Engineering Standards, Specifications and Technical Bulletins

Important Note:

The following Standards, Specifications, and Technical Bulletins were developed by LUMA in accordance with its responsibilities under the T&D OMA and in compliance with applicable law, regulation, industry standards and practices and are the standards, specifications, and technical bulletins currently applicable to any design and construction activities performed by LUMA or its contractors. They are effective from their approval dates, unless stated otherwise.

With regards to any third-party design or construction of electrical system infrastructure that will be transferred to PREPA’s T&D System, please refer to the standards, specifications and technical bulletins and manuals previously published by PREPA. LUMA intends to update or replace any outdated and obsolete PREPA standards, specifications, and technical bulletins. LUMA will provide prompt and prior notice before any new standard, specification or technical bulletin that replaces existing PREPA requirements becomes effective. Until then, these standards, specifications and technical bulletins are listed for illustrative and informational purposes only. Notwithstanding, to assist in modernizing the T&D System and increase overall resiliency, LUMA encourages all third parties seeking to design and construct electrical system infrastructure to voluntarily apply and follow the following standards, specifications, and technical bulletins.
