Battery for Continuous Count Traffic Sites

The Illinois Department of Transportation (IDOT) is seeking bids for high-performance lithium iron phosphate (LiFePo4) batteries to support continuous count traffic monitoring sites through Solicitation Number 25-494DOT-FINAD-B-48342. The procurement involves three specific battery configurations: 12V 52Ah, 12V 100Ah, and 12V 300Ah, all designed for Group 31 case compatibility and intended to power 130+ traffic monitoring stations. These batteries must meet rigorous technical specifications, including an IP67 waterproof rating, operational temperature range of -4 to 113 degrees, high-impact and flame-retardant casings, and a Battery Management System with over 3000 charge cycles. Electronic bids must be submitted through the BidBuy platform by August 26, 2025, with proposals remaining valid for 180 days after opening. Evaluation criteria will focus on bid responsiveness, vendor responsibility, and lowest overall total price, with strict requirements for electronic submission of all documentation including Vendor Disclosure and Offer to the State of Illinois forms.

The solicitation encourages participation from diverse vendors, including potential opportunities for veteran-owned and small businesses, though no specific set-aside percentages are mandated. The contract will have an initial twelve-month term with a maximum potential duration of ten years, and batteries will be delivered to the IDOT Traffic Equipment Repair Shop in Springfield, Illinois. While no specific budget range is explicitly stated, the procurement is critical for collecting traffic data required by the Federal Highway Administration's Highway Performance Monitoring System. Vendors must complete comprehensive vendor disclosure forms, certify compliance with state regulations, and demonstrate ability to provide newly manufactured equipment with standard manufacturer warranties. The state reserves the right to reject any or all bids and make award decisions in its best interest, with potential integration into existing traffic monitoring infrastructure across Illinois's continuous count traffic sites.
