(A) In general
The term covered large load means a new or expanded nonresidential electric load, or a group of such loads under common ownership, control, or affiliation at a single site or at contiguous or adjacent sites sharing electric infrastructure (including phased development), that has an aggregate requested or projected peak electric demand of not less than 150 megawatts behind a single point of interconnection.
(B) Combined configurations
A load or group of loads described in subparagraph (A) shall be a covered large load without regard to whether it is proposed to be interconnected, studied, or served in combination with 1 or more generation or energy storage resources, and peak electric demand shall be measured without reduction for any such resource.

The term Network Upgrade means an addition, modification, or upgrade to the transmission system of a transmitting utility, at or beyond the point at which the Interconnection Facilities for a covered large load connect to that system, that is required to accommodate the interconnection of, or transmission service to serve, the covered large load, consistent with the definition of the term Network Upgrades in the standard interconnection procedures and agreements established by the Commission under section 35.28 of title 18, Code of Federal Regulations (or a successor regulation), as adapted by the Commission for covered large loads.
(9) Stand Alone Network Upgrade
The term Stand Alone Network Upgrade means a Network Upgrade classified as a Stand Alone Network Upgrade under the applicable tariff or service agreement accepted or approved by the Commission, consistent with the definition of the term Stand Alone Network Upgrades in the standard interconnection procedures and agreements established by the Commission under section 35.28 of title 18, Code of Federal Regulations (or a successor regulation), as adapted by the Commission for covered large loads.
(b) Jurisdiction over large load interconnection
(1) In general
The Commission shall have jurisdiction over the interconnection of any covered large load to 1 or more facilities used for the transmission of electric energy in interstate commerce.
(2) Treatment
The interconnection described in paragraph (1) shall be—
(A)
subject to the requirements of this section and sections 205 and 206; and
(B)
considered to be a component of open access transmission service.
(3) Included matters
The jurisdiction of the Commission under paragraph (1) includes—
(A)
flexible interconnection service, subject to enforceable operating limits;
(B)
provisional or phased interconnection service; and
(C)
the study and interconnection, separately or together, of a covered large load and any associated generation, energy storage, or verifiable load flexibility, including a dedicated resource.
(c) Rulemaking
(1) In general
Not later than 1 year after the date of enactment of this section, the Commission shall issue a final rule, applicable to each transmitting utility, establishing standards and procedures for the interconnection of covered large loads.
(2) Inclusions
The rule under paragraph (1) shall include pro forma provisions and regionally tailored requirements.
(3) Threshold criteria
The rule under paragraph (1) shall establish criteria and procedures for determining whether a load or group of loads is a covered large load.
(d) Required standards and procedures
The rule issued under subsection (c) shall establish standards and procedures governing each of the following:
(1) Study process
Timelines, readiness requirements, and study procedures for interconnection requests for covered large loads that—
(A)
protect other customers from the costs of speculative or duplicative requests;
(B)
(i)
identify reasonable alternatives, including the services and configurations described in subsection (b)(3) and advanced transmission technologies;
(ii)
present the alternatives, with estimated costs and schedules, to the covered large-load customer; and
(iii)
permit the covered large-load customer to elect among the alternatives in accordance with the applicable tariff; and
(C)
provide for the services and configurations described in subsection (b)(3), at the election of the covered large-load customer, where consistent with reliable operation of the bulk-power system.
(2) Classification and allocation of transmission costs
(A) Classification
