Naka Power Utilities (NWT) Ltd. 2026-28 General Rate Application

What You Need to Know

Naka Power Utilities (NWT) Ltd. (Naka) has submitted a General Rate Application (GRA) to the Northwest Territories Public Utilities Board (PUB) for 2026–2028.

A GRA is a regulatory process used to review electricity costs and determine whether changes to rates are required to ensure safe, reliable service.

Why Rates are Being Reviewed

On January 1, 2026, three utilities—Naka Utilities (NWT) Ltd., Naka Power Utilities (NWT) Ltd., and Naka Power Utilities (Yellowknife) Ltd.—were combined into one company: Naka Power Utilities (NWT) Ltd.

Following this amalgamation and changing operating conditions, Naka filed its GRA on April 30, 2026, to reflect updated costs for operating and maintaining the electricity system.

In its Application, Naka has requested approval of revenue requirements and corresponding rate increases by zone for the 2026, 2027 and 2028 Test Years relative to the 2025 Board-approved revenue requirements. The requested rate increases, as well as bill impacts effective July 1, 2026, before and after government subsidies are shown below in tables 1-3 and 4, respectively.

Interim Rates (2026)

Naka has also requested interim rate changes effective July 1, 2026, based on forecast costs for 2026. These rates are subject to review and may be adjusted following the hearing.
 

What’s Driving the Changes

The main factors vary by region:

  • Snare Zone: Costs are partly attributable to higher purchased power costs and the costs required to operate and maintain infrastructure. 
  • Taltson Zone: Investments in infrastructure, operation and maintenance costs and purchased power. 
  • Thermal Zone: Increases are mainly due to higher income tax, return and depreciation costs associated with capital.
