El proyecto, que incluye el desarrollo de una comunidad energética, cuenta con un presupuesto de 1,30 millones de euros.
Why it matters: Public tenders for energy communities are the new high-margin frontier in Spain, but the structural and administrative overhead will bankrupt installers who bid with rooftop-only mindsets.
At first glance, a 358 kWp project with a €1.3 million price tag looks like a typo or a massive windfall. That’s roughly €3,631 per kWp—nearly triple the cost of a standard C&I rooftop installation. But if you’re an installer looking at this tender in Vilanova i la Geltrú, put your calculator down and look at the structural reality first. This isn't just about bolting modules to a roof; it’s a high-stakes engineering play in a corrosive coastal environment.
The Structural Margin-Killer
Building a marquesina (canopy) over active sports tracks like the Carme Sugranyes Blay requires more than just standard rails. You’re dealing with significant wind loads and, crucially, the C4/C5 corrosion categories typical of the Mediterranean coast. If you don't spec high-grade galvanized steel or specialized aluminum alloys, you’ll be back there in five years replacing rusted struts on your own dime. For those bidding, ensure your quote accounts for UNE-EN 1090 execution classes; otherwise, the municipal inspectors will shut you down before the first inverter is mounted.
The CEL Administrative Trap
The real 'hidden' cost here isn't the steel—it's the Comunidad Energética Local (CEL) component. In Spain, setting up a shared self-consumption scheme under RD 244/2019 and the expanded 2km radius rule is an administrative nightmare. You aren't just an EPC; you’re becoming a de facto utility consultant. You’ll need to manage the coefficient distribution (fixed or dynamic) for dozens of local neighbors and public buildings.
If you treat this like a simple PPA or a CAPEX sale, the bureaucracy will eat your 20% margin for breakfast. This is a project for developers who have a dedicated legal desk and a structural engineer who doesn't mind getting their boots dirty.
