Reliable bidding where it matters most.

Auctions still account for the largest volumes in short-term power markets, and a single mistake can set you back for the entire year.

Automate auction bidding with real-time validation and portfolio-level control.

Auction markets still represent the dominant share of volumes, and with that much money at stake, reliability and risk management are absolutely key. Volue Auction Trader centralizes and automates your day-ahead and intraday auction workflows, letting you generate, validate, and submit bids in seconds, then track results and disaggregate them back across your asset or portfolio structure.

Built multi-exchange by design, it offers broad and expanding exchange coverage across Europe, so you can switch between EPEX and Nord Pool through a single, consistent interface. Visualize and audit your bids and results with ease. Delivered as SaaS, it plugs into your optimization stack via REST API and Trade Gateway/Mesh for streamlined data flow and faster, smarter bid preparation.

Submit validated price-volume curve orders for Day-Ahead auctions on EPEX SPOT, Nord Pool, and all other supported exchanges — from a single platform. Automated aggregation across your full portfolio means no manual consolidation before the gate closure.

Participate in IDA1, IDA2, and IDA3 auctions on EPEX and Nord Pool with the same validated workflow you use for Day-Ahead. No separate tools, no context switching — the same interface, the same risk controls, across all auction windows.

Configure hierarchical portfolios — from portfolio level down to individual plant or unit — and let Auction Trader handle aggregation and disaggregation automatically. All standard block order types are supported: standard, linked, exclusive group, and loop/spread blocks. Designed for the operational complexity of hydro cascades, thermal ramps, and battery storage assets.

Import bid suggestions directly from your optimization tools via REST API, time series import, or structured bid document upload. Inspect, validate, and execute — without re-entering data manually.
