Thank you to WAUZIH for sending me photos of the construction area on Paul da Serra.

The Calheta Hydroelectric Utilisation Expansion Project (Calheta III) aims, in addition to increasing hydroelectric production, to store energy in the form of water. Thus, when there is an excess of renewable production, instead of rejecting energy, it is used to pump water to a reservoir, at high altitude, and then, at rush hour, that water used in the hydroelectric power station to produce energy. In this sense, the project is a structuring component of the island’s electrical system, which is essential for increasing renewable energies and avoiding the rejection of energy from existing and other facilities that may be built. The protection also makes an important contribution to reducing dependence on the outside.
