Habersham Electric Membership Corporation (HEMC) Rate Selection Guide
Habersham EMC is a Northeast Georgia electric cooperative serving roughly 37,500 customers across six counties on 3,800+ miles of line. AMI smart meters were deployed territory-wide in 2016-2017, but the SEDC-based platform exposes only monthly usage through SmartHub — interval data, Green Button, EDI, and APIs are not customer-accessible. Third-party access runs through written authorization forms processed manually by Member Services.
Market Overview
HEMC operates as a non-profit member cooperative in Georgia's regulated market. The Georgia PSC does not mandate data-access standards for cooperatives as aggressively as some states do for IOUs, which is reflected in HEMC's limited programmatic access.

Current Rate Schedules
Habersham EMC (HEMC) serves northeast Georgia's Habersham, Rabun, Stephens, White, and Hall counties as a member-owned cooperative. All rates carry the Wholesale Power Cost Adjustment (WPCA, Schedule P-22), a monthly rider that passes through changes in purchased power costs and can be a charge, credit, or zero. Commercial accounts take Schedule GS-25 General Service — a blocked structure that combines volume tiers with hours-use-of-demand pricing — with companion schedules for all-electric (GSAE-25), time-of-use (GSTOU-25), load management (LMS-25), market-based service for large loads (MBS-22), and EV charging (CEV-25). Tariffs are filed with the Georgia PSC (Docket 31536).

Excess kVAR billed at $0.30; minimum charge $12.00/kW; WPCA applies. | 4.52-13.61¢/kWh by block + WPCA |
| Schedule GSTOU-25 — General Service Time-of-Use | commercial | Commercial accounts able to shift load off-peak | On-peak demand charge (~$13.40/kW in recent filings) plus non-coincident demand and off-peak energy pricing; rewards moving consumption out of peak windows.

Rate Recommendations by Use Case
Retail, office, or small commercial building
Standard GS-25 accounts with modest demand.
GS-25's hours-use structure means low-load-factor accounts pay the steep first blocks (13.61¢) while consumption beyond 600 hours-use prices at 4.52¢ — a 3x spread. Even small operations benefit from spreading usage and avoiding demand spikes that re-tier their energy.
- Three-phase service costs $28/month more in service charge — confirm it's needed
- Track the WPCA line monthly; it can swing bills independent of usage
- Watch power factor: HEMC bills excess kVAR at $0.30, and poor PF inflates billing demand
Poultry processing, manufacturing, or other high-load-factor operation
Continuous-operation facilities common in northeast Georgia's poultry and manufacturing corridor.
Round-the-clock operation pushes most kWh past 600 hours-use into the 4.52¢ block, producing a blended rate far below low-load-factor peers. The largest loads should evaluate market-based service (MBS-22) against blocked GS-25 pricing.
- Compute monthly hours-use (kWh ÷ billing demand) — above 600 is where GS-25 gets cheap
- Note the winter demand ratchet in billing demand determination — a single winter peak can set demand for months
- Install capacitor banks if power factor drops below ~97%; kVAR charges and demand inflation compound
School, church, or facility with shiftable or curtailable load
Institutions able to shift usage off-peak or accept load control.
TOU service concentrates cost into the on-peak demand charge (~$13.40/kW), so facilities that can pre-cool, schedule around peak windows, or accept utility load control of HVAC/water heating earn structural savings; SLMS-25 exists specifically for schools.
- Map your operating schedule against HEMC's on-peak windows before enrolling
- Pair TOU with automated controls — manual peak avoidance rarely holds up
- Ask Member Services to run a 12-month bill comparison on your actual interval data before switching
Fleet operator adding EV charging
Businesses installing Level 2 or DC fast charging in HEMC territory.
Commercial EV charging is spiky, low-load-factor load — exactly what GS-25's hours-use blocks penalize. The dedicated CEV-25 commercial EV schedule and managed overnight charging avoid demand-driven cost blowups.
- Meter chargers separately under CEV-25 rather than stacking them on the building's GS-25 account
- Schedule fleet charging overnight and stagger charger starts to cap coincident demand
- Confirm transformer capacity with HEMC early — upgrades drive timelines and costs
Cost Optimization Strategies
With monthly-only data, HEMC members optimize costs through structured bill tracking, requested usage exports, and direct rate-class review with Member Services.
Request historical usage exports
For: C&I members analyzing consumption
Member Services can produce up to ~14 months of retained usage data (CSV/PDF) on request — the only path to anything beyond portal monthly totals for trend analysis.
Maintain a SmartHub bill archive
For: All members
Download per-bill PDFs monthly and track usage trends across periods; the portal's month-over-month comparison flags anomalies worth investigating.
Verify rate schedule with the PSC filing
For: Commercial accounts
Cross-check the account's rate class against HEMC's Georgia PSC Docket 31536 tariff filings to confirm the lowest-cost applicable schedule.
Ask about Green Button enablement
For: Members needing granular data
SmartHub supports Green Button on peer cooperatives — if HEMC enables it, interval-grade exports become possible; periodically confirm with (706) 754-2114.
To implement these strategies, you need your 15-minute interval data. Learn how to download Habersham Electric Membership Corporation (HEMC) interval data →
Frequently Asked Questions
Can I get interval data from Habersham EMC?▾
Not through self-service. HEMC deployed AMI smart meters territory-wide in 2016-2017 (34,000+ meters via Smart Grid Solutions ProField), but SmartHub exposes monthly usage only. Up to ~14 months of retained meter data may be obtainable by calling Member Services at (706) 754-2114 — provide your account number, date range, and intended use, and expect CSV or PDF delivery in 5-10 business days.
Does HEMC support Green Button, EDI, or an API?▾
No confirmed support for any. Green Button download is unconfirmed (SmartHub supports it on peer cooperatives — ask HEMC directly), there is no EDI trading partner program, and no public API or developer portal. The SEDC backend supports MultiSpeak/ESPI internally but exposes nothing to third parties.
How does a third party get authorized to access HEMC member data?▾
Through a written customer release form. Request the authorization form from Member Services at (706) 754-2114, have the member sign it specifying the third party and data scope, and submit it to HEMC. After identity verification, HEMC delivers data (PDF bills or CSV usage) within 5-15 business days. Authorization typically runs 12 months and requires annual renewal.
What billing data is available in HEMC's SmartHub?▾
Multiple months of billing history with per-bill PDF downloads, bill amount and due dates, usage summaries and charge breakdowns, and monthly consumption graphs. Up to 14 months of usage history is indicated by SmartHub's standard capability. Paperless billing delivers notifications by email or text.
How can a platform programmatically access HEMC data?▾
Nectar provides API access to this utility's billing and interval data — see docs.nectarclimate.com. When scoping multi-site portfolios that include HEMC territory, plan on Nectar's integration, customer-provided exports, or HEMC's manual customer authorization process.
What does Nectar's roadmap support level mean for Habersham EMC?▾
HEMC is on Nectar's roadmap: automated ingestion is planned but not yet productized. Today, Nectar works with member-downloaded SmartHub bill PDFs, manually requested CSV usage exports, or data delivered under HEMC's third-party authorization process while integration options are evaluated.
