Tariff Regulation and Affordability Training Course

Participants can measure customer affordability using appropriate household, billing and service data.

• Define affordability using expenditure shares, residual income and service levels
• Select household survey variables for bills, income, assets and consumption
• Construct consumption deciles and customer segments from billing and survey data
• Compare median-bill, income-ratio and residual-income affordability indicators
• Separate ability-to-pay analysis from stated willingness-to-pay survey evidence
• Test data limitations, informal incomes and unserved household bias

Participants can develop and assess a revenue requirement for a regulated service provider.

• Build revenue requirements from efficient operating costs, depreciation and tax
• Calculate regulated asset base additions, disposals and depreciation schedules
• Estimate weighted average cost of capital using debt and equity inputs
• Assess prudency reviews, efficiency benchmarks and allowed-cost adjustments
• Reconcile forecast demand, losses, collections and required annual revenue
• Document cost allocation between customer classes and regulated services

Participants can design tariff structures that recover approved costs while testing distributional effects.

• Design fixed, volumetric, block and time-of-use tariff structures
• Model increasing-block tariffs against household size and consumption patterns
• Set connection charges, minimum bills and seasonal tariff provisions
• Test cross-subsidies using cost-to-serve and bill-impact analysis
• Compare uniform, differentiated and lifeline tariff options against policy objectives
• Translate approved revenue requirements into published tariff schedules

Participants can assess subsidy and customer protection mechanisms for affordability, targeting and fiscal control.

• Distinguish universal price subsidies from targeted household support mechanisms
• Assess targeting errors: exclusion, inclusion, administrative cost and stigma
• Design lifeline blocks, social tariffs and means-tested bill assistance
• Coordinate utility subsidies with cash transfers and social registries
• Estimate fiscal exposure under alternative subsidy eligibility and uptake assumptions
• Protect service continuity while managing arrears, disconnection and reconnection rules

Participants can compare economic regulatory models and their consequences for tariff trajectories.

• Apply RPI-X price-cap regulation to multi-year tariff paths
• Compare rate-of-return, revenue-cap and yardstick competition approaches
• Set efficiency factors from productivity evidence, benchmarking and forecast uncertainty
• Specify quality-of-service incentives, output measures and penalty mechanisms
• Treat inflation, exchange-rate movements and pass-through costs transparently
• Review regulatory periods, reopening clauses and exceptional-event adjustments

Participants can prepare and assess tariff submissions through a fair, evidence-based regulatory process.

• Prepare tariff applications with auditable assumptions, schedules and supporting evidence
• Plan consultations for customers, civil society, municipalities and large users
• Evaluate stakeholder submissions using materiality, evidence quality and statutory tests
• Write reasoned decisions that explain trade-offs, evidence and determinations
• Manage confidentiality, data publication and procedural fairness requirements
• Create communications explaining bill changes, support and complaint channels

Participants can build and interpret tariff scenarios for regulatory and policy decisions.

• Build linked customer, consumption, cost and revenue forecast models
• Run tariff scenarios for inflation, demand shocks and collection changes
• Calculate bill impacts by decile, service level and customer class
• Stress-test affordability under drought, fuel-price and currency scenarios
• Use sensitivity tables to expose drivers of revenue and subsidy needs
• Present assumptions, outputs and limitations for regulatory decision-makers

Participants can design temporary affordability responses during economic, operational and humanitarian shocks.

• Diagnose arrears using ageing profiles, payment behavior and service interruptions
• Balance cost recovery with protections for vulnerable and crisis-affected households
• Design temporary relief measures with exit criteria and fiscal controls
• Assess tariff implications of emergency supply, rationing and asset damage
• Coordinate humanitarian actors, local authorities and utility customer-service teams
• Monitor gender, disability and displacement barriers to tariff support

Participants can plan tariff implementation and establish indicators for regulatory and affordability monitoring.

• Define tariff implementation milestones, ownership, dependencies and approval gates
• Specify billing-system changes, customer notices and frontline-staff procedures
• Track collection, consumption, complaints, disconnections and subsidy uptake indicators
• Establish review triggers for affordability deterioration and revenue shortfalls
• Create regulatory reporting packs for boards, ministries and public disclosure
• Draft a 90-day application plan for a live tariff issue
