RTB vs Shovel-Ready Solar Projects: A Cross-Border Comparison
Ready-To-Build (RTB) and shovel-ready describe substantially the same solar project maturity stage, expressed in different regulatory traditions. Understanding the equivalence — and the small but practical differences — matters for international investors moving between markets.
RTB: the Italian and European convention
In Italy and most of continental Europe, “Ready-To-Build” refers to a project that has completed its authorisation pathway and is positioned for construction. The Italian definition rests on documented milestones:
- AU (Autorizzazione Unica) or PAS issued
- VIA / Screening / VIncA closed where applicable
- TICA accepted, STMG defined with the DSO/TSO
- Land control secured under registered surface rights or lease
The detailed framework is covered in our page on ready-to-build solar projects.
Shovel-ready: the Anglo-Saxon convention
“Shovel-ready” originates in US infrastructure policy and is widely used in the UK and Australia. It describes a project ready to begin physical groundworks — practically, this means:
- Building permits issued
- Environmental clearances (NEPA in the US, EIA in the UK) completed
- Interconnection Agreement signed with the utility / ISO
- Site control (purchase, lease, easement) registered
- EPC tender package ready or EPC contract signed
The functional equivalence with Italian RTB is strong. A US investor evaluating an Italian RTB project will find each of these elements has an Italian counterpart — see our dedicated page on shovel-ready solar projects for the translation.
Practical differences that matter
While the stages are equivalent, three areas often require attention:
- Document equivalence: AU decree ≠ Building Permit one-to-one. AU is a comprehensive single-authorisation that bundles building, environmental and grid permissions. A US investor expecting separate documents needs to understand this consolidation.
- Grid connection: TICA + STMG in Italy serves the same function as an Interconnection Agreement in the US, but with different milestone definitions and acceptance procedures.
- Land control: Italian surface rights (diritto di superficie) under Civil Code Art. 952 are conceptually similar to a long-term lease with optional renewal, but with specific registration and tax implications.
How we operate: scouting, not brokerage
READYTOBUILD.SOLAR operates as an independent scouting and advisory platform. We identify, qualify and present Italian solar projects to international investors. We are not a broker, dealer, financial advisor or regulated intermediary, and we do not provide investment advice, securities placement or capital markets services.
Our role is to bridge the information gap between Italian developers and international capital. Investors and developers engage their own legal, technical and financial counsel for transaction execution.
Which projects fit each terminology
- RTB / shovel-ready: ready for construction now
- Late-stage: nearing RTB but with residual milestones
- Investment-ready (IC-ready): dossier complete for committee review, but construction permits may still be pending
For country-level context on the Italian market, see solar projects in Italy.
READYTOBUILD.SOLAR is part of a wider Italian solar platform ecosystem: rtb.solar for Italian-language marketplace access, sviluppo.solar for co-development opportunities, and terreni.solar for land sourcing and site control.

Frequently Asked Questions
- Are RTB and shovel-ready the same thing?
- Substantially yes. Both terms describe a solar project that has cleared its permitting hurdles and is ready to enter construction. RTB is the standard term in Italy and continental Europe; shovel-ready is the common US, UK and Australian equivalent.
- Why use two different terms?
- The terms reflect different regulatory traditions. RTB emphasises completion of authorisation (AU/PAS in Italy), while shovel-ready emphasises readiness for physical groundworks. The underlying maturity is comparable.
- Does an Italian RTB project meet US shovel-ready criteria?
- Generally yes, but documentation may need to be translated and contextualised. US investors should expect different document categories (AU decree vs Building Permit, STMG vs Interconnection Agreement) covering equivalent functions.
- Which term should an international investor use?
- Use the term of the target market. When sourcing in Italy, refer to RTB; when reporting to a US investment committee, translate as shovel-ready. The asset is the same.
- Is there a stage between RTB and shovel-ready?
- Not really. The difference is terminological rather than substantive. Genuine intermediate stages have their own names: late-stage, investment-ready, NTP-ready, construction-ready.
