Slide1:  Eastern Wind Integration and Transmission Study Overview January 28th Webinar Dave Corbus National Wind Technology Center National Renewable Energy Lab Eastern Wind Integration& Transmission Study :  Eastern Wind Integration& Transmission Study Objectives Evaluate the power system impacts and transmission associated with increasing wind capacity to 20% and 30% of retail electric energy sales in the study area by 2024 ; Impacts include operating due to variability and uncertainty of wind; reliability Produce meaningful, broadly supported results through a technically rigorous, inclusive study process. Key Issues & Questions include:  Key Issues & Questions include What system operational impacts and costs are imposed by wind generation variability and uncertainty? What are the benefits from long distance transmission that accesses multiple wind resources that are geographically diverse? How do remote wind resources compare to local wind resources? How much does geographical diversity help reduce system variability and uncertainty?

Regional Wind Requirements:  Regional Wind Requirements Four EWITS Scenarios:  Four EWITS Scenarios Scenario 1, 20% wind penetration – “Lowest Cost Wind”: Utilizes high quality wind resources in the Great Plans, and in the best Eastern locations. Total in Midwest 185 GW. Total in East is 35 GW. Scenario 2, 20% wind penetration – “Hybrid, with Offshore”: Some wind in Great Plains is moved east, with capacity increased in PJM, NYISO, and ISO-NE. Offshore development at 16 GW in the Northeast and Mid-Atlantic. Four EWITS Scenarios:  Four EWITS Scenarios Scenario 3, 20% wind penetration – “Load-weighted Wind Development, Aggressive Offshore”: More wind near east load centers, even more off-shore locations for wind. Scenario 4, 30% wind penetration – “Aggressive On- and Off-shore”. More of everything. Lots (80 GW) of offshore is needed, and wind in MISO, MAPP, and SPP goes back up to 188 GW. 20% wind Scenarios:  20% wind Scenarios 30% Wind Scenario:  30% Wind Scenario EWITS Scenario 1 Generation Siting:  EWITS Scenario 1 Generation Siting EWITS Scenario 2 Generation Siting:  EWITS Scenario 2 Generation Siting EWITS Scenario 3 Generation Siting:  EWITS Scenario 3 Generation Siting EWITS Scenario 4 Generation Siting:  EWITS Scenario 4 Generation Siting Key Task- Develop Transmission Plan :  Key Task- Develop Transmission Plan JCSP reference future and 20% wind and 30% wind scenarios Analyze transmission alternatives for wind scenarios 765 AC and HVDC Transmission creates benefits in every analysis Slide18:  Joint Coordinated System Plan Overlay – 20% Wind Scenario Reliability Analysis:  Reliability Analysis GE MARS for Monte-Carlo based chronological reliability simulation Objective: Calculate wind generation ability contribution to meeting demand Cooperation between regions smoothes variation, lowers costs Hourly Modeling Intra-Hour Impacts Downloading EWITS Wind Data http://wind.nrel.gov/public/EWITS/ :  Downloading EWITS Wind Data http://wind.nrel.gov/public/EWITS/ Download Time-series Data All data (using ftp site) EWITS ftp site (ftp://ftp2.nrel.gov/pub/ewits) Instructions for ftp   Data for individual sites using interactive website EWITS Interactive Website   Frequently-Asked Questions (FAQs) about time-series data EWITS FAQ Downloading EWITS Wind Data EWITS Interactive Website / :  Downloading EWITS Wind Data EWITS Interactive Website / Your Input is Important! :  Your Input is Important!
