Rate Schedules & Tariff Analysis
Choptank's C&I bills split a regulated delivery component (consumer charge, energy delivery $/kWh, demand $/kW) from a supply component (Standard Offer Service generation + transmission, or a competitive supplier). Demand-metered schedules bill the maximum 15-minute kW, so peak management and supplier shopping are the two main cost levers.
Choptank Electric Cooperative, Inc. Rate Schedule List
| Schedule | Applicability |
|---|---|
| Schedule C-D — Commercial Demand Service | Commercial single-phase ≤ 50 KVA (new members) |
| Schedule S — General Service Small | 3-phase or > 50 kW demand |
| Schedule M — General Service Medium | 3-phase or > 100 kW demand |
| Schedule GT — General Power TOU | > 50 kW demand, time-of-use |
| Schedule P / PT — Primary Service | Primary-voltage service |

Choptank Electric Cooperative, Inc. Data Access FAQ
How can a C&I member get 15-minute interval data from Choptank Electric?▾
Use Green Button Download My Data in SmartHub: log in, open My Usage / Usage Management, click Green Button Download My Data, choose a date range (up to 14 months), and download the ESPI XML ZIP. SmartHub's Usage Explorer also shows hourly/daily usage interactively. A reverse-engineered NISC SmartHub API can pull the same 15-minute data programmatically, but it is unofficial and unsupported.
Can my energy consultant access Choptank data directly?▾
There is no Green Button Connect My Data or official third-party API, so access is customer-mediated. The member downloads Green Button XML or bill PDFs from SmartHub and shares them with the consultant, who parses the ESPI data. For custom needs, email rates@choptankelectric.coop with written authorization.
Which rate schedule applies to a commercial or industrial facility?▾
Single-phase commercial loads of 50 KVA and less take Schedule C / C-D (new members go on C-D, which adds a demand charge). Three-phase or loads over 50 kW take General Service - Small (Schedule S); loads at or above 100 kW move to General Service - Medium (Schedule M). Time-of-use (GT) and Primary service (P, PT) schedules are available for larger or primary-voltage loads.
Can a C&I member shop for a competitive electricity supplier?▾
Yes. Maryland has retail supply choice. Through Choptank's Customer Choice program a member can buy generation/transmission supply from a competitive retail supplier while Choptank continues to deliver power and bill the regulated delivery charges. Members who do not shop receive Standard Offer Service (SOS) from the cooperative.
What drives demand charges on Choptank's C&I schedules?▾
Demand-metered schedules (C-D, S, M, GT, P) bill the maximum kilowatt demand over any 15 consecutive minutes during the month. On Schedule S, for example, the distribution demand charge is $4.20/kW plus an SOS transmission demand charge of $2.85/kW. Reducing the monthly 15-minute peak directly lowers these charges.
