Brownfield solar projects in Italy, ready for grid connection

What brownfield solar projects are on this site

The word brownfield is used in different ways in the energy sector. Here it has a precise meaning: a pre-COD solar plant that is mechanically complete or close to it, with modules, inverters and the internal electrical system installed, and that is waiting for the grid operator to complete its part and activate the connection.

It sits between two other stages. Before it there are ready-to-build projects and turnkey plants still under construction; after it there are operating solar plants with a production history. A brownfield plant has no revenue track record yet, but most of the capex has been spent and the physical asset can be inspected.

Why investors look for solar plants ready for grid connection

• Lower construction risk: the plant exists and its quality can be checked on site.
• Visible capex: costs are largely incurred and documented, so the remaining items are easier to identify.
• Shorter path to revenues compared with RTB, because the open items concern mainly connection and commissioning.
• Different seller motivations: developers or EPC contractors may want to recycle capital before COD, which can make a transaction possible at this stage.

The trade-off is that the remaining risk is concentrated in the grid connection, which is outside the control of both buyer and seller.

What to check in a mechanically complete solar plant for sale

Your technical and legal advisors will define the scope of the due diligence. The points that usually matter most at this stage are:

1. Status of grid works: whether the network works required by the STMG are completed, in progress or still to be authorised, and who is responsible for them.
2. User installation and network installation: the distinction between the works built by the producer and those that pass to the grid operator, and the status of their handover.
3. Tests and inspections: mechanical completion, cold and hot commissioning tests, and the as-built documentation.
4. Operating regulation: the agreement with the grid operator that governs how the plant operates once connected.
5. Permits and compliance: the PAS or AU, any variations during construction, and compliance with the permitted layout.
6. EPC contract: warranties, retentions, defect liability and open claims.

A broader list is available in our guide to solar due diligence.

Activation timing: the factors, not a promise

How long a brownfield plant waits for energisation depends on factors that vary from case to case: the extent of the network works, the voltage level and whether Terna or a distributor is involved, the need for authorisations for the grid works, the grid operator schedule and the completion of documentation on the producer side. The teaser reports the estimated days to connection declared for each project, so you can compare opportunities. Read more in grid connection timeline.

Structures and contracts

Brownfield plants are normally sold through an SPV share deal, which keeps permits, the STMG and contracts in the same company, or through an asset deal where those elements are transferred to the buyer. See solar SPV share deal for the main differences. Contracts to evaluate include the EPC contract, any O&M agreement already signed and, where applicable, the route to market chosen for the energy, such as a PPA or access to FER X.

How to receive brownfield opportunities
