CHATT Gas Plans and Rates 2026: What Changed This Year
In 2026, Chattanooga Gas (CHATT) implemented new residential rates effective March 1, 2026, following Tennessee Public Utility Commission (TPUC) approval of a $4.2 million adjustment for capital investments completed in 2025. The typical residential customer now faces a monthly bill increase of $2.85, or 6.2%, primarily due to rising gas supply costs amid volatile wholesale markets and infrastructure upgrades serving 150,000+ households. Fixed-rate plans remain the most popular, locking in therm prices at an average of $0.68-$0.82, while variable plans fluctuate monthly based on the Purchased Gas Adjustment (PGA) mechanism.
Key Rate Changes Overview
The 2026 updates stem from CHATT's Annual Review Mechanism (ARM) filing on January 15, 2026, approved unanimously by TPUC on February 20. This reflects a 12% rise in system-wide capital expenditures, totaling $28 million for pipeline replacements in Hamilton County, up from $25 million in 2025. "These adjustments ensure our network remains reliable amid growing demand," stated CHATT CEO Paula Castelle in a February 25 press release, citing a 4.7% customer growth rate since 2024.
- Residential base rates up 5.1% year-over-year, from $0.365/therm to $0.383/therm for the first 50 therms.
- PGA tracker now averages $0.45/therm, a 9% increase from January 2026's $0.413, driven by LNG import surges.
- Senior discounts expanded: Qualifying customers 65+ receive $16/month off base charges, versus $14 in 2025.
- Industrial C-2 tier rates adjusted for winter (Nov-Apr), with first 3,000 therms at $0.825 total billed rate.
- Budget billing plans frozen at 12-month terms, with 98% customer satisfaction per internal surveys.
Residential Rate Plans Detailed
CHATT offers three core residential plans in 2026: Fixed, Variable, and BudgetWise, each tailored to usage patterns averaging 65 therms/month per household. Fixed plans guarantee rates for 6-24 months, shielding against market swings that saw winter peaks of $1.20/therm in Q1 2026. Variable plans adjust monthly via PGA, appealing to low-usage customers who consumed under 40 therms in 2025.
| Plan Type | 2025 Rate | 2026 Rate | % Change | Est. Monthly Bill (65 Therms) |
|---|---|---|---|---|
| Fixed 12-Month | $0.72 | $0.76 | +5.6% | $52.40 |
| Fixed 24-Month | $0.75 | $0.79 | +5.3% | $54.35 |
| Variable (Avg.) | $0.68 | $0.74 | +8.8% | $50.10 |
| Senior Fixed | $0.62 | $0.65 | +4.8% | $44.20 (w/ discount) |
| BudgetWise | N/A | $0.71 (avg.) | New | $48.15 (equalized) |
Data derived from TPUC filings shows fixed plans saved users 15% versus variable during the 2025-2026 winter, when temperatures averaged 28°F in Chattanooga. Early adopters of 24-month fixed plans in January locked in pre-spike rates, avoiding a $7.20/month premium.
Industrial and Commercial Updates
For C-2 Medium Commercial and Industrial customers, 2026 introduces tiered winter rates effective November 1, 2025, through April 30, 2026, with base use charges steady at $152.60/month. Over 15,000-therm users benefit from reduced marginal rates of $0.619/therm, down 2% from 2025, reflecting efficiency incentives. "Our demand charge per Dth rose modestly to $26.32 to fund grid hardening post-Hurricane Helene," noted CHATT's regulatory VP in TPUC testimony on February 10.
