Wholesale markets
Real-time energy, ancillary services, and settlement-grade decision records across ISOs and RTOs.
The call“Bid the block into day-ahead, or hold for real-time?”
POWERED BY REX DecisionOS
Energy does not have an information problem.
It has a decision problem.
A Decision Operating System for energy markets that turns forecasts, market signals, and operating constraints into defensible actions, designed to increase margin, reduce imbalance exposure, and improve the return on every MWh.
Everyone else stops short. We finish the call.

capability delivered · partial or human-in-loop · not in scope
You measure everything. Nothing you own decides.
Weather. Load. Generation. Markets. Transmission. Your forecasts get better every year, your dashboards multiply, and AI predicts more than it ever has. And still, every dollar you make or lose comes down to one moment.
Somebody has to make the call.
Dispatch.
Bid.
Buy.
Sell.
Curtail.
Ramp.
Charge.
Hold.
Wait.
Information reduces uncertainty. Information does not make the decision. It informs the people who do. And conditions do not stand still. The weather moves. The market moves. The grid moves. Yesterday’s best decision becomes today’s expensive mistake.
The insight
What if decision-making itself became software?
Not another dashboard. Not another prediction engine. Not another AI assistant. A Decision Operating System, built for the moment when the information is in and a call still has to be made.

It thinks before it moves. It decides better.
Every decision lives inside uncertainty. Several futures are possible: some likely, some dangerous, some expensive. When new evidence arrives, most systems just move. REX DecisionOS asks a harder question first.
01 · Credibility
What deserves authority?
Is the forecast credible? Has the signal drifted? Does it agree with what the system already knows, or is it noise? Every input earns its influence before it can change a call.
02 · Competing futures
Keep the alternatives alive.
Which futures did we not choose? Are they still on the table if the weather turns? Most optimizers collapse uncertainty into one expected future. We keep the alternatives priced and commit only when the call is defensible.
03 · Cost of being wrong
Wrong has a price tag.
How wrong could this call be? And how expensive would that wrong be? Being wrong is measured, not absorbed. The engine holds when signals are ambiguous and commits decisively when evidence lines up.
Dashboards inform. REX/Edge dispatches.
Sense
Read the state without editorializing.
Telemetry, market signals, upstream forecasts, all ingested as evidence, not as ground truth. Timestamps preserved. Provenance retained. Credibility, not conviction.
Decide
Collapse the state to one call.
Deterministic policy over the sensed state. Competing futures priced against one another. The output is a single, defensible action. Not a range, not a suggestion, not a nudge.
Prove
Sign it. Store it. Replay it.
Every call carries a cryptographic signature over its inputs, policy version, and output. Any future observer replays the decision and gets the same bytes. Nothing reconstructed. Nothing inferred.
“The model said so” is not an answer.
You've been buying indecision.
Fractured across dashboards, forecasters, copilots, and orchestrators, with you as the connective tissue. This is the first system that arrives whole. The final authority is still yours. What changes is what you're holding when you make it.
01
DecisionOS
The operating system
Takes in the evidence. Weighs it. Prices the alternatives. Makes the call. Or holds when the call isn't safe. Every call carries its own reasoning, ready to be replayed, defended, or overturned.
02
Decision Authority
The engine underneath
Same inputs and same policy. Same call. Every time. Every replay. Every audit. Where machine-learning systems drift and language models improvise, the Authority holds.
03
Decision Ledger
The record
A signed, tamper-evident record of every call. Inputs, alternatives, and the reasoning. Inspectable by your counterparty, your auditor, or a regulator.
04
Direct Benchmark
The proof-of-value
We run your history against your current stack, at our cost. The record decides. If REXEdge does not create measurable value, you keep the analysis.
Decision Ledger
Making the call is half the job. Defending it is the other half.
Six months from now, a counterparty, an auditor, or a regulator will ask why a specific decision was made in a specific interval. You answer with the record: the evidence, the assumptions, the alternatives, the confidence, the reasoning. Signed at the moment of the call.
Every decision becomes transparent. Replayable. Auditable. Not a black box.
Most enterprise software asks you to believe the demo. We run your history.
Energy gives us something almost no other industry does: a scoreboard. History already happened. The conditions are known. The markets settled. The outcomes are real.
01
Run the history.
Your data. Your operating conditions. Your constraints. Decision by decision. Interval by interval. Dollar by dollar.
02
Compare them.
What happened. What your process did. What REX/Edge would have done. The same signed audit trail the engine produces in live operation, applied to a historical window.
03
No strings.
If the engine does not create measurable value, you keep the analysis. We shake hands. Nobody wastes six months pretending there is a deal here.
Name the window. We'll run REX against your stack.
Let the record decide.
The grid edge, wherever it clears.
02
Virtual power plants
Aggregated DER portfolios optimized as a single dispatchable resource against market and reliability signals.
The call“Dispatch the aggregate, or protect the reserve margin?”
03
Storage
Front-of-meter batteries dispatching against real-time price and reserve products.
The call“Cycle now, or hold the state of charge for the evening peak?”
04
Flexible load
Industrial and behind-the-meter demand responding to interval prices and grid signals.
The call“Ramp the process down for the price spike, or run through and eat it?”
05
Renewables
Solar and wind operators deciding when to sell, curtail, or store. Reasoning signed and replayable.
The call“Sell into the negative price, curtail, or store what we can?”
06
EV fleets
Managed charging that answers to prices, tariffs, and grid constraints without breaking route commitments.
The call“Charge now at the cheap tariff, or wait and still make the 6am route?”
07
Beyond
Any market with a settlement interval, a scoreboard, and a call that has to hold up under audit.
The call“The interval closes. What did you decide, and can you prove it?”
