FERC Form 714 provides an overview of balancing authorities, including hourly demand, system lambda (the energy component of locational marginal prices within a balancing authority area) and additional metrics. FERC Form 714 is reported annually by around 250 balancing and planning authorities. Data is available as consistently formatted CSV files for 2006 through 2017. The total uncompressed size of the 2006-2017 dataset is around 250MB consisting of tens of millions of records.
Why is it useful/interesting?
The historical hourly demand within a planning area is a fundamental constraint for energy system models used to determine resource adequacy. In order to understand what kinds of resources can be added to or removed from a planning area without impacting system reliability, modeling with at least hourly resolution is required. The 10 year forecast of future peak loads and net energy demand are also important constraints for evaluating the adequacy of planned resources. Knowing what connections exist between balancing authorities is important for developing larger scale models of the grid for transmission system modeling.
Who would use it?
- Users trying to understand the feasibility of replacing existing or proposed fossil generation with renewable resources, electricity storage, DSM programs, or other alternative investments.
- Users doing larger scale electricity system operations modeling, who need to understand the network of connections between different planning areas and balancing authorities.
What information is included in this dataset?
- Hourly system demand reported by planning area
- Hourly system lambda ($/MWh) reported by balancing authority
- 10 year forecast of the peak summer and winter loads, and net annual energy demand
- Annual peak demand on a per-plant basis
- Monthly capacity available / unavailable at time of peak monthly demand
- Monthly net generation and interchange with other balancing areas
- Amount and sources of load and generation at time of monthly peak demand
- Monthly peak and minimum demand
- List of connections to adjacent balancing areas and their voltage
- Scheduled and actual MWh exchanged with adjacent balancing areas
- Peak summer and winter demand for each utility in the balancing area
Risks & Challenges
Many entities (plants, utilities, balancing authorities) reported in FERC Form 714 are identified by a freeform name rather than a unique ID. These names are not necessarily reported identically from year to year, and may not have programmatically usable linkages to corresponding entities in other datasets. In order to effectively utilize the data, unique identifiers will need to be associated with the various named entities. The challenges of this dataset are similar to those we faced with FERC Form 1, and similar techniques for assigning unique IDs to entities reported differently from year to year should be applicable.
Uniform units and formatting are not enforced for many numerical fields, meaning some error correction will be required. For example, some utilities report interconnection voltage in kilovolts, and others report in Volts. When multiple interconnections exist this numerical field may include more than one voltage without any separator (e.g. if both a 345kV and a 115kV interconnection exist, it may be reported as 345115).
