Maryland Energy Insurance

Last Updated: July 29, 2026

What Does Energy Insurance Cover for Maryland Businesses?

Maryland energy insurance from The Allen Thomas Group is commercial coverage built for Maryland solar, wind, legacy oil and gas, and utility contracting businesses, protecting against pollution, equipment, contractual liability, and technology exposures a standard business policy does not cover. Energy activity in Maryland today centers on solar development, offshore and land-based wind, propane and heating oil distribution, and a small residual base of legacy conventional oil and gas wells in the western part of the state, since the 2017 statewide fracking ban ended new shale development. Each of these operations 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 Maryland since 2003 and knows which carriers price Maryland energy risk correctly across all three layers, and which exclude classes of business in ways that leave real coverage gaps.

Maryland State-Mandated Coverage

Maryland requires nearly every employer with one or more employees to carry workers’ compensation coverage, regardless of whether staff work full-time, part-time, or seasonally. The main exceptions are agricultural employers with fewer than three employees or less than $15,000 in annual payroll, and sole proprietors or partners with no employees. Coverage can be purchased from a private carrier or from Chesapeake Employers’ Insurance Company, Maryland’s competitive state-chartered workers’ compensation insurer, which writes coverage statewide and competes directly with private carriers rather than serving purely as a market of last resort.

Operating without workers’ compensation in Maryland is a misdemeanor, and penalties for noncompliance have grown steep: fines up to $25,000 per violation, with corporate officers potentially held personally liable, on top of imprisonment exposure for a convicted employer. Employers must also report workplace injuries within 10 days and begin paying or formally contesting a claim within 30 days, or face additional penalties of 20 to 40 percent on top of the original claim cost. This applies to solar installation crews, wind technicians, and propane delivery drivers the same as any other Maryland employer.

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

Beyond Maryland’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. This remains relevant to the small number of legacy conventional wells still operating or being plugged in western Maryland’s Garrett and Allegany counties, and to any working-interest owner named on a joint operating agreement tied to those wells.

How a Maryland 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 incidents, 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 legacy well site or an aboveground storage tank, 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 Maryland worksites or staged on-site before installation, a different exposure than a fixed piece of machinery failing in place. This matters as much for a solar EPC crew moving racking and inverters between job sites as it did historically for oilfield equipment.

Machinery Breakdown & Property

Machinery breakdown and property coverage repairs or replaces damaged generation units, substations, transformers, and plant structures, the fixed, high-value infrastructure that a standard property form often underinsures, whether that infrastructure is a legacy gas facility or a newly interconnected solar array.

Cyber and Technology Risk for Maryland 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 Maryland 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 Maryland energy business running automated grid, metering, or control technology, not just for office-based data breach exposure.

What Other Insurance Do Maryland Energy Businesses Need?

Alongside the state-mandated and energy-specific coverages above, most Maryland 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 Maryland field sites, a real exposure for any energy business running its own fleet of solar installation trucks, wind service vehicles, or propane delivery trucks 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 substation failure, a storm-related shutdown, or a machinery breakdown at a facility. For energy projects with long interconnection lead times, this is often the difference between weathering an incident and losing the project timeline 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 pollution event, a vehicle accident involving a service crew, 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. EPC (engineering, procurement, construction) contracts in Maryland solar and wind development, and interconnection agreements with the local utility, routinely require the contractor to indemnify the project owner or utility, which means your policy needs additional insured and contractual liability language that actually matches what you signed.

• Workers’ compensation (private carrier or Chesapeake Employers’)
• 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 EPC and interconnection agreements

Maryland 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, substations, transformers, and plant structures, the fixed infrastructure of an energy operation as opposed to equipment in transit.

Chesapeake Employers’ Insurance Company

Maryland’s competitive, state-chartered workers’ compensation insurer, writing coverage statewide alongside private carriers rather than serving only as a market of last resort. Most Maryland employers with one or more employees must carry workers’ compensation from a private carrier or from Chesapeake Employers’.

Certificate of Public Convenience and Necessity (CPCN)

The approval Maryland’s Public Service Commission requires before certain generating stations and transmission lines can be built, generally triggered for solar facilities exceeding 2 megawatts AC capacity and land-based wind facilities exceeding 70 megawatts, unless the project qualifies for a CPCN exemption and falls back to local zoning review instead.

How Much Does Energy Insurance Cost in Maryland?

Premium for Maryland energy insurance depends heavily on the type of operation. A legacy oil and gas well operator carrying 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 Maryland 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 Maryland businesses (actual pricing varies by revenue, operations, and claims history)

Business Type	Typical Annual Premium Range	Primary Cost Drivers
Legacy Oil & Gas Well Operations	$6,000 – $25,000+	Control of well exposure, pollution liability, well plugging/reclamation risk
Solar / Wind Installation & Development	$3,500 – $15,000	Equipment values, completed operations, interconnection contract terms
Utility & Infrastructure Services	$5,000 – $20,000	Equipment breakdown, contractual liability, high-hazard class codes
Propane & Heating Oil Distribution	$4,000 – $12,000	Product liability, fleet exposure, storage/handling risk
Energy Brokerage / Advisory	$1,500 – $5,000	Professional liability and cyber exposure, lower physical risk

Well Bonding and Maryland’s Oil and Gas Regulatory Landscape

Maryland is not an active oil and gas drilling state today. In 2017, the General Assembly passed a permanent statewide ban on hydraulic fracturing, making Maryland the first state with meaningful shale gas reserves to prohibit the practice through legislation, largely ending new well development in the Marcellus Shale counties of Garrett and Allegany in western Maryland. Because of the ban, there is no active tiered well-bonding regime comparable to major producing states, and this page does not include a well bond calculator, since building one would overstate a regulatory exposure that does not meaningfully apply here.

What does remain on the books is the Maryland Department of the Environment’s Mining Program permitting process for any conventional oil or gas exploration, production, or well-plugging activity that does still occur, along with the Department’s broader surface mining bonding rules. Performance bonds for well drilling and plugging operations under Maryland’s mining regulations can run up to $100,000 per well or $500,000 as a blanket bond, covering proper plugging and site reclamation. Any Maryland energy business still involved in legacy well maintenance, plugging, or site remediation should confirm current bonding and permitting requirements directly with MDE’s Mining Program before beginning work, rather than assume the drilling-era rules still apply as written.

• Hydraulic fracturing banned statewide since 2017
• No active tiered well-bonding regime, unlike major producing states
• MDE Mining Program still permits legacy well plugging/reclamation work
• Well drilling/plugging bonds up to $100,000 per well or $500,000 blanket
• Confirm current requirements directly with MDE before legacy well work
• Separate from pollution and control-of-well insurance coverage

Solar and Wind Facility Siting in Maryland

Maryland’s primary energy regulatory hook today is not well bonding, it is generation facility siting. The Maryland Public Service Commission requires a Certificate of Public Convenience and Necessity (CPCN) before certain generating stations and transmission lines can be constructed. For solar, that threshold is a facility with an alternating current generating capacity exceeding 2 megawatts; projects below that size are instead subject to local zoning approval rather than PSC review. For land-based wind, projects can qualify for a CPCN exemption if generating capacity does not exceed 70 megawatts. Community solar projects follow a related rule: an individual project over 2 MW needs a CPCN, and co-located projects with combined capacity over 14 MW at one location trigger the same review.

For a developer or EPC contractor, that means a mid-size Maryland solar or wind project can clear local zoning without ever touching PSC review, while a larger utility-scale project needs a full CPCN application, a process that has averaged well over a year in recent PSC data, plus a $10,000 filing fee. Confirming which track your project falls into before finalizing project insurance and contractual liability limits avoids a costly assumption either way.
