Negratín also specialises in projects that involve cogeneration, a technology that enables us to generate electrical energy and produce usable heat from the same process. Its principal application is in those industries that use steam and/or hot water and, in general, in any facility that consumes heat or refrigeration, as well as in facilities that produce a surplus of heat that can be used to generate electrical energy. In Spain cogeneration is included alongside renewable energies in the Special Electrical Energy Generation Scheme, the objective of which is the promotion of renewable and efficient electricity generation.
