Applications Open for NAESCO Accreditation, Spring 2024

NAESCO is currently accepting applications from member companies interested in earning accreditation as an Energy Service Company (ESCO), Energy Service Provider (ESP), and Energy Efficiency Contractor (EEC).

The National Association of Energy Service Companies (NAESCO), the premier advocacy and accreditation organization for energy service companies (ESCOs), announces the opening of the Spring application round for its reputable accreditation program.

As part of its commitment to promoting excellence in the energy service company industry, NAESCO is currently accepting applications for accreditation through its twice-annual application process, providing industry players with an opportunity to earn recognition for their commitment to high-quality delivery, technical expertise, and standards.

What is NAESCO-Accreditation?

NAESCO's accreditation program is voluntary for members. It serves as a comprehensive tool that evaluates the work, standards, and reputation of companies dedicated to modernizing the built environment through energy efficiency and other energy-related optimization. The NAESCO-Accreditation program includes organizations that have demonstrated top-tier professionalism, technical implementation, ethical standards, and more.

What are the Requirements? 

The accreditation program opens twice a year, once in the Spring and again in the Fall, with NAESCO membership being a prerequisite to applying. Accreditation categories include Energy Service Company (ESCO), Energy Service Provider (ESP), and Energy Efficiency Contractor (EEC). The initial accreditation is valid for two years, with the option for renewal. Upon renewal, the accreditation extends to three years.

Each accreditation category involves a comprehensive evaluation of technical competencies and managerial skills, examining various aspects such as performance-based project approach, project engineering and design, financing, project management, operations, maintenance capabilities, and the ability to monitor and verify building energy cost savings.

Why Participate?

Participating in NAESCO's accreditation process brings numerous benefits and adds substantial value to companies who are awarded with the recognition:

- Companies hiring teams for their buildings' energy infrastructure needs trust NAESCO-accredited companies as the most reliable in the field.

- Accredited companies gain a reputable standing in the industry, positioning themselves as preferred partners for building infrastructure and energy efficiency projects.

- NAESCO-accredited companies play a pivotal role in revitalizing and optimizing existing buildings, contributing to a more sustainable future and managing the country's energy economy.

- NAESCO publishes a list of all accredited companies for public reference, enhancing visibility within the industry.

Taking the Next Steps 

For the Spring application process, companies seeking first-time accreditation or undergoing re-accreditation will pay a $6,700 fee (payment of fee doesn't guarantee accreditation, instead it covers program costs including data reference, reference checking, and independent reviewers). Following the application, each company undergoes a rigorous review by an independent and impartial committee of industry experts, evaluating the applicants' fundamental offerings and business processes. All information provided will be treated with confidentiality and solely utilized for the purpose of assessing the company's eligibility for accreditation.

The application process is now open, and completed applications are due on Friday, March 22, 2024. Companies that earn accreditation will be announced in June 2024.
