Collision strengths for transitions among the energetically lowest 46 fine-structure levels belonging to the (1s2) 2s22p2,
2s2p3, 2p4, and 2s22p3
configurations of Ca XV are computed, over a wide electron energy range below 300 Ryd,
using the Dirac Atomic R-matrix Code (DARC) of Norrington & Grant ([CITE]). Resonances in the threshold region have been resolved in a fine energy mesh, and excitation rates are
determined over a wide electron temperature range below 107 K. The results are compared with those available in the literature, and the accuracy of the data is assessed.
