Value Score™ Methodology
The Electricity Value Score™ is a composite metric that combines affordability, price position, and data freshness into a single 0–100 score.
Components
The raw score uses three inputs:
- Affordability index (60% weight) — Normalized 0–100 score where higher = more affordable. Derived from the state's rate relative to the national min/max range.
- Inverse price component (30% weight) — 100 minus the normalized position within the rate range. Lower rates contribute more.
- Freshness boost (0–5 points) — Added based on data recency: fresh +5, aging +2, stale +0.
Weighting
Raw score = 0.6 × affordability + 0.3 × inverse price + freshness boost. The result is normalized to a 0–100 scale for display.
Tier interpretation
- 80–100 — Excellent
- 60–79 — Strong
- 40–59 — Moderate
- 0–39 — Weak
Limitations
The Value Score is a relative ranking tool. It does not predict actual bill outcomes. Affordability and inverse price are derived from the same rate data, so they are correlated.
Data sources
All inputs come from our normalized state data. See sources and freshness scoring.
