Agenda Overview DAY ONE Calculator Overview Resource Costs and Potential LUNCH (12-1) Resource Costs and Potential (cont’d) BREAK (3:15) Resource Valuation DAY TWO Resource Valuation (cont’d) Energy-Only Procurement and Transmission Planning BREAK (10:45) CAISO Energy-Only Planning LUNCH (12-1) Process Alignment BREAK (3:15) Role of RPS Calculator in Statewide 33% RPS Transmission Planning

11. RPS Calculator Past and Present 2009: RPS Calculator created by CPUC RPS staff – Informed 33% RPS Implementation Assessment 2010: RPS Calculator integrated into LTPP proceeding – Output used to inform LTPP system and CAISO transmission planning efforts 2014 (Jan): RPS Calculator added to RPS Proceeding – Calculator design & administration is now part of RPS proceeding. RPS now supports LTPP’s planning efforts. 2014 (Oct): RPS Calculator v6.0 staff proposal issued 2015 (Feb): RPS Calculator v6.0 Workshop

12. How RPS Portfolios are Used in Long- Term Planning Studies RPS Vets and adopts RPS Calculator methodologies, inputs and assumptions annually and develops RPS portfolios RPS submits portfolios to LTPP for generation planning LTPP Vets and adopts combinations of assumptions (including RPS portfolios) to construct multiple scenarios for use in long term planning analysis Output LTPP scenario analysis informs CPUC procurement authorizations LTPP scenarios (with associated RPS portfolios) are provided to CAISO for use in TPP. TPP may approve new transmission infrastructure if needed to serve scenario/case.

13. RPS Calculator Next Steps 2015 Q3: Issue draft v6.1 with draft portfolios for comment 2015 Q4: Finalize and adopt v6.1 and associated portfolios via ruling (tentative, pending workshop comments) Additional rulings will be issued later this year seeking comments on outstanding Calculator-related issues (e.g., environmental scoring) and scheduling additional workshops as needed.
