Nine new articles have been proposed for the 2017 edition of NFPA 70, National Electrical Code®, three of which focus on the generation, distribution, and storage of electrical power, says Jeff Sargent, regional electrical code specialist.
Proposed Article 691 covers photovoltaic supply stations that can generate 5,000 kilowatts or more. These systems differ from those covered in existing Article 690, in that the power they generate only supplies electric utility transmission or distribution systems at medium or transmission-level voltages.
Proposed Article 706 covers permanently installed systems that can stand alone or interact with other electric power production sources. This article would centralize the requirements for all energy storage technologies into a single NEC article.
Finally, Proposed Article 712 covers direct-current power systems where DC sources supply power directly to a distribution system that supplies such equipment as LED lighting, communications equipment, and computers and servers.
