Isolated industrial installation with renewables and generator set
Pallars (Lleida)
July 2024
With isolated electrification systems, for years we have been able to propose installations, even industrial ones, without limitations on location, power and use, since these can be implemented anywhere. Today what is most important is to have a secure water supply, everything else is perfectly feasible.
Industrial isolated electrification systems came after those for residential use, since in these latter cases less power and complexity of the systems were required. This facility, which we now present to you, is located in LLeida, specifically in the Pallars region, and is intended to supply some wineries along with a house for residential use owned by the owners of the winery. Isolated industrial or residential electrification combines a multitude of equipment, which is intended to offer the necessary power, the expected reliability and the comfort of having an energy system that is as reliable or more reliable than those connected to the grid.
In Lleida, the interior area of Tarragona, Huesca and Teruel, there are many of these facilities, since they have large rural areas where the power lines do not pass, so it is essential to implement isolated electrification systems, equipped with the most modern and sophisticated systems. production, storage, control and distribution of energy.
Isolated electrification installations began with electrical generation equipment based on generator sets. No solar panels, batteries or inverters. The first task of our company, back in the 60’s, was to provide electricity based on generator sets, the areas isolated from the electrical grid. It didn’t take us long to install dynamos and batteries, but we still did not have the necessary technology like today’s inverters, so the electrification was either direct from the group, alternating at 230V or 400V or accumulated at 12 or 24V from batteries, to power the lighting and some small consumers that could operate with direct current.
In Lleida and Huesca, a number of these installations were made isolated from the electrical grid, some of them continue to operate today; But to tell the truth, the arrival of inverters revolutionized the market and electrical installations isolated from the grid, being able to offer a standardized alternating current supply, which definitively promoted the implementation of this type of isolated electrification installations. But… at the beginning of their journey, inverters were not like those of today, that is: pure sine wave, 50Hz, etc., they caused quite a few problems; but like everything, over time they evolved to the sophisticated and reliable systems of today, which continue to combine: the generating set with photovoltaic systems, lithium batteries and incredible control and monitoring systems of all the equipment that make it Everything is combined and harmonized to provide the best performance and energy savings.
I can firmly state that today’s isolated electrification system is as reliable, safe, and just as profitable (and in some cases, more so) than the grid connection.
