Move Power Across
Every Grid. We Handle the Tags.
Buying energy in PJM and delivering it to CAISO? Every handoff between balancing authorities requires a NERC e-tag. ennrgy.com manages the reservations, receipts, and compliance so your energy gets where it needs to go.
The Basics
What is e-tagging?
When electricity moves from one balancing authority to another, NERC requires an electronic tag (e-tag) to track the transaction end to end. The e-tag records where the power originates, every grid it passes through, and where it lands.
Think of it like a shipping manifest for electrons. Each handoff between ISOs or RTOs requires its own reservation, approval, and loss accounting. Miss a step and the energy doesn’t move.
Reservations
Before power can traverse a transmission path, you need a reservation at every point along the route. Each balancing authority approves or denies the request. We manage the full reservation workflow.
Path accounting
Every e-tag specifies the source, sink, and each intermediate balancing authority. The receipts along the way prove where the energy went and in what quantity. We track every megawatt across every handoff.
Loss tracking
Moving 1,500 MW from Pennsylvania to California might require purchasing 1,632 MW to account for transmission losses at each hop. We calculate and document the loss components so your settlements reconcile.
Why It Matters
NERC compliance is not optional.
NERC implemented the e-tag system in 1999, replacing fax and phone-based scheduling. Today, every interchange transaction in North America requires a properly formatted, approved e-tag. Violations carry federal penalties.
Managing e-tags in-house
- ×Staff must understand NERC tagging rules across every path and balancing authority
- ×Reservation timing is tight: miss a window and the energy sits
- ×Loss calculations vary by path and time of day
- ×One tagging error can delay or kill a transaction
- ×Audit trail documentation falls on your operations team

How It Works
From trade to tag in four steps
You execute a trade
You buy or sell energy that needs to move across balancing authority boundaries. You tell us the source, sink, volume, and schedule.
We build the path and reserve capacity
Our scheduling team maps the transmission path through each intermediate ISO or RTO, secures reservations at every handoff point, and calculates the loss components for each leg.
We create and submit the e-tag
The NERC-compliant e-tag is created with all required fields: source and sink balancing authorities, energy profiles, transmission service details, and curtailment priority. Every approval is tracked.
You get receipts and reconciliation
Complete documentation of every tag: where the energy went, how much was lost in transit, and the final delivered volume. Ready for settlements, audits, and your own records.
Who Uses This
If you move power across grids, you need e-tags.
E-tagging applies to any entity scheduling interchange transactions between balancing authorities. That includes:
Energy traders
Buying cheap power in one market and selling it in another is the business. The e-tag is the paperwork that makes the delivery possible. We handle it so you can focus on the spread.
Retail energy providers
REPs operating across multiple ISOs need compliant interchange scheduling for every cross-border transaction. Our team already works with 55+ suppliers across all 7 ISOs and RTOs.
Utilities and power marketers
Any market participant with interchange activity needs e-tags. Whether it’s a municipal utility buying capacity or a marketer moving blocks across regions, the compliance requirements are the same.
Full Coverage
We tag across every major ISO and RTO.
Your energy might cross three grids or five. We handle the tagging at every handoff, regardless of the path.
