Network upgrades shall be assigned to large load customers through the interconnection study process that is part of the load interconnection queue system established under this subsection.

Interconnection to the interstate transmission system for a large load facility shall not proceed until the applicable transmission provider determines that the interconnection would not cause a violation of any applicable Commission-approved reliability standards (as defined in section 215(a)).

Interconnection to the transmission system shall not be approved for a large load customer unless the large load customer satisfies the following criteria:

The large load customer—

(I) is technically capable of exercising demand flexibility and being curtailable, as evidenced by satisfaction of—

(aa) the minimum criteria established under subparagraph (B); and

A transmission provider shall endeavor to complete the interconnection study process for a large load customer that satisfies the criteria for prioritization under this paragraph before other large load customers that do not satisfy the criteria for such prioritization.

Transmission providers shall provide to colocated large load facilities non-firm transmission access to the transmission system for the purpose of withdrawing electric energy from the transmission network on an as-available basis, subject to the condition that such non-firm transmission service shall be—

(A) subject to curtailment or interruption before firm network or point-to-point transmission service, in accordance with the open access and reliability standards of the Commission; and

(B) priced to reflect the non-firm nature of such service.

Transmission providers offer to colocated large load facilities injection rights without the need for deliverability studies if the injection will occur on a non-firm basis.

The Commission shall require transmission provider tariffs provided to the Commission to specify the following:

(1) An existing generating facility operated by an interconnection customer may not, as a result of any request of the interconnection customer to modify its interconnection service level for such existing generating facility, withdraw any of its capacity to begin serving a large load facility if the withdrawal of capacity from the existing generating facility to serve a large load facility would result in a loss of capacity to serve customers other than the large load facility without a new generation resource being interconnected to the grid to compensate for such loss of capacity.

(2) An existing generating facility operated by an interconnection customer may not, as a result of any request of the interconnection customer to modify its interconnection service level for such existing generating facility, withdraw any of its capacity to begin serving a large load facility until all modifications to interconnection facilities and network upgrades that the transmission provider determines to be necessary to maintain reliability for existing customers are carried out and placed in commercial operation.

Not later than 1 year after the date of enactment of this section, the Commission shall issue a final rule requiring transmission providers to ensure that a large load customer seeking interconnection to the interstate transmission system shall be responsible for 100 percent of the network upgrades that are assigned to the large load customer pursuant to 1 or more interconnection studies, including any additions, modifications, or upgrades to the interstate transmission system at or beyond the point of interconnection that, in the determination of the transmission provider, are required—

(i) to accommodate the interconnection; or

(ii) to maintain the reliability or operational integrity of the transmission system.

All payments made by a large load customer to cover the costs of network upgrades described in subparagraph (A) shall be nonrefundable.

The Commission shall not approve any tariff submitted to the Commission for review to include any crediting mechanism, refund, or offset that allows for the costs of network upgrades described in subparagraph (A) to be—

(i) recovered from any transmission customer other than the applicable large load customer described in that subparagraph; or

(ii) credited against future transmission or retail service charges.

The costs of network upgrades described in subparagraph (A) shall be directly assigned to the applicable large load customer through a Commission-jurisdictional payment mechanism, such as—

(I) a non-refundable upfront payment;

(II) a structured surcharge that may be paid over time; or

(III) any other cost-assignment mechanism that is within the jurisdiction of the Commission.

The Commission may require that payments to cover costs described in clause (i) be included in each applicable open access transmission tariff.

The payment of network upgrade costs described in clause (i) through a Commission-jurisdictional payment mechanism described in that clause shall not preempt the authority of a State commission to regulate the retail rates, terms, or conditions of electric service provided to the applicable load by a retail utility.

For a colocated large load facility—

(A) the applicable large load customer shall be assessed charges on a gross-demand basis for ancillary services and black start service provided through the interstate transmission system if the colocated generating facility is interconnected to the interstate transmission system, even if the colocated large load facility withdraws zero net energy from the interstate transmission system; and

(B) the existence of on-site generation, energy storage, or other behind-the-meter resources shall not relieve a colocated large load facility of cost responsibility under subparagraph (A) if the facility remains interconnected with, synchronized to, or reliant upon the interstate transmission system for reliability, backup service, or ancillary services.

In determining the justness and reasonableness of any rate, charge, term, or condition of a tariff or tariff amendment filed under section 205, the Commission shall, consistent with State authority, review the cost allocation methodologies to ensure that the costs of transmission services, network upgrades, or related facilities necessitated by the interconnection or operation of large load facilities are not shifted to other customers, including by taking into account the ultimate impact of rates under the jurisdiction of the Commission on downstream retail ratepayers.

Energy generated by a colocated generating facility that is in excess of the amount consumed by the colocated large load facility and that is injected into the interstate transmission system shall be compensated at the applicable wholesale locational marginal price or the avoided cost rate, in accordance with the relevant tariff of the transmission provider that has been filed with and approved by the Commission.

Not later than 1 year after the date of enactment of this section, the Commission shall initiate a rulemaking to revise the pro forma Large Generator Interconnection Procedures promulgated pursuant to section 35.28(f) of title 18, Code of Federal Regulations (or a successor regulation), to require public utility transmission providers to share and employ, as appropriate, queue management best practices with respect to the use of computing technologies, such as artificial intelligence, machine learning, or automation, in evaluating and processing generating facility interconnection requests within a generator interconnection queue, in order to expedite study results with respect to those requests.

Subject to the availability of appropriations, the Secretary shall provide to transmission providers technical assistance with respect to the implementation of any best practices established by the Commission under paragraph (1), as the Secretary determines to be appropriate.

The Commission shall require that, in at least 1 category of load forecast utilized by a transmission provider for estimating future energy demand or making grid planning decisions, a large load facility may be included in the forecast only if the large load facility is able to provide proof of viable demonstration of commercial or operational commitment pursuant to objective criteria set forth in a Commission-approved tariff, which may include—

(1) an energy or transmission service agreement;

(2) credit or collateral support;

(3) significant infrastructure investment;

(4) a long-term generation supply commitment; or

(5) any other comparable demonstration of commitment approved by the Commission.

Notwithstanding any other provision of law, the Commission shall require each transmission provider, as a condition of accepting and processing an interconnection request, transmission service request, or comparable request from a large load facility, to impose—

(A) study deposits sufficient to cover the costs of system impact, facilities, or comparable studies;

(B) readiness or milestone payments tied to progression through the study and interconnection process; and

(C) withdrawal penalties designed to ensure that a large load facility that withdraws from such process bears an appropriate share of the costs imposed on the transmission provider and other customers.

The requirements established under paragraph (1) shall be designed—

(A) to discourage speculative requests; and

(B) to reduce study delays and restudies.

Not later than 180 days after the effective date of each final rule issued under subsection (b), each transmission provider subject to the jurisdiction of the Commission shall submit to the Commission for approval any tariff amendments necessary to effectuate the rule.

As part of each rulemaking proceeding required of the Commission under this section, the Commission shall ensure that there is a reasonable transition period for affected entities (as determined by the Commission), while seeking to avoid disruptions to existing projects or projects that are significantly underway.

On and after the effective date of the final rules issued under subsection (b) to establish the load interconnection queue system described in that subsection, a large load facility may only interconnect with the interstate transmission system once it has been approved through the applicable load interconnection queue system.
