Thermal power
Baseload and mid-merit coal units with minimum stable generation, start-up and shut-down costs, ramp limits and deep peak-shaving capability.
Market participants
Nine participant models, each with real constraints
In ElecSim a participant is not just a name on an order book. Every type carries its own physical limits, cost structure and bidding behaviour, so the strategies that work in reality are the ones that work here.
- 9 Market participant types
- 3 Generation · Flexibility and storage · Demand side and retail
Generation
05Gas
Fast-start and combined-cycle units with fuel price linkage, heat rate curves and heat-power coupling.
Hydro
Reservoir and run-of-river units with inflow series, water head, spillage and seasonal energy budgets.
Wind
Forecast-driven output with error bands, curtailment, and the deviation exposure that comes with both.
Solar PV
Daylight-shaped output, forecast deviation and curtailment, from utility-scale farms down to distributed rooftops.
Flexibility and storage
02Pumped storage
Pumping and generating modes, reservoir state of charge, round-trip efficiency and capacity tariff recovery.
Energy storage
Charge and discharge schedules, state of charge, degradation cost, and stacked revenue from energy and ancillary services.
Demand side and retail
02Retailers
A retail portfolio, contract signing limits, deviation risk, and the pass-through of spot prices to end users.
Virtual power plants
Aggregated distributed resources bidding into the market as a single block, carrying demand response and availability commitments.
Every asset has a cost curve, not just a capacity figure
A 600 MW coal unit that cannot ramp below 300 MW bids differently from a battery that can swing in seconds. ElecSim models those differences, so the clearing result reflects the physical plant standing behind each order.
Under the hood
What every participant model carries
Physical parameters
Capacity, ramp rates, minimum stable generation, state of charge, reservoir limits and start-up times.
Cost structure
Fuel and start-up costs, degradation cost, heat rate curves and the opportunity cost of not producing.
Market behaviour
Bidding strategy, risk limits, credit limits and position limits that constrain what a participant may offer.
