1 LED STREET LIGHT CONVERSION: How a Field Audit and the Community Managed RFP Work September 18, 2017

2 Mid-Hudson Street Light Consortium Funded by NYSERDA Cleaner Greener Communities through mid-2018 Survey and Consortium formation Assessment: LED Street Light Conversion in New York A Common Sense Guide for Local Governments in the Mid-Hudson Region Steering Committee Procurement Aggregation Turnkey/Community Managed 2

3 Questions To Be Addressed Today What are the steps to LED street light conversion? What is the timeline and sequence of events to work with the Consortium? What does my municipality have to do, and what commitment must we make? Why is a Field Audit important, and do we have to do all the steps? What if I don t have a Green Team to help with this? What is a Participant in the Community Managed Request for Proposals? What is a Piggybacker in the Community Managed RFP? How can our muni determine which is better: Community Managed or Turnkey? 3

4 MHSC Services Excel workbook creation for RFP Participants Guidance in how to use workbook Training re Field Inventory Street light system design guidance 4

5 Steps/Timeline for RFP Participation By Nov. 15: Commit to participate with Resolution or Letter Provide existing light inventory to MHSC and any required addenda to RFP Complete review by municipal attorney If need be, pass local Best Value Law Designate 1 representative to participate in bidder selection with MHSC Within one year: Determine whether to contract with selected Bidder 5

6 Steps: Purchase Existing Lights/Convert to LEDs Must be synced with LED conversion Request an estimated purchase price from utility Request a Billing Audit from 3 rd party providers Conduct Field Audit Design new LED street light system Enter into aggregated purchase or pursue solo approach 6

32 LED Replacement Wattages for Common Street Light Types/Wattages 32 Assumes an efficacy for the LEDs of at least 100 lumens per watt. The recently approved utility replacements for the 70-watt HPS (the most common fixture) range from watts.

34 Clean Energy Communities Program Municipal Finance Streetlight acquisition and/or conversion may be funded by a municipality through issuance of municipal debt bonds or BANs. Considerations/Characteristics include: BANs are low cost and short-term. Bonds have low interest rate but high transaction costs. Tax Exempt Municipal Lease Interest 2.5% to 3% days to process-no transaction costs Little to no Prepayment Penalty Subject to Annual Appropriation Funds Held in Escrow 34

36 Marbletown Case Study 36 Marbletown completed inventory of 80 lights in 3 weeks. 5 volunteers performed data collection; 90% done by 2 of them. Volunteers spent an average of 20 minutes at each light. Data entry, checking, and mapping done by single computer- savvy volunteer.

38 Billing Audits 38 Utility s inventory of streetlights is often inaccurate. Lights in utility inventory no longer exist in field, belong to another entity, or wattages in field do not match inventory. Technology changes are not recorded, i.e MV to HPS or LED.

39 Equipment Needed By Volunteers 39 Smartphone or tablet with GPS capability - OR- Auto nav system/hiking GPS Digital camera Tape measure Ability to record observations and keep track of pictures.

40 Data Collection 40 Essential and easy to collect inventory info: Utility pole number Light fixture type (HPS, MV) Size of light (Watts) GPS location or street address Condition of equipment Pedestrian activity and adjacent land use road safety conditions (intersection, line of site, pedestrian- vehicle conflict area)

41 Location 41 Use smart phone or auto/personal navigation system to determine GPS coordinates. If volunteer does not have ability to collect GPS data, street address can be used with Google Maps to accurately pinpoint light. If using smartphone app, location data is collected automatically.

42 Correcting Inventory Data 42 Volunteers recorded data in a spreadsheet and cross- referenced with utility data. Lights over driveways and commercial parking lots are likely private area lighting. Some lights may not exist or have different fixture types. Billing mistakes are common and grounds for refund. Do not correct inventory without first seeking refund. Contact utility and ask about specific discrepancies and fixing broken lights.
