NatPower SA and Tesla Inc. signed a multi-year supply and execution agreement on June 23, 2026, to deploy more than 25 gigawatt hours of battery energy storage systems across Italy and the United Kingdom—one of the largest cross-border storage commitments announced in Europe to date.
The Luxembourg-registered energy infrastructure company will own and operate the facilities, with Tesla supplying the hardware, construction services, and trading technology.
Agreement details and initial scope
The deal centers on five projects across Italy and the United Kingdom, totaling more than 25 GWh of battery energy storage capacity — a significant commitment for a single cross-border framework.
Tesla will supply its Megapack units, the company’s large-scale battery storage product, and will handle engineering, procurement, and construction. That EPC role means Tesla is not simply a hardware vendor. It is embedded in the delivery process from design through commissioning, a distinction that shapes how the entire partnership functions.
Revenue management is also part of Tesla’s scope. The Autobidder platform will handle trading optimization for the deployed assets, and Tesla will provide long-term revenue warranties alongside those services. Hardware, construction, and trading under one agreement — that combination is central to how the partnership is structured.
Why the deal is structured as a single integrated framework
NatPower describes the arrangement as the first time, at this scale, that BESS procurement, financing, and execution have been coordinated across multiple jurisdictions under a single integrated framework. The key mechanism is a direct link between manufacturing allocation and project delivery—battery supply is tied explicitly to construction schedules rather than managed as a separate workstream.
That linkage is designed to reduce the execution bottlenecks that have historically slowed large storage rollouts. NatPower CEO Fabrizio Zago identified consistent delivery as the sector’s core problem. “The sector has access to technology and capital but still struggles to deliver infrastructure consistently and within the required timelines,” he said in the company’s statement. The solution, as Zago described it, is an ecosystem that aligns capital with execution—one replicable across additional markets.
Tesla VP Mike Snyder pointed to vertical integration as the reason the framework is achievable. “Our team of experts are helping accelerate these deployments through our vertically integrated offering, providing hardware, software, construction, trading optimization, and service to bring projects online faster,” Snyder said. That end-to-end capability — spanning physical infrastructure and software — is what makes coordinated execution across two countries operationally viable.
Projected financial scale and intended uses of the storage assets
The financial figures here are substantial. NatPower estimates aggregate construction value across the full scope at $4 billion to $5 billion, with expected project revenues over a 20-year horizon exceeding $15 billion.
Those projections reflect both the capital intensity of utility-scale battery storage and the long operational lifespans these assets are designed for. Storage infrastructure of this type does not generate revenue in a single transaction — it earns over decades through grid services, energy arbitrage, and capacity contracts.
The deployed assets are intended to serve multiple functions. NatPower says the facilities will provide grid stabilization and renewable generation optimization and will supply dispatchable capacity to high-demand end users. Target customers named in the company’s statement are data centers and energy-intensive industrial operations — two categories driving significant new energy infrastructure investment across Europe.
Context: European power system pressures driving storage demand
The timing of this agreement reflects real and growing pressure on European power systems. NatPower’s statement links the deal directly to converging forces: electrification of transport and heating, the intermittency of wind and solar generation, and rising energy consumption tied to artificial intelligence infrastructure.
Each trend independently increases demand for flexible, dispatchable energy resources. Together, they create a structural need for large-scale storage that can absorb excess generation and release it when and where the grid requires it. The partnership is explicitly designed with that broader context in mind.
Phase 1 covers Italy and the UK, but the framework NatPower and Tesla have built is intended to extend to additional European markets. The companies have stated plans to grow total partnership capacity to more than 100 GWh in future phases — quadrupling the initial commitment. NatPower, registered in Luxembourg, owns and operates the facilities, positioning it as a long-term infrastructure holder rather than a developer that exits after construction, which aligns with the 20-year revenue projections the company has cited.
Power for data centers
The NatPower-Tesla agreement represents a multi-year commitment to deploy more than 25 GWh of battery storage across five projects in Italy and the UK, with a stated ambition to scale beyond 100 GWh. Tesla’s role covers Megapack supply, EPC services, and trading optimization through its Autobidder platform, with long-term revenue warranties included.
The deal’s structure — linking manufacturing, financing, and construction under one cross-border framework — is presented as a first at this scale. Estimated construction value ranges from $4 billion to $5 billion, with projected revenues exceeding $15 billion over 20 years. The assets are intended to serve grid stabilization needs and supply power to data centers and industrial users as European energy demand continues to grow.
