Tesla Energy has signed a framework agreement to supply about 3 GWh of Megapack battery storage for projects in Italy, in a deal announced on 10 September 2026 by the developer Zhero and the South African independent power producer H1 Holdings.
What was actually agreed
A framework agreement is not a purchase order, and the distinction matters here. The parties describe roughly 3 GWh of storage capacity in total, of which the first tranche is 200 MW of shovel-ready plants — sites with permits and grid connections already in hand. The remainder depends on Zhero's wider pipeline, which the company puts at more than 1.5 GW of utility-scale storage in development.

Neither company disclosed a contract value. A figure of roughly €800 million has circulated in secondary coverage, but it does not appear in either company's statement and should be treated as unconfirmed.
Why Italy, and why now
The interesting part is how these projects intend to earn money. Italian grid-scale storage has largely been built against MACSE, the state-run capacity auction that underwrites storage revenue. Zhero says these plants will instead be backed by long-term purchase agreements, which it frames as reducing reliance on regulated support.
That is a bet that Italian storage can stand on merchant and contracted revenue rather than a subsidy mechanism. Daniele Moriconi, who heads Zhero's battery storage division, put the company's own stake plainly: the agreement marks "a pivotal step in the transformation we have anticipated from the start: evolving from mere developers into true owners and operators."
Where it sits in Tesla's European energy business
Tesla Energy has been the quieter half of the company's European story, and the larger one by growth. This is not its biggest Italian commitment — in June 2026 Tesla signed for 25 GWh with NatPower across Italy and the United Kingdom, which remains its largest European Megapack deal. Three GWh is roughly an eighth of that, and it lands in the same market.
Two of these deals inside four months in one country is the signal. Italy has a high share of solar on a long, weak grid, and storage is what makes that combination workable — the same structural reason Tesla has been able to sell Megapacks faster than it can sell cars in several European markets.
What it means for a Tesla owner
Nothing directly, and that is worth saying plainly rather than reaching for a connection. Grid storage does not change your car, your tariff or your charging.
What it changes is the company. Tesla's energy division has been growing while its European vehicle deliveries have not, and contracts like this one are why. The cells involved are also the ones Tesla is bringing in-house — LG Energy Solution starts Lansing LFP production for Megapack in 2027 — so Megapack demand and Tesla's cell strategy are the same question. An Italian grid that can absorb more solar overnight is, eventually, a cheaper place to charge.
