The problem
Every day, Alpiq's traders bid a 900 MW pumped-storage plant into the day-ahead market, hours before prices are known. Bid too boldly and a bad-price day costs a fortune; bid too cautiously and money is left on the table.
What we built
A bidding engine that plans the plant's turbines and pumps across many possible price scenarios, with one dial that sets how much risk the desk is willing to take. Every bid respects the plant's real technical limits.
The result
Tested on four months of real cleared prices from 2021–2022, it would have earned €0.9M (+3.2%) more than the standard approach. Turning the risk dial cuts losses on bad days by about 70%, for 2.5% less expected profit.
