Industry Reports and Research
This table provides an overview of the incentives offered by DLC members for lighting controls. The summaries are intended to help program managers compare offerings, and to inform manufacturers of incentives across DLC member territories.
The incentive program summaries are intended to help provide a comparison of horticultural lighting program offerings and incentive levels across DLC Member territories. This table serves as an overview of the territories covered by DLC Members.

Completed in partnership with the Northwest Energy Efficiency Alliance (NEEA), this research builds upon the DLC's 2017 study, Energy Savings from Networked Lighting Control (NLC) Systems. The results not only improve existing NLC energy savings estimates, but also provide more in-depth savings analyses, such as savings estimates from NLC systems with and without luminaire level lighting control (LLLC), and savings estimates from high-end trim compared to other control strategies.
- Portfolio-level estimate for NLC energy savings is 49%, but NLC systems with LLLC showed overall higher savings.
- Access to NLC data varies from manufacturer to manufacturer, so there is an opportunity for efficiency programs to drive the sharing of NLC data.
- Energy efficiency programs should standardize reporting guidelines, and manufacturers should consider developing administrator-specific reporting functionality to support the energy efficiency program data intake process.
This report explores the current interest in networked lighting controls (NLC) and the benefits various stakeholders can attain from championing interoperable systems. Three actionable use cases work to show why interoperability is a core component for ongoing operation of energy savings programs and is essential for the long-lasting relevance of NLCs.
- Build a common understanding about NLC interoperability.
- Explore three use cases: External Systems Integration, Load Shedding and Demand Response, and Energy Monitoring.
- Identify design criteria and questions to ask when specifying interoperability related to NLC systems.
New research from the Alliance to Save Energy and the DLC indicates that state efficiency policies routinely understate energy savings potential of lighting systems, leaving substantial savings on the table. Key recommendations of the report include shifting energy efficiency programs toward incentive strategies that promote LED lighting and networked lighting controls (NLC) as a system, which could increase NLC lifetime savings by 22% and help shave peak demand.
- Increase the focus on lifetime savings instead of annual (first-year) savings to better represent the impacts of policies and programs.
- Characterize networked lighting controls as a single LED + NLC system measure within TRMs to minimize cost-effectiveness challenges, maximize lifetime and peak savings, limit stranded savings, and encourage integration with other building systems
- Promoting LED + NLC as a system can help utilities immediate energy savings objectives and set the stage for the future of grid-interactive efficient buildings (GEB).
