Transmission Inputs
IOUs may include
preferences for
projects in areas
with approved
transmission lines
(e.g. TRTP)
Bidders incorporate
transmission costs
into bids – based
on TRCRs,
transmission
studies, or LGIAs
IOUs consider
transmission costs based
on TRCRs, transmission
studies or LGIAs
Transmission
costs and/or
limits on costs
incorporated
into PPA terms

• Purpose of TRCR is to provide cost
information to be used for evaluating
renewable resource bids so that the
least-cost, best-fit bids are selected.

• TRCRs update is initiated by CPUC at the same time annual RPS Procurement Plans are initiated.
• IOUs issue requests for information regarding projects to interconnect to its transmission system. – Location, size, interconnection point, online
date, etc.
• IOU issues report based on information received, transmission study results, and other available studies.
