Cascade Natural Gas Rates to Rise This October

Live Poll

Do you expect your household's monthly energy expenses to remain manageable after the upcoming rate increases?

Starting October 31, 2026, Cascade Natural Gas customers in Oregon will see their monthly bills rise by approximately 10.7%. The adjustment follows an order from the Oregon Public Utility Commission to cover costs for system maintenance, environmental compliance, and new infrastructure investments.

Why it matters

These rate hikes are necessary to fund critical system upgrades and environmental compliance requirements mandated by the state. While costs have risen for infrastructure, the Purchased Gas Adjustment component of the bill actually saw a decrease due to lower wholesale prices and reduced consumption during recent warm winters.

Typical residential customers using 57 therms will face a $7.38 monthly increase, representing a 10.7% rise. Additionally, the commission established a new $1,500 incentive program for heat pump installations.

The players

Oregon Public Utility Commission

This state regulatory body is responsible for overseeing utility rates and ensuring reliable service for residents across Oregon.

Cascade Natural Gas

This utility provider delivers natural gas services to customers throughout regions of Oregon.

The details

The finalized rate increase was determined through three partial stipulations between participating parties, combining outcomes from a general rate case and an annual Purchased Gas Adjustment. The commission also mandated a three-year phase-out of line extension allowances for new customers to align with updated cost recovery schedules for the Climate Protection Program.

Market Landscape

This regulatory decision aligns utility investment models with state environmental mandates, such as the Climate Protection Program. By passing infrastructure costs directly to consumers without corporate profit margins, the commission prioritizes grid maintenance and sustainability over shareholder returns.

Most residential customers will see their monthly energy expenses increase by $7.38 starting at the end of October. However, homeowners looking to offset these costs may qualify for a new $1,500 incentive for installing heat pump equipment.

The takeaway

Customers should review their monthly usage patterns to determine if taking advantage of the new heat pump installation incentive could lower their long-term energy costs. Additionally, future regulatory reviews regarding gas adjustment filings may eventually lead to partial refunds for ratepayers.
