Montana Energy Insurance

Last Updated: July 29, 2026

What Does Energy Insurance Cover for Montana Businesses?

Montana energy insurance from The Allen Thomas Group is commercial coverage built for Montana oil and gas, solar, wind, and utility businesses, protecting against pollution, well control, equipment breakdown, and contractual liability exposures a standard business policy does not cover. Energy operations in Montana span oil and gas production concentrated in the Bakken and Williston Basin counties, solar and wind development, utility infrastructure, and propane and fuel distribution, and each carries exposures a standard business owner’s policy does not anticipate. A complete program generally combines three layers: state-mandated coverage, coverages built specifically for energy risk, and the general commercial policies every business needs. The Allen Thomas Group has been licensed in Montana since 2003 and knows which carriers price Montana energy risk correctly across all three layers, and which exclude classes of business in ways that leave real coverage gaps.

Montana State-Mandated Coverage

Montana requires nearly every employer to carry workers’ compensation coverage starting with the first employee hired, with no small-employer exemption for a certain headcount before coverage kicks in. Sole proprietors and certain household or fixed-location owner-operators are exempt, and anyone working as an independent contractor must either carry their own coverage or hold a current Independent Contractor Exemption Certificate from the Montana Department of Labor and Industry. Coverage can be purchased from a private carrier or from the Montana State Fund (MSF), a nonprofit, publicly owned insurer created by the legislature as a genuinely competitive guaranteed-market carrier, not just a market of last resort, that must write a policy for any Montana employer that wants one.

Operating without workers’ compensation in Montana exposes an employer to fines, potential referral to the state’s Uninsured Employers’ Fund, and full personal liability for a workplace injury outside the normal workers’ compensation system. This applies to solar crews, oilfield services teams, and utility contractors the same as any other Montana employer.

What Insurance Do Oil, Gas, and Solar Companies Need in Montana?

Beyond Montana’s state-mandated coverage, energy businesses need a set of coverages built specifically for how energy operations actually fail. These four make up the core of a real energy insurance program:

Operator’s Extra Expense (OEE) / Control of Well

Operator’s Extra Expense, often referred to interchangeably with control of well coverage, pays for blowout response, redrilling costs, and immediate pollution cleanup when a well goes out of control. Working-interest owners, not just the operator of record, often need their own policy under the terms of a joint operating agreement.

How a Montana Control of Well Claim Gets Paid

1. The well operator notifies the carrier immediately once a well control incident occurs.
2. The carrier dispatches an adjuster and, for serious blowouts, a specialized well control contractor to assess and begin response.
3. Redrilling, seepage cleanup, and immediate pollution response costs are documented as they are incurred.
4. Documented costs are submitted to the carrier for review against the policy’s control-of-well and OEE limits.
5. The carrier settles the claim, and coverage responds up to the policy limit for redrilling, cleanup, and related extra expense.

Environmental Pollution Liability

Standard general liability policies typically exclude pollution exposure. Environmental pollution liability covers both sudden contamination events, such as a spill during transport, and gradual contamination, such as slow seepage from a storage tank or legacy well site, from energy extraction, transport, or generation activity.

Equipment / Inland Marine

Inland marine coverage protects mobile equipment, tools, and parts while they are in transit between Montana worksites or staged on-site before installation, a different exposure than a fixed piece of machinery failing in place.

Machinery Breakdown & Property

Machinery breakdown and property coverage repairs or replaces damaged generation units, pipelines, substations, and plant structures, the fixed, high-value infrastructure that a standard property form often underinsures, particularly for equipment operating through Montana’s harsh winter conditions.

Cyber and Technology Risk for Montana Energy Businesses

Modern utility and grid infrastructure runs on industrial control systems and SCADA networks that are genuine targets for malware and ransomware, and a growing share of solar and wind operations rely on remote monitoring and automated control systems with the same exposure. Standard general liability and property policies do not cover a data breach, a ransomware event, or business interruption caused by an attack on your control systems. Cyber liability insurance is a separate, increasingly necessary policy for any Montana energy business running automated grid, metering, or control technology, not just for office-based data breach exposure.

What Other Insurance Do Montana Energy Businesses Need?

Alongside the state-mandated and energy-specific coverages above, most Montana energy businesses also need a standard commercial foundation:

Commercial General Liability (CGL)

Commercial general liability (CGL) protects against third-party bodily injury and property damage claims, the foundation every other coverage on this page layers on top of.

Commercial Auto

Commercial auto coverage insures the trucks and service vehicles moving crews, tools, and equipment between Montana field sites, a real exposure for any energy business running its own fleet across the state’s long rural distances rather than relying entirely on subcontractors.

Business Interruption

Business interruption coverage replaces lost income and ongoing expenses if operations shut down because of a covered physical disaster or an equipment failure, such as a control-of-well incident or a machinery breakdown at a plant. For energy projects with long lead times, this is often the difference between weathering an incident and losing the contract behind it.

Commercial Umbrella

Energy claims are large enough, and frequent enough, that a standard general liability or auto policy’s underlying limits can be exhausted by a single serious incident: a control-of-well blowout, a major pollution event, or a catastrophic equipment failure that damages third-party property. Commercial umbrella coverage sits above those underlying limits and fills in coverage gaps the primary policies leave open, which is why it is treated as close to essential, not optional, for energy accounts rather than a general commercial add-on.

Contractual liability matters just as much as the coverages above. Master service agreements in oilfield services and EPC (engineering, procurement, construction) contracts in solar and wind development routinely require the contractor to indemnify the project owner, which means your policy needs additional insured and contractual liability language that actually matches what you signed.

• Workers’ compensation (private carrier or Montana State Fund)
• Operator’s Extra Expense / control of well
• Environmental pollution liability
• Equipment / inland marine
• Machinery breakdown & property
• Cyber and technology risk for grid/SCADA systems
• Commercial general liability (CGL)
• Commercial auto
• Business interruption
• Commercial umbrella (limits exhaustion protection)
• Contractual indemnity in MSAs and EPC contracts

Montana Energy Insurance Terms Defined

Operator’s Extra Expense (OEE)

Coverage often bundled with or used interchangeably with control of well insurance, paying for blowout response, redrilling costs, and immediate pollution cleanup when an oil or gas well goes out of control. Working-interest owners, not just the operator of record, often need their own policy under the terms of a joint operating agreement.

Environmental Pollution Liability

Coverage for both sudden contamination events, such as a transport spill, and gradual contamination, such as slow seepage from a storage tank or legacy site, arising from energy extraction, transport, or generation activity. Standard general liability policies typically exclude this exposure entirely.

Equipment / Inland Marine

Coverage for mobile equipment, tools, and parts while in transit between worksites or staged on-site, distinct from machinery breakdown coverage for equipment that is already installed and in fixed operation.

Machinery Breakdown & Property

Coverage that repairs or replaces damaged generation units, pipelines, substations, and plant structures, the fixed infrastructure of an energy operation as opposed to equipment in transit.

BOGC Plugging and Reclamation Bond

A depth-tiered financial security requirement administered by the Montana Board of Oil and Gas Conservation under Administrative Rule of Montana 36.22.1308: single-well bonds of $1,500, $5,000, or $10,000 depending on well depth, or a $50,000 multiple-well bond covering all of an operator’s producing wells.

Montana State Fund (MSF)

A nonprofit, publicly owned workers’ compensation insurer created by the Montana legislature as a competitive guaranteed-market carrier. MSF must write a policy for any Montana employer seeking coverage and competes directly alongside private carriers, rather than acting solely as a market of last resort.

How Much Does Energy Insurance Cost in Montana?

Premium for Montana energy insurance depends heavily on the type of operation. An oilfield services contractor working under MSAs with control-of-well exposure pays very differently than a rooftop solar installer or a propane distributor. The ranges below are illustrative starting points based on typical Montana operations; actual pricing depends on payroll, revenue, claims history, and the specific carrier’s appetite for your class of business.

Illustrative annual energy insurance premium ranges for Montana businesses (actual pricing varies by revenue, operations, and claims history)

Business Type	Typical Annual Premium Range	Primary Cost Drivers
Oil & Gas Production / Oilfield Services	$7,500 – $30,000+	Control of well exposure, pollution liability, high-hazard payroll
Solar / Wind Installation & Development	$3,000 – $12,000	Equipment values, weather exposure, completed operations
Utility & Infrastructure Services	$4,500 – $18,000	Equipment breakdown, contractual liability, high-hazard class codes
Propane & Heating Oil Distribution	$3,500 – $10,000	Product liability, fleet exposure, storage/handling risk
Energy Brokerage / Advisory	$1,500 – $5,000	Professional liability and cyber exposure, lower physical risk

Oil & Gas Well Bonding Requirements Under Montana Law

Anyone who owns or operates a producing oil, gas, or underground injection control well in Montana must post a plugging and reclamation bond with the Montana Board of Oil and Gas Conservation (BOGC) before a permit to drill or a change-of-operator request can be approved, under Administrative Rule of Montana 36.22.1308. The bond guarantees that each well is properly plugged and the surface location restored once it can no longer be used for the purpose it was drilled.

Montana’s single-well bond amount is tiered by drilled depth: $1,500 for wells 2,000 feet deep or less, $5,000 for wells between 2,001 and 3,500 feet, and $10,000 for wells 3,501 feet deep or more. Operators running multiple producing wells can instead post a single $50,000 multiple-well bond that covers every well in place of individual single-well bonds, and the Board can require a higher amount if it determines additional surety is needed to guarantee proper plugging. Domestic gas wells fall under a separate bonding schedule set out in Section 82-11-163, MCA. This bond is separate from, and in addition to, the pollution and control-of-well insurance coverage a well operator needs.

• $1,500 single-well bond, 2,000 feet or less
• $5,000 single-well bond, 2,001 – 3,500 feet
• $10,000 single-well bond, 3,501 feet or more
• $50,000 multiple-well bond covers all producing wells
• Filed with the BOGC before a permit to drill is approved
• Separate from pollution and control-of-well coverage

Solar and Wind Facility Siting in Montana

Montana’s Major Facility Siting Act (MFSA), administered by the Montana Department of Environmental Quality, requires a state Certificate of Compliance for large transmission lines over 69 kV that exceed 10 miles in length above 230 kV, and for hydroelectric or geothermal generating facilities capable of producing 50 megawatts or more. Notably, the statutory definition of a “facility” under MFSA does not include wind farms, solar farms, or natural gas or coal-fired generating units, so most solar and wind projects are reviewed and permitted at the county or city government level rather than through state MFSA review, unless the developer specifically petitions to have a project reviewed under MFSA instead.

Separately, the Montana Public Service Commission (PSC) does not site individual generation projects; its role is overseeing long-term resource planning for investor-owned utilities, requiring each utility to file a plan detailing how it intends to meet future customer demand. For a solar or wind developer, that means confirming which local government permitting process applies, and whether a large associated transmission line triggers MFSA review, is part of building a real Montana energy insurance and risk program, not an assumption to skip.
