Interval Data & Smart Meters

DEC has deployed Advanced Metering Infrastructure (AMI) across its territory. Bills reference demand 'averaged in any 15 minute period,' confirming 15-minute interval collection. Members view usage graphs in SmartHub and the DEC Connect app. As of January 2024, CSV export of 15-minute data was restricted; standard export provides hourly granularity, with 15-minute data accessible via Green Button download.

Meter Technology
Advanced Metering Infrastructure (AMI) smart meters across the service territory.
Electric Granularity
15-minute interval data collected (demand); hourly typically available via standard SmartHub export, 15-minute via Green Button download.
Gas Granularity
Not applicable (electric-only cooperative).

Rate Schedules & Tariff Analysis

DEC commercial pricing separates a distribution delivery component (customer, distribution energy, and demand charges) from an energy supply component (transmission, ancillary, and supply energy/demand rates), with a Power Cost Adjustment of $0.03069/kWh layered on all kWh. Small commercial members (under 50 kW) on General Service pay energy-only rates with no demand charge. At 50 kW and above, Large Commercial introduces a substantial demand charge (~$8.95/kW combining distribution, transmission, ancillary, and supply demand) billed on the maximum 15-minute average kW, making peak management the primary cost lever. Primary-voltage service (LC-P) trades a $110 customer charge for materially lower per-kWh rates.

Delaware Electric Cooperative Rate Schedule List

Delaware Electric Cooperative Data Access FAQ

How can a commercial or industrial member access 15-minute interval data from DEC?

C&I members can view usage in SmartHub and download up to 14 months of Green Button ESPI XML (which includes 15-minute granularity) from the My Usage section. Standard CSV export provides hourly data; the 15-minute CSV export was restricted as of January 2024. For automated feeds, contact Member Services at 855-332-9090.

Does DEC offer an API or Green Button Connect My Data for third-party energy managers?

DEC does not publish a developer API, and Green Button Connect My Data (automated OAuth access) is not confirmed as enabled. The supported path for third parties is member-initiated Green Button downloads shared with the provider, or a Letter of Authorization submitted to DEC. Confirm Connect My Data availability directly with DEC.

How are demand charges calculated for DEC commercial accounts?

For Large Commercial (Schedule LC, 50 kW or more), billing demand is the maximum 15-minute average kW during the month. Demand-related charges combine a distribution demand rate ($2.55/kW), transmission demand ($0.85/kW), ancillary demand ($0.08/kW), and a supply demand rate ($5.47/kW). A power factor below 90% increases billing demand by 1% for each full percent below 90%.

What is the Power Cost Adjustment (PCA) on DEC bills?

The PCA is a per-kWh charge that passes through the cost of wholesale power above the base energy rates in each tariff schedule. As of the current approved rate sheet, the PCA is $0.03069 per kWh and applies to all rate classes. It fluctuates with wholesale power costs.

Can a third party get data without sharing member login credentials?

Yes. The recommended approach is to have the member download their Green Button file from SmartHub and share it, or submit a signed Letter of Authorization to DEC Member Services. Credential sharing and screen-scraping are not recommended and may violate the platform terms of service.
