By: Hall S.B. No. 2002
A BILL TO BE ENTITLED
AN ACT
relating to a limitation on the generation capacity provided for
the ERCOT power grid from wind and solar generation facilities.
BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF TEXAS:
SECTION 1. Section 39.159, Utilities Code, as added by
Chapter 426 (S.B. 3), Acts of the 87th Legislature, Regular
Session, 2021, is amended by amending Subsection (b) and adding
Subsection (d) to read as follows:
(b) The commission shall ensure that the independent
organization certified under Section 39.151 for the ERCOT power
region:
(1) subject to Subsection (d), establishes
requirements to meet the reliability needs of the power region;
(2) periodically, but at least annually, determines
the quantity and characteristics of ancillary or reliability
services necessary to ensure appropriate reliability during
extreme heat and extreme cold weather conditions and during times
of low non-dispatchable power production in the power region;
(3) procures ancillary or reliability services on a
competitive basis to ensure appropriate reliability during extreme
heat and extreme cold weather conditions and during times of low
non-dispatchable power production in the power region;
(4) develops appropriate qualification and
performance requirements for providing services under Subdivision
(3), including appropriate penalties for failure to provide the
services; and
(5) sizes the services procured under Subdivision (3)
to prevent prolonged rotating outages due to net load variability
in high demand and low supply scenarios.
(d) Beginning January 1, 2027, notwithstanding any other
law, if the commission determines that installed generation
capacity from wind and solar generation facilities is contributing
more than 20 percent of the available generation capacity for the
ERCOT power region, the commission shall:
(1) prohibit the interconnection of new wind and solar
generation facilities to the power grid; and
(2) by rule establish standards for the disconnection
of wind and solar power facilities from the power grid to ensure
that wind and solar generation is not contributing more than 20
percent of the available generation capacity for the ERCOT power
region at any time.
SECTION 2. This Act takes effect September 1, 2023.
