Galio Técnicas Energéticas (GTE) used different business models depending on the country where the project is implemented. Thus, in countries like Japan, our company acts as a SUPPLIER of solar PV trackers , sending them from their factories in Jerez de la Frontera (Spain), to the port of destination

In several markets ,Galio Técnicas Energéticas works as INSTALLER or EPC (Engineering, procurement and construction). Under this scheme, GTE takes the whole instalation of the PV plant, with the advantage of being manufacturer of his own revolutionary trackers whih gives our company a technical and economic advantage over all competitors.

GTE performs some actions as PROMOTER or PPA (Power purchase agreement). In this case, with the financial assistance of Fondos JESSICA ( BEI- IDEA - BBVA) and EEA- Grants- CDTI and technical collaboration of CENER and the Norwegian industry Eltek, Galio Técnicas Energéticas will promote an isolated from net PV system with energy storage system in its Galio 1 plant of Jerez de la Frontera.

This instalation will allow the manufacturing plant to become the first factory in the world, renewable electric island exploited in high performance mode. This means that the plant is disconnected from the public electric net, moving to maintain continuous production, 24 (hr/day), 360 (days/year) through the only supply a solar PV electricity cost at 2 (c€/kWh), and remaining fixed during the expected life of the PV system, which is 40 years. Note that, this plant currently pays the electricity supplier 23 (c€/kWh) , and they will increase markedly over the next 40 years.

This business model, either as supplier, EPC or PPA, adapts to the different natures and ways of operating a PV system.

There are four main ways of operating a PV system.

The first, and most famous, is the PV grid connected. These facilities are designed to generate electricity for full injection into the network using a pool or subsidized sale, depending on market. GTE only performs these facilities in Japan, where the suspension of its nuclear fleet has led his administration to introduce a bonus tariff FIT (Feed In Tariff), in order to induce the promotion of renewable electricity generation facilities.

The second way is a self-consumption PV system connected to the network via a bidirectional meter that allows the in situ generated energy consumption and pour the leftover to network. GTE does not perform this type of installation.

Thirdly, FV isolated from network. It is a generation that does not connect under any circumstances, to the public network. The promoter (PPA ),which is, in this case, the owner of the PV system and the factory that supplies power to the PV generates electricity for its own exclusive use. The possible excess of electricity is stored in the form of hydrogen gas or accumulates in battery systems, this kind generation installation can not pour electricity to the grid. GTE is a pioneer and leader in isolated PV installations of high profitability; executing ready to use instalations as EPC, at 1.5 (€/Wp), using one axis solar trackerss and top quality PV panel. The result is a electricity for the PPA, at a final price from 2 (c€/kWh) to 3 (c€/kWh). These PV systems are isolated from network through three barriers, physical, electrical and other electronics. There is another reason not to connect to the power grid ,the common sense. The electricity produced at the facility is a precious product that supplies the energy needed for the manufacturing process of the PPA. Valuable surplus electricity is accumulated in the form of hydrogen for later use. In this kind of exploitation of the PV, the solar system is isolated from the network , while the manufacturing plant that supplies power is not disconnected from the network, since it has public network connection for emergencies.

The fourth is the rural electrification through PV. It is a variety of FV isolated from network. The only difference is that the installation is in a location where there is no provision of the public electric grid. They are of great social interest because they provide access to electricity to areas without such service. They have huge environmental interest when used to replace generators in areas not electrified but who can afford the investment and the high cost of this method of power generation. GTE offer the most profitable generation PV plants and energy storage in the form of hydrogen facilities in the market. The promoter (PPA), which is, in this case, the owner of the PV system and the factory that consumes the power, generates electricity for its own exclusive use.

Third and fourth way are both isolated from network. The difference between them is that in the third, the PPA has switched public network connection, although the PV system can never sell eletricity to the network. In the fourth way, the PPA does not have access to public network that it is not implemented in the location of industrial activity in the PPA.

The last two models, Isolated PV and Not electrified zone PV, which the only difference is whether the PV system competes againnst the public network or not, are the energy models of the future. They are based on a fundamental criterion , and that has not been accessible until now, is in-situ the power generation, producing electricity in the points with high electrical demand. Thus the cost of electric transmission through the power distribution network and electricity losses during transmission over the network are saved.

Isolated PV and Not electrified zone PV represent a saving for the PPA by generating a much cheaper electricity than the offered by the electric companies.

Galio Técnicas Energéticas integrates optionally hydrogen and oxygen generators, so as to achieve savings in electricity bills of manufacturing plants over 90 %.
