12 LowVG Base case Announced transmission upgrades Includes actual wind and solar on the grid in GW of announced retirements New natural gas is built to meet future system needs 12

13 RTx10 Business as Usual Case Regional transmission upgrades Reflects currently effective State Renewable Portfolio Standards Identical thermal fleet to LowVG 13

14 RTx30 30% of all electricity demand is met by wind (20%) and solar (10%) Same transmission as the RTx10 A future where large scale transmission is difficult and solar grows significantly Identical thermal fleet to LowVG 14

15 ITx30 30% of all electricity demand is met by wind (25%) and solar (5%) Substantial inter-regional transmission expansion, including 8 HVDC lines The best wind and some solar everywhere Identical thermal fleet to LowVG 15

16 High Resolution Data Provide an accurate characterization of weather driven variability Based on meteorological conditions in 2006 Derived from historical records, satellite images, and weather models 5-minute interval 16

17 High Penetration Wind and Wind Solar Sunrise and change and Solar how sunset cause you complicate bigger, operate faster traditional operations swings power in transmission plants flow 17

18 You can have it too! NREL is releasing the data, tools, and model to the public

19 What it means to others System Operators and Engineers o Wind and solar are viable options for reducing emissions and system costs, and you can build off our work Regulators and Policy Makers o Need to ensure technical capabilities can be realized in the market place, i.e. multi-regional coordination, flexibility incentives. Academics o Large scale, applied models and tools are available to educate the next generation of power system planners and operators. Public o Wind and solar are viable sources of electricity that can dramatically reduce greenhouse gas emissions. 19

20 Recap What we did o Comprehensive model of the largest power system in the world o Analyzed whether wind and solar could technically meet 30% of the system s electricity needs What we learned o Wind and Solar change how you operate traditional power plants o Sunrise and sunset complicate operations o High Penetration Wind and Solar cause bigger, faster swings in transmission flow 20

21 What s next? Grid Modernization Laboratory Consortium o Interconnection Seams Study o North American Renewable Generation Integration Study o Markets for Reliability Services o Extreme Events Deep Decarbonization Standard Scenarios and 21
