DOE Municipal Solid-State Street Lighting Consortium

ssl.energy.gov 2 | Solid-State Lighting Program

The Landscape in 2010

• Growing interest in LED streetlights fueled by ARRA funding, energy mandates

• The competition: mature but not well understood • Problems with conventional technologies “accepted”

by users – Outputs highly variable

and often not as advertised – Maintenance costs often

not well documented – Overlighting fairly common

• LED technology still evolving – High costs – Wide variation in product

quality

The Opportunity

• Aging infrastructure due for replacement – Average age: >25

years

• Opportunity for huge energy savings

The Consortium

• April 2010: DOE launches national consortium to leverage efforts of multiple cities evaluating LED streetlights – Accelerate learning curve – Avoid duplication of effort – Minimize risk

• Members share experiences through regional meetings, webcasts, web-based discussion forums

• Build repository of field experience, data, tools

DOE SSL Program Strategy

• R&D projects drive performance improvements, greater efficiency, cost reductions

• Market programs provide unbiased information, education, tools – Information from CALiPER, GATEWAY, and Consortium

feeds back to R&D priorities

The Landscape in 2012

• Membership: More than 350 municipalities, utilities, and government agencies

• Workshops: 10 regional workshops provide forum for education, collaboration on specifications and tools

• Demonstrations: Kansas City, MO; Sacramento, CA; Philadelphia, PA; Seattle, WA

• Resources: Model Specification for LED Roadway Luminaires; Retrofit Financial Analysis Tool

• Project scope: 41,000 streetlights (to date: 20,000)

• Total budget: $18 million (to date: $8 million)

• Sources of funding: – ARRA/EECBG grant: $1 million (2,439 LED streetlights/

769,439 kWh reduced) – City of Seattle: $17 million

• Energy savings target: 12,929,720 kWh

• Energy savings to date: 6,307,700 kWh

• Estimated simple payback: 7.6 years

Los Angeles Case Study

• Costs saved to date: $2.5 million (target: $10 million annual energy savings)

• Program start date: February 2009 • Project scope: 140,000 streetlights (to date: 72,000) • Total program expenditures: $57 million (to date: $20 million) • Source of funding: Utility energy efficiency loan ($40 million), repaid

with savings from annual streetlighting budget ($17 million) • Energy savings: 61.2% (original goal: 40%) • Annual energy savings target: 68,285 MWh • Current energy savings rate: 27,964 MWh • Estimated simple payback: 7 years

Model Specification for LED Roadway Luminaires

• Developed in response to demand from Consortium members and others

• Establishes common language and framework

• Serves as checklist to minimize errors and omissions

• Allows for customization by each adopting entity

Model Spec: Pocahontas, IA

• Iowa Association of Municipal Utilities (IAMU) joint purchase

• Project scope: 280 streetlights

• Final project cost: $192,375 – ARRA/EECBG grant of $81,826.04 paid up to 266 streetlights

• Projected annual energy savings: $14,062.87 and 234,381 kWh

• Estimated simple payback (without maintenance): 13.7 years

Model Spec: Kansas City, MO

• Ideal use of Model Spec • In 2010, KCMO began using Model Spec draft to evaluate

LEDs for total system retrofit • Identified 9 products from 7 vendors; each worked for

the application • Major spec contributions:

– Performance based calculations based on typical roadway layouts—true replacement for existing HPS

– Direction for LED color—CCT (4500K for KCMO) – Specifying LED/system reliability – Surge protection recommendations – RFP evaluation—trust, but verify, field testing

ssl.energy.gov 13 | Solid-State Lighting Program

Retrofit Financial Analysis Tool

• Evaluates costs and benefits of LED conversion • Provides detailed analysis:

– Annual energy and energy cost savings – Annual maintenance savings – Annual greenhouse gas reductions – Simple payback, IRR – Net present value
