Key components of the SPP integrated marketplace
1. Energy and operating reserve markets
- Day-Ahead Market (DAM): Allows participants to submit bids and offers for energy and operating reserves for the next day, ensuring efficient scheduling of generation and load.
- Real-Time Balancing Market (RTBM): Operates in real-time to balance supply and demand, addressing discrepancies from the Day-Ahead Market schedules using Security-Constrained Economic Dispatch (SCED). Read our blog post, “Day Ahead vs. Real-Time Market: What’s the Difference?”
- Operating reserves: Backup resources to ensure reliability in case of unexpected demand spikes or generation shortfalls, with Reserve Zones established to ensure deliverability throughout the Balancing Authority Area (BAA). Read our blog post, “Understanding the Role of Balancing Authorities.”
2. Transmission Congestion Rights (TCR) markets
- TCR auctions: Allow market participants to acquire rights that hedge against congestion costs in the transmission network, providing financial compensation for congestion charges incurred during energy delivery. Learn more in our blog post, “Understanding Transmission Congestion Rights.”
- Annual and monthly auctions: Conducted to allocate TCRs, helping participants manage their congestion risk over different time horizons.
