Perform, Achieve and Trade (PAT)

PAT is a regulatory instrument to reduce Specific Energy Consumption (SEC) in energy intensive industries, with an associated market based mechanism to enhance the cost effectiveness through certification of excess energy saving which can be traded.
The energy intensive industries including the thermal power plants are the major players in this entire scheme of PAT. It refers to the calculation of SEC in the baseline year and projected SEC in the target year covering different forms of net energy going into the boundary of the designated consumers plant and the products leaving it over a particular cycle.
