Plenty of sites buy electricity off the grid and burn separate fuel for heat. Cogeneration does both jobs at once, from a single fuel source.
That's the whole idea behind combined heat and power. One engine generates electricity on site, and the heat that would otherwise be lost gets captured and used for hot water, process heat or steam. Two outputs, one fuel, far less waste.
It's why the technology keeps turning up at wastewater plants, abattoirs and food factories, anywhere with steady heat and power demand under one roof.
World Cogeneration Day (4 September) is a good prompt to ask whether your site is doing it the hard way.
