Section 30 000 055 - INTERCONNECTION PROCEDURES FOR PROPOSED ELECTRIC GENERATION RESOURCES (5.500)

Section 5.501 Applicability

This Rule applies to all proposed interconnections of Generation Resources within the State of Vermont which are not (i) lawfully subject to ISO-NE interconnection rules or successor rules approved by FERC, or (ii) subject to the Board's net metering rule (Rule 5. 100), for which the interconnection provisions of those rules will govern. This Rule does not apply to facilities within the State of Vermont that were interconnected or had obtained all necessary approvals for interconnection with electric power transmission or distribution systems prior to 60 business days after the effective date of this Rule.

Section 5.510 Codes and Standards

When any listed version of the following codes and standards is superseded by a revision approved by the standards-making organization, then the revision shall be applied under Section 5.505. Applications that are date-and-time-stamped on or before six months after the revision date may follow the previous version of the standard, unless an immediate threat to safety and reliability exists that requires the retrofit of all similarly situated equipment. Applications that are date-and-time-stamped later than six months after the revision date must follow the revised standard.
