1. California Energy Commission California Energy Demand 2016-2026 Revised Electricity Forecast: Southern California Edison Planning Area December 17, 2015 Cary Garcia Demand Analysis Office Cary.Garcia@energy.ca.gov 1

2. California Energy Commission Forecast Summary Planning area is now the SCE TAC area –Five climate zones Electricity consumption growth in the new mid case is lower than in CEDU 2014 because of new standards; offset somewhat by higher growth in number of households Sales and peak forecasts down more significantly because of higher PV adoption More growth in inland climate zones 2

3. California Energy Commission SCE Baseline Electricity Consumption New mid case grows by 0.95% per year 2014-2025, compared to 1.16% in CEDU 2014 mid case for planning area under old definition 3

4. California Energy Commission SCE Baseline Electricity Sales New mid case grows at 0.45% per year (2014-2025) compared to 1.03% for CEDU 2014 mid case 4

5. California Energy Commission SCE Baseline Peak Demand New mid case more than 3,000 MW below CEDU 2014 mid case by 2025 5

6. California Energy Commission SCE PV Energy Around 4,000 GWh difference between new mid case and CEDU 2014 mid case with old planning area definition 6

7. California Energy Commission SCE PV Peak Impacts CED 2015 Revised mid case corresponds to around 4,500 MW capacity in 2026 7

8. California Energy Commission SCE Light-Duty EV Energy Corresponds to around 800,000 EVs in 2026 in the mid case 8

9. California Energy Commission SCE Committed Efficiency Around 17,000 GWh savings from codes and standards in 2014 9

10. California Energy Commission Committed Efficiency Programs: EM&V Adjustment Net effect: +18 GWh in 2015, -35 GWh in 2026 10

11. California Energy Commission Additional Impacts Climate change –200 GWh in 2026 in mid case, 250 GWh in high case –175 MW in 2026 in mid case, 280 MW in high case Electrification: 400 GWh in 2026 in mid case, 650 GWh in high case 75 MW of demand-side DR in 2026 11
