Empire District Gas (Liberty Utilities) Rate Selection Guide
Empire District Gas, operating as Liberty Utilities under Algonquin Power & Utilities Corp., distributes natural gas to roughly 43,600 Missouri customers from Joplin. The Liberty My Account portal (rebuilt on the SAP-based Customer First system in April 2024) provides 24 months of usage history and PDF bills; Missouri has no retail gas choice, so there is no EDI program, and third-party access runs through data platforms like Nectar (docs.nectarclimate.com) or formal written requests to Liberty's regulatory team.
Market Overview
Missouri has no retail choice for natural gas — all customers in Liberty's Missouri service area take bundled service directly from Liberty Utilities under Missouri Public Service Commission regulation (Gas Tariff P.S.C. MO. No. 2). This contrasts with Liberty's Massachusetts and New Hampshire gas operations, where deregulation supports supplier choice and NAESB EDI programs. Large commercial customers can access Large Volume Transportation Service for direct pipeline nominations and capacity release.

Current Rate Schedules
Liberty Utilities (Empire District Gas) serves Missouri gas customers under Gas Tariff P.S.C. MO. No. 2, regulated by the Missouri PSC. Non-residential service tiers by annual volume: Small General Service (under 5,000 Ccf/year), Large General Service (5,000-40,000 Ccf), and contract-based Large Volume Service (40,000+ Ccf), each with a parallel transportation schedule (SGST, LGST, LVT) for customers sourcing their own supply. Bills add a Purchased Gas Adjustment (PGA), Weather Normalization Rider (WNAR), and Infrastructure System Replacement Surcharge (ISRS) on top of base rates. Figures below are from recent PSC-filed tariff sheets — confirm current sheets on EFIS or Liberty's rates page; see tariff for current rates.
Effective: January 1, 2024 · Full Tariff Book →
| Schedule | Type | Applicability | Structure | Rate |
|---|---|---|---|---|
| Small General Service (SGS) | commercial | Non-residential firm customers with annual usage under 5,000 Ccf — small storefronts, offices, restaurants. | $25.00 monthly customer charge plus $0.26033/Ccf delivery energy charge for all usage, plus PGA gas cost, ISRS, and WNAR riders. | $0.26033/Ccf delivery + PGA |
| Large General Service (LGS) | commercial | Firm non-residential customers with anticipated annual consumption of at least 5,000 Ccf but less than 40,000 Ccf. | Higher monthly customer charge with a lower per-Ccf delivery charge than SGS (transportation analog LGST: $100 customer charge, $0.21705/Ccf delivery), plus PGA and riders. See tariff for current sales-service figures. | ~$0.217/Ccf delivery (LGST basis) + PGA |
| Large Volume Service (LV) | industrial | Commercial and industrial customers with annual requirements of 40,000 Ccf or more at a single location; service by contract subject to company approval. | $388.00 monthly customer charge, $0.02194/Ccf delivery energy charge, and a demand charge of $0.58000/Ccf of billing demand, plus PGA and riders. | $0.02194/Ccf delivery+ $0.58/Ccf of billing demand |
| Transportation Service (SGST / LGST / LVT) | industrial | Non-residential customers purchasing gas from third-party suppliers; SGST mirrors SGS volumes, LGST covers 5,000-40,000 Ccf/year, LVT covers 40,000+ Ccf/year under written contract. | Delivery-only charges mirroring the sales schedules (e.g., LGST: $100 customer charge + $0.21705/Ccf; LVT: $388 + $0.02194/Ccf + $0.58/Ccf demand) — customers avoid the PGA by sourcing supply. Small/medium transport without telemetry pays a $0.0040/Ccf aggregation charge and ~$0.015/Ccf balancing fee; LVT requires customer-funded telemetry and daily balancing with a $1.25/Ccf penalty on imbalances beyond a 10% tolerance. | — |
Rate Recommendations by Use Case
Industrial plants and large institutions (40,000+ Ccf/year)
Large gas users should contract Large Volume Transportation (LVT) and source their own commodity supply.
LVT delivery costs just $0.02194/Ccf plus the demand charge — the commodity, normally passed through via PGA, becomes a negotiable market purchase. Telemetry is mandatory and daily imbalances beyond 10% incur $1.25/Ccf penalties, so disciplined nominations are part of the deal.
- Budget telemetry installation costs — customers reimburse Liberty's actual equipment and communication costs
- Nominate conservatively and consider the optional expanded-tolerance service to manage the $1.25/Ccf imbalance penalty
- Negotiate billing demand carefully: the $0.58/Ccf demand charge is keyed to it
Mid-size commercial — schools, healthcare, light manufacturing (5,000-40,000 Ccf/year)
LGS-class customers can join transportation via LGST, often through aggregation pools that handle supply procurement.
LGST charges $100/month plus $0.21705/Ccf delivery with modest aggregation ($0.004/Ccf) and balancing (~$0.015/Ccf) fees — no telemetry required. Missouri school districts commonly use aggregation pools under this structure, and the same path works for comparable commercial loads.
- Join an established aggregation pool to spread balancing costs across members
- Compare pooled supply pricing against Liberty's PGA history (posted on the rates page) before committing
- Voluntary telemetry ($11.50 meter administration fee) can replace pooled balancing for steadier loads
Small commercial under 5,000 Ccf/year
Small accounts on SGS have limited rate options; focus on efficiency and rider verification.
At $25/month plus $0.26033/Ccf delivery plus PGA, the bill is volumetric — every Ccf saved returns the full bundled rate. Accounts growing past 5,000 Ccf/year should request reclassification to LGS for the lower unit delivery charge.
- Track annual Ccf against the 5,000 Ccf LGS threshold
- Verify ISRS and WNAR riders on bills against the current PSC-filed sheets
- High-efficiency equipment upgrades cut both delivery and PGA components
Cost Optimization Strategies
Liberty's Empire District Gas tariff offers classic gas cost levers: transportation service to bypass the PGA, volume-tier optimization across SGS/LGS/LV, aggregation pools for mid-size loads, and rider auditing. In a PSC-regulated monopoly territory, supply procurement strategy — not utility switching — is where C&I customers move the needle.
Transportation service conversion
For: Commercial and industrial customers above 5,000 Ccf/year
Customers above 5,000 Ccf/year can replace Liberty's PGA gas cost with directly procured supply via LGST or LVT, paying only tariffed delivery charges ($0.217/Ccf LGST; $0.0219/Ccf + demand LVT). Review PGA history on Liberty's rates page to quantify the spread against market offers.
Volume-tier and demand optimization
For: All non-residential accounts, especially near tier boundaries
Rate class hinges on annual Ccf (5,000 and 40,000 thresholds), and LV/LVT bills carry a $0.58/Ccf demand charge on billing demand. Right-size contract demand to actual peak-day needs and verify classification annually — misclassified accounts overpay on either the customer charge or unit delivery rate.
Balancing and imbalance management
For: All transportation service customers
LVT customers pay $1.25/Ccf on daily imbalances beyond 10% tolerance; small/medium transport customers pay pooled balancing (~$0.015/Ccf). Accurate daily nominations, weather-driven forecasting, and the optional expanded-tolerance service prevent penalties from eroding transportation savings.
Weather normalization and rider auditing
For: All customer classes; high-volume winter loads benefit most
Liberty applies a Weather Normalization Adjustment Rider (WNAR) plus the ISRS infrastructure surcharge. Reconcile winter bills against WNAR mechanics and confirm ISRS percentages match the current PSC-approved level — surcharges reset with PSC filings and errors persist unnoticed.
Load reduction against the full delivered rate
For: All sales-service customers
Boiler tune-ups, steam trap programs, heat recovery, and building envelope work cut Ccf volume exposed to delivery charges, PGA, and riders simultaneously. For SGS accounts paying ~$0.26/Ccf delivery plus commodity, efficiency projects return the full stacked rate.

Frequently Asked Questions
How do commercial customers access Empire District Gas (Liberty) billing and usage data?▾
Register in Liberty My Account at https://myaccount.libertyutilities.com/ (Missouri customers route to state-specific logins). The portal shows the current bill, three months of statements, and 24 months of usage history with monthly/seasonal comparison charts; bills export as PDF only. For data beyond 24 months or special formats, call Customer Care at 1-855-872-3242 (option 2 for Gas) and allow 7-10 business days.
Is interval gas data available from Liberty's Missouri smart meters?▾
Not as downloads. Smart meter deployment is ongoing and My Account exposes near real-time usage views, but 15/30-minute interval exports are not documented. For detailed interval data, call 1-855-872-3242 with your use case (energy audit, equipment sizing, sustainability reporting) and signed authorization if requesting for a third party — expect 10-15 business days for complex retrievals.
Can third parties access Liberty Missouri gas data automatically?▾
Yes, through third-party data platforms. Nectar provides API access to this utility's billing and interval data via customer authorization — see docs.nectarclimate.com. Liberty itself offers no OAuth or Green Button integration. The alternative is a formal letterhead request with customer consent to regulatory.information@libertyutilities.com, with 10-15 business day processing and a likely data sharing agreement.
Why doesn't Empire District Gas support EDI in Missouri?▾
Missouri has no retail choice for natural gas, so all customers take supply directly from Liberty — there are no supplier-switching or marketer-enrollment transactions to support. Liberty does run NAESB EDI programs in its deregulated Massachusetts and New Hampshire gas markets (Liberty.Noms@libertyutilities.com), but those do not apply to Missouri. Billing EDI inquiries go to regulatory.information@libertyutilities.com.
What options exist for large industrial gas customers?▾
Customers on Large Volume Service and Large Volume Transportation Service schedules (Gas Tariff P.S.C. MO. No. 2) may qualify for direct pipeline nominations, demand-side management programs, and capacity release transactions, plus specialized usage and billing reports. Start with Liberty Commercial Services at (417) 625-5100 to review eligibility and execute a service agreement.
Did the 2024 system migration change data access?▾
Liberty migrated to the SAP-based Customer First platform in April 2024, with the mobile app built by Smart Energy Systems LLC. The migration caused temporary billing and data access disruptions, now largely resolved. The new system focused on internal operations — it did not add public APIs, Green Button, or third-party data sharing capabilities.
