n this article, the preliminary routing, sizing, and cost structure of a heat network that supplies energy, in an
agrarian district, to greenhouses located around a cogeneration plant in the municipality of El Ejido (Almería)
is presented. A genetic algorithm is employed to select a set of points of consumption (plots of land)–which
indirectly determine the network routing over the road network–resulting in a project with a better net present
value. To obtain the routing, the Steiner tree problem is solved through an approximation that involves several
algorithms derived from graph theory and the use of georeferenced information. The design is constrained to
ensure technical feasibility, so that the available thermal power from the plant, averaged for hourly periods
over a year, is greater than the demand from the greenhouses. The said demand is calculated through an
empty-greenhouse climate model, considering temperature setpoints compatible with the most common crops
in the ...
