HB 3970 Texas House · 89th Legislature (2025)

Relating to the interconnection and operation of large loads.

HB 3970 creates a priority interconnection program for large electricity consumers (facilities with over 75 megawatts of peak demand) in Texas. It requires the grid operator (ERCOT) to develop an expedited process for facilities that install on-site power generation (like solar or storage) and agree to stop drawing power from the grid during emergencies. The program gives these facilities faster approval for connecting their on-site generation and reduces their grid consumption when directed, while allowing parallel processing of their interconnection applications. This directly affects major industrial facilities, data centers, and large commercial sites seeking to reduce grid reliance during power shortages.

What changed between versions

Introduced Engrossed · 6 edits · May 1, 2025
MODERATE
The bill was substantially rewritten to create a new program for large loads in Texas to interconnect with the power grid more quickly. The original version focused on electricity planning for large loads, while the new version establishes specific requirements for large loads to provide behind-the-meter generation or flexible load capabilities to reduce grid demand during emergencies.
Scope change
The bill's scope expanded from general electricity planning for large loads to a specific interconnection and operation program for large loads that can reduce or eliminate their energy consumption from the grid through behind-the-meter generation or flexible load operations.
ELIGIBILITY

New eligibility criteria requiring large loads to either have behind-the-meter generation capable of serving full load requirements or have an aggregated peak demand of more than 75 megawatts at a single site.

REQUIREMENT

Large loads must bring behind-the-meter generation into service within 180 days after interconnection date or commit to flexible load status for at least 10 years.

ENFORCEMENT

New financial penalties for large loads approved for expedited interconnection that fail to reduce load or power load with backup generation as directed.

TECHNICAL

Program now allows studies for flexible loads to be evaluated as non-firm and counts demand reductions toward utility load shedding obligations during energy emergencies.

DEFINITION

Added formal definitions for 'behind-the-meter generation' and 'flexible load' to clarify program requirements.

TIMELINE

Established a 10-year minimum commitment period for flexible load status and 180-day timeline for bringing generation into service.
