Solar PV Growth At SCE

Solar PV is the fastest growing resource in our renewable portfolio.

As the cost of solar PV declines, the more of it we can purchase cost-effectively.

SCE’s Comprehensive Approach to Solar

While many options exist for renewables developers, the magnitude of RPS
goals drives SCE to procure large volumes through its competitive solicitations.

SCE has also found value in utility scale distributed solar as a means to achieve
RPS compliance and provide greater flexibility in our procurement portfolio.

Utility Implications of larger volumes of Solar

Solar PV is one of our fastest growing renewable resources, but also one of
the most difficult to forecast

Intermittency Challenges
•
Lower Cost  Larger Supply  Greater Output Variability of Portfolio
•
Energy storage has potential to mitigate need for back-up generation
and could resolve intermittency issues, but not yet technically or
economically feasible for utilities
