NAESCO Accreditation Programs

Accreditation Categories

NAESCO offers three categories of Accreditation for companies in the energy service business: Energy Service Company (ESCO), Energy Service Provider (ESP) and Energy Efficiency Contractor (EEC).

Energy Service Company (ESCO)

ESCOs develop and implement turnkey, comprehensive energy efficiency projects. ESCOs offer performance-based contracts (i.e., contracts that tie the compensation of the ESCO to the energy savings generated by the project) as a significant part of their business. To gain accreditation, ESCOs must demonstrate the technical and managerial competence to design and implement projects involving multiple technologies, including:

  • Lighting
  • Motors and Drives
  • HVAC Systems
  • Control Systems
  • Building Envelope Improvements

ESCOs must also demonstrate the ability to provide the full range of services required for a comprehensive energy efficiency project, including:

  • Energy Audits
  • Design Engineering
  • Providing or Arranging Project Financing
  • Construction Management
  • Commissioning
  • Operations and Maintenance of Energy Efficiency Technologies
  • Verifying Energy Savings

Energy Service Provider (ESP)

ESPs in most instances will offer all of the services offered by ESCOs (see above), and additionally offer energy supply options. These options can include:

  • Development and implementation of build/own/operate distributed generation, cogeneration or combined heat and power (CHP) projects;
  • Arrangement of firm contracting of energy supply.

Energy Efficiency Contractor (EEC)

EECs offer some, but not all, of the services of an ESCO (see above). EECs typically concentrate on one energy efficiency measure (e.g., lighting) or one type of service (e.g., engineering or project management), but can offer multiple measures or services. EECs typically work as subcontractors to ESCOs or ESPs.

NAESCO Accreditation

What NAESCO Accreditation is Not

There are certain things that accreditation does not mean. It does not mean that NAESCO certifies either expressly or by implication: that any accredited company's customer(s) will, in fact, realize cost savings by that company; or that any accredited company has any particular level of financial strength or viability.

Featured Accredited Member

Accredited by NAESCO in 2016, Navitas is a Kansas based independent provider of comprehensive energy services currently serving clients in the Midwest. 

Navitas provides the development, design, engineering, installation, savings verification and utility cost management of comprehensive projects that reduce energy, operations and maintenance costs of client facilities. These projects generally include a variety of measures customized for each facility designed to improve the efficiency of major building systems and equipment.

A notable recent success story is the North Kansas City School District located in a suburb of Kansas City, Missouri. The school district covers more than 82 square miles, serves more than 18,500 students through 30 school locations, which include 21 elementary schools, five middle schools, and four high schools, as well as 10 support facilities. Like many school districts, North Kansas City School District was faced with aging facilities, rising utility costs, and school funding reductions. Navitas implemented a comprehensive program that utilized an energy management plan, equipment and system replacements and data analytics to optimize building performance.  Over $30 million dollars of improvements have been funded from over 30% annual utility savings that is being achieved.
