About the eCatalog

Table of Contents



The Packaged Combined Heat and Power Catalog (eCatalog) is a voluntary public/private partnership designed to increase deployment of CHP in commercial, institutional and multi-family buildings and manufacturing plants. The core of the eCatalog are CHP Packagers who commit to provide pre-engineered and tested Packaged CHP systems that meet or exceed DOE performance requirements and CHP Solution Providers who commit to provide responsible installation, commissioning, maintenance and service of recognized Packaged CHP systems and also provide a single point of responsibility.

The eCatalog is an open source, web-based system that hosts US DOE recognized packaged CHP systems that will include select features designed to reduce economic and performance risk for the CHP user. The eCatalog is focusing on packaged CHP systems less than 10 MW in individual prime-mover capacity

Public sector Customer Engagement Partners (including state and local jurisdictions and utilities) interact with the eCatalog by linking their respective CHP outreach programs, support resources, and incentive programs to the eCatalog for Packaged CHP Systems.

The eCatalog will be routinely updated to add additional Packages, Packagers, Solution Providers and Customer Engagement Partners and/or for existing eCatalog stakeholders to update their offerings.


Rigorous Recognition Process

The Packaged Combined Heat and Power Catalog (eCatalog) is a voluntary public/private partnership designed to increase deployment of CHP in commercial, institutional and multi-family buildings and manufacturing plants. The core of the eCatalog are CHP Packagers who commit to provide pre-engineered and tested Packaged CHP systems that meet or exceed DOE performance requirements and CHP Solution Providers who commit to provide responsible installation, commissioning, maintenance and service of recognized Packaged CHP systems and also provide a single point of responsibility.

The eCatalog is designed to decrease installation barriers, lower risk, and reduce project costs and installation times by:

  1. Improving the market penetration of CHP in high technical potential markets that have not yet been cost-effectively developed due to lack of understanding of technology;
  2. Reducing perceived risk of installing and operating on-site generation by offering comparable standardization of CHP systems and in the field service agreements;
  3. Creating replicable CHP systems to reduce design errors and limit uncertainty with the associated performance, time, and cost impacts;
  4. Establishing standard and pre-qualified CHP technology systems and vendors to install them, leading to shorter decision times and lower hurdle rates, including at the property inspection phases such as occupancy inspections;
  5. Reducing customer acquisition costs for CHP vendors, which can be passed on to the consumer; and
  6. Expanding CHP product offerings, improving quality, and controlling costs by promoting increased competition.

Packager Recognition

The purpose of the U.S. DOE review and recognition process is to assure eCatalog users that packagers have proven engineering, design, assembly, and testing experience and capabilities to deliver Packaged CHP systems that install easily, can be commissioned as expected and deliver stated performance.

Be sure to provide enough information in your Packager Enrollment submission to demonstrate your CHP capabilities (i.e., facilities, design, assembly and service capabilities; CHP expertise – people; CHP experience – systems operating; CHP market focus and unique offerings – e.g. financing, remote monitoring) in the public facing 1,000-character, Company Information box. The purpose of the Additional Company Information is to provide the DOE reviewers with a better idea of your company’s CHP focus and capabilities.

Packaged CHP System Recognition

The U.S. DOE review and recognition process for Packaged CHP Systems is designed to verify that the system design and performance meets DOE requirements. The information requested for the public facing website is to provide the eCatalog user with enough performance data and physical information to instill confidence in the Packaged CHP System offering.

Each requested item was necessary to either convey to the eCatalog user the nature of the Packaged CHP system of provide the DOE reviewer with enough information to verify completeness of the system, operability of the system and verify performance data.

It is DOE’s expectation that these data requests will not present an undue burden on any Packager. While it is necessary to upload each item before a submission can be completed, please provide the best available information you have to complete each submission. It will be up to the reviewer and you to reach an understanding of the material, which can best begin after a submission is initially completed.


The End User, or their representative (e.g. consulting engineer of project developer) experience will allow anyone with a specific site requirement (zip code based) to quickly find the CHP packages that best fit the site requirements selected by the User. The key is reducing risk for end-Users, CHP Packagers and CHP Solution Providers by pre-engineering CHP packages and improving project delivery, operations and maintenance.

The eCatalog allows comparison of packaged CHP systems using standardized performance parameters:

  1. Three ambient temperatures are used for performance data (0. 59 and 95 degrees °F)
  2. Three performance points (100%, 75% and 50% prime mover capacity)
  3. Steam performance is measured at 15 and 125 psig saturated steam supply to site
  4. Hot water performance is measured at 180 °F hot water supply to site
  5. Chilled water performance is measured at Performance at 44 °F supply / 54 °F return temperatures; 95 °F dry bulb / 78 °F wet bulb ambient temperatures
  6. Sound Power is measured @ 1 m height and 10 m distance free field

You will need to use your specific site requirements to determine the actual of these systems to meet your specific needs. Keep in mind that the packages published in the eCatalog are for specific physical configurations and you site may require different configuration which may impact performance. End-Users and Consulting Engineers can engage with the eCatalog using the following four steps:

REGISTRATION – Registration is an important first step because it allows you to save search criteria and results. Registration is simple and access is found in the upper right corner of the Home page.

  • Favorite packages are only saved with named Saved Searches to allow easy retrieval by site name, application or other criteria.
  • If a search is not named, when the user clicks on the favorite star they will be prompted to name the search.
  • Users can also now select an existing Saved Search and overwrite the previously associated search facets with the current search facets.
    • Packages already associated with that Saved Search with still be connected, while their relevance will be updated for the new facets
    • This way users can update Saved Search parameters relatively easily without having to save a new search and add favorites again
  • On the "Favorites & Saves" page, the Saved Searches and associated packages are now all in expandable sections like the dashboards
    • The Associated Packages now appear here with the same search related relevance and highlighted facets just like they do on the search page
  • Deleting a Saved Search will also delete all associated favorite packages

Contact Registration

The primary contact for the packager must initially register as an individual user and then initiate the CHP Packager Enrollment Process (see next section).

Multiple, or associated, users can be connected to each Packager. To add additional associated users:

  1. The additional user needs to register as an individual account in the CHP eCatalog
  2. The primary contact sends an email with additional user's email address requesting the association of this new user, including the new user’s registered email address, to: chp.eCatalog@industrialenergytools.com
**See live example here: https://fake.ecatalog.industrialenergytools.com/loginAs/70

A box has been added to the upper right of the Packager dashboard that indicates how many "associated users" are currently connected to each Packager.

Example:

Clicking on this box will bring up a list of the users with contact info and instructions on how to add additional associated users:

CHP Packager Enrollment Process

The Packager contact information (above) will be automatically loaded when the Primary Contact initiates the Packager Enrollment Process. The Packager Enrollment Form currently includes three types of Packagers depending on how packaged CHP systems are distributed. It is important to initially select the proper Packager type as it will be locked, depending on your selection, after you submit your first Packaged CHP System application. The OEM Packager category is a direct response to national packagers with local distributors asking to be able to secure national recognition for packages that would only appear in the eCatalog listed under their respective distributors. The Regional Packager category as a direct response to Packagers that want to be able to collaborate and develop regional Packaged CHP systems to be shared with other packagers and receive recognition for these packages that would only appear in the eCatalog listed under their respective collaborative Packager names. Packager types include:

  • Packager (standard) – can submit packages for recognition and the packages appear publicly in the eCatalog directly from you and from any designated Solution Providers
  • OEM Packager - national OEM Packagers can upload packages for recognition. These packages do not appear publicly in the eCatalog through the OEM Packager, but only through the OEM's local distributors (eCatalog Packagers) that are designated to access and carry these recognized packages as their own
  • Regional Packager – can submit packages for recognition that will appear in the eCatalog directly from the Regional Packager, and optionally you can also allow other Packagers to directly distribute any or all or your packages. As in the case of the standard Packager, you can also distribute packages directly through designated Solution Providers.

Note: You can move from a Packager to an OEM Packager or a Regional Packager at a later date, but you cannot change from an OEM Packager or a Regional Packager once selected as this will potentially break established distribution links.



Company Description and Authorized Sales Territory

The company description will appear prominently on the detailed date sheet for every Packaged System you offer to the public. You have 1,000 characters to describe your company and its packaging expertise. Please include: CHP capabilities – facilities, design, assembly and service; CHP expertise – people; CHP experience – systems operating; CHP market focus and unique offerings – e.g. financing, remote monitoring.

Additional Company Information and Logo Upload

The purpose of the additional Company information is to provide the internal DOE reviewers with a more complete description of your company’s CHP focus and capabilities.


Uploading a Packaged CHP System Application

The Packaged CHP systems upload process begins at the CHP Packager Dashboard. Under the SUBMITTED CHP PACKAGES banner is the SUBMIT NEW CHP PACKAGE button.

This opens up the Enter New CHP Package screen. To begin the process, you need to enter some basic system information.

Basic System Information

First enter the specific model number of the package you are submitting. Note that each key searchable system parameter combination (e.g., prime mover, number of prime movers, thermal output type, etc.) requires a different model number. Please plan for this with regard to model numbering.

Similar packages with only one or two different parameters must be entered as separate packages. Key searchable system parameters include:

  • Prime mover type – currently combustion turbine, reciprocating engine, microturbine and fuel cell
  • Thermal output – a hot water only Packaged CHP System is different from a steam and hot water Packaged CHP System. You can certainly have a system that produces hot water, steam and even chilled water, but this system must include all heat exchangers and major thermal components such as the chiller.
  • Fuel type – natural gas, propane, land fill gas and digester gas
  • Interconnection type – grid parallel only; grid island capable, black start manual transfer; and grid island capable, black start auto transfer

Note: When uploading similar packages in most cases, much of the data is already collected and may even be available from another system upload (data upload spreadsheets can be downloaded from submitted packages). For example, if you have a system uploaded on natural gas and you are adding a digester gas version, you would just need to update the performance spreadsheet reflecting the new gas composition and the addition of a fuel treatment skid to clean up the gas. All the other requested material should be the same except for these changes.

Package Availability

If you established your company as a Packager, then your packages are automatically available to the Public. The only additional question on availability is if the Packaged CHP System being uploaded would be available to Solution Providers that you would approve on a packaged system by packaged system basis.

If you established your company as an OEM Packager, then your packages are available to your designated Packagers (OEM distributors) in the eCatalog. The eCatalog assumes that OEM Packager’s Packaged CHP Systems are available to Packagers that are approved by the OEM Packager, and that OEM Packages are not available to the Public or Solution Providers. There are no specific availability questions on the form for OEM Packagers.

If you established your company as a Regional Packager, then your packages can be available to the public, other designated Packagers (distributors) and/or designated Solution Providers in the eCatalog. Regional Packagers should select appropriate package availability as listed below.



Packaged CHP System Specifications and Background Materials



Packaged CHP System Specifications

The first data to be uploaded is the public facing performance and system information for the eCatalog user (end users, consulting engineers, ESCOS, Developers, etc.), the Customer Engagement Partners (states, municipalities and utilities), and the internal DOE reviewers.

The performance data is submitted through a downloadable Excel spreadsheet. This allows you to work independently from the eCatalog, and cut, copy, paste and duplicate data as needed to save time. When the spreadsheet is complete, it can be easily uploaded to complete this part of the submission.

Once the Excel data is uploaded, you must hit FINISHED to save the data.

If data is missing, a red bar will appear at the top of the page and the missing data will be highlighted in the detailed specification table below. You have the option to clear the data in the form, fix/add the data to the spreadsheet and re-upload it, or add the data online where indicated.

When data is completed and successfully uploaded, the status will change to “completed”. You have the ability to go back and modify the data at any time by pressing the SPECIFICATION FORM button.

Packaged CHP System Simplified Schematic

The next public facing item to submit is the Packaged CHP System Simplified Schematic:



This schematic shows the DOE reviewer, User (End-User, Consulting Engineer, ESCO) and Customer Engagement Partner the basic components of the Packaged CHP System. This 2G schematic from the NYSERDA catalog is a good example. You need to be able to track fuel flow, electricity flow, and thermal flows through the CHP system. All major components must be identified by make and model number (including alternates). If you are providing switchgear and protective relays, they should be shown as well. Note that the performance temperatures and pressures for the eCatalog performance parameters must also be indicated.

The eCatalog’s focus is centered on private sector Solution Providers. A Solution Provider is responsible for installation, commissioning, maintenance and service of recognized Packaged CHP systems and providing a single point of responsibility. CHP Solution Providers are expected to demonstrate the ability to fully support recognized Packaged CHP systems nationwide or in specific areas of the country. A Solution Provider may be an original equipment manufacturer, a system integrator, or any other entity that has the rights to install Recognized Systems1 in at least one Qualified Service Territory2. A Solution Provider must provide a single point of responsibility for site integration, installation, all maintenance and service activities (planned and unplanned) related to Recognized System for a period of not less than five (5) years from the date of electric grid interconnection recognition. The Vendor partner may use subcontracted teams to fulfill these obligations. Regardless of the teaming arrangement, however, the Solution Provider remains fully responsible for all aspects. Solution Provider must have demonstrated experience designing, installing and maintaining CHP equipment.

1Recognized Packaged CHP Systems that are pre-engineered, pre-tested products that meet the specifications and requirements in this Guide and have demonstrated performance as an integrated system based on one of the three ASERTTI CHP Testing Protocols or equivalent.

2 A Qualified Service Territory is a city, state, geographic region or utility service territory where a Vendor partner offers a single point of responsibility for Packaged CHP System installation, commissioning and a Bumper-to-Bumper Assurance Plan including all system components


An essential element in market uptake of energy efficient technologies, like CHP, is a robust customer engagement partner. The eCatalog provides a unique platform for convening recognized equipment and services with state, local and utility market outreach, customer acquisition and incentive programs. Offered. States, localities and utilities that are implementing programs and policies to increase the use of CHP in support of key economic, security, efficiency and environmental goals can select the packages offered by Solution Providers or Packagers in their region to indicate that these packages qualify.


Manufacturing and industry interests in the US have historically supported the advancement of CHP as it helps maintain their economic competitiveness by lowering their day-to-day cost of operation and reducing their exposure to process disruptions caused by grid outages. The thermal energy recovered from generating power on-site with a CHP system can be used to provide process heating, space heating and cooling, and refrigeration depending on the needs of the particular installation. The US DOE supports a robust CHP program as a means to revitalize and grow Americas industrial base by improving energy infrastructure.

  • Efficiency & Reliability. Flexible CHP technologies offer strategies to meet user energy needs cost-effectively, efficiently and safely. For example, CHP systems simultaneously produce double or triple energy from a single source at overall efficiencies of up to 80% energy efficiency compared to about 50% for conventional separate heat and power. CHP reduces fuel usage and greenhouse gas emissions (by about one-third) and increases grid safety and stability in support of solar and wind options. CHP systems provide localized, autonomous, often modular systems that eliminate transmission line power loss and enable the collection and storage of energy from many sources, providing greater security against outages, stronger grid resilience, and lower environmental impacts.
  • Increased Profitability. Reducing fuel usage, lowering the cost of clean operations, and making project approvals easier to obtain all contribute to the bottom line. CHP system operation has historically proven to provide reliable operation through electric grid outages, providing vital services and production continuation.
  • Energy Independence. By efficiently using domestically produced natural gas and emerging domestic renewable fuels such as landfill and digester gas, CHP systems help reduce America’s dependence on foreign fuel.
  • Cleaner Air. CHP’s high efficiency and reliance on clean fuels lowers emissions of both criteria pollutants and greenhouse gases.
