What a battery can sell

What ancillary services can a battery sell in Türkiye electricity market?

Türkiye electricity market has 9 ancillary-service products, across 6 families — regulation, frequency containment, automatic frequency restoration, reactive power & voltage, black start & restoration and other services: Black Start and System Restoration, Balancing Power Market Down-Regulation, Balancing Power Market Up-Regulation, Demand-Side Participation Service, Instantaneous Demand Control, Primary Frequency Control, Reactive Power Support, Regional Capacity Leasing, and 1 more. 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.
