Abstract: In non-limiting examples of the present disclosure, IP-CEMS-compliant systems and methods for in situ monitoring, measuring, analyzing, and predicting emissions output from emission sources are presented. In preferred implementations, UV-DOAS and TDLAS systems generally comprise a light source, one or more optical elements, two optical transmission windows on opposite sides of a flue stack, a folded-path multi-pass calibration gas cell containing a calibration gas through which a light beam from the light source propagates within the cell via multiple reflections from internal mirrors, a detector for receiving a transmitted optical signal from the emissions stack or calibration gas cell, an analyzer and/or spectrometer for measuring one or more properties of a target gas from the flue stack, wherein the effective pathlength of the calibration gas cell is substantially equal to the stack pathlength.

Abstract: A system for generating electricity includes a generator and an interface. The generator is coupled to the interface and provides data to the interface regarding electricity generation. The interface is coupled to a control node for monitoring and controlling the generator. The control node may be coupled to the generator through a medium such as the internet. In some aspects of the invention, a continuous emissions monitoring system is provided for fossil-fuel based generators to enhance operation and reduce emissions of such generators.
