Summary

Use low-water cooling and report water use, or lose the tax deal and grid service.

The bill sets water, reporting and siting conditions on data centers that seek state school-tax limits, city or county tax abatements, or city loans and grants, and it lets the school-tax break for data centers be set at no more than half of market value. It touches large data centers of at least 100,000 square feet, the cities, counties and school districts that give them tax deals, the power utilities that connect them to the ERCOT grid, the Public Utility Commission, and the state environmental agency. On the ground, new data centers must use low-water cooling and report their water use, or they can lose their tax deals, be refused or cut off from grid service, and lose their construction stormwater permits.

Bill text, introduced version (I)

The bill orders utilities to cut off new data centers that use water-heavy cooling or skip annual water-use reports, and it ties their tax deals to the same cooling and reporting rules.

Bill text, introduced version (I)

For data centers, the bill changes the school-tax value limit from a flat 50 percent of market value to a ceiling of 50 percent, which leaves room for a deeper break, though the deal now comes with conditions.

systems at the time of interconnection; and

(B) the customer has submitted to the commission

the documentation required by Subsection (b); and

(2) require an electric cooperative, municipally

owned utility, or transmission and distribution utility to

disconnect a customer's campus from the ERCOT transmission grid if

the customer:

(A) uses a cooling system other than a

closed-cycle recirculating system, dry cooling system, saline

water cooling system, water-efficient cooling system, or

combination of those systems to cool a facility located on the

customer's campus, including any generation resource co-located on

the campus, while interconnected to the grid; or

(B) fails to timely submit to the commission the

documentation required by Subsection (c).

(g) The commission by rule may require a data center

customer to:

(1) limit the noise and light pollution caused by the

operation of any facility on the data center customer's site,

comprises the site.

(h) The commission by rule may:

(1) prohibit an electric cooperative, municipally

(2) require an electric cooperative, municipally

owned utility, or transmission and distribution utility to

disconnect a data center customer's site from the ERCOT
