Wake EMC provides comprehensive online billing access through its SmartHub self-service portal (which replaced the legacy eBill system). All members can view current and historical bills, payment history, and usage at no charge.

Interval Data & Smart Meters

Wake EMC deployed Sensus FlexNet AMI across its entire territory beginning in 2012. Members view daily and hourly consumption in the SmartHub My Usage tab, with appliance-level disaggregation added in 2022. Raw 15-minute interval data is not directly exposed in the portal but is available via Green Button XML download.

Meter Technology
Sensus FlexNet AMI (managed by Sensus/Xylem); 56,000+ smart meters with 15-minute integrated demand, hourly kWh, and two-way communication.
Electric Granularity
Hourly kWh viewable in SmartHub; daily totals for 12+ months; 15-minute interval data available through Green Button XML export.
Gas Granularity
Not applicable (electric-only cooperative).

How to Download Wake Electric Membership Corporation Interval Data via Green Button

Green Button Access

Download My Data

Wake EMC was the first NC utility to offer Green Button (Sept 2013). Members download a zipped ESPI/XML file from SmartHub containing up to 13 months of interval and billing data. Downloads are free with no documented frequency limit.

Formats
Green Button XML (ESPI / NAESB REQ.21), ZIP archive
Available To
All members (residential and commercial)

Connect My Data

Wake EMC does not operate a Green Button Connect My Data (CMD) service. There is no OAuth-based, token-authorized API for automated third-party interval data delivery; all sharing is manual file transfer by the member.

Third-Party API Access

Wake EMC does not offer a public developer portal, REST API, or ESPI Connect My Data service. Its internal data infrastructure (Sensus RNI, Verdeeco analytics) is not exposed to third parties. Custom integrations may be requested directly but would likely be evaluated case-by-case at the requester's cost.

How to Register as a Wake Electric Membership Corporation API Vendor

  1. 01Contact Wake EMC at information@wemc.com or 919-863-6300 (Attn: VP Engineering & Operations).
  2. 02Describe the integration use case, volume, and data needed.
  3. 03Expect a case-by-case evaluation; cost would be borne by the requester. Default recommendation is member-mediated Green Button file sharing.

05

EDI (Electronic Data Interchange)

How to Enroll in Wake Electric Membership Corporation EDI

  1. 01No EDI program exists. To inquire, contact information@wemc.com or 919-863-6300.
  2. 02Specify your role (retailer, aggregator, CSP) and the transaction sets needed.
  3. 03Likely outcome: a small cooperative will not have EDI infrastructure and will recommend Green Button file sharing instead.

Rate Schedules & Tariff Analysis

Wake EMC C&I bills are demand-driven once usage exceeds 50 kW. The LGS schedule blends a modest first-50-kW demand block ($1.65/kW) with a higher over-50-kW block ($4.95/kW) and a declining-block energy charge (11.34 down to 6.98 cents/kWh). TOU and coincident-peak variants trade higher posted demand rates for the chance to cut billed demand by shifting or curtailing load. A 95% power-factor threshold applies to demand billing on accounts of 50 kW or more.

Wake Electric Membership Corporation Rate Schedule List

ScheduleApplicability
Small General Service (SGS)Non-residential, demand 50 kW or less
Large General Service (LGS)Non-residential, demand over 50 kW
Large General TOU (LGS-TOU)Above 50 kW, voluntary time-of-use
Large General Coincident Peak (LGS-CP)Above 50 kW with 50+ kW curtailment capability

Wake Electric Membership Corporation Rate Features & TOU Details

  • Demand charges dominate the bill above 50 kW
  • Declining-block energy pricing rewards higher monthly consumption
  • Optional TOU and coincident-peak schedules reward load flexibility
  • Power-factor penalty below 95% on accounts 50 kW and above
  • 15-minute interval demand metering across all accounts

Other Data Access Programs

Net Metering / Renewable Generation Rider

Wake EMC supports on-site renewable generation interconnected in parallel, with net energy billing and credits (e.g., 4.86 cents/kWh energy credit on the standard NRS rider) and standby provisions for larger generators.

  1. 01Submit an interconnection application with system specs
  2. 02Execute the interconnection agreement (safety and metering requirements apply)
  3. 03Generation is netted and credited per the applicable rider

Load Management / Coincident Peak Program

Wake EMC operates a load-management system; LGS-CP members curtail load on the cooperative's signal during anticipated wholesale-supplier peaks to reduce billed coincident demand.

  1. 01Demonstrate ability to shed at least 50 kW on signal
  2. 02Enroll in LGS-CP
  3. 03Respond to load-control / exposure-period signals to lower coincident-peak demand

08

Limitations & Considerations

  • No Green Button Connect My Data (CMD) or OAuth-based automated third-party access.
  • No public developer portal, REST API, or ESPI live API.
  • No EDI infrastructure (no 814/820/867/810 transactions).
  • No formal Share My Data or registered aggregator program; all third-party sharing is member-mediated.
  • Green Button history limited to 13 months; longer historical exports not documented.
  • Bill/usage CSV export from SmartHub is not explicitly documented (Green Button XML is the structured export path).

Wake Electric Membership Corporation Data Access FAQ

How does a commercial customer get interval (15-minute) data from Wake EMC?

Through SmartHub's Green Button download. Daily and hourly usage is shown directly in the My Usage tab, while raw 15-minute interval data is delivered in the ESPI/XML file you export via Green Button (13 months of history). There is no API or automated feed.

Can an energy consultant or aggregator pull our usage data automatically?

No. Wake EMC does not offer Green Button Connect My Data, a developer API, or EDI. Consultants receive data only when the member downloads Green Button XML or bill exports and shares the files directly. Custom arrangements can be requested from the cooperative but are evaluated case-by-case.

Which rate schedule applies to a commercial account over 50 kW?

Large General Service (LGS). It carries a $110 monthly facilities charge, tiered demand ($1.65/kW for the first 50 kW and $4.95/kW above 50 kW), and declining-block energy (11.34, 7.50, and 6.98 cents/kWh). Voluntary LGS-TOU and LGS-CP variants are available for flexible loads.

Does Wake EMC charge a power-factor penalty?

Yes. On accounts of 50 kW or more, if measured power factor is below 95%, billed demand is the metered demand multiplied by 95% divided by the measured power factor. Maintaining PF at or above 95% avoids this adjustment.

How can a C&I customer lower demand charges?

Use AMI/Green Button data to flatten monthly peaks, consider TOU schedules to shift load off on-peak windows, qualify for LGS-CP curtailment to be billed mostly on the lower noncoincident demand rate, and correct power factor to at least 95%.

Can our commercial members shop for a different electricity supplier?

No. North Carolina is a regulated market with no retail choice for cooperative members. Wake EMC provides bundled distribution and supply; rates are set by its board and reviewed by the NC Utilities Commission under Docket EC 47.
