Peoples Gas Chicago Commercial Energy Guide (Natural Gas + Electric)

Peoples Gas commercial bills combine ICC-regulated delivery with competitive supply charges. General service commercial schedules apply to many Chicago offices and retail boxes; larger boilers and central plants may use different classifications. Customer charges, distribution volumetric rates, and surcharges fund system modernization—including accelerated main replacement that affects long-term delivery cost trends.

Chicago businesses often manage multiple meters across tenant spaces. Master-metered buildings need clear CAM language specifying how Peoples delivery escalations pass to tenants. Submetered properties should reconcile tenant factors annually. Review Peoples Gas delivery tariffs when ICC orders interim rate changes.

Supply Choice in the City

Default supply through Peoples works as a fallback but rarely optimizes winter strips. Retail suppliers offer fixed, index, and layered products—compare on identical swing and basis. Align contract start with lease renewals for real estate portfolios to avoid stranded gas contracts when tenants change.

Chicago commercial real estate classes span pre-war masonry loft buildings with steam radiators to Class A glass towers with centralized VAV plants. Peoples Gas delivery cost trends affect NOI directly—underwriting acquisitions without separating delivery escalation from supply market risk has burned investors when ICC approved infrastructure riders during hold periods.

Loop and Near North accounts may share congested alleyway meter access complicating switch logistics; schedule supplier enrollments avoiding winter meter reader access conflicts flagged by Peoples field operations.

Peoples Gas rate design includes riders funding infrastructure replacement—commercial customers pay proportionally to therms but political scrutiny of delivery increases continues through 2025 ICC dockets. Monitor docket outcomes when budgeting multi-year CAM pass-throughs to tenants.

Dual-fuel buildings with electric heat backup should verify gas meters remain appropriately sized if gas load drops—fixed customer charges on underutilized meters inflate $/therm effective cost.

Tax increment financing districts and special service areas in Chicago may include utility-related fees on commercial bills—separate these from Peoples delivery when benchmarking against suburban Nicor accounts.

Chicago TIF districts and special service areas occasionally include utility-related surcharges—property accountants should map these separately from Peoples delivery when allocating CAM. Misclassification inflates comparable analysis against suburban assets on Nicor without equivalent surcharges.

Historic landmark buildings may restrict external equipment placement—affecting heat pump and condensing boiler retrofits that reduce therms. Procurement savings from competitive supply should fund efficiency where envelope constraints limit mechanical options.

Mixed-use towers with retail base and residential upper floors may have complex Peoples rate treatment—verify whether commercial rate schedules apply to entire meter or require allocation agreements with residential condominium associations.

Chicago Department of Buildings boiler permit cycles affect when therm savings begin—do not defer mechanical upgrades while capturing supply savings alone.

South Side industrial buildings with aging low-pressure steam systems lose substantial therms through failed traps—trap audit programs often precede supply RFPs once baseline therms normalize.

ComEd and Peoples Gas bills arrive separately but operational decisions link them. Electrifying domestic hot water, adding heat pumps, or installing kitchen induction shifts therms to kWh. Procurement teams should model scenarios together—not in silos—especially when CEJA incentives push building electrification.

Coordinated RFP Timing

Electric supply contracts often run 24–36 months while gas may be 12–18 months. Staggered expirations create admin drag. Align gas winter strips with ComEd capacity planning windows where possible. A unified advisor can issue parallel RFPs with consistent swing and pass-through definitions.

• Map contract expiration dates for every ComEd and Peoples account in the portfolio.
• Model electrification CapEx impact on both utilities before long gas fixes.
• Use ComEd interval data to identify electric peaks from gas-fired RTU coordination issues.
• Stack ComEd efficiency rebates with Peoples-funded weatherization where programs overlap.

Explore ComEd hourly pricing only after understanding how gas-heated peaks translate to electric auxiliary use on cold mornings. Our broker guide explains margin transparency across dual-fuel RFPs.

ComEd summer peak kW often correlates with gas-heated reheat in older VAV systems—retrocommissioning addressing simultaneous heat/cool can cut both utilities. Chicago Building Decarbonization Working Group discussions may eventually affect new construction gas hookups; long-hold owners should monitor policy for electrification timing even when current systems remain gas-fired.

Tenant electric submetering without gas submeters creates misaligned incentives—landlords pay Peoples while tenants crank heat via electric space heaters. Holistic CAM education reduces inefficiency passthrough disputes at reconciliation season.

ComEd capacity charges from PJM affect total energy spend more than Peoples therms for many Loop offices—yet gas procurement still merits attention because boiler inefficiency raises both fuels simultaneously during shoulder seasons.

Retail portfolios with Chicago flagship plus suburban Nicor sites need territory-specific gas RFPs—Peoples and Nicor basis curves diverge even when NYMEX is shared.

ComEd commercial real estate rates and Peoples gas procurement should appear on one executive dashboard for asset managers—siloed review misses electrification tradeoffs on combined NOI.

ComEd economic development rate agreements for Chicago job creators may include load factor commitments—evaluate whether gas-to-electric switching affects eligibility before electrifying large boiler plants.

Retail energy advisors should present combined therms and kWh dashboards to Chicago asset managers quarterly—seasonal drift in either fuel without explanation signals meter or control issues early.

ComEd transformer upgrades for EV charging in Chicago parking garages increase kWh while Peoples therms may fall—model combined fuel spend when garage electrification projects include heated parking structures.

Loop properties with district steam conversion opportunities should model Peoples therms elimination against ComEd kWh increases before capital committee votes.

Chicago Public Schools and large institutional users on Peoples should verify whether aggregated procurement cooperatives offer better swing terms than individual school RFPs.

High-rise commercial buildings consume gas primarily for boilers, domestic hot water, and sometimes cogeneration. Load profiles peak on winter mornings when recovery from setback collides with tenant arrival. Restaurants add cooking line loads, warewashers, and makeup air heated by gas—creating flat, high baselines from 6 AM to midnight.

Restaurant Gas Intensity

Full-service Chicago restaurants often use 4,000–8,000 therms monthly in winter—$4,000–$12,000 all-in depending on supply pricing. Fast casual with electric cooking shifts mix but still needs DHW and HVAC gas. Group procurement across locations yields supplier volume discounts if swing is pooled intelligently.

High-Rise Considerations

Boiler efficiency degrades without maintenance; 80% efficient steam plants in Loop basements inflate therms per HDD. Condensing boiler retrofits and reset controls often pay back in 3–5 years when Peoples winter supply exceeds $1.00/therm. Pair with hospitality or office tenant engagement on setback policies.

1. 1Submeter kitchen gas where leases allow cost allocation transparency.
2. 2Benchmark therms per cover or per sq ft against ENERGY STAR cohorts.
3. 3Schedule hood cleaning and HVAC coordination—blocked filters increase gas heat recovery load.
4. 4Evaluate heat pump DHW for all-electric new builds in 2025 CEJA incentive windows.

Chicago restaurant groups with 10+ locations should evaluate portfolio gas RFPs aggregating therms while respecting location-specific swing—River North fine dining peaks differ from airport concessions. Suppliers offer portfolio caps on out-of-tolerance penalties when volume variance stays within defined statistical bands across the group.

High-rise domestic hot water recirculation pumps running 24/7 inflate baseload therms; timer and demand controls on pumps frequently save 5–8% without guest impact in hotels studied under ComEd commercial assessments.

Ghost kitchen clusters in Chicago commissaries aggregate gas load unpredictably—subscription-style tenant turnover complicates forward procurement; shorter fixed strips with extension options fit volatile occupancy.

University and hospital campuses in Chicago with central steam plants face decade-long decarbonization horizons—near-term gas procurement still matters for budgets even when long-range plans target electrification.

Hotel portfolios along Michigan Avenue share common boiler plants—gas procurement at master meter level simplifies RFP but requires transparent allocation to property P&Ls for brand-operated vs franchised locations.

Commissary kitchens aggregating delivery restaurant loads create flat gas profiles attractive to suppliers—use that stability to negotiate tighter swing tolerance than individual storefront meters could achieve alone.

Catering commissaries operating 4 AM prep shifts create predawn gas peaks—interval-style AMR data from Peoples helps suppliers price irregular profiles without punitive swing defaults.

Retail landlords passing gas through gross leases still benefit from supply procurement—savings improve NOI even when tenants do not see direct bill credits.

West Loop tech offices retrofitted from warehouse stock often retain oversized gas service—downsize meters after electrification to reduce fixed customer charges where Peoples rules allow.

Chicago's Energy Benchmarking Ordinance requires annual reporting for buildings over 50,000 square feet, with public disclosure increasing reputational stakes. Poor ENERGY STAR scores correlate with higher Peoples therms and ComEd kWh per sq ft—data you can turn into CapEx justification.

High-ROI Gas Measures

• Boiler tune-ups and oxygen trim controls—5–10% therm savings typical.
• Low-flow DHW aerators and recirculation pump controls in hotels.
• Building automation setback for office towers on weekends.
• Window and envelope upgrades reducing heating load in legacy masonry buildings.

ComEd incentives often cover controls and heat pumps that indirectly cut gas. Peoples programs and federal tax credits may apply to qualifying equipment. Document pre-retrofit baselines for incentive validation and benchmarking score improvements.

Upload benchmarking data to our bill analyzer when planning procurement—lower normalized load improves supplier quotes and tenant CAM predictability through 2026.

Chicago Energy Rating System labels and benchmarking scores increasingly appear in leasing marketing—subpar gas intensity scores signal capex coming to prospective tenants. Proactive boiler upgrades before mandatory disclosure cycles protect lease-up velocity in competitive submarkets.

Utility coordination workshops through Chicago Department of Buildings help owners understand simultaneous compliance timelines—benchmarking due dates, energy audit triggers, and retrofit ordinances may stack for the same asset class in 2025–2027 planning windows.

ComEd's commercial assessment programs sometimes identify gas-saving measures during electric audits—ask assessors about heating system tune-ups when scheduling free walkthroughs.

Public benchmarking disclosure lists building scores—underperforming gas intensity relative to peers signals upcoming capital requests to ownership committees.

Energy service companies pitching guaranteed savings should disclose baseline methodology to Chicago benchmarking data—misaligned baselines inflate claimed savings against ESPM scores already public.

Chicago Energy Rating labels influence tenant leasing decisions in competitive submarkets—gas intensity improvements documented through benchmarking reports support renewal negotiations even when landlords pass utilities through gross leases.

Federal Inflation Reduction Act commercial building deduction (179D) may apply to qualifying efficiency projects in Chicago assets—coordinate tax review with Peoples therm reduction documentation from retrofit M&V reports.

1. 1Benchmark in ESPM before efficiency CapEx.
2. 2Prioritize boiler tuning before envelope for quick wins.
3. 3Re-bid gas supply after >10% therm reduction verified.
4. 4Disclose upgrades in tenant CAM estimates annually.

Winter 2025–2026 Peoples delivery riders may adjust independently of NYMEX—budget delivery and supply on separate escalation assumptions in multi-year forecasts.
