This area is largely dominated by thermoelectric (TE) devices, though thermionic (TI) and thermophotovoltaic (TPV) systems have been developed as well.

Thus, after raising the capital to finance the new thermoelectric power station, in March 1908 construction began on the plant that would provide Lisbon and the surrounding area with electricity for more than four decades.

Utilizing funds from the Worker's Support Fund and contributions made by the Federal Treasury, the bank finances consortiums and businesses responsible for the construction of dams for the generation of hydroelectric power, power lines, thermoelectric projects and other projects with great environmental impact.

(b) Reactor NPS with electrical capacity ranging from 20 50 kW to 250 kW, in the form of NPUs based on reactors with liquid metal or gas coolants and with heat pipes based on the Brayton and Rankine cycle conversion systems and the thermoelectric conversion system.
