OASIS Transmission Monitoring
OASIS Transmission
Intelligence
TransANCHOR monitors transmission capacity data across 21 OASIS providers on market days and emails you a daily digest with AI summaries and criticality rankings — without logging into each portal.
Background
What Is OASIS?
OASIS — the Open Access Same-time Information System — is the mandatory, standardized data disclosure platform that all public utilities with interstate transmission facilities must maintain under FERC Order 889. It was designed to level the playing field: transmission owners must post the same capacity, availability, and pricing information to all potential customers simultaneously, preventing any affiliate from gaining an informational advantage.
OASIS data governs who can move power where, at what price, and under what conditions. When available transfer capability drops, when a curtailment is posted, or when a new transmission service request appears — those postings have direct operational and commercial significance. For anyone involved in transmission planning, power marketing, renewable interconnection, or grid operations, OASIS is a primary source of ground truth.
The problem: there is no single OASIS. Each transmission provider — investor-owned utilities, RTOs, ISOs, and cooperatives — operates its own OASIS node with its own portal, its own data format, and its own update cadence. There are dozens of them. No one is watching all of them at once. Until now.
OASIS by the Numbers
Why a single portal can't cover the grid
What you'll see
Your daily OASIS digest
Each market day, eligible changes roll into one email: a summary line, provider context, subject and timestamp, a criticality badge (for example LOW / MEDIUM / HIGH), and a short AI summary — so you can triage fast.
OASIS Monitor digest emails are included with your account. Pick your providers in Monitor Settings after you sign in.

Coverage
What TransANCHOR Monitors
Across selected providers. Automatically. Surfaced in your daily digest when something changes.
Available Transfer Capability (ATC)
The transmission capacity currently available for sale. ATC changes signal congestion, curtailments, or capacity releases — all commercially significant.
Total Transfer Capability (TTC)
The maximum power flow between areas that can be accommodated reliably. TTC postings set the ceiling for all transmission transactions.
Transmission Curtailments
Posted when granted transmission service must be reduced due to reliability concerns or congestion. Curtailment notices have immediate operational impact.
New Transmission Service Requests
Applications from market participants seeking to move power over a provider's system. Surge in requests can signal market activity or congestion development.
Tariff Rate Postings
Point-to-point and network integration service rates, ancillary service charges, and transmission rate updates posted to each provider's OASIS.
Data Change Detection
TransANCHOR tracks the state of each provider's OASIS and alerts when values change — not just when new filings appear, but when underlying conditions shift.
The Problem
Why Manual OASIS Monitoring Doesn't Work
✗ The Manual Approach
- — Log into each provider's OASIS portal individually — there's no unified view
- — Each portal has a different interface, navigation, and data format
- — ATC data refreshes throughout the day — a snapshot at 9am is stale by noon
- — No notifications when curtailments are posted or ATC drops significantly
- — Miss activity on providers outside your usual coverage region
- — Manually reconcile data across providers with no common format
✓ The TransANCHOR Way
- ✓ TransANCHOR monitors all providers automatically — no portal logins required
- ✓ Normalizes data across different OASIS implementations into a consistent format
- ✓ Detects changes on each monitoring run and includes them in your next daily digest email
- ✓ Delivers a structured email summary of OASIS activity for the period
- ✓ Full coverage across providers — not just the ones you happen to check
- ✓ One digest, one format — every market day
Audience
Who Needs OASIS Monitoring
Transmission Customers
Companies purchasing point-to-point or network integration transmission service need to know when capacity is available, curtailed, or changing — before it affects scheduled power flows.
Renewable Developers
Wind and solar developers depend on ATC availability for interconnection studies, power purchase delivery commitments, and capacity planning along specific corridors.
Power Marketers & Traders
OASIS data is commercially sensitive. ATC changes signal congestion developing in real time, allowing market participants to adjust positions and schedules before flows are curtailed.
Grid Planners & Engineers
Transmission planning teams need to track TTC and ATC trends across the interconnection to identify congestion patterns, bottlenecks, and infrastructure investment priorities.
Energy Lawyers & Regulatory Staff
OASIS data is entered as evidence in transmission disputes, rate cases, and interconnection proceedings. Having reliable historical snapshots and alerts matters.
ISOs, RTOs & Utilities
Grid operators and transmission owners that need cross-system visibility on what their counterparts are posting — particularly in shared seams or bilateral transaction corridors.
OASIS Monitoring
Real-time alerts on transmission capacity changes across all providers.
