The Department of Defense, through the Portsmouth Naval Shipyard, is soliciting proposals for the rental of three (3) Diesel-Powered mobile tier 4 generators with built-in fuel tanks to support maintenance and repair operations for a Virginia class submarine at Groton Naval Base in Connecticut. The generators must comply with specific performance specifications, including emissions standards and load testing, and may include an automatic internal load bank or an external self-contained load bank. This procurement is critical for ensuring operational efficiency and regulatory compliance during the maintenance period, which spans from August 2025 to August 2026, with various testing and option periods outlined for each generator. Interested contractors should contact Christie Ashcraft at christie.j.ashcraft.civ@us.navy.mil or Alyssa Cress at alyssa.a.cress.civ@us.navy.mil for further details and to ensure compliance with the Navy's small business initiatives.
