HB0046 amends Wyoming’s Chapter 22 production-tax scheme (originally for wind) to include electricity generated from solar and from nuclear reactors, adjusts the chapter’s definitions and exemptions, and repeals a separate statutory chapter that previously governed taxation of nuclear-generated electricity. The bill sets the mechanics of taxation at the point of interconnection and keeps the existing reporting cadence.
The practical effect is a consolidation of production-tax treatment across three generation types and an explicit date (January 1, 2027) when solar and nuclear generation become subject to the Chapter 22 regime. For developers, utilities, and state revenue officials, the change replaces a separate statutory framework for nuclear generation with the wind-based model and extends an excise tax to solar projects that were previously outside Chapter 22.
At a Glance
What It Does
The bill expands the excise tax in Chapter 22 — previously applied to wind — to cover electricity produced from solar and nuclear generating facilities, revises the chapter’s definition of "generating facility," and repeals W.S. 39-23-101 through 39-23-111 (the former nuclear electricity tax chapter). It specifies taxation at each megawatt-hour at the point of interconnection.
Who It Affects
Large-scale solar project owners, operators of in-state nuclear reactors or nuclear generating facilities, utilities that interconnect and purchase electricity, and the Wyoming Department of Revenue (which will administer the unified chapter). Smaller distributed-generation behind-the-meter systems are affected only if they meet the chapter’s production and sale triggers.
Why It Matters
The bill broadens Wyoming’s production-tax base and standardizes administration for three distinct generation technologies, which affects project economics and state revenue forecasting. It also creates questions about transitional treatment, statutory consistency, and administrative implementation that tax and energy counsel will need to resolve before projects come online under the new regime.

What This Bill Actually Does
HB0046 rewrites Chapter 22 to treat electricity from solar arrays and nuclear reactors the same way the current chapter treats wind-generated electricity. It replaces the chapter’s definition of "generating facility" so that it explicitly covers facilities producing electricity from wind, solar, or a nuclear reactor inside Wyoming.
The bill then states that an excise tax is levied on production from those resources and that the tax is measured by megawatt-hours at the point where the facility interconnects to transmission.
The bill also modifies the chapter’s exemption language so that the three-year post‑commercial-operation safe harbor — previously described for wind turbines — is expressed in terms of the "generating facility," which brings solar and nuclear facilities into that timing rule. Reporting and collection procedures remain tied to the existing Chapter 22 framework: producers must report megawatt-hours by February 1 following the production year.Crucially, HB0046 repeals W.S. 39-23-101 through 39-23-111, the separate statutory provisions that formerly governed taxation of electricity produced from nuclear reactors, and it sets the effective and applicability date for solar and nuclear production on or after January 1, 2027.
The bill therefore consolidates nuclear taxation under Chapter 22 instead of the repealed chapter. However, the text contains drafting inconsistencies — some provisions still refer specifically to wind or to dates tied to earlier statutes — which will require clarification for administration and compliance.
The Five Things You Need to Know
Section 1 amends Chapter 22 to expand the production excise tax to electricity from wind, solar, and nuclear generating resources and changes the chapter title to reference wind, solar, and nuclear.
Section 2 repeals W.S. 39-23-101 through 39-23-111 — the separate chapter that previously governed taxation of electricity produced by nuclear reactors.
The bill measures the tax on a per-megawatt-hour basis at the point of interconnection with an electric transmission line and retains the current reporting deadline of February 1 for producers to report prior-year MWh.
The existing three-year exemption that delays taxation until three years after a generating facility first produced electricity for sale is carried forward in the amended exemption language, applying the timing rule to the defined "generating facility.", Sections 3 and 4 make the act and its application to solar and nuclear electricity effective January 1, 2027 (the statute repeatedly leaves wind treatment tied to earlier dates).
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Redefines 'generating facility' to include solar and nuclear
This amendment expands the statutory definition so that "generating facility" explicitly covers facilities producing electricity from wind or solar resources and any facility generating electricity from a nuclear reactor in Wyoming. Practically, that brings solar and nuclear projects within Chapter 22’s scope and triggers the chapter’s compliance obligations (reporting, tax measurement, and exemptions) for those facilities. For counsel, the key consequence is that projects previously outside Chapter 22 will now need to be evaluated under its terms.
Imposes the excise tax on wind, solar and nuclear production
The imposition clause is revised to levy an excise tax on electricity produced from wind, solar and nuclear generating resources, assessed per megawatt-hour at the point of interconnection. While the bill states the tax applies to electricity produced for sale or trade, it leaves existing legacy language tying wind production to a 2012 start date, creating potential ambiguity about effective dates for different resource types. The statute does not restate any tax rate or exemptions from other codes, so administrators will map this clause to existing rate language in Chapter 22 or related sections.
Extends the three-year post‑commercial exemption to the 'generating facility'
The exemption subsection carries forward the three-year delay before a generating facility becomes taxable after it first produces electricity for sale, but replaces resource-specific wording with the chapter-wide term "generating facility." That change appears intended to extend the same start-up relief to solar and nuclear projects, but the text’s slight garbling and lack of resource-specific transition rules could leave disputes over when a given facility’s three-year clock starts, especially for phased projects or repowered facilities.
Reporting and compliance remain under the Chapter 22 schedule
The bill keeps the existing reporting requirement that producers report their in-state megawatt-hours on or before February 1 following the production year. Although the subsection as amended still references wind in its wording, the legislative intent — and the chapter’s redefinition — is to make the reporting duty apply to solar and nuclear producers as well. Practically, that means DOR and producers will need to update forms and filing guidance to reflect the broader production base.
Repeal of separate nuclear chapter and effective/application dates
Section 2 repeals W.S. 39-23-101 through 39-23-111 (the former nuclear electricity tax chapter). Sections 3 and 4 set the bill’s application and effective date to January 1, 2027 for electricity generated from solar resources or nuclear generating facilities. This creates a clear future start date for solar and nuclear under Chapter 22 while leaving wind on its historical timeline; practitioners must reconcile the repeal with any continuing obligations or credits that were governed by the repealed chapter.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Wyoming Department of Revenue — gains a consolidated statutory framework that can simplify administration and enforcement by housing wind, solar, and nuclear production taxation in a single chapter rather than split across different statutes.
- State treasury and budget planners — broadened taxable base helps forecast and potentially increase production-related revenue streams once solar and nuclear generation begin under Chapter 22 effective 1/1/2027.
- Tax compliance teams at vertically integrated utilities or independent power producers — benefit from a single set of reporting rules (per-MWh at interconnection and a uniform reporting calendar) rather than navigating divergent statutory regimes for different generation types.
Who Bears the Cost
- Owners and operators of in‑state solar projects — the bill subjects their output to the Chapter 22 excise tax starting January 1, 2027, which reduces project-level revenues and could affect financing and PPAs.
- Nuclear generating facilities — the repeal of the separate nuclear chapter moves taxation into Chapter 22 and could change compliance logistics or timing; any regulatory or contractual expectations set under the repealed chapter may require renegotiation or administrative transition.
- Utilities and purchasers under long-term contracts — could face pass-through disputes or renegotiation pressure if the tax treatment change alters the economics of contracted output, especially for projects that began under different statutory assumptions.
- Department of Revenue and state agencies — bear one-time implementation costs (rulemaking, guidance, form redesign) and will need to resolve drafting inconsistencies before collecting accurately.
Key Issues
The Core Tension
The bill balances the state’s interest in broadening and simplifying its production-tax base against the risks of imposing a production tax framework designed for wind onto solar and nuclear technologies — a choice that can create administrative ambiguity, economic disruption for projects built under prior rules, and complex allocation questions for modern, hybrid generation configurations.
The bill consolidates tax coverage but leaves several drafting and implementation gaps. Multiple provisions retain wind-specific phrasing or legacy dates (e.g., references to production for sale on or after January 1, 2012), so administrators and taxpayers will need explicit guidance to determine whether those references were intended to remain exclusive to wind or to be updated for solar and nuclear.
The repeal of the separate nuclear chapter removes the prior statutory home for nuclear taxation but creates transitional questions about credits, liabilities, or grandfathered arrangements set under the repealed provisions.
Operationally, applying the tax at the point of interconnection and measuring it per megawatt-hour raises allocation issues for hybrid projects (co-located solar+storage), distributed generation that aggregates output behind a single interconnect, and for facilities that interconnect to networked systems where MWh accounting crosses ownership boundaries. The three-year exemption tied to "generating facility" is simple on its face but can produce edge disputes for phased builds, repowered installations, or reactors with extended commissioning periods.
Absent explicit rate language or cross-references, the tax’s fiscal effect will depend on how DOR maps Chapter 22’s existing rate mechanics to newly captured generation.
