IU

intermediate_unit

Intermediate-term service from a designated generating unit. The same as LU service expect that “intermediate-term” means longer than one year but less than five years.

LF

long_firm

Long-term firm service. “Long-term” means five years or longer and “firm” means that service cannot be interrupted for economic reasons and is intended to remain reliable even under adverse conditions (e.g., the supplier must attempt to buy emergency energy from third parties to maintain deliveries of LF service). This category should not be used for long-term firm service firm service which meets the definition of RQ service. For all transaction identified as LF, provide in a footnote the termination date of the contract defined as the earliest date that either buyer or seller can unilaterally get out of the contract.

LU

Long-term service from a designated generating unit. “Long-term” means five years or longer. The availability and reliability of service, aside from transmission constraints, must match the availability and reliability of the designated unit.

OS

Use this category only for those services which cannot be placed in the above-defined categories, such as all non-firm service regardless of the Length of the contract and service from designated units of Less than one year. Describe the nature of the service in a footnote for each adjustment.

RQ

requirement

Requirements service. Requirements service is service which the supplier plans to provide on an ongoing basis (i.e., the supplier includes projects load for this service in its system resource planning). In addition, the reliability of requirement service must be the same as, or second only to, the supplier’s service to its own ultimate consumers.

final

Data that has been reviewed and validated by the publishing agency, and is considered to be in its final form. Note that even final data is subject to later revision, sometimes years after the fact.

provisional

An early draft of final release data, that has not yet been fully reviewed or validated by the publishing agency. Should be used with caution. E.g. Early Release versions of the complete annual EIA-860 and EIA-923 data.

monthly_update

Data that is updated monthly throughout the year, but that is not monthly in resolution. Should be used with caution, as it may be revised when incorporated into final annual reporting. E.g. the generator attributes reported in the EIA-860m.

incremental_ytd

Incremental releases of data with sub-annual resolution. Should be used with caution, as in many cases not all respondents are required to report at sub-annual frequency, meaning data coverage may not be complete. This data is also likely to be revised prior to its final annual release. E.g. the EIA-923 monthly or FERC Form 1 quarterly data releases.
