A BILL TO BE ENTITLED
|
|
|
AN ACT
|
|
|
relating to a reliability assessment of the ERCOT power grid and |
|
|
certificates of public convenience and necessity for certain |
|
|
transmission projects. |
|
|
BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF TEXAS: |
|
|
SECTION 1. Section 37.052, Utilities Code, is amended by |
|
|
adding Subsection (c) to read as follows: |
|
|
(c) An electric utility is not required to amend the |
|
|
utility's certificate of public convenience and necessity to |
|
|
construct a transmission line that connects the utility's existing |
|
|
transmission facilities to a load-serving substation or metering |
|
|
point if: |
|
|
(1) the transmission line does not exceed three miles |
|
|
in length; |
|
|
(2) each landowner whose property would be directly |
|
|
affected by the transmission line, as provided by commission rules, |
|
|
provides written consent for the transmission line; and |
|
|
(3) all rights-of-way necessary for construction of |
|
|
the transmission line have been purchased. |
|
|
SECTION 2. Section 37.056, Utilities Code, is amended by |
|
|
adding Subsection (c-1) and amending Subsection (d) to read as |
|
|
follows: |
|
|
(c-1) In considering the need for additional service under |
|
|
Subsection (c)(2) for a reliability transmission project that |
|
|
serves the ERCOT power region, the commission must consider the |
|
|
following: |
|
|
(1) historical load, forecasted load growth, and |
|
|
additional load currently seeking interconnection; and |
|
|
(2) security constrained optimal power flows for a |
|
|
reasonable range of power generation dispatch scenarios, including |
|
|
reliability limitations in serving load during high and low |
|
|
renewable generation output. |
|
|
(d) The commission by rule shall establish criteria, in |
|
|
addition to the criteria described by Subsection (c), for granting |
|
|
a certificate for a transmission project that serves the ERCOT |
|
|
power region, that is not necessary to meet state or federal |
|
|
reliability standards, and that is not included in a plan developed |
|
|
under Section 39.904(g) [does not serve a competitive renewable |
|
|
energy zone]. The criteria must include a comparison of the |
|
|
estimated cost of the transmission project for consumers and the |
|
|
estimated congestion cost savings for consumers that may result |
|
|
from the transmission project, considering both current and future |
|
|
expected congestion levels and the transmission project's ability |
|
|
to reduce those congestion levels. The commission shall include |
|
|
with its decision on an application for a certificate to which this |
|
|
subsection applies findings on the criteria. |
|
|
SECTION 3. Subchapter D, Chapter 39, Utilities Code, is |
|
|
amended by adding Section 39.159 to read as follows: |
|
|
Sec. 39.159. GRID RELIABILITY ASSESSMENT. (a) The |
|
|
independent organization certified under Section 39.151 for the |
|
|
ERCOT power region shall conduct an annual assessment of the ERCOT |
|
|
power grid to assess the grid's reliability in extreme weather |
|
|
scenarios. |
|
|
(b) Each assessment must: |
|
|
(1) consider the impact of different levels of thermal |
|
|
and renewable generation availability; and |
|
|
(2) recommend transmission projects that may increase |
|
|
the grid's reliability in extreme weather scenarios. |
|
|
SECTION 4. The changes in law made by this Act apply only to |
|
|
a proceeding affecting a certificate of public convenience and |
|
|
necessity that commences on or after the effective date of this Act. |
|
|
A proceeding affecting a certificate of public convenience and |
|
|
necessity that commenced before the effective date of this Act is |
|
|
governed by the law in effect on the date the proceeding is |
|
|
commenced, and that law is continued in effect for that purpose. |
|
|
SECTION 5. This Act takes effect September 1, 2021. |
