What a battery can sell

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

Italy 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.

Published checkpoints

Full activation requirement: 30 s · Response checkpoint: 15 s (50% of response) · Response checkpoint: 30 s (100% of response)

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.

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.

Does Italy electricity market have a capacity mechanism?

Italy electricity market has 2 capacity/adequacy arrangements: Italian Capacity Market and MACSE storage capacity procurement. The official sources do not say whether each is a central capacity market.

Italian Capacity Market

operational

Zonal auctions contract de-rated capacity; providers receive a premium and return energy-market revenues above a strike price under reliability-option obligations.

Terna main and adjustment auctions; domestic and foreign-zone price outcomes can differ

Unit of obligation
offer available capacity into dispatching markets and settle strike-price payback obligations
Auction held in 2025
Yes () — Dated from the day the auction ran.

MACSE procures storage energy capacity (MWh) and is separate from the general Capacity Market.

EUR/MW-year capacity premium; new capacity can receive longer agreements

MACSE storage capacity procurement

first auction completed 30 September 2025

Competitive procurement of new storage energy capacity by zone for future delivery, designed to make storage capacity available to market operators under MACSE rules.

Terna zonal auction measured in MWh of storage energy capacity

Unit of obligation
build and make contracted storage capacity available from delivery year under long-term contract rules
Auction held in 2025
No — No capacity auction for this market was found to have been held during 2025 in the sources reviewed.

Not MW of firm capacity and not the Italian Capacity Market.
