Why the forecast is the edge
Short-term power prices are set by renewable output. A desk that knows tomorrow's solar and wind feed-in a few percent better than the market has an edge in every day-ahead auction and intraday ramp; a desk that does not is trading against it. Building that forecast in-house means weather-data licences, satellite feeds, asset telemetry and a data-science team — and the model still has to be maintained around the clock.
SAMAWATT offers renewable forecasting for traders as an API: asset-level solar and wind forecasts, bidding-zone aggregates and price forecasts on the same 15-minute horizon our own trading engine uses.
How the API connects to your desk
The energy trading API has two integration levels: pull forecasts into your own strategies, or send signals and use execution as a service through SAMAWATT's auto-trader. Both run on the same documented REST and streaming interface with sandbox keys.
- 1Connect the forecast APISubscribe to asset-level and zone-level solar, wind and price forecasts; updates stream every 15 minutes.
- 2Run your strategyFeed the forecasts into your own models or use SAMAWATT's signal library; your P&L and risk limits stay on your side.
- 3Execute through the auto-traderOrders are routed through SAMAWATT's ISV-certified connections to EPEX SPOT and ETPA with sub-15-minute latency.
- 4Monitor and reconcileFills, positions and exchange reports are returned via the API and reconciled against your trade capture system.
Where the margin comes from
Intraday margins live in the minutes after a forecast changes. Managed exchange connectivity with sub-15-minute signal-to-fill latency lets algorithmic intraday trading strategies capture ramps and shadow events before the spread closes. Reserve and imbalance markets, normally closed to desks without prequalified assets, become accessible through SAMAWATT's aggregated portfolio, adding ancillary revenue to a pure spot book.
Desks pay a data subscription and a per-MWh execution fee; there is no exchange membership, connectivity maintenance or 24/7 operations cost on your side.
What the platform includes
SAMAWATT's short-term power trading platform executes several thousand orders a day for its own portfolio and for partner desks and brokers, and is ISV-certified by EPEX SPOT and ETPA. SAMAWATT trades on its own account, so our capital faces the same prices as yours, and we own no generation assets. The optimization and execution layer is the same one our utility and aggregator clients run on.
