Status:
The drafting
team has posted the consideration of comments for the
BAL-004-1
SAR Version 1.
Purpose/Industry Need:
The Resources Subcommittee proposes revising BAL-004-0, to incorporate manual and
automatic time error correction reliability requirements and measures;
add three terms to the NERC Glossary of Terms related to this proposed
standard; and include a regional difference for the Eastern
Interconnection Regional Reliability Organizations.
The Resources Subcommittee recommends these Time Error Correction reliability
requirements under all conditions. Time Error Correction affect each interconnection's frequency profile
which has serious reliability implications. Every NERC reliability standard calculation that uses scheduled
frequency is affected by this standard. Automatic time error correction will drive Balancing Authorities
to pay back their frequency deviations in a relatively prompt manner
after the deviations occur (within a matter of hours).
Note: The SAR drafting team will work
cooperatively with NAESB to revise this standard to assure it is
developed in harmony with the NAESB business practices standard(s).
