||
| Replacement reserve | ||||
| Tertiary Reserve up operational | Response type manual Trigger System-operator instruction. | Full activation 30 min | Varies System-operator determined Bought Operational availability under Grid Code/PPA obligations Through mandatory provision; bilateral contract Pricing design Grid Code and contract terms | |
Full record for Tertiary Reserve — document bound, page for these figures not recorded What it is for Replace secondary response and restore reserve capability. What the source says about timing Available within 30 minutes Who can provide it Synchronized, non-synchronized and demand-reduction resources meeting Grid Code requirements. Checkpoint recap Full activation 30 min What the source does not state The source states the full-activation requirement and a procurement volume in its own words. It does not state how long delivery has to be sustained. Sources | ||||
| Reactive power & voltage | ||||
| Reactive Power / Voltage Control non-directional operational | Response type continuous; automatic local; manual Trigger Voltage setpoints and system-operator instruction. | Stated response Equipment- and instruction-specific | As the source describes it Continuous/as required | As stated Network-study-specific Bought Continuous/operational Through mandatory provision; bilateral contract Pricing design Grid Code and contract terms |
Full record for Reactive Power / Voltage Control — document bound, page for these figures not recorded What it is for Maintain system voltages using reactive-power capability and voltage control. Who can provide it Generators and reactive compensation equipment meeting Grid Code requirements. Sources | ||||
| Black start & restoration | ||||
| Black Start operational | Response type post-fault; manual; event-triggered Trigger Restoration plan. | Stated response Facility- and restoration-plan-specific | As the source describes it Restoration-plan-specific | As stated Restoration-plan-specific Bought Contracted/assigned by restoration need Through bilateral contract; administrative assignment Pricing design Contract terms |

No. Oman Main Interconnected System spot market's capacity/adequacy arrangement: No standalone capacity market. Responsibility sits with Nama Power and Water Procurement.
not applicable
Long-term adequacy is procured through competitive IPP/PPA tenders by the single buyer, rather than a separate capacity-market auction.
