Jones-Onslow EMC Rate Schedule Comparison
| Schedule | Type | Rate | Best For |
|---|---|---|---|
| Small Commercial / General Service | commercial | Basic charge + per-kWh + WPCA, no demand charge | Small offices and retail below demand threshold |
| Commercial Demand Service | commercial | Basic + per-kW (15-min peak) + per-kWh + WPCA | Mid-size commercial with notable peaks |
| Large Power / Industrial | industrial | Basic + per-kW demand + per-kWh + WPCA | Large commercial and industrial loads |
Market Overview
Regulated, vertically delivered cooperative service. JOEMC buys bulk power through NCEMC and delivers it; members cannot choose a competitive supplier. The cooperative's board sets retail rates.

Current Rate Schedules
JOEMC does not publish exact per-kWh energy or per-kW demand tariff values on its public site; the figures below describe the verified rate STRUCTURE and the few verified amounts (residential basic charge $35.00; commercial demand metered over a 15-minute interval). The illustrative $5/kW and $0.05/kWh figures in JOEMC's own demand explainer are examples, not actual tariff rates. Confirm exact C&I rates with JOEMC Member Services at (910) 353-1940.

Rate Recommendations by Use Case
Small commercial (office, retail, no demand meter)
Energy-only general service with a fixed monthly charge.
Below the demand-metering threshold, the bill is a monthly basic charge plus per-kWh energy and WPCA, with no demand charge to manage. Confirm the exact per-kWh rate with Member Services.
- Use the portal's daily usage view and alerts to track consumption
- Enable paperless and AutoDraft billing
- Ask Member Services whether your load qualifies for demand metering as you grow
Mid-size commercial (demand-metered)
Demand service billed on the 15-minute peak.
JOEMC bills the highest 15-minute average kW each month, so flattening peaks directly lowers the demand charge. The exact $/kW is not published; request it from Member Services for ROI modeling.
- Stagger equipment startups to avoid coincident peaks
- Know your monthly meter-read date and avoid testing large equipment just before it
- Run infrequently-used equipment while other loads are off
Large power / industrial
Large demand-metered service.
Demand and WPCA dominate large-load bills. Because there is no retail choice, optimization focuses on demand management and efficiency rather than supplier shopping.
- Use QuestLine (free technical assistance) for efficiency studies
- Request interval/demand data from Member Services for peak analysis
- Evaluate on-site generation/storage for peak shaving
Historical Rate Trends
JOEMC had not increased its kWh rate in more than 10 years (since 2013) before the April 1, 2026 adjustment, having absorbed rising costs internally. The increase was driven by approximately $7 million in higher wholesale power costs from NCEMC. Ongoing WPCA adjustments pass through wholesale power cost changes.
April 1, 2026
First kWh rate increase in more than 10 years, driven by approximately $7 million in higher NCEMC wholesale power costs.
not disclosedJanuary 1, 2013
Approximate last prior kWh rate level; JOEMC held the kWh rate flat from this period until 2026.
n/aOverall trend: Historically very stable kWh rate (flat for a decade), with a 2026 increase reflecting industry-wide wholesale power cost pressure; WPCA fluctuates with NCEMC costs.
Next expected change: No specific next change announced; WPCA adjusts periodically with wholesale power costs
Cost Optimization Strategies
Because North Carolina has no retail choice, JOEMC C&I cost optimization centers on demand management, efficiency, and using available data tools rather than supplier shopping.
Peak demand management
For: Demand-metered commercial and industrial accounts
Stagger equipment operation and shift flexible loads to lower the highest 15-minute average kW that sets the monthly demand charge.
Meter-read timing for infrequent equipment
For: Demand-metered accounts
Operate infrequently-used high-draw equipment after the monthly meter read to avoid setting a high demand peak for the whole billing period.
Efficiency rebates and QuestLine
For: All business accounts
Use commercial lighting retrofit rebates and the free QuestLine technical assistance service to cut both energy and demand.
Usage monitoring and alerts
For: All accounts
Use the portal's daily usage data and threshold alerts to catch consumption anomalies early.
To implement these strategies, you need your 15-minute interval data. Learn how to download Jones-Onslow EMC interval data →
Frequently Asked Questions
How does a C&I customer get usage data from JOEMC?▾
Through the Meridian billing portal or mobile app, which show daily usage summaries and 12 months of billing/payment history. There is no Green Button export or API. For raw or automated data, contact Member Services at (910) 353-1940 to arrange a manual CSV export or portal credential delegation with customer authorization.
Does JOEMC offer interval (15-minute) data or an API?▾
No. JOEMC's Landis+Gyr Gridstream AMI supports interval metering at the grid level, but the consumer-facing product is limited to daily summaries. No sub-hourly interval data, Green Button, or public API is documented.
How are commercial demand charges calculated?▾
For most commercial customers, JOEMC monitors demand over a 15-minute period and bills the highest 15-minute average (in kW) recorded that month. Demand is reset to zero after each monthly read. Demand charges recover the generation and distribution capacity needed to meet peak load.
Can my facility shop for a competitive electricity supplier?▾
No. North Carolina is a regulated electricity market with no retail choice for cooperative members. JOEMC purchases wholesale power through NCEMC and is the sole provider of both energy and delivery in its territory.
When did JOEMC last change its rates?▾
A rate adjustment took effect April 1, 2026 — JOEMC's first kWh rate increase in more than 10 years, driven by roughly $7 million in higher wholesale power costs from NCEMC. The residential basic monthly charge is $35.00.
