What a battery can sell

What ancillary services can a battery sell in Mercado Eléctrico Mayorista (Argentina SADI)?

Mercado Eléctrico Mayorista (Argentina SADI) has 5 ancillary-service products, across 4 families — frequency containment, automatic frequency restoration, contingency reserve and replacement reserve: Reserva de 10 minutos, Reserva de 20 minutos, Reserva de 5 minutos, Reserva para Regulación Primaria de Frecuencia, Reserva para Regulación Secundaria de Frecuencia. 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.
