Technology · Energy Management System
The brain that trades your energy — buying cheap, selling peak.
Every WLF system decides, minute by minute, whether to charge, discharge, buy from the grid or sell to it. That decision is worth €20–50K per MW per year — and it is the revenue engine competitors selling hardware alone do not have.
How it earns
Four revenue streams, running simultaneously.
Spot price arbitrage
Buying energy when prices are low. Selling when they are high. Automatically, minute by minute.
FCR / FFR frequency response
Grid-stability services the operator pays your system to provide.
Capacity auctions
Long-term contracted availability payments for being ready when the grid needs it.
Self-consumption optimisation
Prioritising your own on-site load to displace expensive grid draw.
Stacked revenue
Your system earns in four different ways at once.
Because WLF owns the whole stack, the EMS is not bolted on — it is embedded. Hardware drives the EMS, the EMS drives trading, trading drives O&M. Every megawatt compounds all four.
