One battery, three capacity markets: how much of it counts

Britain, Belgium and Italy pay capacity prices only on the share of a battery they count, and each auction sets that share. In Italy’s auction for delivery year 2028, a new four-hour battery counts for 21% to 51% by zone; one contracted in an earlier auction keeps the 67% set for 2027.

Geography: Great Britain, Belgium, Italy · Procurement rounds covered: GB T-4 2029/30 (closed); BE Y-4 2029-30 (closed); IT 2027 (closed); BE Y-4 2030-31 (closed); IT capacity market, delivery 2028 (open)

Update, : on Italy’s ministry approved revised battery derating factors for the capacity auction with delivery year 2028, after ARERA, the energy regulator, found Terna’s proposal met its criteria on . At two and four hours they are lower in every zone than those approved on , which this note first printed; the section on Italy gives both. Terna has set the auction for .1, 2, 3, 4, 5

Put the same 50 MW, four-hour battery into three capacity auctions and it counts as 21.98 MW in Great Britain’s T-4 for 2029/30, 24.5 MW in Belgium’s Y-4 for 2029-2030, as storage with a daily schedule, and 33.5 MW in Italy’s auction for delivery year 2027, by our arithmetic from each auction’s published derating factor. The derating factor is the share of the battery’s power the market counts on, and the share each market pays its capacity price on: those three auctions set it at 43.96%, 49% and 67%.6, 7, 8, 9, 10, 11, 12, 13

In Italy’s auction for delivery year 2028, a new four-hour battery not already under contract counts at 40% of its power in the North and Centre-North, 51% in the Centre-South and 21% in the South, Calabria, Sicily and Sardinia, so the same 50 MW counts as 20, 25.5 or 10.5 MW, by our arithmetic. In that same auction, a four-hour battery already under contract from an earlier one keeps the 67% that applied for delivery year 2027. The battery has not changed; what Italy counts depends on its auction history and its zone.3, 4, 5, 8

The price is paid on the smaller number

Great Britain’s T-4 auction for 2029/30 cleared at GBP 27.10 per kW a year. Italy’s auction for delivery year 2027 paid every selected offer the marginal premium, capped at the limit for new or existing capacity, rather than its own bid: EUR 47,000 per MW a year, in every area where capacity was awarded. Belgium’s Y-4 auction for 2029-2030 paid each winner its own bid, at a weighted average of EUR 27,333.51 per MW a year.13, 14, 15, 16, 17, 18

Applied to the battery each market actually counted, those prices make its capacity payment GBP 11,913 per megawatt of nameplate a year in Great Britain and EUR 31,490 in Italy, by our calculation, before inflation indexation, payback and penalties.6, 8, 13, 14, 15 The two currencies are not set against each other here. The point is narrower: a bidder who models the headline price alone has modelled the wrong battery. Belgium has no single price to apply: each winner is paid its own bid, on a volume set by its power and its derating factor.12, 17, 18

In Italy’s 2028 auction, a battery’s history sets its count

Batteries were 94.8% of the 594 MW of new derated capacity Italy awarded for delivery year 2027. For the next auction, with delivery year 2028, the technical provisions approved on set factors by zone, in place of the single national factor of 2027, for storage new to that auction: from 54% for a four-hour battery in the Centre-South to 31% in Sicily and Sardinia. Terna then revised the storage values. It used updated estimates of the storage authorised, or expected to be, before that auction, less an estimate of what MACSE, Italy’s separate storage auction, may select for delivery in 2029, and it kept the split by zone. ARERA found the proposal met its criteria and the ministry approved it, for the delivery-2028 auction only.1, 2, 5, 8, 13

Italy, delivery year 2028: derating factor by zone for the batteries the zonal table covers (see below), as approved on 16 Oct 2026 and, superseded, on 6 Aug 2026

Source: Terna, Annex 4 to the technical provisions DTF 2 for delivery year 2028, Table 11: the version approved by ministerial decree no. 327 and the version approved by ministerial decree no. 259.3, 4, 5

Every two- and four-hour value fell, the four-hour value most in the South and Calabria and least in the Centre-South, by our count. Location now moves a new four-hour battery’s factor by 30 percentage points, from 21% to 51%, more than going from two hours to four moves it in any zone, on the same count. ARERA’s own summary is that the revision, other things being equal, reduces what new batteries can be paid if they are contracted through the capacity market.2, 3, 4, 5

The zonal table does not reach every battery. It applies to storage that was not in the offer curve of the delivery-2027 auction and to new storage offered there but not selected. Three groups keep the factors of Annex 3 to the technical provisions: existing capacity in that offer curve, new capacity committed in an earlier auction, and lithium-ion batteries contracted in the MACSE auction for delivery in 2028. Annex 3 holds the values for delivery year 2027, so those batteries count at 67% at four hours and 44% at two, in the same auction where a new one in the South or the islands counts at 21% and 13%. Which factor a battery gets therefore turns on its history in earlier auctions, not on its specification.3, 4, 5, 8

The parameters published for Britain’s T-4 auction for 2030/31 count a four-hour battery at 44.61% and a two-hour one at 22.31%; as of , the government says they may be updated after prequalification and confirmed before the auction in early 2027. Belgium’s Y-4 auction for 2030-2031, whose results Elia published on , counts storage with a daily schedule at 47% at four hours and 29% at two. Set beside those, a new four-hour battery in Italy counts for less than in Britain or Belgium in three of the four zone groups and for more only in the Centre-South, though Italy’s auction delivers in 2028 and theirs in 2030/31 and 2030-2031. None of these comparisons says which market pays better: that also turns on the price each auction clears at.3, 4, 9, 10, 12, 13, 19, 20, 21, 22, 23, 24, 25

What each market takes back, and for how long it pays

A capacity payment is gross income, and what each market takes back differs in kind. Britain penalises a shortfall but has no repayment linked to market prices: a unit that falls short when required pays one twenty-fourth of its price for each megawatt-hour missed, capped at 200% of the month’s share and at the year’s capacity payment.10

Italy has what Britain lacks: whenever the reference price exceeds the strike price, the holder pays Terna the difference on its capacity subject to payback, settlement period by settlement period. Belgium has a payback obligation of the same kind, which applies when the reference price exceeds the strike price. For its 2025 auctions it exempted storage, on condition that an amendment to a royal decree came into force before the bid deadline; it did, on . We have not confirmed whether the rules for later auctions keep that exemption.12, 16, 17, 26

Britain and Belgium offer new build contracts of up to 15 years (15 delivery periods in Belgium) and Italy a 15-year contract, each against an investment threshold: GBP 350 per kW of derated capacity in Britain’s T-4 for 2029/30, EUR 360 per kW of power at the delivery point in Belgium and EUR 215,000 per MW in Italy. Italy gives existing capacity a one-year contract. For 2030/31, Britain’s published threshold is GBP 360 per kW of derated capacity, open to the same update after prequalification. Britain’s and Belgium’s thresholds sit on different bases and Italy’s is given per MW without one, so the three cannot be compared directly. Britain’s base has a further consequence: because the spend is divided by derated capacity, a lower derating factor alone raises the spend per counted kilowatt, so the same investment clears the threshold more easily.10, 16, 19, 20, 21, 27, 28, 29

Who may bid, and when Italy’s window closes

Britain asks for the unit’s legal owner, a future owner or, under conditions, its despatch controller, for a unit in Great Britain or its offshore area with a connection capacity of at least 1 MW, and a certificate of incorporation with a VAT number or notice that there is none yet. Belgium admits legal and natural persons, and new build posts security of EUR 20,000 per MW, or EUR 15,000 once it reaches its permitting milestone. Only companies that own, or hold a mandate without representation for, existing or new capacity at units in Italy connected directly or indirectly to the national transmission grid can take part in Italy’s delivery-2028 auction, subject to further conditions; Terna asks a company registered outside the EU for an affidavit.1, 9, 10, 12, 30

As of , Terna has set Italy’s delivery-2028 auction for , with requests to participate open until , 12:00, under the technical provisions approved on .1

Checklist

  • The derating factor for your battery’s duration and zone, in the auction you bid in, and whether it can still be revised
  • Whether your capacity counts as new to that auction or keeps a factor from an earlier one
  • Whether the price is one clearing price or your own bid
  • The payback or penalty regime, and any exemption for storage with its conditions
  • The contract length open to new build, and the base its investment threshold is measured on
  • Who may apply, the documents required of a company and the security to post

Corrections

  • : This note said that for delivery year 2028 Italy’s four-hour factor ran from 51% in the North and Centre-North to 31% in Sicily and Sardinia, and that location moved it by up to 20 points. In the table approved on the Centre-South value was higher, 54%, so location moved it by up to 23 points. It also left out that the zonal factors apply only to storage that was not existing capacity in the 2027 auction’s offer curve or contracted in an earlier auction. Those values have since been superseded; the update at the top gives the date.
