NCV is generally reported on an 'as received' basis. NCV determined by constant volume delivers a slightly higher result than NCV performed under constant pressure. Compared to the GCV (as received), NCV (ar) better represents the practical energy of a coal for a power station, and is a common parameter for thermal coal sale contracts.
