LCG, September 30, 2025--Vistra Corp. announced yesterday that it will proceed with the next phase of its capital plan to support grid reliability in Texas. In 2024, Vistra identified over $1 billion worth of potential capital additions in generation capacity within the Texas ERCOT market by 2028 if market conditions were supportive. Now, with West Texas' growing power requirements, particularly the state's expanding oil and natural gas industries, Vistra reached a final investment decision and confirms it will build two new advanced natural gas-fired power units on-site at its Permian Basin Power Plant.

SPP Integrated Marketplace March 2014 marks the start of the completely redefined market structure in the Southwest Power Pool (SPP), termed the “Integrated Marketplace”. This is a significant transition and includes an entirely new approach to coordinating power production, consumption, reliability and settlement. Where previously 16 Balancing Authorities committed their own generation and market prices were relevant only for the amount of power utilized for balancing, the Integrated Marketplace will include a centralized commitment and market prices for the forward (Day Ahead) and Real Time markets. In addition, a number of co-optimized products will be offered.
Market Participants will be able to utilize co-optimized markets along with new market instruments to operate more strategically in the Marketplace such as:
- Bilateral Settlement Schedules
- Transmission Congestion Rights
- Virtual Transactions
To understand the new SPP Market and how it operates, it is helpful to investigate the fundamental elements which drive it. By looking at the fundamentals along with the protocols that will govern market operations, we can gain tremendous insight into what to expect.
Using UPLAN, an integrated fundamental model which has been designed to simultaneously replicate the physical and financial operations of the power system, LCG has run comprehensive, chronological simulations of SPP to determine how the system will operate. Some observations from these simulations follow.
Locational Marginal Price Forecast - High prices will be found around the Kansas-Oklahoma border and Texas-Panhandle.
- Low prices are forecast for the southwestern border (SUNC, NPPD).
SPP is aggressively adding transmission, including a number of recently completed 345kV projects. The 2013 SPP Transmission Expansion Plan (STEP) includes $6.7Billion in projects and will be included as appropriate with realistic in-service dates within LCG’s simulations.
Even so, price spreads will be seen throughout the footprint. For more information on the SPP Integrated Marketplace, the forecasting tools used to predict the congestion and prices that can be expected or any other queries, please contact:
