Current Rate Schedules
Baltimore Gas and Electric (BGE), an Exelon company, is the electric and gas distribution utility for central Maryland, regulated by the Maryland Public Service Commission (PSC). Maryland is restructured: BGE provides delivery (distribution) service while generation/supply comes from BGE's Standard Offer Service (SOS, market-priced) or a competitive retail supplier. Commercial electric delivery rates are set under BGE's multi-year rate plan (MYP, PSC Order No. 90948) with rates stepping up Jan 1, 2024 / 2025 / 2026. Larger commercial classes (Schedule GL and Schedules P/T) are demand-metered with per-kW delivery demand charges.

Rate Recommendations by Use Case
Multi-site commercial portfolio benchmarking
Aggregate monthly building usage across a Maryland portfolio for ENERGY STAR and BEPS compliance.
EUDS delivers building-level monthly data in ENERGY STAR-ready formats and supports Maryland BEPS, avoiding manual bill collection.
- Enroll buildings in EUDS early to backfill 3+ years of history
- Share building access with your benchmarking consultant
- Map every serving meter to the correct building
Demand charge reduction for large facilities
Use 15-minute interval data to manage coincident peak demand on large general service schedules.
Demand (kW) charges are a large share of delivery cost; interval data from CD Web pinpoints peaks to shave.
- Pull 867 HI interval data via a registered consultant with an LOA
- Target the few intervals that set monthly peak demand
- Consider load shifting or storage to clip peaks
Competitive supply procurement
Run supplier RFPs in Maryland's deregulated market using interval load data.
Supply is shoppable; an accurate interval load shape gets tighter supplier bids versus default SOS pricing.
- Provide 12 months of interval data to bidders
- Compare fixed vs. index products
- Watch for auto-rollover at contract end
Automated data integration for energy software
Feed BGE usage into an energy management platform via CD Web XML or Nectar.
BGE lacks a modern REST API; CD Web XML (LOA-based) or Nectar (docs.nectarclimate.com) are the integration paths.
- Batch CD Web requests within the 500-account daily HIU limit
- Standardize on ESPI XML where Green Button is available
- Maintain LOAs for each account
Historical Rate Trends
BGE distribution rates rose under its first multi-year rate plan (MYP, PSC Order No. 90948), with the PSC authorizing $408M of the $602M BGE requested in electric and gas distribution increases across 2024-2026, plus subsequent annual reconciling/MYP adjustments.
December 14, 2023
PSC Order No. 90948 approved BGE's first multi-year rate plan, authorizing ~$408M in electric and gas distribution increases through 2026 (vs. ~$602M requested), with rates effective Jan 1, 2024 / 2025 / 2026.
$408M authorized (of $602M requested) through 2026January 1, 2025
Year 2 of the MYP took effect: Schedule GL secondary delivery demand rose to $5.39/kW and delivery energy to $0.02279/kWh; Schedule G secondary delivery rose to $0.04819/kWh.
MYP Year-2 step-up (~3-4% delivery)January 1, 2026
Year 3 of the MYP took effect: Schedule GL secondary delivery demand $5.52/kW and energy $0.02346/kWh; Schedule G secondary delivery $0.04965/kWh; small residual electric (~+0.1 cents) and larger gas (~+4.2 cents) distribution increases.
MYP Year-3 step-upOverall trend: increasing
Next expected change: Final MYP step-up effective Jan 1, 2026 (electric distribution +~0.1 cents, gas +~4.2 cents on the residential metric), with a subsequent multi-year rate case expected to set 2026+ rates; the PSC has cut later BGE requests on affordability grounds.
Cost Optimization Strategies
BGE commercial customers save most by choosing the right rate class and voltage, managing peak demand on GL/P-T, and shopping supply against market-priced Standard Offer Service.
Manage peak demand on Schedule GL
For: Schedule GL, Schedules P & T
Schedule GL bills a per-kW delivery demand charge ($5.52/kW Secondary in 2026) plus generation/transmission demand on the peak period. Peak-shaving with batteries and limiting coincident demand reduces these per-kW charges.
Shop supply vs. Standard Offer Service
For: All commercial electric schedules
Generation/transmission is unbundled. Customers can take market-priced SOS or contract with a competitive retail supplier to hedge price and potentially lower the supply portion of the bill while BGE delivery charges stay fixed under the MYP.
Select the optimal rate class (G vs. GS vs. GL)
For: Schedule G, GS, GL
Below 60 kW, customers can compare Schedule G against Schedule GS (seasonal, lower customer charge $18.60 but different energy rate). At/above 60 kW, GL with its demand structure applies; verifying the lowest-cost class for the load profile avoids overpaying.
Evaluate primary/transmission service
For: Large GL, Schedules P & T
Schedule GL primary delivery rates ($4.99-$5.30/kW demand, ~$0.0212-$0.0225/kWh) are lower than secondary, and Schedules P/T are lower still. Large facilities able to own transformation can cut per-unit delivery costs.
Optimize gas usage under Schedule C declining blocks
For: Schedule C commercial/industrial gas
Schedule C's declining-block distribution structure lowers the marginal distribution rate at higher volumes; aligning large gas loads and evaluating competitive gas supply can reduce total gas cost.

Frequently Asked Questions
How do C&I customers get 15-minute interval data from BGE?▾
Authorized suppliers, aggregators, and consultants request 15-minute electric interval data (867 HI) through BGE's CD Web portal at https://secure.bge.com/cdweb/, using a signed customer Letter of Authorization. Up to 12 months of interval data is available and delivered as XML. BGE limits daily Hourly Interval Usage requests to 500 accounts per CD Web user per day.
Does BGE offer a public API for usage data?▾
No. BGE does not publish a modern REST API. Programmatic third-party access runs through the CD Web portal (XML, LOA-based) and, for suppliers, ANSI X12 EDI (electric) or XML transactions (gas). Customers can also export ESPI XML via Green Button Download My Data, and Nectar provides API access to this utility's billing and interval data — see docs.nectarclimate.com.
Can I shop for a competitive electricity or gas supplier?▾
Yes. Maryland's electricity market is deregulated and gas supply is competitive. BGE remains the regulated distributor and Standard Offer Service provider, while licensed suppliers compete for supply. Suppliers enroll customers via 814E EDI transactions; enrollment takes effect three business days after processing, with a maximum of two enrollments per bill cycle.
How do I benchmark buildings for Maryland BEPS compliance?▾
Use the Exelon Energy Usage Data System (EUDS) at https://www.exelonenergyusagedata.com/. It provides monthly aggregate building usage that integrates with ENERGY STAR Portfolio Manager and supports Maryland Building Energy Performance Standards. Building owners can share access with authorized consultants and download data as CSV, XLSX, or Green Button XML.
What does Nectar's roadmap support level mean for BGE?▾
BGE is on Nectar's roadmap, meaning automated ingestion is planned but not yet fully productized. Today, Nectar can work with BGE data via CD Web XML exports (with customer LOA), EUDS benchmarking files, or other interim paths while native integration is built out.
