AES participates actively in all three pillars of the Romanian wholesale electricity market, offering a fully integrated approach to energy trading and portfolio management.
The Day-Ahead Market (PZU) is the primary venue for scheduling electricity delivery in Romania. Operated by BRM (Bursa Română de Mărfuri), it runs a daily auction where buyers and sellers submit bids for each of the 24 hourly intervals of the following day.
AES develops data-driven bidding strategies to maximize value for our clients, combining fundamental analysis, weather forecasting, and cross-border flow data.
Statistical and ML-based models to anticipate next-day price levels and shape.
Hourly and block bids crafted to capture peak/off-peak spreads and volume flexibility.
Real-time tracking of accepted bids and exposure against contracted volumes.
Integration of ENTSO-E NTC data and neighboring market prices into strategy.
The Intraday Market allows participants to trade electricity throughout the operating day, enabling adjustments to positions after Day-Ahead market closure. It is critical for managing deviations caused by demand changes, renewable generation variability, or unexpected outages.
AES operates continuously on PCINT through both the continuous trading session and intraday auctions, reacting swiftly to real-time developments in the Romanian and regional grid.
Active participation in the continuous session for immediate buy/sell execution.
Specialized strategies for wind and solar generators to minimize imbalance costs.
Real-time generation and load forecasting driving timely trading decisions.
Proactive position correction to avoid costly BRP settlement penalties.
Ancillary services are essential for maintaining the stability and reliability of the Romanian national power grid. Transelectrica, as the Transmission System Operator (TSO), procures these services from qualified providers to maintain frequency at 50 Hz and manage real-time imbalances.
AES acts as an aggregator and direct provider of ancillary services, enabling generators and large consumers to access these markets and benefit from additional revenue streams.
Fast-acting reserves to contain frequency deviations within seconds of a disturbance.
Automatic and manual frequency restoration reserves to return frequency to 50 Hz.
Pool smaller flexible assets to meet minimum capacity thresholds for market entry.
Full adherence to Transelectrica technical requirements and ANRE regulations.
