Review of SCEs LCR RFO March 28, 2016 1 Southern California Edison - PowerPoint PPT Presentation

IDER Workshop – Competitive Solicitations Review of SCE’s LCR RFO March 28, 2016 1 Southern California Edison

LCR Objectives & Procurement Authorization • Primary Objective of LCR RFO • Seek new resources in both West LA Basin and Moorpark • LA Basin has CPUC ‐ defined targets for technology “buckets” • There are no CPUC ‐ defined technology “buckets” for Moorpark • Secondary Objective • Seek to procure MW to support Preferred Resources Pilot (PRP)  Johanna and Santiago sub ‐ areas • Improve reliability of Goleta sub ‐ area Target Description LA Basin MW** Moorpark MW Preferred and energy storage range 550 - 1,450 - Energy storage minimum 50 (Separate Requirement) - Gas-fired generation range 1,000 - 1,500 - All ‐ source * range 300 ‐ 500 215 ‐ 290 Total range 1,900 ‐ 2,500 215 ‐ 290 * All ‐ source means all technologies compete against each other with selection awarded consistent with the Loading Order and need assessments ** Procurement authority for both LTPP Track I and Track IV 2 Southern California Edison

RFO Process • 2 step solicitation leveraged • Issued RFO documents to market • SCE hosted bidders conference • Indicative offers submitted to SCE • Shortlisting process completed and notifications made to counterparties • Negotiations completed • Final offers submitted to SCE • Agreements signed by all parties 3 Southern California Edison

LA Basin Final Selection • SCE procured approximately 170 MW less than the Track IV minimum authorization and is working with the CAISO to determine whether additional resources are needed RESOURCE COUNTERPARTY LCR DETAILS TOTAL BUCKET MW LCR MW 640 Combined Cycle, GE 7FA 2X1, ~ 6.8 HR @ Alamitos AES 640 Gas ‐ fired Generation AES 644 Combined Cycle, GE 7FA 2X1, ~ 6.8 HR @ Huntington Beach 644 (GFG) Wellhead (DBE) 98 2LM 6000 Peakers @ Barre (RA ‐ only Contract) 98 TOTAL GFG 1,382 Sun Power 10.32 Behind the Meter (BTM) Solar in J/S* Renewables (RPS) 38 27.6 BTM* Solar in LA Basin Sun Power Ice Bear 28.64 ES BTM Permanent Load Shift Thermal ES in J/S AES 100 Front of Meter (IFOM) 4hr @ Alamitos Energy Storage (ES) 264 Stem 85 BTM 4 hour like DR Hybrid Electric 50 BTM 4 hour like DR 23.36 EE offers in J/S Energy Efficiency Onsite Energy, Sterling Analytics, 124 (EE) & NRG 100.68 EE offers in LA Basin Destributed 70 Distributed BTM generation that functions like DR NRG 70 Generation (DG) Demand Response 5 Traditional DR in LA Basin, at least 4 hour dispatch NRG 5 (DR) TOTAL PREFERRED RESOURCES & ENERGY STORAGE 431 TOTAL 1,813 * Behind the meter energy storage Final list of contracts subject to change 4 Southern California Edison

Moorpark Final Selection • Contract with the GFG resource is in the form of a fixed price RA ‐ only contract to avoid capital lease treatment *This ES offer includes 54 MW of Ellwood GFG enhancement. The 54 MW does not count towards the LCR MW target Final list of contracts subject to change 5 Southern California Edison

LCR RFO Process – What Worked Well • Successfully executed a first ‐ of ‐ its ‐ kind, head ‐ to ‐ head competition of all resource types • Market proposed wide range of innovative products • “Open for business” approach allowed for customized contracts for new products • Developed methodology to determine savings through M&V protocols • Methodologies distinct from DSM program EM&V approaches • Relationship management with bidders • Valuation approach that allowed SCE to compare costs and benefits across resources 6 Southern California Edison

LCR RFO Process – Challenges • Difficult task of creating pro forma contracts for new products like energy storage and aggregated energy efficiency • RFO schedule – there was too little time between RFO launch and indicative offer and the negotiations ultimately drug on too long • Requirements changed– LEFs, updated codes and standards, 20 minute response time, 2 hour vs 4 hour • Accounting concerns caused delays and contracting complexity • Many cross ‐ cutting issues to address, particularly with energy storage but also with PLS and renewable DG • Incrementality – how to prove a resource is incremental to something that has not yet happened; how to ensure incrementality as legislation (e.g. AB 802), proceedings (EE OIR), and building code evolves over time (e.g. Title 24) • Valuation challenges ensuring all products were valued fairly, particularly as it relates to energy storage • Implementation concern about overlapping preferred resource offerings especially in focused local areas resulting in customer offer fatigue and competing objectives (i.e. CPUC EE goal and LCR goal) 7 Southern California Edison
