An energy service company (ESCO) is primarily defined as a business that offers energy savings solutions through efficiency measures. This definition encompasses a range of services, including energy audits, energy efficiency retrofits, and the implementation of projects that reduce energy consumption and costs for clients. ESCOs often take a performance-based approach, meaning they may guarantee energy savings and share in the savings with their clients.

The essence of an ESCO's business model is to provide comprehensive solutions that improve energy efficiency, often guaranteeing performance through measurement and verification processes. This can include not only the installation of energy-efficient equipment but also offering financing options and ongoing maintenance. By focusing on energy savings solutions, ESCOs help organizations reduce their energy bills while improving their overall energy management.

In contrast, companies that simply provide energy-efficient appliances or are contractors for renewable energy installations do not capture the broader scope of services that define an ESCO. Utilities that provide energy resources focus more on the delivery of energy rather than the implementation of efficiency solutions. Therefore, identifying the key role of an ESCO as one that balances energy efficiency solutions with performance guarantees clarifies why the correct choice highlights their comprehensive service offering.
