auma prepared the basic design of a photovoltaic plant for a public hospital in Vallès and, with it, the technical and administrative documents to tender the works: what turns a sound energy idea into an awardable contract.

The challenge
A hospital is one of the most demanding buildings for on-site generation, and a public body cannot buy it the way a private company would:
- Critical 24/7 service: the works cannot compromise supply or clinical activity at any point.
- Very specific demand: the hospital load profile governs how the installation is sized.
- Public procurement: the specification had to define scope precisely and allow objective comparison of bids.
The auma solution
The assignment covers both halves of the problem: the technical and the contractual.
- Basic design sized to the centre's real consumption profile and the roof's conditions.
- Technical specification with requirements, materials and quality criteria defined without ambiguity.
- Administrative specification with award criteria that allow bids to be assessed objectively and comparably.
The result
- The consortium holds the design and tender documents needed to put the installation out to bid.
- Award criteria that reward technical quality, not price alone.
- An essential public facility prepared to generate part of its own energy.
In the public sector, a good energy design without a good specification never gets built: it stays a well-written report.
Frequently asked questions
Why does solar self-consumption make sense for a hospital?
Because it has high, continuous, daytime consumption that closely matches the solar generation curve. That means a large share of the energy generated is consumed on site, which is where the real saving lies.
What should a solar tender specification contain?
The scope, equipment and material requirements, execution and commissioning conditions, warranties, maintenance, and the acceptance and performance measurement criteria.
Who defines the award criteria?
The contracting body, usually with technical assistance. Thisowner's engineer role makes sure what is contracted and what is finally built are the same thing.
Want your public facility to generate its own energy?
We prepare the design and the tender documents so the procurement actually reaches completion.
