Current Rate Schedules
PECO's commercial and industrial electric service is delivered under three principal non-residential schedules in Tariff Electric Pa. P.U.C. No. 8: Rate GS (General Service), Rate PD (Primary-Distribution Power), and Rate HT (High-Tension Power). All charges are distribution-only; generation supply is competitive (PA Power Switch) or provided through PECO's default Generation Supply Adjustment (Procurement Classes 2 and 3/4). Distribution rates were reset effective January 1, 2025 following the PUC-approved rate case settlement, and base rates are updated semi-annually (June 1 / December 1) for supply adjustments. Commercial and industrial gas distribution service is taken under Rate GC (General Service - Commercial and Industrial) in Gas Pa. P.U.C. No. 6.

|---|---|---|---|---|
| Rate GS - General Service | Commercial/Industrial secondary electric | Offices, professional, commercial or industrial establishments, governmental agencies, farms and other non-residential applications taking single-phase or polyphase secondary service.

Jan 1, 2025)+ $11.35 per kW of billed demand; Fixed Distribution Service Charge $74.66/month polyphase, $31.20 single-phase with demand, $24.47 single-phase without demand (eff. Jan 1, 2025) |
| Rate PD - Primary-Distribution Power | Commercial/Industrial primary electric | Larger commercial and industrial customers (generally peak demand over 100 kW) taking service at standard primary voltage (nominally 2,400V or 4,160V, 3-phase). Used by high- and low-load-factor commercial and industrial accounts. | Demand-based primary distribution schedule: Fixed Distribution Service Charge plus Variable Distribution Service Charge with per-kW demand component and per-kWh charge; non-bypassable distribution charges apply regardless of supplier. Specific published figures not extracted; see tariff book. | Per published Rate PD pages of Tariff Electric Pa. P.U.C. No. 8 (eff.

Sales or transportation (capacity release) options available. | Variable Distribution Charge declining block (historical filed figures ~$4.39/Mcf first block, ~$3.07/Mcf additional); current GC distribution prices updated June 1, 2025 — see gas tariff+ None (volumetric Mcf-based) |

Historical Rate Trends
PECO filed electric and gas distribution rate increases on March 28, 2024. The PA PUC approved a settlement on December 12, 2024 effective January 1, 2025, reducing the electric request from ~$464M to $354M (a 23.7% reduction from request) and the gas request from ~$111M to $78M.
January 1, 2025
PUC-approved electric distribution rate increase; $354M revenue increase (reduced from $464M requested). Typical residential bill rose ~10%; C&I distribution charges increased correspondingly (GS FDSC polyphase set at $74.66, demand $11.35/kW).
~10% typical (residential reference); C&I varies by scheduleJanuary 1, 2025
PUC-approved gas distribution rate increase; $78M revenue increase (reduced from $111M requested). Typical residential gas bill rose ~12.5%. Residential customer charge rose 10.2% ($14.25 to $15.70).
~12.5% typical (residential reference)Overall trend: Rising — distribution rates increased January 1, 2025; PECO has signaled a further electric rate request targeting 2027.
Next expected change: PECO agreed not to file another gas rate increase before March 16, 2026; a further electric distribution rate request has been signaled for ~2027 (reported ~12.5% proposed). Supply portions adjust semi-annually (June 1 / December 1).
Cost Optimization Strategies
Because PECO C&I bills combine regulated distribution charges with separately-procured generation supply, the biggest savings levers are (1) competitive supply procurement and (2) demand/peak management given the per-kW distribution and PJM capacity charges.
Shop competitive generation supply
For: All GS, PD, HT and gas GC accounts
Generation is unbundled in PA. Procure supply via a licensed competitive supplier (PA Power Switch) instead of PECO default service to lock pricing and avoid semi-annual default-rate volatility.
Manage peak demand / improve load factor
For: Demand-metered GS, PD and HT customers
The $11.35/kW GS demand charge and the 40%-of-contract-demand billing floor above 500 kW make peak shaving and load-factor improvement directly bill-reducing. Stagger equipment startup and shift loads off coincident peaks.
Optimize PJM capacity (Class 3/4)
For: Large PD/HT customers (Procurement Class 3/4)
Large customers are billed on PJM's reliability pricing model based on Peak Load Contribution (PLC). Reducing usage during the ~5 PJM coincident-peak hours each summer lowers the following year's capacity tag.
Confirm correct voltage/rate classification
For: Large commercial/industrial sites near voltage thresholds
Verify the account is on the most economical schedule given service voltage and transformer ownership (GS vs PD vs HT thresholds). Taking primary/high-tension service and owning transformation can lower delivery costs for large loads.
