“We Only Invest in Ready-to-Build”: Why RTB Is Not a Clear-Cut Status

“We Only Invest in Ready-to-Build”: Why RTB Is Not a Clear-Cut Status

"We only invest in Ready-to-Build."

We hear this statement frequently. And the desire behind it is understandable: security, clarity, predictability.

In practice, however, it quickly becomes clear: Ready-to-Build (RTB) is not a clearly defined status. Anyone working in the market with developers, investors, and project portfolios quickly realizes that RTB is understood differently depending on investment strategy, risk profile, financing logic, and project type.

Ready-to-Build Does Not Equal Ready-to-Build

On paper, RTB sounds like a clear milestone. In reality, RTB is often a spectrum of technical, permitting, and commercial prerequisites. This is precisely where misunderstandings and valuation discrepancies arise.

The decisive questions are usually:

Grid Connection: Commitment or FCA?

  • Is a technically committed grid connection capacity sufficient
  • or is a signed FCA expected?

For many investors, the grid connection is the central gatekeeper — but the threshold for when a project is considered "secure enough" varies greatly.

Permits: Building Permit or Zoning Resolution?

  • Is a granted building permit a prerequisite
  • or is a zoning resolution sufficient?

Here too, the range is wide. Some strategies accept earlier maturity levels, others demand maximum permitting certainty.

Commercial Building Blocks: PPA and EPC Now or Later?

  • Must PPA and EPC offers already be in place
  • or are these topics for the next step?

Depending on portfolio approach, marketing strategy, and risk tolerance, whether these building blocks are part of the RTB definition or come later shifts.

Market Reality: The Entry Point Is Individual

Our experience from conversations: Every investor defines their entry point individually.

Thus RTB is less a fixed status and more an individual Ready-to-Build logic derived from internal investment criteria.

The result: Two investors can look at the same project — and come to completely different conclusions about whether it is already "RTB."

How Voltpark Approaches This: Projects by Maturity — Transparent, Structured, Comparable

This is exactly where we at Voltpark step in. We prepare projects transparently, in a structured and comparable way — along their actual maturity level.

This allows investors to make informed assessments of whether a project fits their own Ready-to-Build logic.

Conclusion: RTB Needs a Common Language and Comparability

When someone says "Ready-to-Build," they often mean "ready for our investment model." For investors and developers to connect faster, fewer buzzwords are needed — and more clear criteria, maturity logic, and comparability.

Is Now a Good Time to Buy PV Project Rights?

Two years ago, build-ready PV project rights cost north of EUR 100/kWp – today we see prices down to EUR 20/kWp. Cannibalization is pushing the solar market value to around 1.3 ct/kWh. But with a green-power storage system, the PV revenue nearly doubles. Is this the contrarian entry point?

Two Auctions Until the System Change: Ground-Mounted PV at 4.94 ct/kWh

The March 2026 ground-mounted PV auction was again clearly oversubscribed, with a bid-to-award ratio of around 2.0 – the volume-weighted award value was 4.94 ct/kWh. Despite tougher competition, prices are rising. Why, and what the last two auctions before the 2027 system change mean for build-ready projects.

Germany: 866 DSOs for 52 Million Grid Customers – What the Fragmentation Means for Developers

866 distribution system operators serve Germany's 52 million grid customers – Spain manages with 333, the Netherlands with 6. This fragmentation turns every grid connection into a standalone project, makes flexible connection agreements vary widely, and even shapes the transaction market. Why the grid area matters as early as site selection.
