2. Agenda  Introductions  Recap –About Advisory Working Groups (AWG) –Project Overview & Update –AWG Recap  Tonight’s topics –Project Benefits (short and long term) –Design Factors  Planning for next AWG 2

3. Tonight’s Speakers  Bob De Meyere – Cricket Valley Energy (CVE) –Project Manager – Cricket Valley Energy Center  David Klinch – Epsilon Associates, Inc. –Project environmental consultant  Nora Madonick – Arch Street Communications –Public information and outreach 3

4. What is an Advisory Working Group (AWG)?  Informal, unofficial opportunities for the public and project experts to share information and ideas  Not required by the public process – additional outreach by Cricket Valley Energy – comments are not part of the official public record  No specialized knowledge is needed – technical information will be presented in plain language  If you are attending as a member of an organization, please share what you learn tonight with your members  Announced via website, postcards, email blast, calendar listing, posters, advertising, posting on town websites 4

5. AWGs are self-determined.  The group:  Chose the topics for tonight’s meeting  Requested use of microphones as needed  Requested longer question/answer period  All meeting materials will be posted on the web following tonight’s meeting  Please visit cricketvalleytransmission.com for updates and to sign up for email notifications 5

6. Recap: Project Overview  Cricket Valley Energy is a 1000 MW energy generation facility in Dover, NY  Fully approved and permitted  Completed State Environmental Quality Review (SEQR) process  Restoration of abandoned industrial site 6

7. Recap: New York Independent System Operator Requirement  CVE has been required by NYISO to increase transmission/transfer capacity, redundancy, and operational capacities by:  Funding and installing 14.6-mile transmission line in existing right-of-way between CVE in Dover and Con Edison substation in Pleasant Valley  Reconductoring 3.4-mile segment of existing line between CVE substation and the NY/CT border  Upgrading Pleasant Valley substation (within existing footprint) security/communication infrastructure 7  NOT part of any of the following transmission line projects: NY Transco Edic to Pleasant Valley; NEXTERA New Scotland to Pleasant Valley; North American Transmission; or Boundless Energy Transmission

8. Project Status 8

9. AWG Recap (October meeting)  Visual Impact  The CVE team identified an option to reduce the proposed pole height by as much as 40 ft by using H-frame poles, replacing monopoles in certain key locations, and modifying the original design of the monopoles  Design changes have been submitted for approval to Con Edison  Underground Construction −Based on the significant environmental and other potential impacts, the underground option failed to satisfy the project design requirements set forth by Con Edison and NYISO 9

10. AWG Recap (October meeting)  Noise  Restrictions will be in place to limit noise-producing construction activity to standard daylight working hours  Short intervals of work along the right-of-way over a total schedule of 24 months  Standard construction equipment, such as drill rigs, rough terrain cranes, cable pulling rigs  Helicopters (heavy lift and light duty)  Trucks to deliver materials, bring workers to and from active construction areas 10

11. AWG Recap (October meeting)  Safety −Safety is our highest priority −CVE will address all considerations in order to meet safety standards, including: construction, monopoles, and operations −Clearances: vegetation and trees, if not properly maintained, can be a source of outages −Aviation: structure heights, locations, and lighting in accordance with FAA requirements will ensure safe operation of the transmission line in Sky Acres Airport area 11

12. Benefits (Short & Long Term) Tonight we will cover:  Labor and workforce  Sourcing local business  Low impact design  Restoration of impacted areas 12

13. Labor and Workforce 13  Direct and indirect positive impacts to regional economy of over $1 billion over 20 years  Power Plant −Up to 750 direct construction jobs – averaging around 300 per year for the estimated 3 year construction period (Approx. $147 million) −More than 1500 indirect, and induced jobs −56 direct, indirect, and induced jobs supporting operations (post construction phase)  Transmission Line −60 to 80 direct construction jobs −Up to 80 additional Indirect and induced jobs in support of project

14. Sourcing Local Business 14  Indirect and induced employment −Local purchases during construction  Materials and services  For construction work force (meals, fuel, incidentals, lodging, etc.) −Local services to support construction and operation  Sky Acres Airport and other sites to support construction  Tax Revenue to State, County, Towns, and School district

15. Low Impact Design 15  Minimal footprint −Proposed transmission line will be constructed entirely within the existing right-of-way −Existing Con Edison right-of-way is presently more than 90% free of tree growth −For safety and reliability, some trees along the southern edge of the right-of-way will be cleared in accordance with industry standard safety requirements (less than 8% of the total right-of-way area) −Construction to be limited  Pole locations – 4-5 per mile

16. Low Impact Design (continued) 16  Construction measures −Protective measures such as hay bale and silt fence barriers between the resource areas and work areas to prevent inadvertent impacts to wetlands and streams −Highly-trained construction monitors to oversee work; including particular attention to sensitive areas to prevent any damage to wetlands and streams along the right-of-way −Protection of threatened and endangered species habitats per DEC approval −Physical avoidance, time of year restrictions −Use of rock anchors in most locations −Selective use of helicopters to set poles

17. Restoration of Impacted Areas 17  Wetland restoration plan and remediation at CVE site in Dover  Transmission line – restoration of work areas  Natural buffers −Landscaping to screen the Pleasant Valley substation, along Rt. 44 −Natural tree buffer at CVE site in Dover

18. QUESTIONS 18

19. Design Factors Tonight we will cover:  Revised pole heights  Insulated cables  Ice and wind loads that can affect the line 19

20. Revised Pole Heights  Reviewed technical requirements ‒ National Electric Safety Code (NESC) ‒ Con Edison ‒ New York State Department of Public Service (DPS) 20

21. Revised Pole Heights  Key Considerations ‒ Con Edison phase-to-phase electrical clearance: 15 ft. minimum (displaced conductors) ‒ Con Edison phase-to-ground electrical clearance: 9 ft. minimum (displaced conductors) ‒ 35 foot electrical clearance to ground under maximum operating temperature of 180ºC (356ºF) ‒ EMF requirements  Distance to ground for EMF analysis: determined under winter normal temperature of 95ºC (203ºF)  For example: the span between CV-07 to CV-08 is 44 ft  EMF: Electric field < 1.6kV/m at edge of right-of-way  EMF: Magnetic field < 200 mG at edge of right-of-way 21

22. Why not use insulated cables?  Technically impractical for overhead high voltage transmission lines ‒ Insulated cables would be 8 -10 inches in diameter changing the weight from 2.5 lbs/ft to 44.7 lbs/ft ‒ Would require 3 cables for each phase – 9 cables total ‒ Requires cable bridge supports, abutments and additional wires to support the cable ‒ More massive and intrusive than overhead bare cables 22

23. What are the ice and wind loads?  Designs exceed NESC Code minimums  100-year wind loading of 25 psf wind pressure (100 mph) wind  100-year ice loading of 1” radial ice with a concurrent 8 psf (56 mph) wind  Unbalanced ½ inch ice 23
