NIGP 92580: Rate Engineering

NIGP 92580 Rate Engineering, an Item code, encompasses financial and analytical services state and local governments procure to validate, design, and justify utility rates—water, wastewater, solid waste, and related cost-of-service assessments that support rate-setting and capital planning decisions. Recent solicitations show municipalities and special-purpose districts using this code to commission comprehensive rate studies, cost-of-service analyses, and rate justification assessments that inform long-term financial planning and regulatory compliance, particularly under Proposition 218 and similar rate-adequacy frameworks.

State and local issuing bodies pursuing services under this code span city utilities departments (Arlington, Texas; Ventura County, California), county water and wastewater authorities (Madison County, Georgia), and state housing finance commissions (Washington State Housing Finance Commission). The City of Arlington issued two separate RFPs in 2026—one for a comprehensive water and wastewater rate study (due August 20, 2026) and another for solid waste rate justification assessment services (due May 28, 2026)—indicating repeat engagement by major municipal utilities on multi-year financial planning cycles. Ventura County Public Works Agency requested qualifications for a water rate study covering four waterworks districts (due May 21, 2026), requiring validation of rate structure models and development of recommended rates for fiscal years 2026–2031 under Proposition 218 requirements. The Washington State Housing Finance Commission solicited utility allowance analysis services for Low Income Housing Tax Credit properties statewide (RFP due May 29, 2026), with an annual budget ceiling of $15,000 and a two-year initial contract term. Geographic activity concentrates in California, Texas, Georgia, and Washington, with Texas and California showing the most recent municipal procurement activity. Responding firms typically must demonstrate specialized expertise in utility rate modeling, cost-of-service methodology, and regulatory compliance; competitive awards favor consultants with 10–20+ years of regional rate-setting experience and familiarity with state-specific utility governance frameworks.
