Does Montana Have Community Solar Laws?

Montana does not currently have a comprehensive statewide law that broadly enables shared solar programs across all utilities. While there have been legislative efforts to create a structured framework for Montana community solar, these attempts have not resulted in a fully implemented statewide program.

One of the most notable proposals was the Montana Solar Shares Act, which aimed to establish a formal system for developing and subscribing to a community solar project. The proposal would have required utilities to support shared solar facilities and provide bill credits to subscribers based on their share of energy production. However, because this legislation was not enacted, Montana does not have a mandatory statewide program in place.

Despite the absence of a uniform policy, community solar does exist in Montana through utility-led and cooperative-driven initiatives. Electric cooperatives, in particular, have taken the lead in offering shared solar options to their members. These programs operate independently and are not governed by a single statewide structure.

In terms of low-income participation, Montana does not currently have standardized policies requiring utilities to provide dedicated access, discounts, or reserved capacity for lower-income households in community solar programs. Some cooperative programs may offer informal participation opportunities, but there is no consistent statewide approach to ensuring equitable access.

What is Community Solar?

Community solar is a shared renewable energy model that allows multiple participants to benefit from a single solar installation located off-site. Instead of installing solar panels on their own property, subscribers receive credits on their electricity bills based on the energy generated by their portion of the system.

This structure explains how community solar works, a centralized solar facility, often referred to as one of several community solar farms, generates electricity and feeds it into the grid. Each subscriber is assigned a share of that energy production, which is then reflected as bill credits.

Community solar is especially useful for people who cannot install solar panels themselves. This includes renters, homeowners with shaded roofs, and individuals who may not want to make the upfront investment required for rooftop systems. In Montana, where properties can be rural or have varying solar conditions, shared solar provides an accessible alternative to residential solar.

Compared to rooftop installations, community solar removes the need for installation, maintenance, and equipment ownership. Subscribers simply participate in the energy output of a shared system, making community solar energy easier to adopt for a wide range of users.

Another advantage is flexibility. Participants can often choose how much energy they want to subscribe to, allowing them to match their participation to their electricity usage.

Why Community Solar?

Community solar offers a range of advantages for homeowners, renters, and businesses. Accessibility is one of the most important reasons people choose community solar. It allows individuals to participate in renewable energy without needing to install equipment on their property. This is particularly valuable in Montana, where geographic and structural factors may limit rooftop solar adoption.

For homeowners, community solar provides convenience. There is no need to manage installation, permitting, or maintenance. Instead, they can subscribe to a community solar project and receive bill credits directly. Renters benefit significantly from community solar, they can access solar energy without modifying their living space. This flexibility is one of the key benefits of community solar, especially in areas where renting is common. Small businesses can also take advantage of shared solar. By subscribing to a portion of a solar facility, they can offset part of their electricity usage without making a large capital investment.

Community solar also contributes to local energy development. By supporting shared solar projects, participants help expand renewable energy capacity within Montana, which can reduce reliance on traditional energy sources and promote a more diversified energy mix.

Are there Community Solar Projects in Montana?

Yes, but availability is limited and largely dependent on electric cooperatives rather than investor-owned utilities.

Montana has fewer than five notable shared solar programs currently in operation. Examples include programs offered by Missoula Electric Cooperative and Ravalli Electric Cooperative, as well as other smaller cooperative-led initiatives. These programs tend to be modest in scale and are designed to serve members within specific service areas rather than the entire state.

Participation is not universal. Not every Montana resident can join a community solar program, as eligibility depends on the utility provider. Customers served by electric cooperatives are more likely to have access, while those served by investor-owned utilities may have fewer options. To sign up, residents typically need to check with their local utility or cooperative. If a program is available, they can subscribe to a share of the solar installation, often based on a set number of panels or a percentage of the system’s output.

Because the market is still developing, availability can be limited, and some programs may have waiting lists or restricted enrollment periods.

How Does Community Solar Work in Montana?

In Montana, community solar programs operate by connecting a shared solar facility to the local utility grid. Electricity generated by the system is distributed through the grid, and subscribers receive credits based on their share of production.

Subscribers are usually assigned a portion of the solar array, either through panel ownership or a subscription model. The electricity produced by that share is tracked and converted into bill credits. If a subscriber uses more electricity than their share generates, they pay for the remaining balance. If their share produces more electricity than they use, the excess is credited to their account for future use. This setup allows participants to offset their electricity costs without installing their own solar panels. It also simplifies participation by removing the need for maintenance or system management.

Community solar projects may also benefit from broader renewable energy incentives at the developer level. These incentives can help support the development of new projects and influence subscription pricing over time.

How Much Does Community Solar Cost in Montana?

Montana’s community solar market is still small and decentralized, so there is no standardized statewide pricing structure. Costs vary depending on the specific program offered by a utility or cooperative.

Most programs follow one of two pricing models, a monthly subscription fee or a one-time purchase of a solar share. Cooperative programs often allow members to either buy into the system or pay for access through a recurring fee.

This table reflects the general range of community solar costs in Montana.

The cost typically covers access to the shared solar facility, including installation, maintenance, and administrative expenses. Unlike residential solar, there is no need for a large upfront investment in equipment, though some programs may offer ownership-style options.

It is important to note that community solar in Montana is not always designed to provide immediate financial savings. In many cases, the primary benefit is access to renewable energy rather than significant cost reductions. Over time, participants may see savings depending on electricity rates and system performance.

When evaluating a program, residents should consider subscription fees, expected bill credits, contract terms, and flexibility. These factors play a key role in determining the overall value of participating in a community solar program in Montana.
