Preparing for FTR Auctions

The financial transmission rights (FTR) auction process is a financial mechanism used in electricity markets to manage the financial risks associated with the transmission of electricity across the power grid. By participating in FTR auctions, investors can hedge against price volatility and congestion in the transmission network (day-ahead energy market and day-ahead locational marginal price spread), reducing their exposure to financial losses.


Investors looking to participate in the various ISO administered annual and monthly FTR auctions must navigate a complex landscape of shifting policy and grid topology. Of note for ERCOT market participants is the recent Texas PUC approval of a performance credit mechanism, a major market reform over continued reliability concerns that will go before the state’s legislature this spring. 

Adding even more complexity to most U.S. markets in 2023 is the unstoppable force of renewable energy and related infrastructure. This includes a 10% increase in the investment tax credit (ITC) for wind and solar projects built within specific energy communities and up to a 20% ITC increase for Environmental Justice Areas, as defined in the Inflation Reduction Act (IRA). 

Whether trading, hedging, or a blend of both, market participants must shape their view of how systems and topology are changing with a complex array of data and analytical tools. To confidently bid and succeed in FTR auctions requires a rigorous methodology to track market events like outages to accurately inform FTR positions, trades and risk strategies. 

In this e-book, we will summarize some of the important factors FTR traders will need to review as they prepare for the FTR auctions and the considerations that need to be made: 

  • Weather 
  • Load growth 
  • Recently bound constraints 
  • Generation and transmission outages 
  • New and retiring generation 
  • Project delays 
  • Regulatory considerations

Comprehensive knowledge of weather patterns is crucial for successful preparation in FTR auctions, as they greatly influence load. Temperature directly affects electricity demand, while wind speed plays a vital role for wind farm power generation, allowing traders to identify potential trading opportunities by understanding its impact on surrounding areas.

One starting point to study the weather and its impact on the grid is by examining analog years that had similar weather patterns and observing what occurred. If you identify a year where similar weather conditions occur, you can examine what the grid looked like and which paths bound. This analysis can help you narrow down your areas for interesting paths. Note, grid infrastructure changes constantly, so if the analog years you are comparing to is more than a couple years back and there has been significant changes to the power infrastructure since then, the historical view of the grid is a less reliable indicator of what the grid understand similar weather conditions.

Monitoring drought conditions is also an important weather factor that can impact both load and power generation. When droughts occur, temperatures rise, causing higher load demand as water plays a critical role in keeping surrounding areas cool. Hydro power generation and thermal plants rely on water to generate power, so droughts will have a negative impact on how much power these power plants can generate.

Load Demand Growth

Demand refers to the amount of electricity that consumers need from the power grid at any given time. Understanding an area’s demand is important because it sets expectations for power prices and identifies potential areas where the power infrastructure may not be able to support the demand.

To predict where these potential areas may occur, it is helpful to investigate the expected growth in future load demand in an area, particularly if there are significant increases in demand. Rapid population or industrial growth, as well as the introduction of Bitcoin and rig operators, can result in significant increases in load demand.

It is also important to consider when these demand spikes will occur. For example, Bitcoin miners and some manufacturers require electricity 24/7, which can affect off-peak hours more than morning or evening peaks. Power operators must adjust their operations to meet these changing demands.

Bound Constraints

Analyzing past or recent constraints can provide valuable insights and guide future efforts to identify paths that may become constrained. To determine potential paths of interest, it is important to understand the underlying drivers of these constraints and predict whether they will persist in the future. Commercial diagnostic tools are available to aid in identifying the causes of constraints and building a case for their potential continuation.

After identifying a constraint driver, it is possible to use constraint analysis tools to simulate different scenarios and assess their impact on the affected paths. For instance, weather scenarios such as high or low wind, cold or hot temperatures can be inputted into the analysis tool to model the grid and identify potential paths that may become constrained. However, running these types of scenarios can be time consuming, and it is advisable to use automated constraint analysis tools to accelerate the process. These tools can significantly reduce analysis time, allowing users to examine hundreds of constraints in just a few minutes and focus on the most interesting paths.

Transmission and Generation Outages

Reports on transmission and generation outages provide valuable information on upcoming maintenance that will impact generation and paths on the grid. Reviewing and understanding these reports can help identify paths with a high likelihood of becoming constrained.

Users can dig into these reports and check historically how these same outages have impacted the grid and which paths had bound. Tools are readily available on the market that simulate the effects of transmission or generator outages on the grid, helping uncover potential paths that bind.

These simulations can be tedious, so it is recommended to use automated tools that can help reduce analysis time, sometimes by tenfold, so that the focus can be on preparing trades instead of analysis.

New and Retiring Generation and Transmission

Figure | ERCOT Actual and Projected Renewable Capacity

Getting a sense of where and when new generators or transmission lines will come online will bring clarity to what the electricity supply of the grid will look like. Once a date is determined for a new generator or transmission line, users can use tools to analyze its impact on the grid to existing constraints or its potential to create new constraints, bringing new opportunities to look at.

Similarly, when a generator or transmission line is taken offline, analysis can be done to see how its decommissioning will impact the grid.

Project Delays

Figure | ERCOT Solar Delays

When power projects are delayed, power that was expected to come online will be later than originally anticipated. As a result, positions that were based on those original timelines will need to be adjusted. Staying informed about the latest updates on power project timelines can provide an opportunity for traders to adjust and capitalize on the new projected start date.

Regulatory Considerations


It is important to keep on top of regulatory changes as they can have a significant impact on the power markets. For example, changes in regulation could affect the cost of generation, transmission or distribution of power, which will impact your trading strategy. Additionally, regulatory changes could lead to changes in the availability of FTRs or the rules governing their trading, which could also affect the market dynamics and FTR prices. Reports and analysts are available in the market who regularly stay on top of these changes and summarize and report on the changes to help make sure FTR traders are up to date on the regulation and its potential impact for FTR auctions.

After completing the analysis and identifying attractive trading constraints, it is essential to determine the appropriate price to pay for them. Fortunately, there are numerous tools available that can forecast prices and break down the drivers of congestion costs, allowing users to understand where the congestion price is coming from. Additionally, traders can use tools to view other traders’ portfolios and trading activities, providing insights into which paths are worth pursuing and at what price. For a more in-depth discussion of pricing tools and strategies, a separate e-book will be available.
