Portugal. Status: operational; MARI live from 28 November 2024, aFRR European-product implementation not yet operational in 2025.
Wholesale design: MIBEL/EU-coupled zonal market; replacement reserves use TERRE and mFRR uses MARI; aFRR/PICASSO implementation remained in development during 2025.
Energy in Portugal electricity market trades in 3 layers: day-ahead, intraday and balancing.
Portugal electricity market has 4 ancillary-service products, across 4 families — frequency containment, automatic frequency restoration, manual frequency restoration and replacement reserve: automatic Frequency Restoration Reserve, Frequency Containment Reserve, manual Frequency Restoration Reserve, Replacement 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.

| Frequency containment | ||||
| Frequency Containment Reserve FCRprimary frequency controlprimary reserve symmetric or separate upward/downward according to synchronous area and national procurement operational | Response type automatic, local-frequency-proportional, pre-fault and post-fault containment Trigger continuous response to local frequency deviation; exact deadband and droop are national/synchronous-area technical parameters | Full activation 30 s | Bought national or regional capacity procurement, commonly day-ahead How it settles capacity remuneration or mandatory provision depending on national implementation; energy/imbalance treatment is national Pricing design national/regional rules Counted as a mandatory service, so no volume is bought | |

Who can provide it prequalified generation, storage or demand resources meeting synchronous-area and national TSO requirements Notes from the source Thirty seconds is the Continental Europe full-activation time, not a universal Europe-wide value. Continental Europe requirement for a frequency deviation of at least 200 mHz; do not apply to Nordic FCR products Status of this product Operational in 2025, but not competitively procured Checkpoint recap Full activation 30 s What the source does not state The source states the full-activation requirement. It does not state how long delivery has to be sustained, and the volume is either set per auction or not published as a standing figure — the source does not say which. Sources
