Interval Data & Smart Meters

CORE has deployed AMI smart meters that capture consumption at 15-minute intervals across its territory. Members access hourly and daily data through SmartHub's My Usage / Usage Explorer; 15-minute granularity is reachable only via an unofficial reverse-engineered SmartHub API.

Meter Technology
Advanced Metering Infrastructure (AMI) on the NISC platform with remote reads, power-quality metrics, and peak-demand tracking.
Electric Granularity
15-minute interval reads internally; hourly and daily data exposed via SmartHub Usage Explorer; 15-minute data only via an undocumented reverse-engineered API.
Gas Granularity
Not applicable (electric-only cooperative).

How to Download CORE Electric Cooperative Interval Data via Green Button

  1. 01Green Button (CMD/DMD) is not explicitly enabled by CORE, although NISC supports Green Button standards.
  2. 02Use SmartHub My Usage > Usage Explorer to view hourly/daily data; official CSV export is limited to hourly since January 2024.
  3. 03For 15-minute data, the community electric-usage-downloader tool can pull from the SmartHub backend (unsupported, at your own risk).

Interval data is essential for rate comparison and TOU analysis.

Green Button Access

Download My Data

CORE does not explicitly enable Green Button Download My Data, though its NISC platform supports the standard. Members export hourly CSV via SmartHub Usage Explorer instead.

Available To
Not explicitly enabled

Connect My Data

CORE does not offer Green Button Connect My Data or an OAuth 2.0 third-party authorization flow. Automated monthly data sharing for benchmarking is delivered via ENERGY STAR Portfolio Manager instead.

API Standard
None (NISC supports ESPI but it is not customer-enabled)
Available To
Not available

04

Third-Party API Access

CORE does not offer an official developer API, OAuth flow, or developer portal. Third parties access data through customer-authorized SmartHub logins, the Building Benchmarking program (Portfolio Manager), or direct data requests to Business Development. A reverse-engineered SmartHub API exists for 15-minute data but is unsupported and may break at any time.

Program
No official API (SmartHub portal + benchmarking)
Auth Method
Account Access Authorization Form (customer consent); no OAuth.
Rate Limits
Not published; reverse-engineered API may trigger rate limiting.
Interval Latency
Near-real-time; data updated daily.

How to Register as a CORE Electric Cooperative API Vendor

  1. 01Obtain a signed Account Access Authorization Form from the customer.
  2. 02Create a SmartHub account linked to the customer's account, or coordinate Portfolio Manager access.
  3. 03For bulk data, contact CORE Business Development (rosborn@core.coop) with account numbers and specifications.

05

EDI (Electronic Data Interchange)

How to Enroll in CORE Electric Cooperative EDI

  1. 01CORE does not publish an EDI trading-partner program; it may have internal NISC EDI for billing (810), usage (867), and enrollment (814) not exposed to third parties.
  2. 02To inquire, contact CORE Business Development (rosborn@core.coop, 800-332-9540) about EDI availability, ANSI X12 version support, and VAN requirements.
  3. 03If EDI is unavailable, CORE may offer custom API or data-export solutions for strategic partners.

06

Rate Schedules & Tariff Analysis

CORE's C&I schedules layer a fixed service charge, demand charges (basic and, in TOU/coincident-peak variants, on-peak or coincident-peak demand), and energy charges. Energy rates decline and demand rates rise as load scales from Small General Service through Industrial, High Load Factor, and Coincident Peak schedules, rewarding high load factor and coincident-peak management.

CORE Electric Cooperative Rate Schedule List

ScheduleApplicability
Large Power Service (LPS)Larger commercial accounts.
Industrial Service (S / SP)Industrial accounts (secondary/primary).
High Load Factor (HLF / HLFP)Steady high-load-factor industrial loads.
Coincident Peak (CPD / CPS / CPT)Largest substation/transmission loads.

CORE Electric Cooperative Rate Features & TOU Details

  • Fixed monthly service charge scales with schedule ($27 SG1 to $1,650 CPT).
  • Demand charges dominate larger schedules ($15.09/kW LPS to $26.81/kW HLF).
  • Energy rates decline with scale ($0.073/kWh SG1 down to ~$0.042/kWh CPT).
  • Time-of-Use variants available for most schedules with on-peak (4-8 p.m.) pricing.
  • Coincident Peak schedules bill demand on the system coincident peak, rewarding off-peak operation.
  • Board-approved average 6.7% increase effective with January 2026 bills.

08

Limitations & Considerations

  • No official developer API; programmatic 15-minute access relies on an unsupported reverse-engineered SmartHub API.
  • No publicly documented EDI trading-partner program.
  • Official CSV export limited to hourly since January 2024 (15-minute CSV was previously available).
  • Green Button (CMD/DMD) is not customer-enabled despite NISC platform support.
  • Third-party access requires a per-account Account Access Authorization Form; bulk requests route through Business Development and may incur fees.

CORE Electric Cooperative Data Access FAQ

How do CORE commercial and industrial members access interval usage data?

Through SmartHub's My Usage > Usage Explorer, which shows hourly and daily consumption with up to 24+ months of history and hourly CSV export. For 15-minute data, only an unofficial reverse-engineered API is available. For bulk exports across multiple accounts, contact CORE Business Development.

Which rate schedule applies to a large commercial or industrial CORE account?

CORE offers Large Power Service (LPS) and Industrial (S/SP) schedules, plus High Load Factor (HLF/HLFP) and Coincident Peak (CPD/CPS/CPT) schedules for the largest loads. As of the May 1, 2025 rates, LPS carries a $135/mo service charge, $15.09/kW demand, and $0.06679/kWh energy; Industrial (S) is $270/mo, $21.45/kW, and $0.05658/kWh. Time-of-Use variants exist for most schedules.

Can a third party access CORE data on a customer's behalf?

Yes, via a signed Account Access Authorization Form that lets the third party use SmartHub for the customer's account, or via the Building Benchmarking program (Portfolio Manager) for covered buildings. CORE has no public API or OAuth flow; bulk needs route through Business Development.

Does CORE support Green Button or EDI?

No. CORE has not enabled Green Button (CMD/DMD) for customers, though its NISC platform supports the standard. There is no publicly documented EDI trading-partner program; CORE may have internal NISC EDI not exposed to third parties. Inquire with Business Development about custom integration options.

How are CORE C&I rates set and how often do they change?

CORE is a member-owned cooperative whose elected board approves rate changes (Colorado cooperatives are largely exempt from PUC rate regulation). The most recent changes took effect May 1, 2025, and the board approved an average 6.7% increase effective with January 2026 bills across residential, commercial, and industrial classes.
