Revision Schedule and Listing Fees

Revision Schedule and Listing Fees

Schedule of Technical Requirements Revisions

  • The DLC revises the Networked Lighting Controls Technical Requirements annually, with final revisions completed and released on June 1st of each year.
  • Each Technical Requirements revision is distributed through the DLC Stakeholder Input Process and comments will be considered for each revision. This process begins in January of each year to allow sufficient time for stakeholder input for each proposed revision.
  • Manufacturers must requalify and relist their systems each year, in line with the annual Technical Requirements revision schedule. 
  • Grace Period Policy: A one-year listing grace period will be provided for systems that have been qualified under a previous version of the Technical Requirements but do not meet revised requirements. This grace period provides a period of one year for manufacturers to revise their current systems or offer a new system that qualifies according to the most current version of the Technical Requirements.


Delisting and Next Release

NLC Version 3.0 delisting:

NLC3 listed systems will be delisted on October 31, 2020, unless they have been updated to NLC5 with cybersecurity.

NLC Version 4.0 delisting:

Any NLC4 systems that have not been updated to NLC5 (that is, that do not have DLC-recognized cybersecurity) will be delisted on February 28, 2022. (This date has been extended from October 31, 2021 because of COVID-19-related complications in product development.) Before February 28, 2022, if a new system applies without cybersecurity or a listed system reapplies without cybersecurity, the system will be listed as NLC4 until proof of cybersecurity is submitted. When cybersecurity proof is accepted by the DLC, the listing version will be updated to match the application version most recently submitted for that system.

Timeline of the next Technical Requirements release: 

The current plan for the timeline of future releases is shown below. The DLC is considering whether to extend the validity timeframe of NLC5 and delay the release of NLC6. Whether or not that occurs, delisting of products without cybersecurity will occur on February 28, 2022. The DLC will advise manufacturers and utilities no later than January 2021 of any updated timelines.

Fee Amounts and Structure

To coincide with annual Technical Requirements revisions, the DLC requires an annual qualification and listing fee for each system to be qualified and listed on the Networked Lighting Control QPL. Systems must be submitted for review and requalification each year and the fee must be paid annually.

After a system has been initially qualified, it will be listed until the following May 31 with a “fully qualified” status. On June 1, the system will enter an “under renewal review” status during which manufacturers must file a new application for the system. In order to be requalified and relisted for the next year, there are two scenarios:

  • Scenario 1: The resubmitted system meets the revised Technical Requirements. If after review the system is found to meet the revised requirements, the system will be relisted through the following May 31 and eligible for an additional one-year grace period beyond that date. The system will have a “fully qualified” status according to the most current Technical Requirements.
  • Scenario 2: The resubmitted system does not meet the revised Technical Requirements. If after review the system is found not to meet the revised requirements, then the listing can be renewed once until the following May 31 in accordance with the one-year grace period policy. The system will have a “fully qualified” status according to the prior Technical Requirements. After the one-year grace period, the system will be removed from the QPL unless it is modified or replaced by a new system that meets the revised Technical Requirements.

Please note that in both scenarios above, the annual qualification/listing fee must be paid each year. Previously-qualified systems that do not meet revised Technical Requirements will be delisted after the one-year grace period. This grace period gives manufacturers one year to modify their system or develop a new system to comply with revised Technical Requirements. Systems that are delisted after the grace period will still be searchable by DLC Member utilities and rebates/incentives may be paid for them at the discretion of the DLC Member utility.

New systems that have not been previously qualified and are submitted for qualification between Technical Requirements revisions (i.e. after June 1 of each year) will owe a pro-rated fee based on the remaining time in the year before the next Technical Requirements revision according to the following schedule: 

Applications Received Single Interior or Exterior System - New Applicant Single Interior or Exterior System - Renew Applicant Each Additional Product Listed (incl. Private Label)
July 1, 2020 – September 30, 2020 $15,000 $15,000 $5,500
October 1, 2020 – December 31, 2020 $12,000 N/A $5,500
January 1, 2021 – April 15, 2021 $9,000 N/A $5,500
April 16, 2021 – June 30, 2021 N/A N/A N/A

Annual renewal fees are as follows:

Annual Renewal Fees First Product Listed Each Additional Product Listed (incl. Private Label)
Invoiced in July, due in 30 days. (Potential delisting after 90 days unpaid) $15,000 $5,500

The DLC offers reduced fee amounts for family member and private label systems. Family member systems are child or derivative systems of a parent system that may offer small differences in feature sets and/or characteristics, but are otherwise identical to the parent system. For complete definitions of family member systems and private label systems, see the System Definitions page. Manufacturers interested in preparing a family set of applications should contact to confirm a plan before completing the applications.

Manufacturers may update information about a listed system more frequently at their discretion in 3 cells of the QPL at no cost, and additional cells at $200 per cell.

Why Listing Fees?

Qualification and listing fees are required for review of system applications and updating of system information displayed on the QPL. These fees support the overall implementation and annual revision of the Networked Lighting Controls QPL. The DLC seeks significant energy savings for its Members and their customers through networked lighting control systems. Listing fees are leveraged with grant funding and additional funding provided by DLC Member utilities and energy efficiency programs to continually drive energy efficiency through the QPL and achieve widespread adoption of lighting control systems in the market.

Backed by financial incentives of DLC Member utilities, qualification on the QPL creates new opportunities for product differentiation and delivery of customer value. The DLC aims to support market expansion and to provide a single point of entry for manufacturers to participate in energy efficiency programs.
