See the Chesapeake Utilities Corporation Rate Schedules & Tariff Guide →Interval Data & Smart Meters
Chesapeake Utilities does not offer granular 15- or 30-minute interval data. Meters are read monthly for most customers; large Sales Service customers with annual consumption of 100,000+ units can receive remote telemetry devices, and tariff-defined CI Daily Read Pool customers receive daily reads. GS-3 customers exceeding 100,000 therms/year must have electronic metering installed at customer expense.

Rate Schedules & Tariff Analysis
Delaware Division non-residential rates use size-tiered schedules (GS-1/2/3) with declining-block delivery charges, so larger consumption pushes effective delivery cost per therm down sharply — tail-block rates run $0.08–$0.12/therm versus $0.24–$0.58 in the first block. The GS-HLFS schedule offers the lowest flat delivery rate ($0.10210/therm) for flat-load customers, and Transportation Service lets C&I customers shop the commodity while paying the same delivery blocks.
Chesapeake Utilities Corporation Rate Schedule List
| Schedule | Applicability |
|---|---|
| GS-1 General Service | Under 4,143 therms/year |
| GS-2 General Service | 4,143–15,535 therms/year |
| GS-3 General Service | 15,535+ therms/year |
| GS-HLFS High Load Factor | GS-2/3-eligible flat-load customers, winter under 35% of annual |
| GTS-1/2/3 Transportation | Non-residential customers with third-party gas supply |

Chesapeake Utilities Corporation Data Access FAQ
How can our energy management platform get usage data for commercial Chesapeake Utilities accounts?▾
There is no Green Button, API, or EDI channel. The supported routes are (1) the customer downloading PDF bills from MiPortal and sharing them, (2) enrolling as a tariff-defined Pool Manager with letters of authorization to receive monthly usage for all authorized accounts, or (3) submitting authorized data requests through Customer Care at 800.427.2883, which can take up to 90 days for BEPS-style requests.
Does Chesapeake Utilities provide interval (15-minute) gas data?▾
No. Most meters are read monthly. Large Sales Service customers (≥100,000 units/year) get remote telemetry with daily reads, and GS-3 customers above 100,000 therms/year must install electronic metering — but only daily/monthly aggregates are made available, with no third-party interval feed.
Can our business buy gas from a third-party supplier instead of Chesapeake?▾
Yes. Any non-residential customer can take General Transportation Service (GTS-1/2/3), buying gas through an authorized Pool Manager while Chesapeake delivers it at the regulated tariff blocks plus retainage. Compare supplier offers against the utility's GSR commodity rate — which rose about 18.6% in November 2025 — and note that leaving sales service may trigger a future transition charge.
Which rate schedule should our facility be on?▾
Schedules are tiered by annual consumption: GS-1 under 4,143 therms/year, GS-2 from 4,143 to 15,535, and GS-3 above 15,535. Flat-load customers with January–March usage under 35% of annual can qualify for GS-HLFS at a flat $0.10210/therm delivery rate. Chesapeake reviews assignments periodically, but verifying your own usage against the breakpoints avoids overpaying between reviews.
How do we get 5 years of usage history for ENERGY STAR or BEPS benchmarking?▾
For buildings of 35,000+ square feet, submit a BEPS data request at chpkgas.com/beps-reporting/ with an attestation of authorization. Chesapeake compiles up to five years of monthly gas usage and emails it within up to 90 days. Smaller buildings should request history through Customer Care at 800.427.2883 with written customer authorization.
What changed in Chesapeake's Delaware rates recently?▾
Base delivery rates were reset effective October 15, 2025 under PSC Order No. 10851 (Docket No. 24-0906). Separately, the annual GSR commodity filing raised typical bills about 18.6% (~$16.51/month) effective November 1, 2025, and an energy efficiency rider change is pending in Docket No. 26-0448 for May 1, 2026.
