How could the accelerating geothermal projects in the Western US affect Southwest Gas?
Geothermal's lower cost may challenge Southwest Gas's resource planning The accelerating geothermal projects have reached a pricing milestone, with average costs reported at $105.56 per megawatt-hour in NV Energy’s 2026 resource plan. This pricing allows geothermal to undercut competing solar-plus-storage proposals by roughly 7%. Because geothermal provides firm, baseload generation, this new economic and reliability profile makes it a compelling resource for long-term planning. As an investor-owned utility, Southwest Gas must consider this shift in resource viability when planning its own energy portfolio and competitive offerings.

How it reaches Southwest Gas
-
NV Energy's 2026 resource plan indicates that geothermal power now averages $105.56 per megawatt-hour. This pricing milestone undercuts competing solar-plus-storage proposals by approximately 7%. This shift is supported by federal tax credits and technological advances.
The full event1independent outlet -
Geothermal power has reached a pricing milestone, with average costs of $105.56 per megawatt-hour in NV Energy’s 2026 resource plan. This pricing allows geothermal to undercut competing solar-plus-storage proposals by roughly 7%. This economic advantage, combined with its ability to deliver firm, baseload generation, makes it a stronger resource option for grid operators and utilities.

Why it matters
For Southwest Gas, which operates as an investor-owned utility in the energy sector, the increasing viability of geothermal represents a structural challenge to its competitive position. As geothermal becomes a more economically attractive and reliable resource for grid planners, it introduces a powerful alternative that could influence market dynamics and long-term demand for traditional utility services.
This trend is part of a broader shift in energy planning driven by technological advances and federal tax incentives. Data centers, for example, have emerged as a major driver of renewed interest in geothermal due to their need for constant and dependable power supplies. This push for reliable, around-the-clock clean power is accelerating the development of geothermal capacity across the western United States.
