Kenedy wind power production is complimentary to serving ERCOT load during on peak periods.
West TX wind power production is notcomplimentary to serving ERCOT load during on peak periods.
The Texas Southern coast’s peak production occurs when energy demand is the greatest, making Kenedy an ideal candidate for wind development.

• Environmental Assessment or Environmental Impact Statement may be required
• U.S. Army Corp of Engineers permit or no action letter relating to wetlands
• Federal Aviation Administration no hazard determination
• Texas Historical Commission & U.S. Advisory Council on Historic Preservation: archaeology/cultural resource studies
• Department of Transportation coordination on load restrictions
• Texas Commission on Environmental Quality: construction storm water permit, Texas pollution discharge elimination permit (TPDES), storm water notice of intent & pollution prevention plan (SWPPP), spill prevention counter measures and control plan (SPCC), concrete batch plant air permits

Gulf Wind Government Consultations• Met with the U.S. Fish and Wildlife Service (USFWS) Director and Southwest
Regional Director • Met with numerous USFWS biologists and other USFWS personnel • Conducted two site visits for USFWS • Conducted two site visits for U.S. Army Corp of Engineers • Consulted with U.S. Army Corp of Engineers, used LIDAR technology
USFWS April 9, 2008 Letter • “The piping plover, interior least tern, and brown pelican are listed species
known from Kenedy County that are not predicted to be impacted by the project. Interior least terns and piping plovers are not anticipated in the project area, and brown pelicans are not expected to regularly occur in the project area and are being delisted.”
• “….Based on our meetings, conversations, the April 9 report, and the measures being implemented, we believe the potential for taking a listed species has been minimized.”
20
Expert Consultants
• SWCA Environmental Consultants: conducted ecological & avian assessments, wetland evaluation, storm water planning, hydrology analysis, biological surveys, threatened & endangered species surveys, archeological study
– No material impact to avian populations– No federal threatened or endangered species
habitats of concern in project area – USACE confirmed project layout does not
require federal actions or permits
• Curry & Kerlinger, LLC: conducted avian risk assessments
– No impact of biological significance
21
Wetland Avoidance
• Project designed to avoid all wetlands (jurisdictional and non-jurisdictional) –all turbine pads, roads, and other facilities located in uplands
• Roads are built on top of surficial sand layer
• Due to permeable surficial sand layer, surface water runoff occurs only during severe storms & hurricanes
• Culverts placed as appropriate to maintain existing drainage (as is case with the existing road network)
• Neither turbines pads nor access roads, nor any other facilities, will have a discernible effect on surface or groundwater

Endangered Species Summary
• Ocelot– No sightings ever recorded– No suitable habitat– Measures taken to avoid collision risk:
- Speed limit of 25 mph - Mowing along road shoulders- Construction crew training
• Piping Plover– No sightings in 3 years of surveys– No suitable habitat within project boundaries
• Northern Aplomado Falcon– No sightings; no nests– Inappropriate habitat– Predator load– Safe Harbor Agreement
24
State-of-the-Art Avian Radar Technology
• DeTect is a world leader in development, deployment and support of radar systems for bird strike avoidance, avian risk assessment and migratory research
• More than 3 years, 6 migration seasons, of radar observation data recorded onsite; 1.5 years continuous 24/7 radar data collection
• Large majority of migration occurs above the heights of the wind turbines
• Low altitude avian flight patterns correlate to low wind speeds where the wind turbines are usually not operating
• Developed mitigation plan based on low visibility and high passage rate Photo: Avian Radar at Kenedy Ranch, Babcock & Brown

Avian Risk Mitigation System
MERLIN to be operated as Risk Mitigation System:
•Act as "early warning system" continually monitoring birds approaching wind farms
•MERLIN SCADA software will automatically idle turbines when risk conditions detected
• Derivative of DeTect technology used by USAF to monitor aircraft risk at airfield
• MERLIN will restart turbines when risk has abated
•First such implementation of this technology at a wind farm
