SiEnergy, a subsidiary of Northwest Natural Holding (NWN), reached a settlement with key parties including Railroad Commission of Texas staff and local cities in its Texas general rate case, filed on September 22, the company stated on Wednesday.
Pending formal approval, the agreement resolves all case items by granting an $8.6 million increase in annual revenue, falling below SiEnergy's initial $12.0 million request, according to the statement.
The settlement establishes a $343 million rate base, a 9.8% return on equity, and an 8.0% overall cost of capital, while consolidating SiEnergy's gas distribution entities, Northwest said.
If approved by the RRC, the new rates are expected to take effect in November 2026. Additionally, the agreement sets up the framework for future participation in the Grid Reliability Infrastructure Program to support ongoing system investments, it added.
