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?

Offshore Wind: 

Offshore Wind Great resource Well correlated with load and close to load centers More expensive!

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.
