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

Headquartered in Harrisburg, PA, McClure Company has been providing premier engineering, energy and construction services since 1953 and has been an accredited Energy Services Company by NAESCO since 2009.  The company is built upon core values that include developing legacy relationships, financial stability through strategic and diverse offerings and a caring for the communities they serve and people they employ.

"NAESCO accreditation often serves as a third party validation for our clients; it’s a very visible indication of our commitment and expertise in the energy services marketplace.  Additionally, we benefit on many levels from our affiliation with the community of energy services professionals." - Shayne Homan, PE, Director of Energy Services, McClure Company

Through a Private - Public - Partnership, the Greencastle Antrim School District has recently experienced the benefits of McClure’s core values.  Like many of their peers, the District was faced with aging facilities in need of upgrades.  A 3rd party feasibility study identified $50M in recommended upgrades but that far exceeded their financial abilities.  The District called upon their professional team to help identify a more targeted scope of work that not only upgraded their critical needs and garnered guaranteed results but also allowed them to phase in the work over a 5 year period.  As a result, McClure sculpted a $20M, 5 year plan with guaranteed costs and savings.  The final phase of the program will be substantially complete in September, 2017.
