4 Colo. Code Regs. § 723-3-3854

Current through Register Vol. 47, No. 22, November 25, 2024

Section 4 CCR 723-3-3854 - Level 1 Process (25 kW Inverter Process)

This rule establishes the procedures for evaluating an interconnection request for a certified inverter-based interconnection resource no larger than 25 kW AC which may be paired with a non-exporting energy storage system no larger than 25 kW AC. The application process uses an all-in-one document (application) that includes a simplified interconnection request, simplified procedures, and a brief set of terms and conditions.

(a) General Level 1 procedures.

(I) The IC completes application and submits it to the utility.

(II) The utility acknowledges to the customer receipt of the application within three business days of receipt.

(III) The utility evaluates the application for completeness and notifies the customer within ten business days of receipt that the application is or is not complete and, if not, advises what material is missing.

(IV) Within ten business days, the utility shall verify whether the interconnection resource can be interconnected safely and reliability using the same screens as applied in Level 2 Process as set forth in rule 3855 except for screens (V), (VI), (X) and (XI) which will not be deemed necessary for the Level 1 Process (25 kW AC Inverter Process). If the interconnection fails these screens, the utility shall generally consider this a failure of the Level 2 Process screens in rule 3855. The utility shall continue the interconnection review under the Level 2 Process, starting at paragraph 3855(c), provided that the IC pays the difference in the Level 2 Process application fee and deposit requirements. The utility may also review the application within the ten-business day period to evaluate issues associated with highly seasonal circuits. However, if the proposed interconnection fails the screens, but the utility determines that the small generating facility may nevertheless be interconnected consistent with safety, reliability, and power quality standards, the utility shall provide the IC an executable interconnection agreement within five business days after the determination.

(V) Provided all the criteria of this rule 3854 are met, unless the utility determines and demonstrates that the interconnection resource cannot be interconnected safely and reliably and requires upgrades, the utility approves and executes the application and returns it to the customer within ten business days.

(VI) After installation, the customer returns the certificate of completion to the utility. Prior to parallel operation, the utility may inspect the interconnection resource for compliance with standards, which may include a witness test, and may schedule appropriate metering replacement, if necessary. The utilities should define "witness test" in their interconnection tariff.

(VII) The utility shall notify the customer that parallel operation of the interconnection resource is authorized within ten business days of the certificate of completion. If the witness test is not satisfactory, the utility has the right to disconnect the interconnection resource. The customer has no right to operate in parallel until a witness test has been performed, or previously waived on the application. The utility is obligated to complete this witness test within ten business days of the receipt of the certificate of completion.

(b) Level 1 application.

(I) The customer must provide in the application the contact information for the legal applicant (i.e., the interconnection customer). If another entity is responsible for interfacing with the utility, that contact information must be provided on the application.

(II) The application is considered complete when it provides all applicable and correct information as required below. Additional information to evaluate the application may be required.

(III) The application shall include the following information, as applicable:

(A) Processing fee. A fee of ____________ must accompany this application.

(c) Level 1 terms and conditions.

(I) Construction of the facility. The interconnection customer may proceed to construct the interconnection resource when the utility approves the interconnection request (the application) and returns it to the IC.

(II) Interconnection and operation. The IC may operate the interconnection resource and interconnect with the utility's electric system once all of the following have occurred:

(A) upon completing construction, the interconnection customer will cause the interconnection resource to be inspected or otherwise certified by the appropriate local electrical wiring inspector with jurisdiction;

(B) the customer returns the certificate of completion to the utility; and

The utility shall provide a written statement that the interconnection resource has passed inspection or shall notify the customer of what steps it must take to pass inspection as soon as practicable after the inspection takes place.

(D) The utility has the right to disconnect the interconnection resource in the event of improper installation or failure to return the certificate of completion.

(III) Safe operations and maintenance. The interconnection customer shall be fully responsible to operate, maintain, and repair the interconnection resource as required to ensure that it complies at all times with the interconnection standards to which it has been certified.

(IV) Access. The utility shall have access to the disconnect switch and metering equipment of the interconnection resource at all times. The utility shall provide reasonable notice to the customer when possible prior to using its right of access.

(V) Disconnection. The utility may temporarily disconnect the interconnection resource as allowed in the interconnection agreement and upon the following conditions:
