What it is Filled
A power plant that generates electricity and simultaneously captures the heat from generation for use in district heating, industrial processes or buildings, achieving higher overall fuel efficiency than separate generation, fuelled by natural gas in gas turbines and engines, by biomass such as wood chips, by waste or by coal, and ranging from small cogeneration units in buildings to large district heating stations; combined heat and power stations are promoted in energy and climate policy and regulated for emissions and grid connection.
Why it exists Filled
Let an agent explain combined heat and power stations and how cogeneration works, describe technologies, fuels and applications, support feasibility and policy questions at a general level, and identify notable stations with sources.
