Qualified Products Lists help identify energy-efficient technologies that meet defined performance standards, bringing clarity to a complex and evolving market.  

As new technologies enter the market, it can be difficult for consumers to identify products that are both efficient and meet their needs. A Qualified Products List (QPL) helps address that challenge by identifying products that meet a defined set of technical performance criteria. In addition to supporting consumers, the detailed performance standards that underpin a QPL provide valuable guidance to manufacturers on desired performance levels that support affordability and grid reliability. In these ways, QPLs encourage the supply and demand of efficient products.   

Some QPLs are highly specific and technical. In these cases, the QPLs are most often used by utilities, program administrators, designers, contractors and manufacturers to quickly identify products that align with energy-efficiency goals, incentive requirements or emerging market expectations. 

QPLs identify products that meet specific energy efficiency and performance thresholds for a given technology, like heat pump water heaters or high-efficiency clothes dryers, based on published specifications. Products on a QPL are not ranked or endorsed. The list establishes a clear, consistent baseline for what qualifies as a high-performing product and sends a signal to the market about expected performance.

Why QPLs are Important 

Assessing product performance can be complex and time-consuming. Specifications may be spread across multiple standards, and efficiency information is not always easy to interpret or compare. 

QPLs help simplify that process by offering a shared, transparent reference point grounded in technical review. 

By lowering the time and effort required to evaluate products, QPLs help: 

• Reduce uncertainty when selecting equipment 

• Support consistency across projects and programs 

• Increase visibility for energy-efficient products 

• Increase manufacturers interest in designing products to the QPL specifications 

Over time, this clarity helps efficient technologies move from early adoption toward broader market acceptance.

What Makes a Product Qualified?

Products included on a QPL are reviewed against published technical criteria, which may include efficiency metrics, performance characteristics, or other measurable standards. The goal is not to rank products or recommend specific manufacturers, but to establish a common baseline for performance. 

This reflects a core consideration in NEEA’s work: for new technologies to succeed, they must not only perform efficiently but also meet or exceed the performance of incumbent products.   
 
As technologies evolve and markets change, QPL criteria may be updated to ensure the lists remain relevant and useful. Heat pump water heaters offer a useful example: as the technology matured, NEEA’s Advanced Water Heating Specification added tiered criteria to identify products that met increasingly advanced expectations, including not just efficiency, but features like connected controls that can support demand response and other capabilities valued by utilities, installers and customers.

When and Why NEEA Develops QPLs 

Whenever possible, NEEA looks for existing organizations to host and maintain product specifications over time. 
 
In some cases, however, no such structure exists, or national specifications lag behind emerging technologies. In those situations, NEEA may develop a QPL to help establish clarity for the market. 
 
“So, our first question is always: is there already a structure in the market that can carry this forward?” Rehley said. “You look as far and wide within the existing market to find trusted organizations to host QPLs first.  They are usually closer to the manufacturers and customers, and they have an interest in maintaining and advancing the QPL on their own.”

Where Qualified Products Lists are Used 

QPLs are used across the energy efficiency ecosystem to support consistent decision making. Users include: 

• Utilities and program administrators, when designing incentive programs and establishing eligibility requirements 

• Engineers and building designers, when specifying equipment that meets energy-efficiency targets 

• Contractors and installers, when selecting products that align with program requirements 

• Manufacturers, when evaluating how their products compare to emerging market expectations 

By creating a shared reference point for product performance, QPLs help align programs and projects across the Northwest.

A Long-Term Investment in Market Transformation 

While QPLs may begin as a response to a specific market gap, they often become long-term investments. 
 
“If it’s something we take on, it’s a relationship,” Rehley said. “Even if you think it’s short-term, QPLs tend to take on a life of their own.” 
 
In some cases, QPLs influence national standards, incentive structures, or even policy, extending their impact beyond their original purpose. 
 
Ultimately, QPLs support NEEA’s mission to drive market transformation by translating technical analysis into practical tools the market can use. 
 
“They’re not about forcing the market,” Rehley said. “They’re about creating clarity, so when the market is ready to move, it can.”
