Affordability is the Ceiling
Between the compliance floor and the bill ceiling, every capital dollar has to earn its place.
Utility bills have become a political issue. Utilities requested about $31 billion in rate increases in 2025, more than double 2024, and governors and commissions are now setting conditions on rate cases, cutting and denying requests.
Yet most capital plans are still built bottom-up and tested for bill impact last, if at all. Bill impact has to become a weighted constraint on every capital decision, priced alongside safety, reliability and cost, and defensible to commissions before the rate case is filed.
Six Months That Formed the Ceiling
Aging assets, rising costs, environmental pressures, and evolving regulations are making water infrastructure investment decisions increasingly complex.
Traditional spreadsheet-based capital planning can make it difficult to compare investment alternatives, understand trade-offs, and demonstrate why certain projects should be prioritised over others.
What You’ll Learn in This Whitepaper
Explore how utilities can make affordability a planning constraint to:
- Test plans against an explicit bill ceiling: Check every project’s bill impact against limits like New York’s 6% of household income target before filing.
- Rank for value, not for deferral: Prioritize investments by value per dollar of bill impact, so the plan already knows what to defer when a request is cut.
- Keep a fallback ready: Build a budget-constrained option alongside the preferred case, with the rationale for every project documented.
- Prove the case project by project: Trace each investment from justification to filing exhibit, and track forecast against actual spend and benefits.
- Respond when conditions change: Monitor bills, rulings and dockets, and re-optimize the portfolio when a governor or commission acts.

Questions for Utility Leadership Before the Next Rate Case
If the rate case fails on affordability, these are the questions that would have caught it early.
- What is the bill impact of each project in our plan, and how would we show the commission that ranking in one model?
- If we had to present a budget-constrained option tomorrow, which projects fall out, and who decided?
- Which projects could we defend in plain language with reliability data or a cost/benefit case, and which could we not?
- When a governor, legislator or commission signals on affordability, how many days pass before the portfolio is re-run?
