STATEMENT OF WORK

Installation of Generac 50 kW Outdoor Backup Generator with Transfer Switch and

Accessories

1. BACKGROUND

The Institute for Telecommunication Sciences (ITS) provides research and development support for the National Telecommunications and Information Administration (NTIA) by performing basic research in radio science that provides the technical foundation for NTIA’s policy development and spectrum management activities, as well as solving telecommunications challenges for other Federal agencies, state and local Governments, private corporations and associations, and international organizations. Additionally, ITS addresses emerging telecommunications, information technology, and security challenges and contributes to the creation of telecommunications standards that support the full and fair competitiveness of the U.S.

communications and information technology business sectors.

2. OBJECTIVE

ITS requires the purchase and installation of brand or equal Generac SG050NA 50 kW Stationary Outdoor Backup Generator powered by a 4.5L inline 4-cylinder engine with LP vapor fuel system. The installation includes all necessary electrical, mechanical, and safety components required for full compliance with applicable codes and best practices. The system is designed to provide backup power for critical loads in the event of utility failure, meeting NFPA 99 and 110 standards and maintaining operational continuity. A backup generator be installed with a transfer switch at building I10C Table Mountain Advanced Communications Test Site. This building serves as a laboratory supporting a variety of telecommunications research projects.
