Production Cost Modeling Related to Time-Varying Rate Design

California Public Advocates Office
Project completed May 2015.

Synapse conducted PLEXOS production cost modeling and examining California investor-owned utility (CA IOU) filings pertaining to various rate design considerations in California. In particular, Synapse examined patterns of marginal costs for CA IOUs, assessing greenhouse gas emissions under different time-of-use (TOU) pricing periods, and reviewing proposed TOU periods that may reflect the changing shape of California’s “net load” curves due to the presence of increasing amounts of renewable resources, especially solar.
