Variances due to changes in natural gas prices and transportation volumes have little impact on revenues because, under our rate design methodology, the majority of overall cost of service is recovered through firm capacity reservation charges in NWP’s transportation rates.
Revenues increased primarily due to higher Natural gas transportation service revenues driven by rate increases and increased firm transportation revenues from new contracts.
Operating and maintenance expenses increased primarily due to higher contracted services related to integrity assessments.
Depreciation and amortization expenses increased primarily due to new assets placed in service.
Interest expense was primarily impacted by a 2025 term loan issuance and retirement.
Interest income increased primarily due to higher interest income on advances to Williams during 2026.
