NIGP 92580: Rate Engineering

NIGP 92580 Rate Engineering, an Item code, encompasses utility rate studies, rate justification analyses, and financial feasibility consulting for water, wastewater, solid waste, and other municipal utility systems. State and local governments procure these services to develop defensible rate structures, conduct cost-of-service analyses, evaluate revenue adequacy, model alternative rate methodologies, and support rate ordinances and bond financings. The work typically combines financial analysis, actuarial modeling, stakeholder engagement, and compliance documentation tied to Proposition 218 requirements (in California), FAA grant assurances (in airport context), or federal utility regulations.

Issuing bodies span cities, counties, water districts, transit authorities, and special-purpose utility agencies across multiple states. Recent solicitations show activity from the City of Arlington (Texas), City of Tampa (Florida), City of Phoenix (Arizona), Ventura County Waterworks Districts (California), Washington State Housing Finance Commission, Madison County (Georgia), and the City of Tucson (Arizona). The City of Tampa and City of Phoenix have each issued multiple task-order-based rate and utility consulting RFPs, suggesting repeat procurement volume at larger municipal utilities. Rate work frequently follows federal or state funding triggers—FAA appropriations for airport projects, Appalachian Regional Commission grants, Community Development Block Grants, or Low Income Housing Tax Credit program compliance—and is often bundled with water demand forecasting, infrastructure planning, and capital facility fee reviews.

Recent opportunities reflect geographic concentration in the Southwest (Arizona, California) and Southeast (Florida, Georgia) with secondary activity in the Pacific Northwest (Washington State) and Texas. The City of Arlington's rate justification RFP (26-0233, due May 28, 2026) sought solid waste cost-of-service analysis. The City of Tampa's rate consultant RFP (25-P-00156, due May 23, 2025) targeted water, wastewater, and solid waste advisory services on a task-order basis with up to $1 million contract value over five years and WMBE/SLBE participation incentives. The Ventura County Waterworks Districts' water rate study RFQ (RFQ20260508, due May 20, 2026) required 20+ years of similar experience and Proposition 218 compliance expertise, with preliminary deliverables due September 2026. The City of Phoenix's water demand forecasting QVL procurement (RFQU260145, due March 20, 2026) sought prequalification of multiple firms across six service categories with five-year task-order contracts. The Washington State Housing Finance Commission's utility allowance analysis RFP (202604AMC, due May 29, 2026) addressed Low Income Housing Tax Credit methodology validation across multiple utility types, reflecting specialized technical scope and annual budget cap of $15,000.
