Illinois Landlord and Tenant Energy Responsibilities: Who Should Be Managing Commercial Energy Contracts
Illinois Landlord and Tenant Energy Responsibilities: Who Should Be Managing Commercial Energy Contracts
Walk into any lease negotiation for Illinois commercial real estate, and energy costs are almost certainly discussed. They just aren't always discussed well. Utility responsibility clauses are some of the most financially impactful provisions in a commercial lease — and some of the most poorly understood by both parties at the time of signing.
For commercial landlords, the question is how to structure utility responsibilities to protect their net operating income, avoid disputes with tenants, and capture the cost reduction opportunities that the Illinois competitive energy market makes available. For commercial tenants, it's about understanding exactly what you're on the hook for, avoiding surprise utility charges at reconciliation time, and ensuring you have the mechanisms to manage and reduce the energy costs attributable to your space.
This guide clarifies the Illinois commercial energy landscape for both sides of the leasing relationship — with practical guidance on contract structures, legal responsibilities, procurement strategies, and the specific provisions that protect both landlords and tenants.
Illinois Landlord vs. Tenant Energy Responsibilities: What Every Commercial Property Owner Must Know
The starting point for understanding energy responsibilities in any Illinois commercial lease is the lease type. The four most common commercial lease structures handle utility responsibilities very differently.
Gross Lease
In a gross lease, the tenant pays a fixed base rent and the landlord is responsible for all operating expenses — including utilities. The landlord pays the electricity and gas bills; the tenant has no direct exposure to utility cost fluctuations.
Energy management implication for landlords: You own the utility cost. Proactive energy procurement through competitive ARES suppliers, energy efficiency investments, and demand management all flow directly to your net operating income (or cost). Competitive procurement that saves 8% on electricity supply directly improves your NOI by the same amount.
Energy management implication for tenants: Your utility cost is embedded in base rent. You have limited direct incentive to reduce energy consumption (since you pay the same rent regardless of how much electricity you use). However, this may also mean your landlord is motivated to minimize utility costs and may do so through operational means that affect your comfort or operations.
Triple Net (NNN) Lease
In a NNN lease, the tenant pays base rent plus all operating expenses — including utilities — directly or through pass-through charges from the landlord. This is the most common structure for single-tenant commercial buildings (retail, industrial, freestanding commercial).
Energy management implication for landlords: You're largely insulated from utility cost volatility, but the quality of your tenant's energy management may affect building systems and long-term maintenance. If you control supply procurement on behalf of the tenant (through a master utility account), your procurement decisions directly affect their operating costs.
Energy management implication for tenants: You own the utility cost entirely. Competitive energy procurement, demand management, efficiency improvements — all of these go directly to your bottom line. This lease structure creates the strongest incentive for tenants to manage energy aggressively.
Modified Gross Lease
A modified gross lease negotiates specific utility responsibilities between landlord and tenant, with the details varying by property and deal. Common structures include: landlord pays electricity for common areas; tenant pays for their own space; or tenant pays utilities up to a base year amount, with increases above that base passed through.
Energy management implication: Specific to the negotiated provisions. Understanding exactly what's included and excluded is critical before signing.
Net Lease with Caps
In response to tenant concern about utility cost volatility, some leases include a cap on annual utility cost escalation — e.g., "utility expenses passed through to tenant shall not increase by more than 5% annually." This provides tenants with some cost predictability while preserving the landlord's ability to pass through actual costs.
Who Pays for Commercial Energy in Illinois? Breaking Down Lease Agreements and Utility Obligations
Regardless of lease type, several specific utility scenarios create confusion between landlords and tenants that should be resolved before signing.
Direct Utility Accounts vs. Submetered Accounts
Direct utility account (tenant's name): The tenant has their own ComEd or Ameren account and pays the utility directly. They can choose their own ARES supplier independently and receive all the benefits of competitive procurement without any involvement from the landlord.
Landlord-controlled master meter with submetering: The landlord has the utility account. A submetering system measures each tenant's consumption, and the landlord bills each tenant for their share. The tenant cannot independently shop the ARES market — the landlord's supply choice governs the rate.
Landlord-controlled master meter without submetering: The landlord pays the utility bill and allocates utility costs among tenants based on square footage or some other formula. Individual tenant consumption is not measured. This creates potential for unfair allocations and disputes.
The ICC's position: The Illinois Commerce Commission has specific rules about energy resale by landlords. Landlords serving multiple tenants through a single utility account must comply with applicable ICC regulations and generally cannot charge tenants more than the actual per-unit cost from the utility, plus a reasonable administrative fee.
Common Area Energy Costs
For multi-tenant buildings, common area energy costs (lobbies, corridors, parking lots, shared HVAC) are typically the landlord's direct responsibility, but are often passed through to tenants as a component of CAM (Common Area Maintenance) charges.
Key questions tenants should ask before signing:
- What is the basis for the common area utility cost allocation?
- Is common area utility cost capped or escalation-limited?
- Can tenants audit common area utility bills?
- What efficiency standards apply to landlord-managed common area systems?
How to Structure Commercial Energy Contracts in Illinois to Protect Landlords and Tenants
Recommendations for Landlords
1. Implement competitive energy procurement at the building level
For any building where the landlord controls the utility account (NNN with master meter, gross lease), competitive ARES procurement for the building's supply is the most direct way to reduce utility costs. A typical 10-unit commercial strip center consuming 200,000 kWh/month can save $15,000–$20,000 annually through competitive supply procurement.
These savings flow differently depending on lease structure:
- In gross leases: directly to landlord NOI
- In NNN leases with master-meter submetering: either to landlord (if rate is fixed to tenants) or to tenants (if actual cost is passed through)
2. Standardize submetering in all new leases
Individual submetering is more expensive to install initially but creates significant long-term benefits: accurate cost allocation, audit-friendly billing, and the ability to demonstrate to tenants that they're being billed fairly. The ICC's submetering requirements apply to landlords billing tenants for electricity in multi-tenant buildings.
3. Include an energy procurement clause in leases
Lease language should explicitly authorize the landlord to procure electricity supply from competitive ARES suppliers on behalf of the building and pass through actual commodity costs. Without this authorization, there may be ambiguity about whether a landlord-initiated supplier switch is permissible or constitutes a unilateral change to a tenant's utility costs.
4. Create a capital improvement coordination process
When landlords undertake energy efficiency improvements (LED lighting, HVAC upgrades), the lease should specify how utility cost savings are allocated. Does the landlord retain the savings to recoup their investment? Are savings shared with tenants? Is the investment recouped through a specific capital pass-through? Clarity prevents disputes.
Recommendations for Tenants
1. Negotiate a utility cost cap or base year provision
If you're signing a NNN lease or modified gross with utility pass-throughs, negotiate for protection against dramatic cost increases. Options include:
- Annual escalation cap (e.g., "utility pass-throughs shall not increase by more than 7% annually")
- Base year structure (tenant pays utilities to the base year level; increases above base are the tenant's responsibility with a cap)
- Fixed utility allowance built into rent (landlord's risk above the allowance)
2. Request audit rights for utility cost pass-throughs
Any lease that includes landlord-managed utility costs passed through to tenants should include explicit tenant audit rights — the right to review utility bills and submetering records supporting the pass-through charges. Without audit rights, tenants have no mechanism to verify they're being billed correctly.
3. Negotiate the right to install direct submetering if not already in place
If your space is not currently submetered and costs are allocated by square footage, negotiate the right to install your own submeter at your expense. Square footage allocation may significantly over- or under-allocate costs relative to actual consumption, and a submeter provides objective billing accuracy.
4. Clarify energy supplier choice rights in the lease
If you'll have your own utility account, ensure the lease explicitly confirms your right to choose an ARES supplier for your space's electricity supply. In some buildings, landlords attempt to restrict tenants to utility default service through lease language — which may conflict with Illinois deregulation law but creates administrative friction if not addressed upfront.
Save Thousands on Illinois Commercial Energy Costs: Expert Tips for Landlords and Business Tenants
For Landlords: The Procurement Opportunity
A landlord managing 10 commercial tenants in a strip center, with a master utility account at 3,000,000 kWh/year, who has never switched from utility default service is leaving approximately $30,000–$60,000 in annual savings uncaptured. That represents meaningful NOI improvement — equivalent to a significant increase in effective rent.
The process is identical to any commercial energy procurement: gather usage data, work with a commercial energy broker, solicit competitive bids from ARES suppliers, execute the best contract, and pass through actual supply costs to tenants per lease terms.
For multi-site landlords with properties across northern and central Illinois, portfolio procurement across ComEd and Ameren territories can capture additional volume-based pricing advantages. See multi-location Illinois business energy contracts for the portfolio procurement playbook.
For Tenants: Know What You're Paying and Compare It to the Market
If you're a commercial tenant in Illinois with your own utility account, you have full competitive market rights and should be treating energy procurement with the same rigor as any other operating cost management. The steps are straightforward: know your contract status, benchmark against the market, switch when competitive rates save meaningful money.
If your utility costs flow through a landlord-managed account, your leverage is primarily through lease negotiation and audit rights. On renewal, push for:
- Caps on utility cost pass-throughs
- Audit rights to verify landlord billing accuracy
- Authorization for your own submetering if currently allocated by square footage
- Landlord commitment to pursue competitive energy procurement (which reduces your costs if you're billed at actual cost)
Conclusion: Clear Responsibilities, Collaborative Management
Illinois commercial energy costs don't have to be a source of landlord-tenant conflict. Clear lease language, transparent billing practices, audit rights, and a shared interest in keeping utility costs as low as possible create the foundation for a productive energy management relationship.
The competitive Illinois energy market is an asset for both parties: landlords who procure electricity competitively reduce building operating costs, improve NOI, and can offer tenants more attractive all-in occupancy economics. Tenants with direct utility accounts who shop the ARES market reduce their operating costs and improve profitability.
The key is starting with clear, well-drafted lease language that specifies exactly who manages what — then executing competitive procurement aggressively on whichever side of the relationship owns the utility cost.

Frequently Asked Questions
QWho is responsible for commercial energy costs in an Illinois lease?
Responsibility depends on the lease structure. In a gross lease, the landlord pays utilities as part of base rent. In a net lease (NNN), the tenant is responsible for utilities directly. In a modified gross lease, responsibilities are split and specifically negotiated. The lease agreement is the controlling document — commercial tenants and landlords should review it carefully before signing.
QCan a commercial tenant in Illinois choose their own energy supplier?
This depends on whether the tenant has a direct utility account in their name. If the tenant has their own meter and utility account, they can choose an ARES supplier independently. If the landlord controls the meter and submeters tenants, the landlord's supplier choice governs the tenant's supply cost — the tenant can't independently shop the market.
QWhat is submetering in a commercial lease and how does it work?
Submetering is where the landlord installs individual meters for each tenant space that measure electricity consumption separately. The landlord pays the utility's bill and then bills each tenant for their proportional usage — either at actual cost, cost-plus, or at a rate that includes a management fee. Submetering is common in multi-tenant buildings and allows more accurate cost allocation than square footage-based proration.
QWhat is a 'pass-through' of utility costs in an Illinois commercial lease?
A utility pass-through is a lease provision where utility costs are passed from the landlord to the tenant, either as a direct bill, as part of a CAM (Common Area Maintenance) reconciliation, or as a separate utility charge reconciled annually. NNN leases typically pass through all utility costs; the specific mechanics and scope of the pass-through should be explicitly defined in the lease.
QShould an Illinois commercial landlord procure energy for all tenants or let tenants manage their own?
It depends on the property configuration. For multi-tenant buildings with a master utility account, landlord-level competitive procurement provides the best pricing through volume aggregation. For properties with individually metered spaces, allowing tenants to manage their own supply can simplify administration. A hybrid approach — landlord manages common area and building systems supply, tenants manage their own leased space — is also common.
QWhat should a commercial tenant in Illinois look for in lease language about energy costs?
Key provisions to review: (1) who is responsible for which utilities, (2) whether utility costs are fixed or subject to reconciliation, (3) the basis for any landlord cost pass-through (actual cost, cost-plus, capped escalation), (4) whether the landlord can procure energy competitively, (5) access rights to meter data for your leased space, and (6) what happens to utility costs during building improvements or landlord energy upgrades.
QCan an Illinois commercial landlord profit from energy resale to tenants?
Illinois law and ICC regulations generally restrict landlords from charging tenants more than the actual cost of electricity purchased from the utility. However, landlords may charge a reasonable administrative/submetering fee. The rules around energy resale in multi-tenant buildings are complex and landlords should consult with an energy attorney to ensure compliance with ICC requirements.
QHow can Illinois commercial landlords and tenants both save on energy costs?
Landlords can save by: implementing competitive energy procurement for master-metered buildings, installing energy-efficient common area systems, negotiating volume pricing across multi-site portfolios, and pursuing utility efficiency rebates for building improvements. Tenants can save by: negotiating favorable utility pass-through caps in leases, independently procuring supply (where they have direct accounts), implementing operational efficiency measures, and installing submetering to verify costs.
