  1. National Grid New York Non-Wires AlternativesERCOT Meeting Stacey Hughes – New Energy Solutions November 17, 2017

  2. Agenda NWA Project Development Process Project types RFP Process Active Projects/Lessons Learned Kenmore Baldwinsville Old Forge Fayetteville/Gilbert Mills

  3. Non-Wires Process • New York Utilities (JU) created consistent suitability and sourcing process following Reforming the Energy Vision language and concepts • Common job types (Reliability, Loading), project costs and need timing • Similar request for proposal process • NYS PSC wants vendor involvement “market animation” • Provide vendors with the area engineering problem and general information about the area

  4. Non-Wires Process, Continued • Proposal assessment • Scoring template • NWA team scores proposals based on general criteria • Shortlist affordable/viable proposals • Engage shortlisted vendors • Apply BCA • Choose most affordable/viable proposal

  5. Kenmore • Identified for the DLM program order in 2014 • ThinkEco DR solution 2015 – added Connected Solutions in 2016 and Nest Rush Hour Rewards in 2017 • Solicited 1,000 customers for the coolControl, ConnectedSolutions and Nest under the DLC program in Kenmore • Area lacks C&I customers • Adding Battery Storage via the Storage Order – NYS PSC Case 17-E-0238 Kenmore

  6. Kenmore – Lessons Learned • AC based DR reductions in Buffalo are difficult and expensive • Window AC reductions even more so • Small commercial difficult to engage • Large C&I needed for successful DR programs • Working on partnership with NYSERDA and National Fuel Gas to incentivize building envelope EE measures for baseload reduction and controllable T-Stats for DR Kenmore in July

  7. Baldwinsville • Baldwinsville and initial 7 NWA projects identified using former screening criteria • 6 MW - MWh violation Traditional upgrade $6M • NWA processes built on Baldwinsville • Sourcing • Review/ranking • Benefit Cost Analysis • BCA results very low unlikely it will move forward – will review with NYS PSC Staff Lysander and Sorrel Hill Circuit Map

  8. Baldwinsville Proposal Overview Received 11 proposals Four demand response proposals – not viable – held for partnership opportunities One portable storage solution –cost prohibitive – not shortlisted but the technology is promising Six static storage proposals –all too expensive 8

  9. Baldwinsville Lessons Learned • MWh violation for Baldwinsville - dictated need was too difficult to solve • Any day of the week • 7 consecutive days • 6-11 hour dispatch duration • DR proposals were not viable • Storage proposals were too expensive given the MWh need • BCA process built on Baldwinsville • New DERs are added as they are proposed • Changed the RFP language/instructions to reflect BCA input needs • Proposal review process is time consuming

  10. Old Forge Large reliability project located in the Adirondack Park 5 substations included in project area - 5 of our 15 worst performing Outages due to hit poles and tree damage Need immediate power injection to help combat power outages in the area – looking to bridge the time it takes our crews to respond and repair Market participation not likely to be feasible given the unpredictable need Additional difficulties assumed due to location in the ADK park Seasonal homes create challenges

  11. Old Forge Lessons Learned Working in the Adirondack Park more plausible then originally thought Local officials need to be informed and remain informed Added traditional cost estimate for this project to the RFP - experimenting with adding and leaving out

  12. Fayetteville • Small project – 200 kW relief needed • Overloaded ratio bank • 162 customers located downstream of ratio • Received one proposal • Natural gas generator

  13. Fayetteville Lessons Learned Ratio bank projects may be too small JU may want to raise the minimal project cost depending on these results and that of a few other small sized project solutions Procuring with another project was positive

  14. Gilbert Mills • Overloaded station transformer/MWh violation • Received 4 proposals • 1 Natural gas generator • 1Energy storage with DR • 1 Zinc flow battery storage • 1 solar plus storage • Plan to move all four forward to BCA if responses to request for information meet system needs

  15. Gilbert Mills Lessons Learned • Provided high level natural gas availability maps in RFP • Helped pull in a new technology – NG generators • May be beneficial to both parties to provide optimal locations for DERs (Heat Maps under development) • Clearer direction in RFP seems to pay off • Better proposals • All determined viable after first review
