I frequently get asked, “what is the difference between the Institute of Electrical and Electronics Engineers (IEEE) stationary battery maintenance standards and those promulgated by the North American Electric Reliability Corporation (NERC) in PRC-005?” My stock answer is, “lots.”
First of all, a little bit of history and a lot of acronyms. In 2003, the Northeast of the Unites States and parts of Canada suffered a massive blackout which demonstrated the vulnerability of the National Bulk Electrical System (BES). As a result, the Federal Electrical Reliability Commission (FERC) established the Electrical Reliability Organization (ERO). The ERO gave responsibility to the National Electric Reliability Corporation (NERC) to come up with standards that were intended to improve the reliability of the BES.
