Cogeneration efficiency

Centralized and decentralized cogeneration systems has two efficiencies as they deliver two products (heat & electricity):

$\eta_{th} = \frac{Q^-}{Q+}$

$\eta_{th}$ Thermal efficiency [%]
$Q^-$ Heat delivered by the cogeneration system [W]
$Q^+$ Heat delivered by the fuel combustion (LHV basis) [W]

$\eta_{el} = \frac{E^-}{Q+}$

$\eta_{el}$ Electrical efficiency [%]
$Q^-$ Electricity delivered by the cogeneration system [W]
$Q^+$ Heat delivered by the fuel combustion (LHV basis) [W]
