Which of the following is NOT one of BHEL's facilities?

BHEL, or Bharat Heavy Electricals Limited, is a leading public sector enterprise in India known for its contributions to the manufacturing of electrical equipment and engineering services. The company has a variety of facilities designed to support its extensive operations, including manufacturing plants, service centers, and regional marketing centers.

The inclusion of training institutes as one of its facilities is not accurate. BHEL focuses primarily on engineering, manufacturing, and marketing but does not necessarily operate its own accredited training institutes in the same vein as its production and service infrastructures. The other facilities play a crucial role in BHEL's overall mission, such as ensuring efficient production, after-sales support, and marketing outreach within the industry.

In contrast, manufacturing facilities are critical for the production of various electrical and industrial equipment, service centers provide maintenance and support to customers, and regional marketing centers facilitate expanding BHEL’s market presence and managing client relationships. Therefore, while training and development are important, they do not represent a direct facility for the company's operational focus.
