PPAs, Grid Connections, Flexibility: How a Datacenter Secures Its Power (and Its Valuation)

A datacenter without secured power is not an asset; it is an empty shell. Yet many transactions still focus on walls, fiber and PUE. The question that should open any due diligence is simpler: where does the power come from, for how long, and at what price?

Three documents now determine a site's value: the grid connection agreement with the transmission operator, the supply contract, and the operating permit. If any of the three is missing or expiring, the site's theoretical valuation collapses.

The first document is the rarest. In France, a connection of several tens of megawatts is negotiated over five to seven years with RTE. Operators holding a firm agreement, with a guaranteed date and capacity, effectively hold an option on the market.

The PPA Has Become the Standard

Hyperscalers and AI factories now sign long-term power purchase agreements, ten to twenty years, directly with producers. These PPAs lock in price, guarantee the decarbonized origin of the energy, and reassure the banks financing the projects. In Romania as in Spain, developers no longer announce a site without an associated PPA.

For an investor, a datacenter backed by a long PPA reads like a property backed by a solid lease: predictable income, controlled energy costs, limited residual risk. Conversely, a site exposed to market prices can see its margin halved within a few months of power tension.

The Energy Due Diligence Checklist

Before acquiring, four checks are essential. Contracted capacity and its delivery date. The ability to scale up without going back into the queue. The indexation clauses of the purchase contract. And the robustness of the substation the site is attached to.

Two more recent questions join the list. Can the site participate in flexibility and demand-response schemes, which pay large consumers able to shed load at peak times? And can it host storage or backup generation? Those options are worth more every year.

How We Apply This at FINXIA

In the TITAN DC AI strategy, no file reaches the investment committee without a full energy review conducted before any offer. This is often where projects die: uncertain connection, no PPA at an acceptable price, or capacity insufficient for the densities of the next GPU generations.

This discipline explains our preference for brown assets. An industrial site with a historic 20 MW agreement and a valid operating permit offers a foundation no greenfield can match for years. Transformation costs money, but time saved is priceless in this market.

Key Takeaways

A datacenter's value now sits in its energy contracts as much as in its walls. Long PPA, firm connection, flexibility options: these are the three pillars of a defensible valuation.

Worth watching: the evolution of capacity and demand-response mechanisms in France and Spain. They could add a significant revenue line to well-equipped assets by 2028.
