Objectives of Eastern Wind Integration and Transmission Study (EWITS)
• Evaluate the power system impacts (operating due to variability and uncertainty of wind; transmission; reliability) associated with increasing wind capacity to 20% and 30% of retail electric energy sales in the Joint Coordinated System Plan region (MISO/PJM/SPP/TVA) by 2024;
• Build upon prior wind integration studies and related technical work;
• Coordinate with Joint Coordinated System Plan (JCSP) and current regional power system study work;
• Produce meaningful, broadly supported results through a technically rigorous, inclusive study process.
Key Issues & Questions include
• What are the benefits from long distance transmission that accesses multiple wind resources that are geographically diverse?
• What are the benefits from long distance transmission that move large quantities of remote wind energy to urban markets?
• What are the cost/benefits of remote wind resources that require transmission versus lower wind speed local wind resources?
• How much does geographical diversity help reduce system variability and uncertainty?
Key Issues & Questions include
• What additional system operational impacts and costs are imposed by wind generation variability and uncertainty?
• What is the role and value of wind forecasting?
• What benefit does balancing area cooperation or consolidation bring to wind variability and uncertainty management?
• How does wind generation capacity value affect reliability?
Wind Integration Methods & Best Practices
• Capture system characteristics and response through operational simulations and modeling;
• Capture wind deployment geographic diversity through synchronized weather simulation;
• Match wind output with actual historic utility load and load forecasts;
• Use actual large wind plant power statistical data for short-term regulation and ramping;
• Examine wind variation in combination with load variations.
Wind Integration Methods & Best Practices Cont.
• Utilize wind forecasting best practices and combine wind forecast error with load forecast error;
• Examine impacts of Balancing Area consolidation and fast markets.
Key Tasks- Eastern Wind Integration & Transmission Study
• Three main tasks1) Mesoscale wind resource modeling and development of wind power plant outputs
2) Transmission Analysis (with JCSP)
3) Wind integration study
Key Tasks- Mesoscale wind resource modeling
• Develop high quality wind resource data sets for the wind integration study area (mesoscale modeling, 3 years)
Key Tasks- Eastern Wind Integration & Transmission Study
• Identify wind power generation sites for 20% & 30% wind energy scenarios– More than 300 GWs of
total wind power data generated in time series for 3 years!
– 135 GWs for 20% energy and 200 GWs for 30% energy scenario
Key Tasks- Transmission Analysis
• Develop transmission plan (coordinated with JCSP)– Run hourly
dispatch/market models
Joint Coordinated System Plan (JCSP)
• The 2007/2008 Joint Coordinated System plan will include MISO, PJM, SPP, and TVA
• The JCSP will perform a long term planning study incorporating both economic (2024) and reliability (2018) analysis of system performance for the combined four JCSP areas
• Collaboration with the parallel DOE Eastern Wind Integration & Transmission Study will provide underlying assumptions for generation scenarios
• Scheduled to be completed December 2008
Key Tasks- Eastern Wind Integration & Transmission Study
• Evaluate operating impacts and associated costs– Regulation– Load Following– Unit Commitment
• Evaluate reliability impacts (ELCC/LOLP)

Technical Review Committee (TRC)
• A TRC will be formed with regional and national technical experts on wind generation and power systems analysis to help guide and review the study
• The TRC will review and provide feedback on key assumptions, methods, and preliminary results
• It is anticipated that the TRC will meet quarterly throughout the study
Preliminary Schedule
• Nov 07 – Feb 08 Study Development and Stakeholder input
• January 2008 Award Wind Mesoscale Modeling Contract
• February 2008 Award Wind Integration Contract
• Jan – Oct 2008 Develop Wind Data Sets
• April – Dec 2008 Develop Transmission Plan in Coordination with JCSP
