Northwest Natural Holding Co Announces Texas Rate Case Settlement

What Happened
Northwest Natural Holding Company (filed 8-K on Sept. 23, 2026) announced a settlement in the Texas general rate case for its wholly owned indirect subsidiaries SiEnergy Gas, LLC; Pines Gas, Inc.; and Pines Gas Development, Inc. The parties filed a stipulation with the Railroad Commission of Texas on Sept. 22, 2026, that consolidates the three companies, establishes systemwide rates, and would set new rates expected to take effect in November 2026, subject to RRC approval.

Key Details

• Stipulation filed Sept. 22, 2026; press release dated Sept. 23, 2026.
• Agreed revenue requirement increase: approximately $8.6 million (original request was $12.0 million).
• Capital structure: 59.75% equity / 40.25% long-term debt.
• Return on equity: 9.8%; overall cost of capital: 8.0%.
• Combined rate base: about $343 million (a $177 million increase since the 2023 rate case).
• Stipulation sets baseline factors for Texas’ Gas Reliability Infrastructure Program (GRIP); SiEnergy must make an initial GRIP filing within two years to participate.

Why It Matters
The settlement, if approved by the Railroad Commission of Texas, would raise allowed revenues for NW Holdings’ Texas gas operations and establish consolidated, systemwide rates and a targeted cost of capital—factors that directly affect regulated utility earnings and cash flow. New rates are expected to begin in November 2026 but remain subject to the RRC’s review, possible modification, or denial. The company also notes forward-looking statements and related risks in the filing; investors should watch for the RRC order and any future regulatory prudence reviews or adjustments under the GRIP program.
