Alternative Fuel Corridor Signage on the Horizon for Louisiana

    Drivers heading down Louisiana's interstate corridors will soon see signs advertising fueling stations with alternative fuels along their commute.

    In 2018, Louisiana submitted a proposal to the FHWA to have Alternative Fuels Corridor signage installed along our interstate highways. Louisiana Department of Environmental Quality says in their March 2019 newsletter, "LDEQ worked closely with Louisiana Clean Fuels and Capitol Region Planning Commission to complete the states’ proposal to the Federal Highway Administration (FHWA). LDEQ is proud to announce Louisiana now joins 34 other states where the FHWA has approved Alternative Fuels Corridors. FHWA and participating states hope the Alternative Fuel Corridors will bring together stakeholders like state agencies, utilities, alternative fuel providers and car manufacturers to promote the advancement and use of alternative fuels." Multiple corridors have been approved for signage for the following fuels in Louisiana: compressed natural gas (CNG), liquified natural gas (LNG), and liquified propane gas (LPG).

    On March 18, 2019, Louisiana Governor John Bel Edwards posed with several cabinet members in front of one of the new Alternative Fuel Corridor signs to celebrate their coming installation. The signs will be installed along interstates I-10, I-20, and I-49 to mark fueling locations for propane, LNG, and CNG. Having signs along Louisiana's interstates will enable drivers to quickly and easily locate fueling stations for alternative fuels.

    DEQ quoted comments from Gov. John Bel Edwards: “These signs will provide vital information to drivers of alternative fuels vehicles who are traveling Louisiana interstates...In the future, we will look back on this as one of Louisiana’s first steps toward a cleaner more energy efficient transportation infrastructure.'”

    Though Louisiana has not yet been approved for electric vehicle charging signage, LCF is currently working on a DC Fast Charger Master Plan to propose locations for DC Fast Chargers along Louisiana's interstates with the aim of establishing an EV charging corridor and adding EV signage to our alternative fuel corridor signage. Currently, there are only 3 DC Fast Charger in the state of Louisiana that are not Tesla-exclusive. Under the FHWA guidelines, DC Fast Chargers must be spaced a maximum of 50 miles apart, each within 5 miles of the interstate in order for the corridor to be eligible for signage.

    Moving forward, LCF is excited to see the progress Louisiana has made in recognizing and encouraging the use of cleaner fuel options in our state's transportation. LCF's mission includes a commitment to supporting local actions to diversify transportation fuel options in the name of advancing the nation’s environmental, economic, and energy security, and the establishment of an alternative fuels corridor with corresponding signage is a major step in the direction of that diversification.

    For more information, see DEQ's March 2019 newsletter write-up of the corridor signage.

    Louisiana DC Fast Charging Corridor Master Plan

    Updated 12/27/2018 - With the exception of Tesla owners, electric car owners in Louisiana currently do not have an adequate charging infrastructure along our interstate corridors. While the daily commute for a typical EV owner in their hometowns may be workable, taking their EV on road trips can often be a hassle. Louisiana Clean Fuels is currently looking for additional partners to help complete a master plan to create a well-designed charging infrastructure along our interstate corridors. The plan, explained below, will provide future site hosts with a business case to install EVSE at select sites across our state. We will also work with our stakeholders to secure funding to help offset the cost of installation. Support this project with a donation today!

    On November 30, 2017, Louisiana submitted its proposal to the Federal Highway Administration (FHWA) for alternative fuel corridors. The state submitted proposals for three fuels along specific sections of our interstate system. On March 8, 2018, the state received notification of the approved signage-ready and signage-pending corridors. The fuels that received approval for corridors signage in Louisiana are CNG, Propane and LNG. The Louisiana Department of Environmental Quality (LDEQ) and Louisiana Clean Fuels (LCF) will now begin work with the Louisiana Department of Transportation and Development (LDOTD) to have the necessary signage produced so that the corridor is clearly marked.

    The Opportunity:

    The only fuel that did not qualify for signage was charging for electric vehicles. Under the FHWA guidelines, DC Fast Chargers must be spaced a maximum of 50 miles apart, each within 5 miles of the interstate in order for the corridor to be eligible for signage. To jump start the development of an electric charging corridor along our interstate system, LCF proposes creating a DC Fast Charging Master Plan for the state of Louisiana.

    The Plan:

    LCF has assembled a team of data experts, OEMs, EVSE experts, electric utilities and MPOs to begin work on a two-part plan. The first part of the Master Plan is to create the business case for potential DC Fast Charging sites that is backed up with comprehensive data which will aid in identifying the best locations for DC Fast Chargers along our interstates. LCF will collect highway data, economic data of the potential sites, and vehicle data from multiple sources along with existing infrastructure. The data will be used to conduct analyses and modeling that will reveal optimal DC Fast Charging sites in Louisiana.

    The second part of the Master Plan process is to conduct regional outreach meetings in the different planning commission / MPO territories across the state. Both LCF and LDEQ will host these round table meetings with area businesses, utilities, and elected officials in order to facilitate local acceptance and demand for EVSE charging infrastructure along their critical corridors.

    EVSE Site Ranking Criteria

    LCF will prioritize locations around the state for possible DC Fast Charging EVSE installations utilizing the Sawatch EVSE siting analytics and site ranking criteria such as, but not limited to:

    • Access to shopping and dining
    • Access to a recreational facility
    • Safety (well-lit, low-crime)
    • Electrical Capacity (408 volt, 3-phase power)
    • Within 5-miles of an Interstate
    • Preferred by utility service provider
    • Preferred by local government
    • Co-located with other Public EVSE
    • Co-located with Tesla Charging
    • Co-located with a hotel
    • Publicly accessible parking garages

    How can you help?

    Sponsors are being sought to fund the Louisiana Statewide DC Fast Charging Corridor Master Plan. All funds will go directly to paying for Phase 1 of the plan: acquisition of data sets and fees paid to LCF’s contractors for the modeling and analysis of potential sites along our interstate corridor. The completed plan will provide a business case for potential DC Fast Charging host sites. All sponsors will get access to the final plan for three months before the Master Plan is published. Additionally, entities from all sponsorship levels will be invited to participate in the Master Plan committee meetings, regional outreach meetings, and will receive recognition in all press releases and events related to promotion of and/or completion of the study.

    Thank you to our sponsors!
