Concerned about performing zonal trading in MISO? As an energy trader, it can be challenging to set up zonal trading to achieve performance and risk objectives in the Midcontinent Independent System Operator (MISO).
Let’s dive into how MISO zonal trading works and its advantages and disadvantages.
The Midcontinent Independent System Operator (MISO) spans 15 US states and the Canadian province of Manitoba. Within MISO, one of the essential concepts for market operations is zonal trading. This approach helps balance supply and demand, manage congestion, and optimize resource utilization within the energy market.

MISO is divided into zones, with each zone representing a geographical area with specific generation and load characteristics. These zones aggregate transmission nodes to simplify market operations. By grouping nodes into zones, MISO can streamline energy pricing, congestion management, and resource scheduling.
In the MISO market, zonal trading operates in conjunction with locational marginal pricing (LMP), which reflects the cost of delivering the next unit of electricity to a specific location, considering generation costs, transmission constraints, and losses.
Transmission nodes within a geographical area are grouped into a single zone. This aggregation simplifies market operations by reducing the number of variables MISO must analyze in its market-clearing process.
MISO assigns each zone a price, which is the average LMP of the nodes within that zone. Market participants operating within a zone pay or receive this zonal price for energy transactions.
Zonal trading helps identify and manage grid congestion. If transmission constraints arise, MISO uses re-dispatch strategies to ensure electricity flows efficiently while maintaining grid reliability.
Zonal trading is integral to MISO’s day-ahead and real-time markets. In the day-ahead market, zonal prices are forecasted based on expected supply and demand. In the real-time market, prices are updated to reflect actual conditions.
By aggregating nodes, zonal trading reduces computational complexity and makes it easier for market participants to plan and execute trades.
Zonal pricing offers a clear and predictable framework for energy transactions, enabling market participants to make informed decisions.
By identifying zones where congestion is likely, MISO can implement measures to optimize power flows and minimize disruptions.
Zonal trading lowers the barrier to entry for smaller market participants, such as distributed energy resources (DERs), by offering a simplified pricing mechanism.
Aggregating nodes into zones may obscure localized issues, such as transmission bottlenecks or generation shortages, leading to inefficiencies.
Unexpected events, such as generator outages or sudden demand spikes, can influence zonal prices, causing price volatility.
In smaller zones, dominant generators may exert market power, impacting competition and price fairness.
