For licensed electricity traders
Buy from many, sell to many.
A trader owns no meter and carries both sides of a book. Webill Green runs your trader pools from licence file to monthly statement: who you buy from, who you sell to, the hours each side covers, and your margin hour by hour, under four-eyes risk controls.
The trader's market
Traders took 56% of the 4.7 GW financed between 2023 and 2025, and hold an 18 GW pipeline.
Every one of those megawatts is two contracts, a purchase and a sale, that have to settle against each other, hour by hour, across two networks and soon a wholesale market.
The right hours matter as much as the price.
Two curves with the same daily total can still leave a book long at noon and short at night. Pick a supply shape and see where the hours fail to meet.
- Daily demand, and daily supply
- Matched in the right hour
- Long
- Short
Illustrative profiles, each scaled to deliver exactly what the buyer uses in a day. The whole-day totals match every time; the hours do not.
One book, two connected needs.
The Desk sells the long and buys the short. Buy candidates are ranked against the book's gap and load shape; sell candidates against what the book has spare. A good trade improves the whole book, beyond its own price tag.

A chain that reconciles itself.
A trader sits between contracts. On the 1st of every month, chain reconciliation checks that the volumes and the margin add up from the generator, through each trader, to the buyer.

Your margin, every hour
Sell, less buy, less wheeling, across about 8,760 hours a year. Pools can chain to other pools, trader to trader, and each link is its own contract with its own statement.
- Nominations are binding: settlement reads them where no meter can speak, and imbalance is judged against them
- Proposals for next month arrive on the 20th
- Batteries in the book are planned with the rest of it: dispatch is part of the strategy run
Four eyes on every lever that moves money.
Risk limits, the kill switch and the automation level change only through four-eyes approval. The engine computes and proposes; a person confirms. NERSA's draft trading-platform framework would bar automated trading for five years, so the desk defaults to human confirmation.
- Risk limits on exposure, with margin and value-at-risk fan charts beside them
- A kill switch for automated actions
- Onboarding that waits for evidence: licence, network roles, activities and limits
Bid the book's net position.
Your BRP seat bids the pool's net position into the day-ahead auction before 10:00 SAST the day before, corrects undelivered hours in five intraday auctions and answers for imbalance after delivery, all on a market clock in SAST.
