The increased brilliance and coherence of X-ray beams as a result of low-emittance light source upgrades present new opportunities and challenges for X-ray emission spectroscopy. Increased brilliance provides new capabilities, but only so long as photon detection can keep up and sample radiolysis can be kept under control.  A possible alternative to energy scanning emission spectrometers  are a new generation of energy dispersive superconducting-transition-edge spectrometers (TES). Results from a recently commissioned TES at Stanford Synchrotron Radiation Laboratory will be presented.
