Electricity
In 1904 Prince Ginori-Conti harnessed steam power to create electricity and lit the first 5 light, bulbs. In 1905
the factory and town of Larderello. were illuminated by electric power.
The power plant N.1 at Larderello went into
operation in 1915 with two 2570 KW generators; the cooling towers were made of wood, as in the scale models.
If the damp steam was transferred directly to the
turbine it caused corrosion and incrustations. Therefore, the natural steam transferred heat to a secondary fluid,
pure water, which in a heat exchanger was transformed into steam which was then fed into a turbine.
The turbo alternator on display dates from 1923: it was an experimental machine that Produced 23 KW of energy.
It was salvaged during the war and connected to a fumarole and was put back into operation. It supplied electric
energy for the welding to repair the damaged turbo alternators of power station N.2. Just one month after the fighting
troops withdrew from the area, the units were again supplying electric energy to the national network.
After the Soffionissimo was tapped in 1931, electric energy production developed rapidly thanks to the enormous
power of the new fumaroles. By 1939 the original installed 14MW of 1933 had risen to 66 mw.
The first reinforced concrete cooling towers to replace the original wood structures were built in 1937.
The showcases in the internal ring of the dome contain various electric measuring instruments.
The electric power stations were rebuilt after World War II. Since the steam was superheated by
About 30 degrees C with respect to the vaporization curve, and did not create deposits or incrustations, the turbines
in the new station were fed directly by steam coming from the ground, so the secondary steam was no longer needed.
